Love these second time ordering these will be back when I need more

I discovered a while back that of all the bulbs I have tried, halogens seem to be the best at efficiently putting IR radiation (heat) where it is needed for reptiles. I accidentally broke the lens on one once and noticed it put out more heat. It seems that most glass partially absorbs certain wavelength of IR to some degree. This bulb actually does a better job at providing heat to my bearded dragon than the small 25w ceramic IR bulbs that I tried, which sends heat in all directions. The only downside is that that the glass lens absorbs quite a bit of IR. I deliberately broke and removed the lens from one to test IR transmission through glass. To my surprise at several inches away, the one with the lens intact raised the temperature of the surface to 145F and the one with the lens removed raised the temp to 165F. Because animals absorbs IR better than most dry materials, the difference was even more noticeable when I measured the surface temperature of my bearded dragon. After it had been under the one with a lens for some time at a distance of 10 inches, it was at about 95F, but after switching to the one with the lens removed, it measured 101F, which is almost perfect for a dragon. Keep mind however that this is supplemental heat. I also have a 70w metal halide at about 16 inches away, but it does not provide enough heat. This bulb almost makes up the difference, but I think I will upgrade to the 35w which will be a more optimal combination. Also, I used a color changing UV test card both with and without the lens, and there was no difference, but in both cases the UV output was very low and barely registered and is nothing compared to the UVB output of the metal halide.

Love the brightness and the ease of use

I just got these lights on Tuesdays the light fixture I am putting in is 3 lights Ive already had to replace each Bulb...theyve lasted one day

Beware - I purchased these and have replaced each one of them at least once since November (7 months ago). Keep track I would say they last roughly 3-4 months each, while the old ones are still burning brightly in the lamps. STAY AWAY!!!!

This is exactly what I needed for my scented wax warmer.

Great lighting works perfectly!

Used for waxmelts

They fit my tart warmer perfect.

Bright, reliable, durable, and warm. I am very happy with this product. The price is good. They last forever. I highly recommend it.
