1) Rated average life is the length of operation (in hour s) at which point an average of 50% of a large sample of lamps will still be oper ational and 50% will not.
2) Average life under specified test conditions with lamps turned off and restar ted no more frequently than once every 3 operating hour s.
Lamp life is appreciably longer if lamps are started less frequently.
3) Average life under engineering data with lamps turned off and restar ted once ever y 12 operating hours.
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 reference ballast under
standard laborator y conditions.
5) For expected lamp lumen output, commercial ballast manuufacturers can advise the appropr iate 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.
6) 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 laborator y conditions.
