1) Rated average life is the length of operation (in hours) at which point an average of 50% of a large sample of lamps will still be operational and 50% will not.
2) Average life under specified test conditions with lamps turned off and restarted no more frequently than once every 3 operating hours. Lamp life is appreciably longer if lamps are started less frequently.
3) Average life under engineering data with lamps turned off and restarted once every 12 operating hours. Lamp life is appreciably longer if lamps are started less frequently.
4) Approximate initial lumens.The lamp lumen output is based upon lamp performance after 100 hours of operating life, when the output is measured during operation on a high frequency reference ballast under
standard laboratory conditions. For expected lamp lumen output, commercial ballast manufacturers can advise the appropriate ballast factor for each of their ballasts when they are informed of the designated lamp.The
ballast factor is a multiplier applied to the designated lamp lumen output.
5) Design lumens are the approximate lamp lumen output at 40% of the lamp’s rated average life.This output is based upon measurements obtained during lamp operation on a reference ballast
under standard laboratory conditions.
Lamp meets US Federal Minimum Efficiency Standards.
