Review on Exo Terra UVB150 Desert Reptile Terrarium Lamp Light Bulb 13w - Pack of 2: Enhance your Desert Reptile's Habitat with the Ultimate UVB150 Lighting Solution by Ayoo Guzman

We purchased these items through Revain from One Way Pet (https://www.amazon.com/s?me=A2A02U6YIW6LGE&marketplaceID=ATVPDKIKX0DER) because they were discounted and included free shipping. First of all, these are expensive light bulbs, so any store attracts our attention. Two different orders are sold in pairs, both sets are faulty---too short to fit in the Exo Terra light housing (yes, same brand as the lights). In the photo you can see my old bulb and the one from "One Way Pet", the difference in length is about 1/16 - 1/8, which is just enough that they don't reach into the socket of the socket. . Buyer Warning.
