High ballast factor
WebFederal purchases must meet or exceed the minimum efficiency requirements in Table 1. These requirements are stated in ballast luminous efficiency (BLE), which is the ratio of total lamp arc power (TLAP) to ballast input power. A higher value indicates a more efficient product. Table 1. Efficiency Requirements for Fluorescent Ballasts. Lamp Type. WebAn ANSI ballast for standard 40-watt F40T12 lamps requires a ballast factor of 0.95; the same ballast has a ballast factor of 0.87 for 34-watt energy saving F40T12 lamps. …

WebFor locations where you need additional light, such as areas with high ceilings, choose high ballast factor (above 1.0) programmed start ballasts. You can choose to operate your T8 lamps at a higher wattage to increase the light output by up to 10%. Not sure which of these programmed start ballasts to use with your lamps?
WebHowever, if it is known that a percentage of the lamps are burnouts at any given time, then a light loss factor must be reckoned with. For example, if 5% of the lamps are burnouts at any given time, then this light loss factor would be 0.95. Remember that 100% rated life is defined when 50% of the lamps in a large sample of lamps have failed.
