What is the low temperature rating on the ballast?
247937
Not sure of the rating but ours were installed 4yrs ago and this winter when we dipped down to 8 degrees (32 in the building) they went out. One didn't come back and I'm replacing it.

Note sure exactly, but I had no problem so far. Just a suggestion, tho. I'd really recommend that you use these fluorescent tubes. It worked best for me in terms of lighting (that is, if you want your light to be bright but also very pleasing for the eyes) and this bulb, specifically, is really durable and energy efficient. Hope it helps! (Case of 10) F32T8/SPX65 DAYLIGHT Linear Fluorescent 32-Watt T8 FO32 865 Light Bulbs 48"

Not sure of actual temp rating, but I will say that it lights up no problem in my garage with temps below freezing in the garage.

These lights have held up excellently for me in my garage with temperatures dropping down to around zero.

Mine turns on just fine with no flickering, but mine is in our heated house. Typically the flickering is caused from using a fluorescent type fixture in a lower air temperature (below 35-40). The ballasts on most of these you find in HD or Lowes aren't made to work in lower temperatures and they will flicker until they warm up.

Terry, this. Ballast works perfectly with two tubes of 40 W, it is also very cheap.

We currently only have the ones in the first photo (with multiple notches), however, both ballasts are functionally identical. The one with multiple notices has better cooling capabilities because those notches are heatsink fins intended to cool off the MOSFETs inside the ballast. Hope this helps!

ballast is bypassed, would not work. I'd suggest labels for hot and neutral too.

Don't recommend digital ballast for this lamp as it gets extremely hot that's my opinion good luck

i have it @ 7 Celsius , and is working fine so far. i think you can still go lower. hope this helps.

Dear buyer: Thanks for asking . 55W AC ballast will brighter than 35W ballast. And 55W quality, stability are better. Thank you Sean

Sounds like either the bulb or the ballast is going bad. More then likely its the ballast, but double check all your connections and make sure you use some dielectric grease on the connections. After that you could try switching either the ballast or the bulb to the opposite side and see if you still have the same problem. The problem should follow which ever part is bad.

the ballast has to be HPS and wattage compatible. if you can afford it, the best is the dual arc 1000w

The warm up is not long... and the ballast are way better than my old zentec kit... so far still working and I dont get any flicker

The bulb does not care what the ballast runs on. You need to search for a ballast which accepts 220-240v. Good luck!

Yes ,i did it just worked fine. my ballast is for 600Wthe bulb works in 100% 75% and 50%!

T8 has lower lamp current than T12, so what happens is T8 on a T12 ballast overpowers the lamps. So they will run at say 36w and shorter life.

Not sure of the exact temp. But it's pretty darn close to all fluorescent lighting

46F is the lowest setting. use it as lager beer fermenter so around 50F is sufficient for me.

The warm up is seconds & they will be as bright as your bulbs allow. They are good durable ballasts.
