LX2048 Series

Elegant fixed downlight designed specifically for the most demanding architecture applications.

The LumeLEX 2048 Series, an elegant fixed pendant downlight designed with Xicato XTM (19mm and 9mm), COB, Dim to Warm and Lumenetix-araya technology.  Developed specifically for the most demanding applications of hospitality lighting and transitional space lighting, the LumeLEX 2048 with Dim to Warm differentiates itself from the pack by providing 1800 lumens output with a system efficiency of 59 lumens/watt, a proprietary mixing optic for smooth even light (15°- 50°), Halogen mimicking color CCT from 2800°K down to 2000°K and a full range of internal accessories.

The LumeLEX 2048 Series can be used with our versatile CONTROLTrack™ system to be controlled with either 0-10V or DMX protocols and dimmable to 1%.  The LSI CONTROLTrack™ option allows for unparalleled flexibility for controlling an entire track run or individual fixtures from a simple wall device, all the way through the most sophisticated control systems.

LED module and driver are field replaceable.
