here's a good one that has me stumped, about the above. bought a brand new fixture a couple of months ago,the rapid start type belive it's 20 watt ,two bulb. the problem is sometimes it comes on by itself sometimes not.i have changed ballasts, grounded it properly,& it still takes a notion not to work it doesn't.both ends of each bulb glow but want seem to start.but as soon as i touch the fixture it comes on.the bulbs are as close to the frame as possible.i had those $8 shoplights to work with only two wires before i got my shop wired. they never give a bit of a problem.even the ballast maker couldn't answer my problem.they even sent free replacements.but sometimes ya flip the switch & it comes right on.so i wonder what the problem coud be?
Agreed. I have solved this same problem by using another manufacturer's lamps. U tube fixtures are notorious for this. I have had good luck with GE bad luck with Phillips. Also, as said try to stay away from the energy saving reduced wattage low mercury ones. The full wattage energy hogs usually work best. Maybe the energy saving lamps save energy because they don't work half the time.
THANKS GUYS! i'll check on the bulbs.my parents are about to drive me nuts abot this. especially my mom!LOL!why would touching the fixture cause the to come on though?i'm lost on that one. but it seems to work every time.
hi ed, no paticular time involved. was down there tonight & it came right on twice. the third time it didn't. touched it ,then it came on. sometimes you would turn it off & it would come right on.i know flourescent lamps are tempature senstive.but this doesn't seem to be the case.all connections are ok too. i may try some different bulbs.then i may attach a wire to the fixture so they can touch it.LOL!
