did some rewiring and installed new lighting fixtures in my shop, I replaced 6 eight foot florescent lights with 6 LED lights, while I was doing the fixture rewire for the LEDs, I decided to split the wiring in the fixtures to make one bulb in each fixture on a separate switch, this would give me a good even light across the front of both bays, but also able to crank up the light when it was needed,(same principle as a dimmer)the results were amazing, good bright light when you need it, once you get over the sticker shock, its the way to go!
