Reptile and bird eyes respond to ultraviolet light, which people cannot see, so a UV source can lose output without any visible change. This card gives keepers a simple way to check the UV output of a terrarium lamp at the basic animal level, without any equipment beyond the card itself.
Why it matters
- Fast reading: the card measures UV intensity within 10 seconds, so the check fits easily into routine husbandry.
- Clear result: a purple sun appears when UVB is present, and its strength indicates whether the output is low, moderate or high.
- Tracking over time: photographing the sun at each 14-day check allows direct comparison of colour and shows gradual loss of output.
- Replacement signal: a sun that becomes progressively paler indicates that the UV source should be replaced. The supplier gives a typical bulb life of 100 to 150 days.

What it works with
The card is intended for terrarium setups that use a UV lamp as the source of UVB for reptiles and other terrarium animals. Hold it directly beneath the lamp at the point of greatest intensity, and set the distance between card and lamp to match your own needs. Repeat the check periodically to confirm that the lamp still delivers the expected output.

Frequently asked questions
Hold the card under the lamp at the spot where the light is strongest. A purple sun appears within 10 seconds, and its intensity is shown as low, moderate, or high. If the sun looks paler over time, the UV source needs replacing.
Repeat the test every 14 days and take a photo of the purple sun each time. Comparing the photos over time shows whether the colour is fading.
Reptiles and birds have receptors for the ultraviolet range, and UV light supports vitamin D3 synthesis, appetite, and activity in many terrarium animals. UV output decreases with time, so the source should be replaced regularly, usually every 100 to 150 days.
Leave at least 10 seconds between consecutive measurements. This gives the card time to reset before the next reading.
The distance between the card and the light source depends on your own needs. Always place the card at the point where the lamp's effect is strongest.
