High Mast Light Wattage Guide: 400W, 600W, 800W & 1000W Selection

Quick Answer

High mast light wattage should not be selected by watts alone.

A 400W, 600W, 800W or 1000W LED high mast light may be suitable for different projects depending on the required maintained lighting level, rated luminaire lumens, luminaire efficacy, optical distribution, candela intensity in the required aiming direction, pole height, pole spacing, aiming angle, maintenance factor and DIALux or equivalent photometric calculation.

Wattage is only the electrical input power. It does not prove ground illuminance, long-throw performance, glare control, uniformity or coverage area.

For RFQ and tender comparison, the buyer should compare:

• Rated luminaire input power.
• Rated luminaire lumens.
• Luminaire efficacy for the exact CCT, CRI, optic and drive-current configuration.
• IES/LDT photometric file.
• Candela distribution and beam type.
• Maintained average illuminance.
• Minimum illuminance.
• Uniformity convention.
• Glare and spill-light limits.
• Luminaire quantity per mast.
• Fixture weight, EPA and headframe load.
• Driver, surge protection, circuit and control requirements.

A lower-wattage luminaire with better optics and verified photometry may outperform a higher-wattage luminaire with poor distribution. The final wattage should be confirmed by IES/LDT files, DIALux calculation and project-specific RFQ requirements.

Why Wattage Alone Cannot Define High Mast Lighting Performance

Wattage describes electrical input power. It tells you how much power the luminaire consumes.

It does not directly tell you:

• How much rated light output the complete luminaire provides.
• How much useful light reaches the target area.
• Whether the beam reaches the required distance.
• Whether the ground illuminance is uniform.
• Whether the fixture creates glare toward drivers, operators or nearby properties.
• Whether the selected optics fit the site geometry.
• Whether the result meets maintained lux and uniformity requirements.
• Whether the installation can reproduce the photometric calculation.

Two 800W LED high mast lights can perform very differently if they have different:

• Rated luminaire lumens.
• Luminaire efficacy.
• Optical distribution.
• Candela intensity distribution.
• Beam angle or asymmetric optic.
• Thermal design.
• Driver setting.
• CCT and CRI configuration.
• IES/LDT photometric file.
• Fixture size, weight and EPA.

A wattage recommendation without photometric data is only a preliminary estimate.

If the project team has not yet defined the required lighting level, review the High Mast Lighting Level Specification Guide before finalizing wattage.

Rated Lumens, Luminaire Efficacy and Input Power

For wattage comparison, use luminaire efficacy, not LED-chip efficacy.

A complete high mast luminaire includes LEDs, optics, thermal structure, driver, housing and electrical losses. Therefore, LED-chip efficiency or LED-module efficiency should not be substituted for complete-luminaire performance.

Use consistent data types when comparing wattage, lumens and efficacy.

If the values come from product ratings, use rated values:

Rated luminaire lumens ≈ rated input power × rated luminaire efficacy

If the values come from the same laboratory test, use measured values:

Luminaire efficacy = measured luminous flux ÷ measured input power
Measured luminous flux = measured input power × measured luminaire efficacy

For concept discussion only:

600W × 170 lm/W ≈ 102,000 lm
800W × 170 lm/W ≈ 136,000 lm
1000W × 170 lm/W ≈ 170,000 lm

This is only a mathematical relationship. Real products must be checked by the manufacturer’s rated luminaire lumens and rated input power for the exact configuration.

The rated value may vary by:

• CCT.
• CRI.
• Optic.
• Drive current.
• Ambient temperature rating.
• Driver setting.
• Thermal design.
• Test method.
• Manufacturing tolerance.

Do not use a marketing claim for LED-chip efficacy as the luminaire efficacy of a complete high mast light. For formal project comparison, request the datasheet, IES/LDT file and, where required, an LM-79 test report for the exact luminaire configuration, preferably issued by a competent or accredited laboratory.

LM-79 is a photometric and electrical measurement method. It is not a product certification by itself. The report should match the proposed wattage, CCT, CRI, optic, driver setting and drive current.

Lumen Output Examples at Different Efficacy Levels

The following table is a mathematical comparison only. It is not a product promise and should not be used as a guaranteed project result.

Wattage	140 lm/W	170 lm/W	190 lm/W
400W	56,000 lm	68,000 lm	76,000 lm
600W	84,000 lm	102,000 lm	114,000 lm
800W	112,000 lm	136,000 lm	152,000 lm
1000W	140,000 lm	170,000 lm	190,000 lm
1200W	168,000 lm	204,000 lm	228,000 lm

This table helps explain why wattage alone is not enough.

