They say that they don't produce any heat, but I don't buy it. How warm do they get?
I guess I've changed my mind on the fixture setup (originally planned just 2 stainless shop fixtures), I just need to know a good way to mount these. Preferably some method where Fredrick cannot touch it, it's mounted flush with (or above) the ceiling, and so it won't get too hot (which could damage the enclosure ceiling panels).
If I don't hear much, I'll post pictures of the enclosure after I assemble it so you can get an idea of how much space I have to work with...

The bulb must produce some heat...?

The ad says they don't produce heat on the bulb itself. So the bulb is safe to touch for both you and your ig...this is absolutely true. The MR Heat bulb does this through efficient emission of IR radiation. The surfaces of the bulb don't absorb the IR, so its surfaces stay undamaging to the touch. In the direct path of the IR rays however, prolonged exposure can become dangerous if proper minimum distances aren't observed. To determine a safe distance, place a clear glass of water in the intended basking spot for your ig. The glass MUST be clear glass, and not colored in any way in order for this to work. After the glass of water has been in that spot for several hours, measure the temperature of the water. If its always below 98 degrees, then its a safe distance from your ig. Every heat source depends on distance and ambient cage temps. The MR Heat is a very real, effective source of heat, just be sure to observe minimum distances for prolonged (usual) exposure.  MR Heat is an excellent way to heat your ig. Remember, igs are Heliotherms and Helios was the Greek sun god. They get their heat from the sun's IR rays. Just follow the "glass of water" method, and it should help you. Be warned...a conventional thermometer directly exposed to these rays will give falsely high readings due to its metal parts being heated by the IR. Clear glass of water in the enclosure for several hours...take glass out of enclosure and measure water temperature. 92-98 degrees is a good optimum hot spot for a healthy ig. |

Depends on which product you are talking about and I don't know which of the decives you are.
I run both the MegaRay EB 60W, I would say it gets as warm as a standard 60W bulb.
I also run the 60 MegaHeat Heat Projector. This things takes a while to get used to and use correctly. The device gets warm enough you don't really want to hold your hand on it but you could with no real problem, but about 12" away from the HP surface is a focused warm spot about 6" in diameter. This device only really warms that small area and has little effect on the ambient temps. This thing gives off less light than a 3 W orange Christmas light (one of the small modern ones, not the big screw in type).
I have both the HP and the EB mounted in a corner on a 45 deg downward angle so the sweat spots for each "bulb" hit the same spot on the shelf. This spot ends up being about 12" off of Bob's back when laying there.

Does the EB screw into a normal socket? What are it's physical dimensions?

The EB screws into a standard lamp base, that is then pluged into the ballest (just a black box) with a standard male two prong Edison plug.
Size: abou 5 inch face diameter (wide) and 6.5 inches from face to base (tall)
