Solarmeter Model 6.5R Reptile UV Index Meter, Handheld Digital Radiometer for Measuring Ultraviolet Light, Measures 280-400 nm with Range from 0-199.9 UV Index, Made in USA, ABS Polymer, Black

I am so so happy I decided to invest in one of these and can’t recommend them enough for any reptile owner!!! This completely takes all the guesswork out of the amount of UVB your reptile is getting and may even save their life! Without a meter we don’t actually have any way at all to make sure they are getting the amount of UV they need. Now I know exactly how much UV light he is getting, and I can check the bulbs to measure the output so I know when they need to be replaced instead of relying on just the manufacturer suggestion.When I first got this I tested it under my current T8 UVB bulb that wasn’t more than a month old and it was barely putting out any UVB at all. Had I just followed the normal schedule for replacing them, my poor beardie who is a rescue that had MBD as a baby may have ended up suffering because of it.Needless to say I got a new light right away, but this time I got the Arcadia 12% T5 (which is considerably more powerful) to go with the larger enclosure I was also getting, and I used my new solarmeter to measure the UVI at different locations in his tank and tested out putting the light fixture in different positions in order to help me properly place it so he has a healthy gradient.I know it’s expensive, but this is one you should definitely consider! It’s a one time investment that you’ll find yourself using time and time again and coming to rely on to make sure your reptile is getting what they need. Also impressive to see that each unit is hand tested, calibrated, and comes with a certificate showing you when it was tested and certified.

I keep bearded dragons. A couple of years back I had ordered new mercury vapor UV bulbs for my beardies but the regular brand I bought was out of stock, so I had to settle for what was supposedly a similarly reputable brand. I replaced 3 bulbs right away and within days noticed that one of my beardies was having trouble seeing and keeping his eyes closed most of the time. I worried but did not connect it to the bulb until a second beardie began having the same troubles, and then within hours, the third was also showing signs. I immediately removed all 3 bulbs as they were obviously the culprits. My two remaining beardies who did not get these bulbs had no symptoms whatsoever.All three affected beardies did recover, but the first to be blinded took the longest to get back to normal. I have since learned that this issue was almost certainly caused by dangerous UVC light which is the type used to kill bacteria and viruses, and is very harmful to living beings, and especially harmful to eyes. I've also learned that UVA and UVB bulbs created for reptiles are NOT well regulated or have much consistency even in the same brand. So having this meter to tell me exactly how much UV light is being put out by various bulbs, and at what distances from the bulbs eases my mind that I will never have my precious babies harmed by another poorly made bulb.Yeah I know this solar meter seems like a big expense, but it will save you and your beloved reptiles from what mine went through, and that is worth every penny.

Clearly works. Very helpful if you have reptiles. The UV varies alot as you get closer to the bulb, and as you move into or out of the center of the light. My bulbs are old and seem to be working fine so I'll save money on replacements.

The media could not be loaded. If you have reptiles please get this 🙏🏼.It is easy to use! The preformence of the product is a god sent... It is definitely worth the price if you care for reptiles or starting out with a new collection of reptiles that need uvb.I kept putting off on buying this because it's so expensive but one of my new reptiles I've had for 6 months (bearded dragon) was sick I didn't know why and I kept telling myself ill buy this later ( because of the price) but it is sooo worth it. I had bought some uvb lights of someone on ebay (be careful) the UVB was not strong enough.( I'm not to sure why but this product is expensive everywhere I looked.)

I cannot recommend this enough. It's so nice and possibly important to be able to read your UVB levels whenever you need to. There's so many reasons this is useful/necessary. You could have gotten a dud UVB bulb and you'd never know unless you can check it. Your UVB bulb might be puttering out sooner than the recommended 6 months, and you wouldn't know it. Your UVB could be working great, but placement to basking spot may not be giving your lizard enough UVB, and you'd never know it. That can be life threatening to your reptile over long periods. If your reptile is hiding more, you need this. If they have less energy, funny stools, lower appetite, you need this!! I use it every time I clean my bearded dragon's enclosure to make sure that I have his basking spot just right for proper UVB, and started doing that when I bought the meter and realized how off it was. I had a vet visit scheduled (still went, vets are great!!) and everything because he seemed so off to me. Never basking, barely eating. I used the meter and fixed his set up (bulb working great, but the basking spot wasn't getting enough,) and I swear he lept onto his basking spot and didn't leave it for two days. Since then he's been much more like himself. This isn't a replacement for vet visits, of course, but if you aren't getting your basic care requirements right then of course your reptile won't be in top form. And since there is no other way to make sure the UVB is correct, this is the way to go. You cannot rely on replacing every six months, and you definitely cannot rely on it working because light is still being emitted. That doesn't mean anything for UVB. I know it's expensive, but just get it. In the long run it will save you so much money, sleepless nights, and heartache.

Super easy to use. Seems to work great
