Quartz glass bulbs should not be touched with bare hands as the oils of the skin will significantly shorten the life of the bulb or cause it to shatter.
After years of living outside, we had a housefire and had to move into an apartment. We had tried a few different sunlamps, but either they made a noise, weren't actually full spectrum lighting (left an odd purple-reddish tint), or needed an expensive fixture. This lamp is perfect in the Zoo Med fixture we used for her indoor winter home. An inexpensive wide reflector fit the ceramic heater, and we now have a perfect, 90° F basking spot and MBD is reversed! Chewy, as always, excellent customer service and great shipping.
