Prescolite MegaLum; Prescolite 6-in. LiteBox LED Downlight Module

Prescolite MegaLum Litebox LED

The Prescolite MegaLum is the commercial lighting industry’s first recessed LED downlight to deliver 12,000 lumens, all from an 8-in. aperture. MegaLum features 4 lumen packages and 4 beam spread options for virtually any ceiling height. Using heat pipe technology – the same used in high performance computers, HVAC systems and solar products – MegaLum employs hundreds of low-power LEDs to exceed the thermal management and beam pattern performance of any other recessed downlight on the market.

With only 168 watts of input, MegaLum is a powerful replacement for high-watt incandescent or HID/induction fixtures. MegaLum saves up to 30% of system watts vs. a 250W metal halide and up to 75% vs. a 500W T4 quartz fixture. It also saves on maintenance costs; the driver and light engine are completely accessible from above or below the ceiling plane, and the luminaire’s anodized reflectors are field interchangeable.

The Prescolite LiteBox is a premiere downlight solution for light commercial environments. It comes with a screw base adapter that fits new or existing 6-in. recessed housings, and provides 1,000-lumen output and distribution – comparable to a 75W PAR lamp – while consuming only 12 watts of energy and delivering an outstanding efficacy at 87 lumens per watt.
