6 lamps out in a row I have a UltrSun UltraBurst 4000 and the first 6 bulbs back of the bed and 6 first bulbs front of canopy are out..Each bulb has its own ballast . I could hear a crackling/electrical sound when starting it. Not sure if there are some wires burtout or something thats causing them to burn out?..
Any ideas?
Thanks |