For example, an 800W luminaire at 140 lm/W produces approximately the same rated lumen package as a lower-wattage luminaire with higher efficacy. The final lighting result still depends on optics, candela distribution, mounting height, aiming and calculation geometry.

Common LED High Mast Light Wattages

LED high mast luminaires are commercially available in many power ranges. The following sections describe how 400W, 600W, 800W, 1000W and 1200W+ options are normally reviewed during project selection.

These are not fixed rules; the same mast height can use different luminaire quantities, wattages and optics.

400W High Mast Light

A 400W LED high mast light may be reviewed where the required lumen package is moderate, the target zone is smaller, or multiple luminaires are used for more controlled aiming.

Potential review cases include:

• Lower mounting heights.
• Smaller target zones.
• Parking or boundary areas.
• Supplementary aiming positions.
• Projects where overlighting and spill light must be controlled.
• Multi-luminaire layouts where distribution flexibility is more important than maximum output per fixture.

Key checks:

• Rated luminaire lumens.
• Beam distribution.
• Minimum illuminance.
• Uniformity.
• Glare from observer positions.
• Whether more fixtures are needed to meet the target.

Lower wattage may reduce available output, but it does not guarantee lower glare. Glare must be evaluated from luminaire intensity, apparent source size, optics, aiming and observer position.

600W High Mast Light

A 600W LED high mast light is often reviewed as a medium-output option in multi-luminaire high mast systems.

It may be useful when a project needs a balance between output, fixture count and aiming flexibility.

Potential review cases include:

• Medium high mast layouts.
• Logistics or industrial yards.
• Parking and circulation areas.
• Multi-fixture headframes.
• Projects comparing more medium-output luminaires against fewer high-output luminaires.

Key checks:

• Rated lumen output for the exact product.
• IES/LDT file.
• Target-zone distribution.
• Fixture quantity per mast.
• Driver quantity and circuit design.
• Beam overlap and uniformity.

A 600W luminaire with a narrow or asymmetric optic may deliver stronger intensity in a required aiming direction than a higher-wattage wide-beam luminaire. Therefore, long-throw performance should be judged by target-direction candela distribution and IES/LDT intensity data, not wattage alone.

800W High Mast Light

800W LED high mast lights are commercially available for high-output area and infrastructure lighting, but mounting height alone does not establish their suitability.

An 800W option may be reviewed for projects that require a stronger lumen package while still maintaining practical luminaire quantity and aiming control.

Potential review cases include:

• Logistics yards.
• Port or terminal yards.
• Industrial sites.
• Large outdoor parking areas.
• Mining or heavy-equipment yards.
• High mast layouts requiring medium-to-high lumen output per fixture.

Key checks:

• Luminaire efficacy and rated lumens.
• Candela distribution in the required aiming direction.
• Beam angle and optical type.
• Maintained lux and minimum lux.
• Uniformity.
• Glare and spill light.
• Fixture weight and EPA.

An 800W option should not be treated as a universal answer for 25m, 30m or 35m high mast lighting. It should be compared with other wattage and luminaire quantity combinations under the same calculation conditions.

1000W High Mast Light

A 1000W LED high mast light may be considered when the project requires a higher rated lumen package or when fewer luminaire positions are preferred.

However, a 1000W option is not automatically better than an 800W or 600W option.

Potential review cases include:

• Large yards.
• Port and logistics areas.
• Heavy industrial zones.
• Large transport or terminal areas.
• Projects requiring a higher output per luminaire.

Key checks:

• Rated luminaire lumens.
• Candela distribution.
• Heat dissipation.
• Glare from observer positions.
• Spill-light control.
• Electrical load.
• Driver characteristics.
• Fixture size, weight and EPA.
• Headframe arrangement.

A 1000W luminaire with poor optics may create hot spots, glare or poor uniformity. A multi-luminaire solution using lower wattage may sometimes deliver better target-zone control.

1200W and Above High Mast Lights

1200W and above LED high mast lights should be treated as project-specific high-output options.

They may be used in special infrastructure applications, but they require stronger engineering review.

