I had a bunch of flourescent lights with the tubes went bad in my garage. Some are 48" long ones and some are the U shaped tubes. Since I had seven sets of lights I have been lazy and waited till now to replace them after about six of the tubes burned out and 2 that are immiment (doing the flickering thing and if I turn it off and back on again it will come up).
Now I bought 10 new tubes and replaced them. But out of eight tubes only two came on the other six remain dead. It is a little tricky to get them in and I had to push and twist them into place. I tried removing them and reseating them again, no luck.
I must be doing something wrong? Are these tubes polarized? or can it either end go in either socket? Even the U shaped tubes do not lit up and there were working fine (flickering) before I installed the new ones. I was pretty careful when I removed them so I don't think it is likely that I damaged the sockets when I removed the old tubes.
Any idea?
Thanks in advance.
