Will test LED bulbs work in a low temperature environment? I'm looking to eliminate ballasts because they don't work in my unheated barn.

Lori these light work great in all temperatures, I am very pleased with mine in my shop. They come on immediately in 20 degree weather unlike my other florescent bulbs.

Yes it do work even i can tell you i put 400 of this bulb and only two burn in three years

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. :-)

Most manufacturers' published ratings of LEDs are for an operating temperature of 25 °C.

I have 4 in a garage that on occasion gets down around 40 in the winter and they seem to be fine so far.

I purchased Cree LED light bulbs at Home Depot which seemed to solve the problem. Apparently these bulbs are more efficient (lumens per watt), which implies to me less heat is being generated. These bulbs are also cast a more diffused light that other LED bulbs. Note that LED can lights are designed for the can enclosure, which is not true for LED light bulbs. Someone mentioned dimmers not working. I have found out that the dimmer needs to specify that it will work with LED lights to work properly.

I am not an electrician, but I believe that ballast is only needed for fluorescent lights and would not be needed for LED bulbs.

LED bulbs should have no problems working down to 0F (-18C). As to the higher temperature, 100F (38C) is not a big deal for any consumer-grade products. Plus you probably won't use the light during a hot sunny day, anyway.

I don't see why they wouldn't work. There LEDs so they run cooler than regular bulbs.

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.

I haven't seen any problems with the Cree LED bulbs. I have them in my office, and the lights are turned on and off frequently. They illuminate instantly, and are not subject to problems with poor illumination in cold environments like CFL bulbs. Also, CFL bulbs don't last nearly as long as advertised. My fixtures are hard to reach, so the longer life of LED bulbs is a definite plus.

I am having no problems with my led bulbs. I have been told that some of the less expensive dimmers don't work with led bulbs.

I called manufacturer with same question. LED lights (and CFL's) have built in ballast which do generate some heat, but not enough to be dangerously hot. However, enclosed LED life is reduced due to the heat that cannot be dissipated. For maximum life results, it is not recommended for enclosed appications. In my application even if life is reduced by 1/2, it is still cost effective vs incandescent bulbs due to change out cost. I have had these bulbs enclosed for over a year in bathroom application with great success so far. The instant full bright feature is hands down better than CFL's. Even at 0 Degrees F on patio in winter, it is full bright instantly. I'm very happy. I called manufacturer with same question.

That is the great thing about LED bulbs, they us much less electricity and do not generate any heat! The answer is yes you can.

Good day, I purchased some of this model LED tube from this particular company and the tubes work well. Realize that LED fixtures are NOT compatible with fluorescent ballasts, so you cannot plug them directly into a pre-existing fixture. The ballast must be removed or you may "hot wire" them around the ballast. Different manufacturers wire differently. There are four prongs: two on each end. You only need two of those prongs. Either the two on one end or the same two on opposite ends. I am currently on the road, so I cannot look at this particular tube to tell you how to wire it, but if you say you have "hot-wired" and it works, you have picked the correct wiring configuration. Yes, it is wired directly, no ballast. That's the way LEDs work. Hopefully this message has been some help or, at least, reassures you. Good luck. Bob

I used that bulb in a digital and a magnetic 1000 watt ballasts worked fine but only lasted 6 months and no warranty. I replaced it with one from a local grow store with a year warranty for $60 and don't have to mess with damaged bulbs in shipping and the wait.

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.

Jamster,I have yet to see a led bulb with minimum operating temp less than -22 F. There may be a handful under that but I wouldn't expect it. Only question is how the bulb will respond....will it not work properly during extreme cold or will it kill the bulb...I don't know. If I were you I would buy a cheap led bulb to test it out.

I'm assuming you tried these in another socket eliminating the lights or fixture. I have 4 installed with a dimmer. Temps have been in the 20's and they work perfectly.

Hello! I have to try to use LED bulbs.. but did not worked! Burned LED soon as I've installed... You must use with halogen bulbs.If you looking for LED.. do not buy this product! Thanks!

I don't see why that would be a problem. They aren't like florescent bulbs that need to stay warm or take forever to warm up if they're cold. LED's don't care much about ambient temperature.
