UV flashlight 2020 test:

I've been ordering (and waiting on orders) of UV flashlights since Q4 of 2019. 

I currently have received 6 UV flashilghts so far: 

Jaxman U1

Jaxman U1C

Convoy S2

Convoy S2+

Weltool M2BF

Cheapo 

 Still waiting on the following:

  • Jetbeam Jet UV,
  • Olight i3 UV,
  • Ultrafire SK68 UV
  • Manta Ray S1

I still have a Sofirn UV light en route, but I canceled 1 order of 3 UV lights. 

In another thread people recommended the Jetbeam Jet UV. What other new UV flashlights are interesting to test? 

Also, if you have any ideas about testing, let me know.

 

I was thinking about testing different objects: 

  • money
  • liquid/dirt on carpet
  • etc.

Just a variety of suggestions for things to test:

1) Money (if you have any other currencies from travel, that would be cool to compare them)
2) Stamps
3) Driving license/passport (obviously can’t upload the personal info to a public forum)
4) Rocks/minerals – Calcite, fluorite etc
5) Anything with optical brighteners will really pop, laundry powder, highlighters, bright colored plastics, etc
6) Some food and drink- tonic water with quinine will glow bright blue.

Looking forward to seeing your thoughts on the list of lights you have!

I use my UV light (with Nichia led 365nm and UV filter, both from Convor originally) while cleaning home, near the stove, kitchen, etc.
The other UV lights I have (395nm) are not as good to show grease and other stuff. So that can also be a “testing spot” Thumbs Up

We use our Convoy S2+ UV with a ZWB2 lens primarily to find dog urine around the house. With lighter carpeting, it’s pretty easy to find the yellow spots, but with darker carpeting, it’s nearly impossible to find without a UV flashlight.

Not sure if you have the same problem in your household ChibiM, but I’m sure BLF members with pets would appreciate a test that helps find these accidents.

I’d rather use my flashlight around the house than turn on the lights.

As a corollary, could you please look at the performance of a few ZWB2 filters also?  What to look for in an online ad that would indicate a genuine filter, or worse, a fake filter?  Perhaps a quick & dirty way to test at home?

I'd like to be confident that a lens touted as being bandpass for ~365nm really does exactly that, and isn't just a piece of overpriced (or insanely cheap) dark glass or plastic.

Great... Carnac the Magnificent tells me I just signed up for yet another expensive hobby.

Smile! It makes others wonder what you've been up to.

For the test you should probably mention how close the light is from whatever object you look at. Some small UV lights are only really usable at very close range. A fixed arbitrary distance test for all lights would certainly be meaningful.

Good stuff.

Any recommended UV flashlights you want to see reviewed?

 

I'm waiting for ordering the Olight i3 UV and Jetbeam Jet UV next week. Fasttech had a 10% discount on all products on April 1st.

 

Any higher end, popular UV lights?

Good point. My AceBeam UC 15 has one but it needs to be up close unless in total darkness.

I'll try to keep that in mind.

 

Does anyone know of any other UV lights that are popular?

How about the new MF01 UV (full size or Mini)?
It is supposed to be UVC+UVA to use as a sterilizing tool… so it probably does not compare to the others?

I thought about that as well. But since it's used for different purpose and at the same time a little more 'damaging'  in use, I don't think it's wise to add.

I’ve got a little Olight i3UV coming as a bonus item, so I get to see what all of the fuss is about?

It should work fine for a small UV keychain light.

I concur on the distance test. I have been keeping an eye out for a good UV light to check for scorpions. Having to get within a few inches to see them would not be ideal
