Can you please tell me the emissivity and thermal conductivity?

Sorry, I cannot answer this one. I used it for making solar cookers. It is very reflective, and I like the 2 mil thickness.

I can't say the exact temperature but it is not a warm light at all. I would guess around 6000K.

I haven't tryed heat emitters in it yet . So far I have only had a Exo Terra Repti Glo 10.0 UVB compact 26w in it and it's been working great ! . If you put a emitter in please let me know how it works :) .

Color temp is around 5000K. As for lumens it's hard to tell. Maybe 100-150 lumens

I don't know the output in lumens, but for my model the color is daylight or cool white, not warm white like and incandescent. Possibly you can specify a color temperature?

The previous answer is satisfactory but the measurements are not exact, neither is the temperature.

Lumen is the brightness and its about 500 Kelvin, daylight brightness. Hope this answered your question. If you like white light you will be pleased with its brilliance

Although I don't have the nM wavelength information, the light is a bright White color probably more to the Cold color than the Warm color. See photos on the listing.

The package comes with two 250W halogen bulbs. The color temperature is warm. The bulbs generate a lot of heat. The metal reflectors are too hot to touch.

There will be heat coming from the lamp due to the flow of photons in this portion of the electromagnetic spectrum. However, UV-C may, under some conditions be visible, but you should not look at the light directly at all. A photometer can be purchased at a very reasonable price that will positively confirm the devices function and they can be purchased on Amazon and can tell you how well your device is working. I hope this helps.

There is no heat, this is an LED lamp. Keep your hands under it as long as you want.

2700K color temperature. If you look at the bottom of the page, all the specs are listed.

Its what you are referring to as harsh white. Its a very high color temperature, although I dont know the exact number, I could say its about like 6000 Kelvin LEDs. And the light output is very high, brighter than my 50 w halogens which it replaced.

Unfortunately I cannot answer the wattage question, but I can tell you that we burned through 2 sets of these in less than a year. The output is amazing and clear however due to this temperature it appears that they will need to be replaced often.

I don't see anything in the specs about operating temperature. So sorry, I can't give you a specific X-degrees. I used them in eight open track light fixtures in a kitchen, and did not sense any radiated heat. But they are definitely very hot to the touch, and I would not use them in closed fixtures. Actually, I've moved and have some leftover, which I don't need. Allen

Can't really answer this question. Air passes through but not sure about amount of light. Sorry!

these peak at just under 300F when they are on. the dish itself is a sort of sheet steel meant to reflect radio waves back at the antena. the steel will glow red hot around 1000F. too hot for the material... maybe not, will it cause damage to electrical components or interfere with reception... i dont know