Key checks include:

• Complete luminaire photometry.
• Thermal performance.
• Driver design.
• Surge protection.
• Actual input power.
• Rated luminaire lumens.
• Fixture weight.
• Dimensions.
• Effective projected area.
• Mounting arrangement.
• Headframe and lowering-system compatibility.

High-output luminaires may be larger or heavier, but structural impact must be checked using the actual fixture weight, dimensions, effective projected area and mounting arrangement. Wattage alone does not determine wind load or headframe load.

Wattage Comparison Table

The following table summarizes wattage review logic. It is not a final design table.

LED Wattage	Typical Review Use	Main Advantage	Main Risk	Must Verify
400W	Moderate-output zones, smaller target areas, supplementary aiming	Lower input power and flexible zoning	May require more fixtures	Rated lumens, minimum lux and uniformity
600W	Medium-output multi-luminaire layouts	Balance between output and aiming flexibility	May not meet target if optics or lumen package are insufficient	IES/LDT, candela distribution and target-zone result
800W	High-output area-lighting comparisons	Stronger lumen package per fixture	Can still fail if beam distribution or aiming is unsuitable	Beam angle, aiming, maintained lux and glare
1000W	Larger output per luminaire where justified	Higher rated lumen package	Higher heat, glare, electrical and cost impact may occur	Luminaire photometry, thermal data, glare and electrical design
1200W+	Project-specific high-output applications	Very high output per fixture	Requires stronger photometric, electrical and structural review	Datasheet, applicable test report, IES/LDT, weight, EPA, driver and headframe compatibility

How Pole Height Affects Wattage Selection

Pole height affects wattage selection because mounting height changes the geometry between the luminaire and the target area.

When mounting height changes, the design may require different:

• Lumen package.
• Beam distribution.
• Candela intensity in the aimed direction.
• Tilt angle.
• Number of luminaires.
• Pole spacing.
• Glare control method.
• Target-zone overlap.

A taller mast may support wider area lighting, but it does not automatically require a specific wattage. A lower-output luminaire with a suitable optic may work in one layout, while a higher-output luminaire may fail in another layout if the beam distribution is wrong.

For height selection logic, review the High Mast Pole Height Guide.

How Lux Target Affects Wattage Selection

The required maintained lighting level is one of the most important wattage inputs.

A higher maintained illuminance requirement may increase the required lumen package, luminaire quantity or wattage. A stricter minimum illuminance or uniformity target may also require more overlap between luminaires.

However, wattage should not be increased blindly.

If the problem is poor uniformity, the solution may be:

• More suitable optics.
• More luminaires with lower wattage.
• Better aiming.
• Different pole locations.
• Revised spacing.
• Better zone division.

If the problem is glare, adding wattage may make the design worse.

Before wattage is selected, define:

• Maintained average illuminance.
• Minimum illuminance.
• Uniformity convention.
• Maintenance factor.
• Calculation plane.
• Calculation area.
• Glare or spill-light requirements.

For lighting-level specification, review the High Mast Lighting Level Specification Guide.

How Optics, Beam Angle and Candela Affect Wattage

Optics can be more important than wattage.

A luminaire with suitable optics may deliver useful light into the target area more effectively than a higher-wattage luminaire with poor distribution.

Long-throw performance should be compared using the candela distribution and IES/LDT intensity data in the required aiming direction, not wattage or total lumens alone.

For example:

• A narrow-beam 600W luminaire may have higher intensity in a specific direction than a wide-beam 1000W luminaire.
• A wide-beam luminaire may improve nearby distribution but may not provide enough long-distance target intensity.
• An asymmetric optic may perform better for roadways, perimeter zones or yard edges than a symmetric optic.
• Poor tilt or rotation can waste light even if the wattage is high.

The design should review:

• Candela distribution.
• Beam angle.
• Symmetric or asymmetric optics.
• Tilt and rotation.
• Target-zone coverage.
• Glare toward observers.
• Spill light beyond the boundary.
• Uniformity in the calculation grid.

A wattage table cannot replace an IES/LDT-based calculation.

Glare Is Not Determined by Wattage Alone

Higher wattage may increase available output, but wattage alone does not determine glare.

Glare depends on:

• Luminaire intensity in the observer’s direction.
• Apparent source size.
• Optics.
• Lens and shielding design.
• Mounting height.
• Tilt angle.
• Observer position.
• Viewing direction.
• Background brightness.
• Spill-light control.

Lower wattage may reduce available output, but it does not guarantee lower glare. A poorly aimed 400W luminaire can create more discomfort than a well-controlled higher-output luminaire.

