do they run hot? (temperature)

The base is metal and serves as a heat sink, which does get hot to the touch. The plastic cover stays relatively cool. Otherwise it does not radiate heat the way a conventional incandescent or halogen does. They won't likely heat up your room.

No they are not hot to the touch.They also shut off when tipped to the side.

They have a class A amp with minimal ventilation, so they will definitely get warm/hot. Class D based monitors with this feature set will add another hundred or so to the price. I've left mine on for ~36 hours (weekends) in my garage a few times now - they definitely heat up but I haven't had any failures. I also gig with this, so overall I'd say they hold up pretty well.

I think so they do get extremely hot so you might have to hold them up a little. I've never tried it.

I hope they do, that is why I bought them. I just have not hooked them up yet. Since I don't have heat in the building I'm working on right now, they don't work in below 0 F temp.

Strictly UV, not a source of heat for the enclosure. They might get a little warm, but they are not to hot to touch or anything even when they have been running for hours.

They don't burn hot. They get hot like any other bulb sold out there. There isn't any torture on the wiring. I have had them for quite sometimes now. They've been great.

plenty hot. In fact, it is a bit difficult to hold them while trying to get the pin to hold.

Normally yes - they are only warm to the touch. But if you leave them on too long they can get hot to the touch. Good luck!

They're 'almost' warm. The color temp is 3000K. The usual temperature I associate with warm is 2700K. The usual temperature I associate with daylight is 5000K.

I am sure they get hot. I bought LED bulbs on amazon and they work well and stay cool and are dimmable.

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.

They do get hot. We have one in a cabinet that I do not put anything on top of but one on an open shelf that I do stack on, both work fine. I would avoid stacking components on one in a closed cabinet with no ventilation. I don't know how hot is "too hot" but they do fine used this way for us.

I have been using them for over a month now and I haven't had any problem. The spec says they should work up until about 149 degrees.

Yes, they turn on instantly. They aren't like the old ones that needed to warm up. As to the issue of temperature, I've never had a problem (and I live in Boston), but I don't use them outside. Hope this helps.

I haven't noticed that they have any sort of cooling effect. It may just be that they have better ventilation than other products, but for me I have found that I do get hot in them from time to time.
