When used with the UltraStart programme-start ballast in settings such as office and industrial buildings, warehouses, retail chains, schools, hospitals and government buildings, the GE F28T8 lamp can deliver a 15% reduction in wattage compared with a standard three-lamp F32T8 system. It also offers a 24,000-hour rated life at 12 hours per start, 2,750 initial lumens and a colour-rendering index (CRI) of 85.
The F32T8/XL/WM lamp works with UltraStart programme start ballasts to deliver a 6% reduction in wattage compared with a standard three-lamp F32T8 system. The F32T8/XL/WM offers a 29,000-hour life at 12 hours per start, 2,800 initial lumens and a CRI of 84.
The F32T8/XL/HL offers 10 percent more initial lumens than the standard T8 (3,100 vs. 2,800) and up to a 29,000-hour life at 12 hours per start. Energy savings can be achieved by using three F32T8 High Lumen lamps instead of four standard F32T8 lamps.
