Cadmium Posted March 5, 2017 Share Posted March 5, 2017 My tests of the UVEX Ultrasonic 9302045 goggles.A while back my friend gave me these excellent goggles as a gift (Thank you! :)).These are very comfortable goggles, they block out any side light, they are very well built, and these block UV better than any of my other UV eye protection.This model has two lenses, the bottom clear lens, and the upper flip down dark lens.In all of my test shots, I am testing each lens individually (not in flip down double lens 'stacked' mode).Both lenses seem to block UV-A completely.The clear lens passes some of the UVB 200 Reptile Lamp transmission, flipping down the upper dark lens will block that.These two lenses stacked together provide probably the best UV protection I can imagine.This model even claims to be good for "Welding protection model 9302.043/045".You can see fairly well through the dark flip down lens filter of these goggles, which is not anywhere near as dark as a #12 or #14 welding glass filter(which are impossible to see anything through except the sun and electric welding), so I will not trust my eyes to these goggles to weld with.I do some electric welding, and I know how strong of UV electric welding produces, it will give you a severe sunburn if your skin is not covered.

Andy Perrin Posted March 5, 2017 Share Posted March 5, 2017 Colin, water absorbs UVB pretty well, so I imagine low humidity (and possibly high elevation?) would be situations with more than the usual amount of UVB. Link to comment

OlDoinyo Posted March 5, 2017 Share Posted March 5, 2017 I see no evidence that the "UV-B lamp" emits any more UV-B than the other lamp. Both are just mercury-vapor lamps--one just has a UV-A-blocking coating on it (what the benefit to reptiles of that might be, I cannot say; the wavelengths below 280 nm do not correspond to anything found in sunlight at ground level.) I suspect it is no more dangerous than the "ordinary" black light (which should of course be treated with respect.) Link to comment
Cadmium Posted March 6, 2017 Author Share Posted March 6, 2017 Hi Clark, I may have misread the graph numbers of the Lizard Lamp (what I call it). The image was a little small, so I blew it up here. Is this how it looks to you?290 340 390 440 490 540 590 640 690 740 I was reading the 390 as 300, and the 440 as 400 before, and I thought the 290 read 250, which still looks like 250 to me, but not if you follow that progression of numbers, so sorry.So it really should have more transmission peaks in UV-A range on the Sparticle. I will try testing it again sometime, but that doesn't make sense to me. It should have more power than the Black Light bulb also.I have not tested the Lizard Lamp before, so I probably should not have used it in the UVEX goggle test.http://www.exo-terra...tile_uvb200.php Actually, here is a much clearer picture of the graph, photographed off the box the bulb came in: Sorry for the previous confusion.

Andy Perrin Posted March 7, 2017 Share Posted March 7, 2017 Isn't UVB between 280 and 315? UVC starts at 280 and it has none, but it looks like there is plenty of UVB in the lamp. (But maybe the same as the other.) Here, I redigitized it using a program I have for extracting numbers from pictures. Link to comment

Cadmium Posted March 7, 2017 Author Share Posted March 7, 2017 Yeah, I know... :-) The wiki link was agreeing with you.This was more about the goggles.Enrico started a new topic about bulbs, one of which is a very close model. Green graph:http://www.ultraviol...orescent-lamps/ Link to comment
Andy Perrin Posted March 7, 2017 Share Posted March 7, 2017 Okay, the goggles look like they do the job? Glad to know that! Link to comment
Cadmium Posted March 7, 2017 Author Share Posted March 7, 2017 I tested the two bulbs in live view just now. The Black Light (13W) and the Reptile UVB 200 (26W),and I can clearly see light through all of the Sparticle BP filters with each bulb,however the Black Light is much stronger, and doesn't require much exposure time compared to the UVB 200.The black light also is more even, with about the same brightness through all of the BP filters,where as the UVB 200 has less brightness in the upper UV BP filters compared to the middle and lower BP filters.So basically the UVB 200 bulb, although it is 26W compared to 13W, doesn't have as much light power as the Black Light, and not as even.That is why it looks so dark in my comparison shot of the two bulbs above.Visually, of course, the 26W UVB 200 puts out a lot more light than does the 13W Black Light,and that may be where all those extra watts are being used, for the visual part of its spectrum which the Black Light doesn't need.The UVB 200 might be handy for filters and lenses that transmit in a lower UV range, like around 300nm to 350nm, but my lenses will only transmit down to about 320/325nm,and my black light puts out more UV brightness in that range than the UVB 200 does.

colinbm Posted March 7, 2017 Share Posted March 7, 2017 The effects in UVIVF might be different with different subjects.....medium wave & long wave UV excitation ?Col Link to comment
Cadmium Posted March 7, 2017 Author Share Posted March 7, 2017 This Lizard Lamp is really getting popular! ;-)Anyway, here is a shot of the Black Light and the Reptile UVB 200 bulb side by side., and yes, they are both plugged in and powered up, it almost looks like the UVB 200 is not turned on, but it is.This will show you how much brighter the 13W Black Light is in UV-A compared to the dimmer 26W Lizard.Shot with Kuri 35mm/Baader U. Here is a pic of the two bulbs in visual. Link to comment
