Does look like 800 OCV! That should be a good fryer! It is interesting that the T12 electronic ballasts do not seem to have EOL protection like a lot of T8 ballasts do now.

well EOL protection seems pointless on T12, they don't get cracked ends or cause hazards

i still prefer T8 ballasts EOL protection free .. its so much more interesting

@Alights Yep 800 OVC I'll have to try frying a EOL lamp with this one LOL

@DieselNut I don't know if this one has EOL protection I do have one (if i remember right Advance) that does have it.

@Powell Thats true! I've had T12's crack @ EOL before.

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

How does This perform in cold temps with F40T12 lamps? Its either between this or the Howard industries ballast for my friends garage since lamps won't start reliably yet are grounded and everything

I've never tested it in cold so don't know.


If I can find it I can maybe test...depends on how cold?
We got alittle snow this evening & its supposed to be a bit colder the next couple days (but not really bitter cold)

i have compared the specs and the Howard is about $2 cheaper a ballast and has a 5 year warranty versus the universal basic 12 is only 3 year warranty
the howard industries ballast says 32F minimum starting temp, but it has 600 OCV and reviews were pretty good so i have decided on it, really the lights only have to work down to 0F

Howard probably should be a good choice then .. it'll likely start just fine below its "32F minimum" anyway

I dug this up & might give it a 'cold test' sometime LOL

I have a Howard Industries electronic rapid start ballast. I got it from a friend, thinking it was just another piece of cheapass chinese junk, but I have fried tube after tube, back to back on that thing and it will run em to vacuum loss quicker than anything other than a 400 wat MH ballast! It is a trooper! Howard's magnetic ballasts are JUNK though. Very high failure rate, in what I have seen.

Frying EOL lamps is fun...
I think the best ever lamp frying I did was a couple years ago when it was below zero(f) outside...

400w SON gear is the best for frying old lamps:)

I have the one-lamp version of this same ballast and have finished off several F40's on it - they put on a great show and eventually lose vacuum. And yes, this ballast starts cold lamps instantly below 0 Fahrenheit with no problems. The lamps will have striations though and be dim in the centre.

I use my Basic 12 for testing lamps and giving them their second life (after they won't light on a magnetic ballast anymore, they easily go for several more hours on this). I've tested every length of lamp from F4T5 to F40T8 on it.

I'm lampin...

@arcblue: one of those 1-lamp'ers might be a good candidate for... freezing cold night lamp finish off'er

@FrontSideBus: that would be fun to see LOL most I've ever used is a VHO ballast

installed one of these in my buddy's garage, it instant starts the sylvania F40T12/ design 50 lamps even in 20F weather (1000 OCV), the 10Howard industries ballasts all do a 0-2 second rapid start start up, but seem to work well in the cold!(600 OCV) also have a GE proline T12 electronic ballast installed and a Motorola T8 parallel RS in use with phllips Alto 850 lamps as a test

I've been waiting for a real good cold night (atleast zero(F) .. 20F isn't really cold ) to test a few electronic RS ballasts
Now that its into march, I don't expect any of that weather (but LOL I hate cold anyway)
