Construction Site LED Lighting
An advanced low-voltage temporary lighting system. Specification-grade LED performance with the safety profile of a 27.5VDC Class 2 circuit.
Construction Lighting Is Broken. We Fixed It.
Temporary construction lighting hasn’t changed in decades — line-voltage stringers daisy-chained through wet, damaged corridors. OSHA still lists electrocution among construction’s “Fatal Four.” FLEX SLS 3.0 reclassifies the entire hazard profile.
Electrocution risk
FLEX SLS runs on 27.5VDC — same class as automotive lighting. Effectively zero shock risk, even in wet conditions.
System-level efficiency
Even against line-voltage LED stringers, FLEX wins on architecture: FM2A modules draw just 6W per fixture, and one centralized FPS550 power supply replaces a separate driver on every string — up to 68 modules on 680’ of bus line, with 3kV surge protection built in.
Speed of deployment
Twist-and-lock T-Connectors eliminate splices, and modules reconfigure on-site as work progresses. Embedded CDB1 deck boxes pre-route the bus line so the install crew moves faster on pour day.
OSHA & code requirements
Operating below the 50V Class 2 threshold means no GFCI requirement and no LOTO procedures for repositioning. Backed by ETL Listed listing on the FPS550 power supply.
Project-scale flexibility
Modular system scales from a small renovation to a 50-story high-rise by adding modules and power supplies.
Worker safety
Construction-grade housings handle drops and impacts; surfaces stay warm, never hot — safe to touch, safe near materials.

Snap. Connect. Illuminate.
The FLEX SLS 3.0 modular system makes construction site lighting as simple as it should be.
1. Snap Together
Modular light modules connect with tool-free snap connections. No wire nuts, no junction boxes, no conduit. Any laborer can do it.
2. Connect Power
Daisy-chain multiple modules from a single 27.5VDC power supply. Scale from one room to an entire floor in minutes.
3. Illuminate Safely
Full illumination at 27.5VDC. Zero electrocution risk. Warm to the touch. OSHA compliant out of the box. Relocate as the build progresses.
