*Rated average life under specified test conditions with lamps turned off and restarted no more frequently than once every 3 operating hours. Rating based on Program Start ballast for T5/T5HO, Instant Start for T8 and Rapid Start for TT5 lamps.
Application Notes
Results based on: Average footcandles maintained, total Light Loss Factor (L.L.F.)=0.82 Reflectances: 80% Ceiling (white acoustical tile), 50% Wall
at 2950 lumens, RE835 TT5 lamps rated at 3150 lumens, RE835 T5 lamps rated at 2600 lumens & RE835 T5HO lamps rated at 4500 lumens. 1' x 1' calculation grid at 30" from finished floor.
Results may vary.
Calculations have been performed according to IESNA & CIE standards and good practice. Some differences between measured values and calculated results may occur due to tolerances in calculation methods, testing procedures, component performance, measurement techniques and field conditions such as voltage and temperature variations. Input data used to generate the attached calculations such as room dimensions, reflectances, furniture and architectural elements significantly affect the lighting calculations. If the real environment conditions do not match
the input data, differences will occur between measured values and calculated values.
