How much heat does the fixture itself produce? I'm not worried about burning plants, but would like to mount it to the underneath of a sturdy set of plastic shelves to make a grow tower for seedlings. Is it too hot to mount very close or possibly...

Its not very hot. I mounted mine directly under a cheap ikea table with no issues at one point.

I would be very careful using a space heater in a possibly wet area and keep in mind, this is PLASTIC. Not wood or metal. I would exercise caution regardless of what you use. A small, stable space heater would keep it plenty warm for your plants. You don't want it too hot. We didn't use a heater at all and our plants made it through many days of 20-30 degrees.

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.

I have never noticed the temp to be hot. It is occasionally warm up at the top near the bulb, but the stem in not even warm. Hope this helps.

The heat they put out is so minimal, plants can nearly touch the bulbs and not be cooked. I have both two bulb units and one of these. This one is BY FAR my favorite. Most of my seedlings are in flats. Using the two bulb units, with the flat turned lengthwise under the lights . . .the plants on both long edges for about two rows on each side for a total of four long rows . . .the seedlings become slightly more leggy than those seedlings closer to the middle. The reason why is the distance from the lights. Using the four bulb unit, all the seedlings get the same amount of light.

No. A heat lamp would melt the plastic if it was too close. You can use a high output CFL plant light. Use a seedling heat mat and controller for warmth.

It is light, so you need some way to keep it in place. We use ours on a concrete patio, so some bricks sitting on the six inches extra fabric on the bottom works well. On dirt, there are holes in the feet where some wire tent posts would do the trick. Depending on your area a heat source may be needed. We use a "reptile heater" which is a fifteen foot rubberized wire we string around the plants. It puts out 50 watts very gently. If light is not offensive, a lamp inside will produce enough heat.

I'm very happy with my fixture. The quality is fine and I have had no issues. How can you mount anything if the power source is coming from the TOP?Wouldn't the source need to come from the BOTTOM of the beam?

The fixture has almost complete range of motion. It will tilt more to almost straight away from the base. Excellent light and very bright with almost no heat. I bought 3 to start with to put in our boat. I just bought 4 more. I'm putting them wherever I can think of!

HiWe do not have these lights under cabinet, we have them flush mounted over the sink so they're sort of enclosed. They do get warm. I can't easily access the fixture except where the 'bulbs' are. That surface is about 100 degrees according to an infrared thermometer. Wood ignites at around 450 degrees these puck are nowhere near that. I did feel the cabinet floor above the puck that has been on for a couple hours. It's barely warm. We had Xenon puck lights in the same location previously. Those got WARM, the LED puck lights are much cooler. For under cabinet use we went with the LED tapes, those are barely warmer than ambient.

Because if the heat from this fixture it is advised to mount like you would any light fixture. Take a lokk at your current fixtures in ur house. How r they afixed to the ceiling or wall. They shouls have a conection to the wires through a hole in the wall or ceiling that then connects to your electrical box/panel. I hope ths helps

I use a fluorescent bulb, so the shade does not get hot for me; but I believe that if one were to use an incandescent bulb the shade could get hot but you should still be able to maneuver the shade safely from the rear of the shade near the switchm

As I'm sure you're aware, 1200W will heat a room above the tolerance of about anything but cactus. A relatively tiny space such as tent will require MASSIVE air moving equipment and likely the tent you choose will not have any provision for such air movement. I would strongly recommend you research the lumen/sq ft requirement of whatever you're growing.I'm currently generating about 10,000 lumens. I have 5 fans (2 to ram air in, 3 to extract) and I'm still getting a 12 degree (F) rise over the temp outside the tent. Take care and have a fire extinguisher present.

Depends on the size of LEDs watts. but petty much will put out the same amount of heat. But lok I said it depends on how many watts you get with the led. I would recommend glow grow led lights tho

You would have to be sure the bulb does not touch the vinyl sides of the greenhouse, and that none of your electrical connections can get wet. Your electrical cord should be plugged into a ground fault circuit in case water contacts the connections. Other than that, your grow light should be fine. I used a heat lamp in mine last winter when the outside temperature fell below 28ºF, using the safety precautions I mentioned, and had no problems.

Dont worry it won't burn yr plants.I had mine 4in away.my plants loved it . Just make sure you have air circulation. Keep track of yr humidity. Good luck with yr plants .

I haven't seen anything regarding this but I would not hesitate to use them in an enclosed fixture. If memory serves they only draw about 1/2 watt so any heat buildup should be minimal.
