Can this bulb be used in cold shop...like below freezing temps?

yes, thats where I us it. I have a uninsulated garage for my shop and I live in the mountains of colorado. they take a few minutes to get to their full brightness but I have had no problems with them.

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. I use mine on our front porch. It comes on instantly and shows no sign of dimming in the cold. I love LED bulbs.

Higher operating temperatures may shorten the life of an LED but I don't think it's something to be worried about. Colder temps should have no effect on it.

You can if you like, but it's not necessary. I left my lights outside all winter (in Detroit, MI): the coldest and snowiest on record for the past 120 years! They worked beautifully all winter long (except perhaps when they were covered with snow.) They still worked like brand new as soon as the snow melted and they could recharge in the sun again! If anything, the "glass" is a smidge cloudier than when they were brand new straight out of the box (and after a whole year of use), but they still look good and give off good light. Best solar fixtures I've ever purchased. I'm very happy with them.

put two replacement bulbs in a couple of weeks ago and too early for me to say if they will frost. I am not using currently except to do maintenance work and restoration. Sorry I can not give you the answer you are looking for - Ron

They are not bad. I have had some 13 watts bulbs come on faster.. but it is not like it takes a minute before you see bright light.I do not know on cold weather. I have not tried these outside. I usually leave my outside cfl on 24/7 in cold weather, because they die out more quickly if you turn them off and on all the time in the cold.

I get frustrated because retrictions on bulbs vary by brand and model and they don't always advertise the restrictions until you open the package and read the fine print. Here are the fine print restrictions shown on the 'inside' packaging of the Cree 18-watt (100 watt equiv) bulb: Do NOT use in enclosed fixtures. Allowed temperature range: -13F to +113 degrees F. Suitable for damp locations but NOT where exposed directly to weather or water. Not intended for use with emergency exit fixtures or emergency lighting. My words: (You might find the 60 watt allows enclosed fixture use but not the 100 watt)

Mine is in our garage, but it is open to the south. I think if you had some kind of 'lamp', the bulb would be fine outside.

Yes, I use in the garage. I like LED instead of CFL for cold places. LED's don't have a warm-up time.

I'm not am expert, but I don't see why not. Especially if it will be enclosed. Led lights are not affected by temperature swings like CFL bulbs.

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.

They are rated for -40c if you look at there specifications , most LED fixture like the cold better than excessive heat.

Yes i been useing cfls in one of mine for about a year, but in cold weather it takes a few minutes to warm up to full brightness, i could not stand using cfls in the house so i am using them in my heath/zenith.

I don't see why not unless there are extreme temperatures. The main limitation will be the bulb's distance from the transmitter module.

Hi Alan,I don't know. We never have cold weather here. It works fine in our shop, which seldom gets below 60 degrees.

This is primarily frost protection. It may hold a little residual heat in, but additional protection for freezing is needed. Some people put an electric light under the cover and the heat from the bulb trapped under the cover will protect from freezing weather to some degree.
