how much heat does the bulb generate during operation?

Not much at all, warm to the touch but not hot. Significantly less than cfl and standard bulbs. Mine are less than a foot away from my lettuce and no scorching.

It is never too hot to touch the metal desklamp shade I have above it. It gets very warm but not hot. I would say less than or about the same as a 40 watt bulb.

It gets a little warm, but it's nothing too bad. I had no worries leaving it unattended in close quarters for hours at a time.

Let me start out saying you bought the right light its awesome quality and durability. As for heat no this light produces minimal heat. You can hold the bulb. When its on that is how minimal it is

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.

If I needed a light to always be on I would get one with an LED bulb. I have never noticed this light getting hot. I use a 20 watt bulb in mine, so its on the low side of energy usage, compared to incandescent bulbs.

Any heat created from this bulb is very small. I have a second heat lamp to supply heat for my bearded dragon.

Depends on how long you leave it on, and type of bulb that you put in it. I use LED bulbs, which only need 1/10th of the amount of energy that incandescent bulbs.

Yes. LED bulbs produce very little heat and that is why the are so energy efficient.

I dont know about the particular details, but I use it for a few hours so its not worth switching out a bulb for that time.

It's not a question of total watts of heat. It's more an issue of how much heat in how small an area, the area being the bulb base with the electronics inside. There are flammable items in there if overheated. However, high heat will, as others have pointed out, cause the electronics to passively fail (i.e., fail before fire). It would be best not to use bulbs in a full enclosed fixture if the manufacture warns against such use. Btw, LEDs are more like about 35% energy efficient. You need a Mercury Quartz lamp (one of those awful looking parking lot types) to get up around 80% efficiency. A recessed fixture would be fine, but enclosed, not so good.

Don't see why it wouldn't. There is no heat generation. Works just like a regular bulb but doesn't burn out. It just keeps going & going & going. It's the Energizer bunny of bulbs.

Because it uses LED and not a conventional incandescent bulb, you won't feel any heat. However, I don't know how efficient this lamp is and how leaving it on for hours and hours at a time will affect the longevity of this lamp.

the light may be more intense than you need for a range hood -- main thing I would consider would be the heat given off by this bulb, which is substantial

I don't have the equipment to test for that but if there is any electricity used when the bulb is off it would be mininmal. The bulb uses very little electricity when it is on.

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 is not going to get any brighter and a larger watt bulb will generate too much heat. The lens is opaque and limits the brightness of the light. Replace the dark plastic lens with a cut piece from Home Depot that allows more light to pass through.

I'm not sure I understand your question, are you talking about the energy used or the amount of light produced.The package says the bulb consumes 60w of energy but puts out nearly 250w. I have two of these and I can say they are very bright.

I haven't had a problem with heat. The CFL bulbs never get too hot. I've used mine for hours at a time with no problem.
