Do these generate much heat? I am looking for something to put in my garden when there is a rare frost here.

It does generate heat but I don't think a sufficient amount to prevent frost damage. It would need to be isolated to a very small area at a close range which could in itself cause damage to plants.

I've found that it does not produce much heat at all. Mine is on an open deck so the heat rises into the air. It might feel warmer if placed under some type of covered area which would trap the heat nearer the ground, it is a beautiful affect but not warming.

I live in Alaska, no problems in NEGATIVE 20 degree weather, we just lit them and kept them setting near the ground till they filled up. Then off they went

I have used them for frost protection, and they have worked well. Except last year was an exceptionally heavy frost and they did not save the plants. Since i live in Southern California, that was probably a mild frost by MA standards!

I must have gotten a defective model..Not much heat coming from mine..my tomatoes all were frost killed..also the wind blew it over even though we put heavy sandbags on the bave as per instructions

In my experience, these relays generate a lot of heat. I added a fan to my application to keep them cool.

Yes, indeed! They DO GET hot! Don't touch. But they don't emit heat like incandescent bulbs do: ie they are cooler in that regard.

Just planted mine in Virginia and so far they have survived 2 frosts. Although I did cover them, but 3 weeks in the ground, so far so good.

Yes, they do get hot, but maybe it is because I have a gas range. We do have to use pot holders.

I've only used them indoors in my fireplace. And they heat up the room nicely with no Cleanup! Outside, they might not do as well in the wind without some kind of metal backdrop to protect from the wind. (Just guessing)

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.

YES! I use these as my primary heat sourse. I live in Dallas so the winters aren't like up north. They do a good job. As a primary hear source I feel the need to air out my house on warm days as they burn room oxygen.

No, there is very little heat generated from this light unit. I use it to illuminate a refugium which is in a cabinet and I don't have any problems with heat at all.

I would like to use these to experiment generating electricity. What temperatures do they handle? Thank you

It does give off some heat but not too much. We use 4 at a time on 4 layers with a cover and the seedlings were comfortably warm in the winter.

I use them outside a lot, but only for a couple days at a time. They get quite hot and are not designed to be used outside for extended periods. Keep a close eye on them and don't let them come into contact with anything that melts or might catch fire. Good luck.

I don't notice any heat output from mine; however I put LED bulbs in the fixtures, and these don't produce much heat anyway. LEDs are much more expensive, but last about three times as long as halogen bulbs. It you use halogen bulbs, I think a lot would depend on your ceiling height.