Therefore, glare should be reviewed by observer positions and photometric data, not by wattage label.

How Many Luminaires Should Be Installed on One High Mast?

High mast lighting systems usually use multiple luminaires on one mast.

The number of luminaires per mast depends on:

• Pole height.
• Headframe design.
• Required light output.
• Target zones.
• Beam distribution.
• Aiming plan.
• Glare control.
• Fixture weight.
• Effective projected area.
• Lowering-system capacity.
• Electrical circuit design.
• Driver quantity.
• Maintenance access.

A 30m mast might use 4, 6, 8, 10, 12 or more luminaires depending on project requirements.

The correct number is not determined by mast height alone.

Fewer high-output luminaires may simplify fixture count, but they may reduce aiming flexibility. More medium-output luminaires may improve target-zone control, but they may increase fixture quantity, wiring, driver count and maintenance points.

Decision Framework: 6×800W vs 8×600W

One of the most useful high mast comparisons is whether to use fewer higher-wattage luminaires or more medium-wattage luminaires.

The following comparison is a decision framework only. It is not a final lighting calculation.

Item	6×800W Option	8×600W Option	Why It Matters
Total input power	4800W	4800W	Same total wattage does not guarantee same lighting result
Total rated lumens	Depends on luminaire efficacy	Depends on luminaire efficacy	Same wattage does not mean same output
Luminaire efficacy	Must be verified	Must be verified	Defines rated lumen difference
Fixture count	Lower	Higher	Affects aiming, maintenance and wiring
Aiming flexibility	Usually lower	Usually higher	More fixtures can create more target zones
Headframe complexity	Usually simpler	Usually more complex	Affects fabrication and serviceability
Target-zone control	Depends on optics and aiming	Often more flexible	Important for uniformity and edge coverage
Driver quantity	Fewer drivers	More drivers	Affects failure points and service planning
Inrush current	Must be checked	Must be checked	Driver count can affect circuit design
Circuit current	Must be calculated	Must be calculated	Supports cable and breaker sizing
Total fixture weight	Depends on product	Depends on product	Affects headframe and lowering system
Total effective projected area	Depends on fixture dimensions and quantity	Depends on fixture dimensions and quantity	Affects wind-load review
Failure impact	One failed fixture removes a larger share of output	One failed fixture removes a smaller share of output	Affects lighting resilience
Fixture cost	Product-specific	Product-specific	More fixtures can increase equipment cost
Replacement access	Fewer units	More units	Affects maintenance time
Final decision	Use IES/LDT and DIALux	Use IES/LDT and DIALux	Photometric result controls selection

Both options have the same total input power, but they may not produce the same lighting result.

The final comparison must check:

• Rated luminaire lumens.
• Candela distribution.
• Optics.
• Maintained lux.
• Minimum lux.
• Uniformity.
• Glare.
• Total headframe load.
• Effective projected area.
• Electrical circuit design.
• Lifecycle maintenance.

Total headframe load depends on fixture weight, fixture quantity, effective projected area and mounting arrangement, not wattage alone.

Verified Luminaire Comparison Template

If two products have the same wattage, compare the verified product data instead of assuming equal performance.

Use this table only with real datasheets, IES/LDT files and applicable test reports. Where LM-79 data is required, confirm that the report is for the exact luminaire configuration.

Parameter	Luminaire A	Luminaire B
Rated input power	—	—
Measured or rated luminaire lumens	—	—
Luminaire efficacy	—	—
CCT / CRI	—	—
Optic type	—	—
Beam distribution	—	—
Peak intensity and intensity at required C/γ or aiming angles	— cd	— cd
Fixture weight	—	—
Effective projected area	—	—
Surge protection	—	—
Power factor	—	—
THD	—	—
Ambient rating	—	—
IES/LDT file	Yes / No	Yes / No
Applicable test report	Yes / No	Yes / No

Peak intensity alone is not enough. The comparison should check intensity in the required C/γ or aiming directions, using the same photometric coordinate system and optic configuration.

This comparison is especially useful for 800W vs 800W or 1000W vs 1000W supplier evaluation. The same wattage can still produce different DIALux results.

IES/LDT Files Must Be Cross-Checked

An IES or LDT file is required for DIALux or Relux simulation, but the file itself does not prove that the luminaire output and efficiency have been independently tested.

