Hello All

I have a old 5ft Fluorescent light which was made in the 1940s

I am wishing to know if you can still buy the 5ft 80w Fluorescent tubes with
BC caps and the large 4 pin starter switches or do I need to replace the
starter swich socket with a modern type and the lampholders from BC type to
Bi pin type and use a 58 1 in dia or 65w 1 1/2 in dia tube

Regards

What's the designation of the lamp?

If it's a T17 type and you don't have more than a few fixtures, I wouldn't
bother looking for special lamps.

Modern type fluorescent systems are much more efficient and they don't need a
starter.

You can go for 75W F60T12/HO cool white or 55W F60T8/HO triphosphor. They're
both about 4,500 mean lumens.

The 75W T12 is brigher at first, but after you put about 8,000hrs on them, they
put about the same amount of output. The newer 55W T8 will maintain output much
better through the life.

Both types takes recessed double contact sockets.

I beg to differ. The 75WT12 is a single pin base, and much more readily
availible than the 55W.

Home depot has gone to these 55WT5HO lamps. They have been in the store
about two months. Already several ballast failures have occoured. Four of
the six lamps are out in 10 or more fixtures in only a couple of months. I
dont know about you but I think that is piss poor. If this is the future of
lighting, keep me in the reliable past.

Very tough to say the current disposition of bayonet replacement tubes, but
here's a little insight about them.
