3500K LED Troffer Kit

This 2 ft by 4 ft recessed troffer delivers 4,777 lumens at 3500K neutral white light. The integrated LED array operates at 35.7 watts maximum and achieves 133 lumens per watt. A Color Rendering Index of 82 provides accurate colour representation for commercial interiors. Dimming is supported on 120 to 277V AC supplies.

Offices needing efficient flat-panel light

The fixture replaces three-lamp T8 troffers without requiring a ballast, suiting retrofit projects that want simple installation. Integrated LEDs mean no lamp changes, but the design lacks an emergency battery backup and includes no sensor. Buyers who require standalone emergency operation or integrated occupancy control should consider other options.

DLC 5.0 Premium certified output

DesignLights Consortium 5.0 Premium listing confirms the kit meets high efficacy and quality thresholds for utility rebate programmes. The 4,777 lumen package at 133 lm/W satisfies the specification that drives eligibility in many commercial lighting projects. This single metric determines whether the troffer qualifies for the intended incentive.
