This LED fixture is 33.25" long, 2 3/4" shorter than the 36" fluorescent fixture, has a low profile lens, and the body has an otherwise identical appearance with the same 2.5" width. The lens is low profile, meaning the fixture has only a 1.25" height, which makes it ideal for under-shelf use as well as overhead lighting. Sleek modern look.
There are 72 LEDs in this fixture. The LED output is a maximum of 2400 lumens at 12 volts (fluorescent version is only 850 lumens). LED amp draw is 0.40 to 1.25 amps (fluorescent version amp draw is 1.1 amps). Operates on 8 to 30 volts DC, perfect for your 12 volt Tool Truck system. 3 year warranty. On/off switch. Made in the USA.
Note: there is a slightly longer 36" long body version of this light fixture available for additional cost, but it has the same number of LEDs as this fixture, 72, so the light output is identical. Why pay more for cosmetics?
