Westinghouse F40T10 CW/99

Westinghouse F40T10 CW/99


A Westinghouse "Extended Service" F40 T10 Cool White lamp...
The 'Extended Service' seemes to be true, these last a long time :) Black endcaps as well!

Being a T10 these are kind of an oddball lamp & cool at the same time.

Dimmer than a standard T12 CW (particularly on a LPF RS ballast)

Came out of an old 3-lamp fixture i got at a flea market (i'm guessing atleast 15 years ago)

3 lamp fixture? Do you still have the fixture? I have several of these lamps too, but they are brighter than a F40T12 when used preheat or on a full power RS ballast.

Preheat Fluorescents forever!

I've always used these lamps on a LPF ballast because of the fact they are dimmer LOL (might have to try one on a full power RS sometime though)

For the fixture... I'd gotten 3 of them as a lot cheap at the flea market (good thing they were cheap because they were 277v - something i didn't think to check for at the time). 2 got converted to 2-lamp / 120v and used. The third got converted at some later time and just kinda sat around...its currently in the crawlspace full of junk LOL.
I'd eventually planned to do a video just because the thing is such a thick-metal heavy beast & junker-ballested... (nothing like some of those paper-thin shoplights sold these days) LOL

Colored Fluorescent's such as F40T12 Red or  Green or Blue are awesome...

Did it have one three lamp ballast in it? You can run 277V fixtures on 240V. I have a friend who has had several running that way for years and they work flawlessly! I have run several on 240V and even with the "energy saver" ballasts, they will light a full power F40 at nearly full brightness.

It had a 2-lamp + a 1-lamp. I actually did try running them on 240v soon after getting. The 2-lamp wouldn't light, the 1-lamp did light full brightness but overheated & died after a couple hours...i got rid of the rest of the 277v ballasts (wish i woulda known about date-codes being on the back of ballasts back then LOL just to see how old that thing was).
