Terralux has released DRVH, an energy-efficient LED retrofit kit for 8- to 12-inch commercial downlights that utilize vertically mounted Compact Fluorescent or High Intensity Discharge bulbs. The self-contained retrofit kit reuses the original downlight fixture in high ceiling, atrium and canopy applications. The DRVH is warrantied for 10 years, even in 24/7 run-time applications. All models are ENERGY STAR-certified as Luminaire Retrofit Kits, which qualifies them for utility rebates. DRVH is UL1598C certified as an LED Retrofit Kit, which allows field installation into existing UL-certified downlight fixtures to retain their UL certification after being upgraded to LED.
