Interesting that it is rated for 0 deg.

Keep government out of the lighting industry.

T12/ t17 there's a reason they made heavy magnetic ballasts

Wire em up on 240v. It will work nearly as well, only slightly underdriven.

Preheat Fluorescents forever!
I love diesel engines, rural/farm life and vintage lighting!

I've got a 120v, brown/white label version of this. Despite dating to 1984, it still only lists 40 watt lamps, though the installation it came out of was full of 34 watt lamps, but being spot-re-lamped with 40 watt lamps, some of them by me. It was removed on mistake of being thought to be bad, but when the new ballast didn't work right it became obvious other things were at fault, so I ended up with it, pays to make friends with the maintenance people, I had him always leave the wires on removed ballasts as long as possible. Took it home and it worked. So now it lives in a 1970s Sears 2X40 shop light. Not as bright as a true .80a I wouldn't say, at .65a line current, and is a little more cold natured, but otherwise starts and runs and warms up cold lamps like a .80a ballast. Was nice to get a proper ballast back in that particular shop light fixture, it had had its original HPF full power ballast replaced with a junky residential low power factor one at some point...now it's HPF once more and runs a pair of Norelco F40CW lamps, era appropriate!

Ive also got the 120volt brown/white versions of these, thanks to Don93s for sending me links to them. Normally with the 0 degree
rapid start ballasts, lamps seem a little bit dimmer than regular .80amp ones but the universal ones I got seem to run
lamps a lot like the regular .80amp ballasts. Noticeably brighter than the Valmont Bonus line ones from what I can tell.
The universal ones I have are also noticeably loud. Nice buzz and hum to them.

Interests
1. Motorcycles, Women, and Lighting (especially fluorescent)
2. Weighting/staying extremely athletic
3. Severe Thunderstorms of all kinds
4. Food and drinks. So gimme them bbq ribs
Yep
Lighting has been a passion of mine since I was born. I consider everyone on LG to be a friend

I have 120v 0 deg versions from Universal, Advance, and GE/PowerProducts and they all are slightly dimmer than regular .80a ballasts. I think mine averaged around 330ma with 2x40w lamps. With 30w lamps, the current slightly higher. The EOL is more flickery though especially 30wT12's.
