Efficiency Plugs!
These accessories simply plug into Indak’s troffers to change the light output. Because LEDs become more efficient when they are under-driven, they also control efficiency. Indak troffers come preset to 60% of their maximum output. This yields an “efficacy” of 100 Lumens per Watt . If more brightness is needed, simply install an 80% (yellow) or 100% (red) efficiency plug. If you prefer less light and power consumption with greater efficiency, insert a black (40%) efficiency plug.

Magnetic Mounts!
Indak’s under-cabinet Task Lights are available with magnetic mounts, so installing them under steel shelves (common in office cubicles) is extremely quick and easy.

Lighting Facts!
Lighting Facts is a program of the U. S. Department of Energy. Several of Indak’s troffers are now registered with Lighting Facts, verifying their efficiency and color accuracy. See for more information.
