It has a solid made switch, porcelain socket and a deep well for heat bulbs. I use porcelain heater bulbs to radiate heat for 3-ten year old snakes. These type of infrared bulbs last for well over 3 years before being replaced. Currently use a 75w. If your shopping around like I did you will be happy and content with this one.
