Review on 100W UVA UVB Mercury Vapor Bulb/Light/Lamp for Reptiles & Amphibians - Premium Heat & UV Source for Basking - Evergreen Pet Supplies by Brittany Smith

Very well packaged so it arrived safe and sound at a good price and I was glad I took a chance and ordered it. All-in-one lightbulbs are becoming increasingly difficult to find at local pet stores and cost twice as much when I can find them. I know these bulbs can be fickle - some last months, others just the last few weeks - no matter how much/little you pay for them, so it's nice to have an affordable option. I will definitely continue to order from Evergreen. UPDATE: I ordered 4 in total and they all arrived safe and sound, all caught fire and lasted at least 6 months. (I change bulbs every 6 months to keep UV levels high.) 100W produces enough heat to "tan" but not enough to overheat the tank. I will continue to order them as needed.
