well, about to remove all the real work out of the booth and put a car inside. Noticed 2 bad ballasts. Here we go again. Why not make the switch now. So after bouncing around a few sites, I stumble upon batteries and bulbs. Never thought much of them, looked at batteries for an electric chair there once. I do not think I got the right bulb, but this LED11665 say 28-32 watt replacement, smaller diameter than the 40W I am removing. Wiring was strange, black and white wire are on one side of the lamp, the opposite side just needs a socket as a holder, no wiring. 5000K, Daylight, 1800 lumen, 50,000 hour life expectancy. Frosted cover which is actually glass. Did the sides first since they are a pain to pull out, turn, pull the center off to a bench, just went sides on and was not too impressed, but when the 24 bulbs on top of the booth lit up it was as bright as it has ever been.
Either way, sign up as a business and get a buck off per bulb, paid 5.90 each. Trashing some sockets cost me more. They had them for 1.35, but only had 17 in stock, and of course we had to paint the inside of the fixture while they were apart, put a polyurethane on them this time so that epoxy wont just turn yellow again, but swapped cracked sockets, 48 bulbs, got it done for about 400.00. I figured it would have cost a grand easy. So if you are looking, just a suggestion.
