Review on 🔆 Exo Terra Solar-Glo Mercury Vapor Bulb, 80 Watts, 80W by Jen Schuelke

Perfect for my hermit crabs! I have an Exo-Terra 36 x 24 x 18 terrarium and use it on both sides. My crabs run both day and night and are much more active with these bulbs. Since these are mercury bulbs, they can turn off and on again if you hit them while you're working. It is in order. I don't turn them on until they're in place and operational, and I have no problem with them flickering during the day. I turn them off at night before placing them on top of an Exo Terra night light and a Flukers ceramic heating pad. I love these lights!
