Emission spectra of different light sources?

[Fandyus]

Basically, I'd love to see if some good soul out there on this forum compiled a few different light sources' emission spectra (example: Fluorescent blacklight, blacklight blue, maybe a few UV LEDs, normal and halogen incandescent, reptile bulbs etc etc) to see just how much UV and other you can get from each of them. I would gladly do it but I don't own nor do I have the finances to get a spectrometer. It could be very useful for everyone's experiments here, though.

Don't go rushing to get your spectrometer though :), it's just a suggestion for if any extra dedicated members here ever feel like it.

We do have some of that here, but it requires searching out. Let me go get one link I know of and perhaps other members can point out others of these measurements.

(I'm actually not entirely sure what we do have.)

If I can get some good input here, I will put it in the Sticky

and also into a Pinned topic for future easy reference.

Yes, actually we have a lot of such tests over the years. Jonathan, JCDowdy and Ulf between them did many, and so did Enrico Savazzi?

 

Update:

 

JCDowdy and Ulf did the Convoy S2+ 365nm torch (these are independent tests):

Ulf did the Nemo torch:

Enrico Savazzi did the Exo Terra Repti Glo 10.0 UVB and the Exo Terra reptile UVB200:

Jonathan did the UVP EL series UVL-28 with 2x 365nm 8w fluorescent tubes:

Enrico Savazzi did the Godox AD200 electronic flash:

Jonathan did the Canon 600EX RT flash (please note that he redid this several times and the correct spectrum was the one in post 14):

I think you can find spectra for most of our usual UV light sources around here (most of which are above anyhow). The gap is actually on the IR end.

I have posted these before, I can't remember what paper I pulled them out of but can't find any of that information now.

COVID vaccine has killed my memory. Odd

 

The last image is the Exoterra UVB reptile lamp. You can see their spectra on their website.

 

Haha just found the paper and attached.

I would trust Enrico over the manufacturer on the Exo Terra, David.

 

Everyone should remember to take all spectra (regardless of how trusted the source) with a grain of salt, especially near the ends of the measured range. Usually if they could go further they would have, so it’s likely the data is low accuracy near endpoints.

Thank you everyone who responded so far! Very interesting information.

[Andrea B.]

Thank you also from me. I'm going to gather up those links as promised.
