These lights are fantastic. I have a python, crested Geckos, leopard gecko, and gecko. They all require heat lamps and bulbs to maintain there heat in the habitat. These lights work amazing and keeping the cage warm and if the temperature that they need. I really enjoy how easy they are to use and how well and long they last. Shipping was super easy and the seller has been amazing. They came ways sooner than what they were supposed to and I'm really happy with my purchase I bought a couple of them and will continue to buy more.

These are a must have for all of my reptiles and so much cheaper and easier then buying them in the store at crazy prices.
