The light levels you need
-
The RTL is available in a wide variety of lumen output packages to ensure you get the exact light level you need. Frosted diffuser lenses (pictured) are optional, and are ideal for louvered troffers to help minimize glare and improve aesthetics. Replacement lenses are also available for order for troffers with lensed doors (see spec sheet for details).
