Time to upgrade the lighting. I need to learn all about what is available now -especially, it seems, LEDs. 50x50 hangar with zero heating, 14' ceiling (uninsulated metal, occasional roof drips), 120V readily available on two dedicated 20A circuits. Mission is 'blazing bright', 5000K is acceptable here, will put in as many as needed to minimize shadows. Current lighting is 8 metal halide bulbs with no reflectors or shielding Tell me: -what you like and why -longevity of bulbs (ballasts?) and other hardware - very important; will pay more to avoid going up ladders -best cost per lumen -ease of install -needs to work well in m10 to 30C weather -must come on within 2-3 minutes -oh, my hangar has voltage variations up to 15v from nominal thanks to our stupid electric co (one day I will tell you about running power tools at night, and the metal halide lights go out as soon as the compressor kicks on; mind your #!& fingers) -I won't say no cost limit but I am willing to fork out for this project. Unreasonable to think I can do this for <$500? -links to other threads welcome. But don't let that stop you from posting here.
