UVB Meter

The 6.5 was 190 last I saw. It really is the most affordable type in its class that I'm aware of. Otherwise you're looking at lab quality instrumentation and that's not cheap at all.
That being said, it's more of a luxury IMO as long as you have a trustworthy source for the information you need, such as distances for different bulbs, and uvi levels at different distances.
I have 1 because im a nerd and I like that kind of stuff. But i also had dragons for 20 years before deciding to get one.

I have the model 6.5 = OOPS MOMENT ON MY PART ] 6.2 Sensitive UVB Meter , and it's my goto meter.
I've also the model 6.2 = OOPS MOMENT ON MY PART ] 6.5 (UV- index meter) that I use mostly outside ( we get extremely high UV here ) , and the model 4.2 Sensitive UVA Meter . Sometimes it's worth checking UVA levels from a globe.
For monitoring the performance of multiple UV globes and tubes , the model 6.5 and model 4.2 are worth every cent IMO.
Not so sure about the value of the model 6.2 = OOPS MOMENT ON MY PART ] 6.5 OR 6.5R , as I'm not convinced UV-Index calibrations in these are properly designed for reptilian skins and I prefer direct UVA and UVB flux measurements over inferred measurements based on somewhat dodgy pseudo-scientific assumptions.
edit GOT tO stop posting in wee small hours when I'm tired.

Solarmeter's solar radiometers are all laboratory quality & calibrated instruments .claudiusx":3fzsn25l said:
Your numbers are backwards. The 6.5 is the uvi meter. 6.2 is the uv flux.
The problem with measuring UV flux is that the same number can mean completely different things from different sources. when measuring the sun, you know what to expect. The problem comes when using it on lamps as different lamps produce ratios that are different than the sun does. That's why francis has mentioned that a lamp that was only producing 50 mW uv was causing severe skin and eye issues. It wasnt until they realized that the ratio of short wavelength in that 50 mW was much higher than other bulbs or even the sun. So while being exposed to the sun at even 400 mW wasnt causing issues, 50mW of this specific lamp was. If your meter only can measure mW like the 6.2 does, you really dont know how much of that is actually shorter more intense wavelengths unless you rely on a chart. And if that's the case and you are going to rely on a chart anyways, there really is no point of getting the meter.
The 6.5 and the UVI reading specifically targets the wavelength range that is responsible for causing sunburns and d3 synthesis. That's why most companies/zoos/experts are using UVI now, as mW from one source can be drastically different than the same mW from another.
Hence the 6.5 being the preferred meter.
It's definitely not pseudoscience.

My suggestion to anyone who is going to buy a meter, is study the spec sheets very closely (available here : https://www.solarmeter.com/ )
and make sure you understand exactly what you will be measuring . And make the effort to research the actual climatic and environmental conditions the reptile live in the wild in their NATURAL RANGE.
.Don't go on the advise in magazines, and by resellers who more than likely are clueless .
Take a close look at how poor a fit the calibration model used is for the UV-Index meters , which incidently calibrate to mammalian (human) skin UV response NOT reptilian UV skin response.
Fergusen Zones ( https://www.solarmeter.com/pdfs/6.5R_UV-Index-Interactive.pdf )
are not a good guide IMO , even if trendy and the current pseudo scientific fad...

At the current expense of UV meters, it's a luxury that's going to have to wait. For the time being, is the guide I linked above (https://sites.google.com/site/thelizardmadness/lighting-guides) good or bad to follow?
