Reptile UV Test Card — UVB Bulb Tester for Terrariums & Basking Lamps

This UV test card lets you check whether your reptile's UVB bulb is still putting out effective UV output, since bulb strength fades over time even when the light still turns on. Reading the card regularly helps you know when it's time for a replacement bulb.

A simple, low-cost way to make sure your reptile is actually getting the UVB exposure it needs for healthy bone development.

Ideal for placement:

• Bearded dragon and gecko terrariums
• Turtle basking areas
• Any reptile enclosure using a UVB bulb
