More Info

PENTRON® HO SuperSaver® T5 lamps operate on standard T5 HO programmed rapid start systems, in order to save energy over existing T5HO systems. When compared with existing 54 W T5HO lamps, the 47 W lamp offers energy savings of up to 13% while maintaining 92% of light output and the 50 W lamp offers up to 7% energy savings with no loss in lumen output. At $0.11/kW and 4000 hr of operation per year, the 7 to 13% savings translates to savings of $7.04 to $12.32 per fixture per year for a 4-lamp fixture. The 93% mean lumen rating of PENTRON® HO SuperSaver® lamps assures that light levels are maintained while energy is saved, over a very long life of up to 40000 hr (12 hr/start). For maximum system efficacy and performance, consider pairing PENTRON® HO SuperSaver® lamps with OSRAM QUICKTRONIC® QHE high efficiency electronic ballasts.