Before accepting a photometric file, cross-check:

• Total luminaire lumens in the IES/LDT file.
• Rated input power.
• CCT and CRI.
• Optic type.
• Driver setting.
• Drive current.
• Product model and configuration.
• Datasheet values.
• Applicable test report values.

A photometric file should not be accepted only because it imports successfully into DIALux. The file must match the proposed luminaire configuration used in the quotation and BOQ.

Power-Selectable or Dimmed Luminaires

Some high-power LED luminaires support multiple power settings, such as 400W, 600W, 800W or 1000W configurations.

For power-selectable or dimmed luminaires, request the photometric file and rated data for the proposed setting.

Do not scale another wattage configuration unless the manufacturer confirms that proportional photometric scaling is valid for that product and operating condition.

For example, a 1000W IES file scaled to 800W may not accurately represent thermal behavior, drive current, optical output, driver efficiency or lumen maintenance unless the manufacturer’s photometric data supports that method.

Short Note on HID Replacement and LED Retrofit

Some users search for high mast wattage because they want to replace metal halide, high-pressure sodium or other HID high mast lights with LED.

This is a valid project need, but HID replacement should not be handled by a simple wattage equivalence chart.

For example, replacing a 1000W metal halide high mast light does not automatically mean selecting a 400W or 600W LED fixture. The correct LED option depends on:

• Existing luminaire output.
• Existing optical distribution.
• Pole height.
• Existing aiming.
• Current measured lighting level.
• Required maintained lux.
• New LED luminaire efficacy.
• New candela distribution.
• Electrical system.
• Retrofit bracket or headframe design.
• Thermal and mechanical compatibility.

This article focuses on LED high mast wattage selection. HID replacement and LED retrofit should be reviewed separately.

Electrical and Driver Parameters for Wattage Review

For RFQ and BOQ comparison, wattage selection should include electrical review.

A supplier should provide:

Electrical Item	Why It Matters
Rated input voltage and frequency	Confirms compatibility with project power supply
Actual input power	Supports energy and circuit calculation
Power factor	Affects electrical efficiency and supply design
THD	Supports power-quality review
Driver efficiency	Affects total performance and heat
Inrush current	Important when many drivers start together
Surge protection rating	Critical for outdoor high mast installations
Circuit quantity	Affects panel, cable and breaker design
Branch-circuit current	Supports cable sizing and protection
Dimming or control protocol	Required for smart or scheduled dimming
Ambient-temperature derating	Confirms operation in hot environments
Driver location	Affects maintenance and thermal conditions

For example, 6×800W and 8×600W may have the same total input power, but driver quantity, inrush current, circuit arrangement and maintenance planning may be different.

Why Higher Wattage Is Not Always Better

Higher wattage may increase the available lumen package, but it can also create problems when optics and aiming are not controlled.

Possible issues include:

• More energy consumption.
• Higher heat load.
• Higher equipment cost.
• Larger or heavier fixtures.
• More difficult glare control in some observer directions.
• More spill light beyond the boundary.
• Hot spots near mast locations.
• Poor uniformity if the beam is unsuitable.
• Larger electrical and surge-protection requirements.

In some projects, the better solution is not higher wattage.

The better solution may be:

• More suitable optics.
• Different candela distribution.
• More luminaires with lower wattage.
• Improved aiming plan.
• Different pole spacing.
• Revised pole placement.
• Better functional zoning.
• Correct maintenance factor.
• Improved DIALux model.

The goal is not to use the highest wattage. The goal is to meet the required lighting performance efficiently and safely.

What Should Be Verified in DIALux?

A high mast wattage proposal should be verified in DIALux, Relux or equivalent lighting software before final approval.

The report should confirm:

Report Item	What to Check
Luminaire model	Is the selected product used?
Rated input power	Does it match the proposed product?
Rated luminaire lumens	Is the correct lumen package applied?
Luminaire efficacy	Does it match the tested or rated configuration?
IES/LDT file	Is the actual photometric file used?
IES/LDT cross-check	Do lumens, wattage, CCT, CRI, optic and driver setting match the datasheet and applicable test report?
Power setting	If the luminaire is dimmed or power-selectable, is the file for the proposed setting?
Candela distribution	Does it support the required C/γ or aiming direction, not only peak intensity?
Pole height	Does it match the actual mounting height?
Luminaire quantity	Is the number per mast correct?
Aiming	Are tilt and rotation realistic?
Maintenance factor	Is maintained lux being calculated?
Average lux	Does it meet the project target?
Minimum lux	Are dark zones acceptable?
Uniformity	Is the correct convention used?
Glare	Are drivers, operators or neighbors affected?
Spill light	Is light controlled outside the project area?
Calculation grid	Does it match the real lighting scope?

