FEATURES & SPECIFICATIONS Intended Use The LEN offers the look and feel of a fluorescent luminaire - subtle soft direct elements, interest and depth across the ceiling plane - with a contemporary look that blends with today s commercial spaces. Combined with LED Array and drives, this series offers state-of-the-art lighting performance, energy efficiency and reduced maintenance. The frosted acrylic lens provides a diffused luminance, with the effective combination of excellent light transmission and haze. Applications For recessed commercial applications such as offi ces, hospitals, schools, etc. Suitable for use in standard 15/16 inverted T-bar grid ceilings. LED Array Features High performance optical engine delivers main beam focus through the integrated acrylic lens Lumieo acrylic diffuser manages the balance of efficiency and aesthetics Linear arrayed LED modules provide diffused, but effective illumination LED light engine (optional) by LG Innotek, global leader in LED technology and others UL and DLC Listed Housing Low Profile body with matte white sloped side members Direct Optical Component High performance optical engine Diffuser Surround Lumieo acrylic diffuser center V adds character to the optical assembly Luminaire Type Recessed troffer fi xture body assembly 2 x2 and 2 x4 size LED Light Source LED light engine includes 50 chip board and matched driver from LG Innotek. 0 to 10 volt Dimming Driver ORDERING INFORMATION Item No. Dimensions Description LEN22L36W3228LDMV40K 23.9"L x 23.9"W x 3.7"H 36W, 3228 Lumens, 4000K; 0-10V Dimming LEN24L52W5125LDMV40K 23.9"L x 47.9"W x 3.7"H 52W, 5125 Lumens, 4000K; 0-10V Dimming Consult for other wattages, lumens and kelvin temperatures.
