This is well worth the money! i have adjusted the lights in my creatures terrarium to accommodate the lighting requirements. I was surprised when his colors started to really pop! A must have for anyone with creatures that need UV light.

Perfect to measure & track life of UV bulbs

If you are keeping reptiles, especially diurnal, this device is a must have. It will also save you a lot because you will be replacing your UVB bulbs when their output really drops, instead of having to replace them once every few months. With this device, for example, I have found that my 20W Zilla brand UVB10 bulb was as good as new after a year and a half of daily use, whereas a Chinese MH bulb, with which I had high hopes, produced zero UVB.

This device is very useful for reptile keepers. It monitors your UVB or mercury vapor lamps very well. Also, you can determine the best distance from the lamps to your reptiles.

Mine works great, I really like it and got mine for a price I could afford.

Works great, easy to use. Recommend for family and friends.

GReat device works as it should no issues. 👍

Is the industry standard for UVB index for reptiles. Works great.
