Review on UV Sensor Card - 2 Pack - Reptile Lamp UV Sensor Test Card for Bearded Dragons, Lizards, and Reptiles - UVB Fluorescent Lamp by Tim Arnold

This product saves lives. When my bearded vet's vet told me that UV lamps could still emit light even after the lamp stopped emitting UV rays, I wasted time and money visiting an exotic pet store every two months to get their UV replace lamp. Now I can use this card to benefit from each onion and make sure my little pal is getting the nutrients he needs. Checking the status of my lightbulb only takes 10 seconds, which gives me a little more peace of mind. I tested the cards under 2 different lights and found that the test range gave different answers for each, so this seems pretty accurate. The set includes two cards, each packaged in a black envelope for longer storage. The cards are designed for 500 uses and are a very worthwhile investment for any reptile owner. All reptile owners should have them.
