T5HO 47W UltraStart Watt-Miser System, GE Lighting
Designed for high-ceiling applications in commercial and industrial settings, the T5HO 47W UltraStart Watt-Miser System is best suited for high-bay or commercial troffer installations. A four-lamp system consumes 202W and delivers 95 lumens per watt, a 13 percent energy savings when compared to a 54W T5 system. The lamps are rated for 30,000 hours on a three-hour operating cycle. GE's UltraStart T5 ballasts operate the lamps in parallel mode, which keeps some lamps functioning when others fail. Additionally, the system is UL-certified to operate up to 55 C (131 F).
