The Litetronics® 185 and 320 W high bays offer the flexibility to address a variety of high ceiling applications. With a diffuser lens to deliver uniform light, the product addresses a wide variety of environments. The 2 ft long 185 W version offers 24100 lumens, making it an ideal upgrade for either 400 W metal halides or 324 W 6 tube T5Ho fixtures. The 4 ft, 320 W product is ideal for ceiling heights above 50 ft. Both carry lpw ratings of over 130. Designed for either pendant, chain or adjustable cable mounting, these linear high bays come with a 10 year warranty and a 100000 hour rated life . 0 to 10 V dimming makes the instant on fixtures ideal for use with daylighting or proximity sensors. The combination of an excellent initial value and long life means a short ROI and immediate freedom from the maintenance and light depreciation issues that make metal halide lighting in higher ceiling applications especially difficult and costly.
