do I need ventilation if I use led lights?

In order for plants to grow to their fullest potintial they need lots of ventulation. Plants need a fresh supply of carbon dioxide to turn into the oxygen we breath .

It says right on the neck of the fixture NOT FOR USE IN ENCLOSED LUMINARY. Many commentators stress how little heat comes from these bulbs. That is true on the lighted side. The backside or the side in the enclosed can is another matter. If you feel the backside cooling fins you'll soon realize that plenty of heat is generated, so much so that inside an enclosed can they'd be too hot to touch. That is undoubtedly the reason for the disclosure stated in the first sentence. What is at issue is the build up of heat. Will it trip the cutout? Will it affect the electronics that make the LED function? I have these same lights in enclosed cans in my house. For years I had halogen in the same cans. The cans are rated for insulation coverage. At the very least I'd expect a drop in life expectancy. It'd be nice to have a little vent in the can to vent the heat.

With LEDs you can't really translate lumens. I used the light with pretty good results. You want an open area, as to trap the heat released by the lights side exhaust. The light itself doesn't cause much heat, but the fan exhaust do!

LED's love the cold, however the low voltage power supply should be wrapped to prevent condensation. I have these in my cold display cases.

I suppose you could yes, but I would use a continuous light source that gives off little or no heat such as LED lights.

The diodes are very heat sensitive. Having the unit unventilated could shorten the life of the lamp.

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

One should be able to use LED lighting as long as the bulbs are DIMMABLE. Most LED bulbs are not. Dimmable LED's are usually more expensive . It should say right on the packaging whether they are or not . If you use non Dimmable LED's the lights will just turn on or off.

If I understand your question, yes. LEDs create light without creating heat. So no danger of overheating. The light seems to work well freeing your hands for various tasks. I think these LED head lamps are very useful.

No you'll need a standard light bulb. I would go with an LED bulb since Halogens give off more heat unless of course this is something you prefer.

LEDs generate very little heat compared to cfl or incandescent bulbs. If your can had either of these type of bulbs you should be okay. Insulated ceiling type cans are fairly standard in newer construction. Hope this helps

yes,..........you must change the bulbs for led. Because they will be very hot and can smell like wire that are burning.

I would assume that the issue is total load on the device (the internal wires are very small) and perhaps a heat concentration issue for incandescent bulbs. I would also think that LEDs would be OK.

These are LED lights and do not produce much heat at the lens (e.g. cool to the touch). Regarding the housing, I would ensure some minimum air circulation to dissipate heat vs. tightly enclosed, but there is very little heat output.

Im not sure if you can but they seem to be air tight. Very nice and bright LED light.

I would say no. The individual LEDs of the bulb are exposed to the elements.

I have LED bulbs in the fan now. I do not have them set up on a dimmer but that should not be a problem either.
