How much heat does this give off? I currently use LED's because I cannot have any heat.

The light bar does heat up slightly. However it's never hot to the touch, just warm. I doubt highly that the lights would heat anything more than a few inches away. Hope that helps.

I have the MyStudio MS20 and haven't noticed any heat, and I've used it quite a bit for long periods.

I have had the LED light for several months now and it does not get hot, i.e. causing pain if touched. The low wattage creates very little heat.

LEDs can only be hooked up to a circuit one way. Make sure the longer lead (+) is hooked to the hot and shorter (-) is hooked to the ground. And you're probably burning out you LEDs. They're only rated for 3.2v, so if you're using a 12v supply without a resistor, you'll burn them up. You might get a bright flash as soon as you connect the power, but it won't work after that.

Can't honestly tell you the exact rating but being LED lighting there is no noticeable temp on the fixtures to cause any damage over time due to heat. I changed all lighting in my Motor home lights to LED and the drop in temp. will save the life if the covers and fixtures.

look for Buck Block at LED Supply. This big boy will supplement your 36volt supply to provide the constant current drive these LEDs need to stay happy. Be aware you will need a humongous heat-sink or forced air cooling to actually use this. And 8-9000 Lumens is a LOT of light. Most real life applications don't need that much light output. It's a fun toy though :) (Yeah, I bought one!)

I use LED bulbs in mine, which generate very little heat. If you used regular incandescent bulbs, the bulbs probably would get quite hot. There is a wattage limit on the lamp--- I think 60W/bulb maximum--- but, depending on what your lighting needs are, 180W total is probably more than most people would need, anyway.

We use energy saving bulbs so no complaints about any excess heat. Don't know about LED bulbs.

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

Yes, it doesn't require high heat, but you should use extreme cautious due to the mixture of led depending what you are melting

LEDs are 80-90% efficient (80-90% of the input energy is converted to light, the rest is heat). 20% of 10w is only 2w, which would not get an enclosed area very warm, so I question the worries over heating, but the manufacturer knows more than me. If you have 3+ light sin ana enclosure, I suppose the 3-6w or more of heat could warm up the air a bit. You coudl always give it a try and do a test. Run the lights for an hour and then quickly take apart the fixture/globe, turn the lights off, and finally feel how warm they are. Compare that test/temperature with another bulb running for an hour but not in an enclosed fixture.

I actually did replace one of mine with an LED just to test it out and almost no light comes out of it. The LED lights just don't seem to put out enough light. :( I would love to find some LEDs that do though considering I am running like 15 of these all night long.

The LED will actually perform better the colder it gets. But heat on the other hand can reduce the efficiency and lifespan or in some cases even burn out an LED lacking a proper heatsink.

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

They do not get hot only slightly warm. Easily handled with your bare hand. LED's do not generate heat. I asked one of my techies sons how that works and they said it is two metal plates, germanium and something else. when they apply current to one of the plates, it causes electons to jump to the other releasing energy in the form of light without heat. I love these bulbs, they are brighter and use about ten percent of the current than the bulbs I replaced. I plan to replace every incandescent bulb in my home.

I don't remember having an internal heat problem with them but I've swapped them all out for this LED bulb: Lighting EVER 10 Watt A19 LED Bulb, 60 Watt Incandescent Bulbs Replacement, 830lm, Samsung chip LED, Daylight White. This LED bulb offers the best trade off in price, wattage and amount of light in my opinion. But you have to be someone who likes Daylight White.

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.

Though I didn't actually measure the watts draw I would estimate they draw considerable less power than a normal bulb and puts out plenty of light and also very little heat. Led,s use so little power anyway, it's just a matter of just finding one that is a decent price while performing about as well as a standard incandescent bulb. Color, light output, price, and heat output, would be the most important things to look for.