A proposal that lists only “800W high mast light” or “1000W high mast light” is incomplete for engineering review. A photometric file should also be checked against the datasheet and applicable test report before it is used as the basis for procurement.

Sunlurio can support DIALux simulation outputs and IES/LDT photometric files when project information is available.

Common Wattage Selection Mistakes

Mistake	Why It Creates Risk	Better Review Method
Choosing by wattage only	Watts do not define lighting performance	Compare rated lumens, optics and DIALux results
Using LED-chip efficacy	It may overstate complete-luminaire performance	Use luminaire efficacy for the exact product configuration
Assuming all 800W lights are equal	Efficacy, optics and photometry may differ	Review datasheet, IES/LDT and test report
Using higher wattage to solve every problem	May increase heat, cost, glare or spill light	Review optics, aiming and layout first
Judging long throw by watts	Throw depends on target-direction candela distribution	Review IES/LDT intensity data at the required aiming direction
Accepting an IES file without cross-checking	Imported files can still mismatch the quoted configuration	Compare IES/LDT lumens, wattage, CCT, CRI, optic and driver setting against datasheet and test data
Scaling a different wattage file without confirmation	Power-selectable products may not scale proportionally	Request photometric data for the proposed setting
Assuming lower wattage guarantees lower glare	Glare depends on intensity, source size, optics and observer position	Perform glare review
Comparing only total watts per mast	Same total power can produce different distribution	Compare target-zone performance
Ignoring maintained lux	Long-term performance may be overstated	Use maintenance factor
Ignoring fixture weight and EPA	Structural impact is not defined by wattage	Check actual fixture data
Ignoring driver and circuit design	Same wattage can have different electrical behavior	Review driver data and circuit current
Finalizing BOQ before simulation	Equipment quantities may change later	Verify with DIALux before procurement

Frequently Asked Questions

How many watts should a high mast light be?

There is no single wattage for all high mast projects. Common LED options include 400W, 600W, 800W, 1000W and 1200W+, but the correct wattage depends on rated luminaire lumens, optics, candela distribution, pole height, lux target, uniformity, aiming, electrical design and DIALux verification.

Is 800W enough for a high mast light?

800W may be suitable for some projects, but it is not guaranteed. The result depends on luminaire efficacy, rated lumens, beam distribution, pole height, spacing, aiming and required maintained lux.

Is 1000W better than 800W?

Not always. A 1000W luminaire may provide more output, but it may also increase heat, cost, electrical load or glare risk if optics and aiming are not suitable. A well-designed 800W or 600W multi-luminaire layout may perform better in some projects.

What is the difference between watts and lumens?

Watts measure electrical input power. Lumens measure light output. For high mast lighting, rated luminaire lumens and photometric distribution are more useful than wattage alone.

What is luminaire efficacy?

Luminaire efficacy is the light output of the complete luminaire divided by its input power. Use rated values with rated values, or measured values from the same test report. It is more relevant than LED-chip efficacy because it includes optical, thermal and driver-related losses.

How many lumens does an 800W high mast light produce?

It depends on luminaire efficacy. As a mathematical example, an 800W luminaire at 140 lm/W produces about 112,000 lumens, while an 800W luminaire at 190 lm/W produces about 152,000 lumens. The actual value must come from the product datasheet and test data.

Should I use 6×800W or 8×600W on one mast?

Both options may use the same total input power, but they can produce different lighting results. Compare total rated lumens, optics, candela distribution, aiming flexibility, driver quantity, fixture weight, EPA, circuit design, maintained lux, uniformity and glare.

Can wattage determine coverage area?

No. Coverage depends on lumens, optics, candela distribution, pole height, aiming, spacing, maintained lux target and site geometry. Wattage alone cannot define coverage area.

Can I replace metal halide high mast lights using a simple LED wattage chart?

Not reliably. HID replacement depends on the existing luminaire, pole height, optics, current lighting level, LED photometry and target maintained lux. Retrofit projects should be reviewed separately.

Do I need IES files for wattage selection?

Yes. IES or LDT files are required to simulate how the selected luminaire distributes light. Without photometric files, wattage selection is only a preliminary estimate.
