Replacing T12 Flourescent Lamps.

Posted by g-mann (My Page) on

My shop light has T12 25W lamps that need replacing. They are the originals, and in fact made by G.E. and say "Utility Shop Lamp" on the end. My problem is that I cannot find T12 in 25W. The only thing I can find are T12 40W.

I need to know before I buy. Will the T12 40W work as replacements for the T12 25W?

No.

Why not change out to t8? The t12 lamps have been discontinued for a while now.

These are 4' lamps? David provided good advice. T8 is much better than T12, from by cold start, flicker, brightness maintenance,.... If you are any good at all with wiring and the light is quality, replace the ballast and put in new lamps. If the light is junk, go buy something else.

If the light goes on and stays on for long periods, an instant start ballast is best. If you turn it on and off a lot, rapid start/program start will be better because the lamps last a lot longer. If you don't use the light much at all, don't worry about it. Pay attention to the wiring or the original ballast because changing types will mean changing the sockets.

A Google search shows T12 25 watt lamps being available. Price with shipping added is steep.

Here is a link that might be useful: Lamps

T12 lamp fixtures are no longer sold (i don't think), but replacement bulbs are still available. But yeah, I'd replace the ballast with one designed for T8 tubes because they're more efficient, available in a wider variety, and the electronic T8 ballasts don't hum.
