Does this bulb function at very low temperatures? I want to use it in an unheated garage.

This bulb works very well at low temperatures. I have it in several outdoor fixtures and it worked well this past winter in Cleveland, Ohio. We had lows around -12 degrees without any issue. I will warn you however that the bulb does not like higher temperatures, the internal cooling fan cannot keep up with the heat the lamp produces. I have had to remove 12 of these from an office building because they were overheating and melting the cooling fans. This is a great bulb, they just need to perfect the cooling. The output of this lamp is greater than that of a 175w metal halide lamp.

dont waste your money! a 75 watt incandescent bulb puts out more light than this bulb.

In side a garage should be fine most likely, i installed mine in the spring so mine has only gone through maybe mid 20's so far, didn't have it yet when it was -25.In reference above my bulb is outside as a street lamp above the garage, so the mid or high 20's its felt so far was full force

Hi Scott. I don't know from experience yet, but I'm in the same boat as you. I live in Ohio & have this bulb in my unheated garage. I read at least one review somewhere that said low temperature is not a problem & basically I'm hoping that review was correct. Btw, I'm very happy with this bulb so far despite the high price. I considered putting in fluorescent lighting but don't need to now with how much light this puts out. Good luck! Jerry

It has worked well in temps below 50 f. I have not run it any colder yet but I feel it should have no problems. It starts instantly.

yes, it will work . the bulb can be used in both outdoor and indoor setting as long as its in a full or semi closed enclosurecheers

I have them in my garage here in south Texas. As per instructions no ballast is required. It rarely gets below 25 degrees here. I do not see why they would not work since they are led. They have no issues in the South Texas heat. Not sure if I really answered the question but I tried. :-)

I'm sorry I can't say what the temperature rating is. But I can say I am using a few in a cold envirnoment and they have been fine. I have a smaller 4w LED in a an outdoor lamp on the side of the garage. Here in N. Illinois we have had about 20 nights near or below 0 and the bulb works fine. I know most cfl's cant handle extreme cold, never heard about LED's. good question.

don't know but used in unheated garage and was below 0 a couple of weeks ago and worked fine.

If the temp is below 50 degrees, this thing will warm the garage slightly...however, it will not work well in a colder garage.

I think it would work fine in a small garage-if your intention is to set it low to keep pipes from freezing, if you intend to heat the garage in a cold area it would probably run constantly. pretty simple design, the only issue I had was to replace the fan motor as it had worn out after a couple years of use.

This bulb is a direct replacement for an incandescent version and the color is very comparable. I have not used outside but would imagine it would work just fine as long as it is in an enclosure as all the LEDs are Surface Mount Technology. So using the same enclosure of the original lighting would be fine...and there is no heat from these replacements as in a normal high output bulb. Hope this answers the question.

I live in Texas so heating is not an issue. On cool nights here I use a lightbulb and this is enough to keep it warm. You should be able to figure something out. I Hang my bulb from a heat lamp by a metal clip from the center frame. I would not say this greenhouse is the most airtight thing out there.

Hi I think it would work the bulb gives off little heat. But check to make sure it would fit in the fixture your planning to use

This fixture is only designed for fixed installations. It is a halogen bulb and consequently runs very hot. I have put it on an occupancy switch to insure it turns off when not in use. If you use a separate power cord, I would recommend insulation rated at at least 140 degrees C.

Yes. This fan is rated for direct contact with insulation. Being a fluorescent bulb, it does not generate very much heat...

Anthony, I'm a bit slow on installing these, I bought 8 fixtures last year and another 2 recently. T8 fixtures are supposed to work well in low temperatures (20 F) so I'm trusting the liturature I read and what I've heard from coworkers enought to buy 10 of these fixtures. Sorry I don't yet have first hand experience.

Mine are fluorescent lights so "Yes", but...a couple times I have had to manually flip the switch on the lights off and on again when first activated in a cold state. Not severe for me, but it has happened a couple of times. So, I'd say "yes, but...better inside than in a cold garage.George's comment below seems to encompass the best answer so far, where instant start bulbs are the way to go, not slower tube, if possible.

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.

Dear Michiganian,I tested the bulb and touched it while it was on. Didn't know or care before. You can touch the plastic part where the light shines through, no problem as it is only warm. The metal part in the middle of the bulb does get a little hotter though, I would say hotter than warm, but not really hot. I can still touch it. Hope that answers your question.

It should work, if worry about heat transfer if the bulb is to close unless it led or cfl.
