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!
