SL-FL Series Solar Flood Light
Solar flood light projects often fail on runtime expectations, panel orientation limits, and unclear battery sizing. SL-FL is a configuration-ready series designed for perimeter and site lighting, with DC 12/24V architecture, LiFePO4 battery options, and monocrystalline panel options—so you can match season and operating mode without guessing.
Product Features
- Configuration-ready sizing: battery and panel options to match runtime expectations and local solar conditions
- DC 12/24V system: simplified system integration and troubleshooting
- Outdoor durability: IP66 protection with IK10 impact rating
- Use cases: perimeter, yard, site entrances, and security lighting
- Reduced onsite rework: configuration notes can be provided based on mounting and operating mode
| Series | SL-FL Series (Solar Flood Light) |
| Power Range | 20W–150W (by configuration) |
| Luminous Efficacy | 140–170 lm/W (by configuration) |
| Input Voltage | DC 12/24V |
| Battery Spec | LiFePO4 lithium, 230Wh–1843Wh or customized |
| Solar Panel Spec | Monocrystalline silicon, 50–400W or customized |
| IP Rating | IP66 |
| IK Rating | IK10 |
Note: Runtime depends on operating mode, season, and panel orientation. Battery and panel sizing should be confirmed by site conditions.
Installation Support
To reduce installation mistakes and onsite rework, we provide a step-by-step installation manual pack for this series . If you want faster fitment confirmation, send your pole diameter, mounting height, and bracket photos — our team can guide you remotely and confirm the correct setup before deployment.
Optics Options (Type II / Type III / Type IV)
Best for narrower roads and longer forward throw. Helps keep light focused along the roadway.
Type II • Narrow roads • Long throw • Controlled spill
A general-purpose distribution for most standard roads. Balanced forward throw and side coverage.
Type III • Standard roads • Balanced coverage • Common choice
Designed for wider roads, perimeters, and edge coverage. Useful when you need more lateral reach.
Type IV • Wider roads • Perimeter • Lateral reach
Not sure which optic fits your road width and mounting height? Send your height and target spacing — we’ll confirm the best option.

Frequently Asked Questions
How do I choose the right battery and panel configuration? +
Start with your required working hours, operating mode, and the worst-season solar condition. Panel orientation and shading matter. We match battery Wh and panel W to your runtime target to avoid undersizing.
Will it run more than 12 hours every night? +
Runtime depends on operating mode, season, and panel exposure. A constant full-output profile will shorten runtime. For stable operation, confirm the mode and size the battery/panel for the local worst-season condition.
Why do DC 12/24V systems matter for installation and troubleshooting? +
A DC 12/24V architecture keeps wiring and checks straightforward, especially for replacement or onsite diagnostics. Confirm your preferred voltage and wiring path before installation.
Is the SL-FL series suitable for harsh outdoor environments? +
The series is built for outdoor use with IP66 protection and IK10 impact rating. For coastal or high-corrosion sites, confirm the mounting hardware and site conditions for the right configuration.
What documents can you provide for deployment and approvals? +
A project-ready set can include datasheet, configuration notes (battery/panel/mode assumptions), and packing list on request. Clear assumptions reduce clarification cycles and rework.
