Halogen 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.
These have held up well, they work well for the combo led with timer I have. It takes up less space but produces a nice nighttime heat for my bearded dragon.
The low profile nature of this lamp is great but you cannot use this lamp overnight. Completely defeats the purpose of this product because the reptiles can see the light at night.
I just bought this in October an it's already not working! I haven't messed with light at all and woke up to it off. I put the bulb in the other lamp and nothing! How did it burn out so quickly?! I don't understand why when these are supposed to last longer and be better.
