T5 fluorescent shop light fixtures =400 metal halide mh
4Bulb F54T5/HO High Output 6500K Daylight Fluorescent Commercial/Industrial Light with Mirror-Like Reflectors and Bulbs
T8/HO fluorescents offer 9% more design* lumens of light per watt than pulse start metal halide and 66% more than regular metal halide.
Includes 4 x 4' F54T5/HO High Output Tubes 4' Long
It's Used to replace to 400 w Metal Halide Fixtures
It uses 230 Less Watts! That s a $460 energy savings per fixture over the life of a set of T5 bulbs. (Assumes e=$.1/Kwhr and 20 Khr bulb life) Most often these are used to replace standard metal halide fixtures. The output of the bulbs is actually a little less, but due to the Perkinje effect, use of daylight tubes will make the fixture look brighter. Under the lower light levels found indoors, the brain uses both the rods and the cones of the eye. And the rods are much more sensitive to the higher energy blue wavelengths found in daylight.
