—————————————————————————————————
summary—-
it seems ok really
the thing is, i am not really sure what it is supposed to do
what color the light should look, what should glow, what shouldn;t, with this exact UV type
there are so many UV types, at least 4
it has more visible light than my old fluorescent, but maybe it is supposed to
i hate twisty switches but i knew that going in
only has 1 mode, for some reason i thought it had low and blink mode
maybe 1 mode is for the best, i hate multi-mode twisties even more
—————————————————————————————————
what i liked—-
it is made well
seems waterproof, only one threaded opening
even the usb port can be covered by rotating a rubber ring
-not sure they intended that but it is possible
usb charging is convenient
it is very small and light, due to TIR optic, floody pattern, and no tail switch
shipping was 2 wks from china, fast
cheap, seems like a good buy mostly
—————————————————————————————————
what was questionable—-
it seems to make a lot of non-uv light, greenish yellow, maybe that is what 365nm UV looks like, i don;t know
it is kind of dim – NOTHING glows in day light, even regular room light overwhelms most glows
money especially glows very dimly, you have to be in the dark to see the glow stripe
claimed 90m range, no way – 9 feet is more like it
cannot take apart, driver seems glued in
no clip, but i don’t really use them
extremely bad instructions
—————————————————————————————————
what i didn;t like—-
only one mode
twisty switch – though to be fair it is a good twisty at least, a little firmness in the twist but not too much
odd beam pattern, neither flood or spot hard to describe
would be better if it was a flood but then the light would need to be brighter to spread out
it is too spotty most of the time
you have to turn the light on with the twisty, to charge it
weird but without doing that, the battery is not connected to the top part of the light, where the charger and driver are
then when you unplug it it turns on because it is on via the twisty switch
(it doesn;t stay on when charging at least, it blinks dimly until charged, then quits)
—————————————————————————————————
notes—-
i have not tested on scorpions or cat p*e
have tested: diamond, fake diamond, american money, visa cards, etc

If you want to see what some people do with UV lights look at this site Nature’s Rainbows . There is a post there on the Convoy S2+ with the Nichia emitter. Honestly I think this is the light all budget UV light should be judged against. For $20 I think you should just get the Convoy and forget the others. Thanks for the review though, you never know what you will find.

what is wrong with TIR and 365nm UV though?
wouldn’t it have been cheaper to use a mirrored reflector, so my guess is, TIR does something desirable…?

UV doesn’t pass through PMMA too well, or hardly at all.
I guess the little UV Jetbeam uses the proper material for their TIR, but unfortunately it has no filter (you know, the ‘black’ glass lens).
Do you have a link to this light?
Can’t find it on AE

O, Okay.
I.i.r.c. Djozz has a zoomie with UV LED, i think with a plastic lens.
Thanks.
Nicron.
It’s a nice little light, also available with white LED (of course).
yes, the white one apparently has high, low and blinky modes

You have a point.
On the other hand, and not meant to offend you: a light that emits more visible light than UV light is pretty useless IMHO. Read the reviews on this site, or on the site https://www.naturesrainbows.com/ . The Convoy I got came with a ZWB2 (black) filter, but you can buy them separately. It is a world of difference. This filter blocks the visible light, so we don’t have to ask ourselfs constantly, was that fluorescence or wasn’t it.
You are a flashaholic if you are forced to come out of the closet, to make room for more flashlights.
Nope, my UV zoomies have a glass lens swapped in.
Polycarbonate is hopelsss at 365nm (Carclo)
PMMA works, but blocks quite some 365nm light too (Ledil)
The OP describes a led that sounds like 365nm, or close, so perhaps a PMMA TIR is used.

all i know is, there is some visible light.
i can;t see the UV, so how would i know what the ratio is?
i do know the light gets warmish in a minute or so, so i assume there is a lot power going somewhere, i hope it;s to the UV, not just the visible part, or the heat itself..

This might interest you perhaps, it’s on a discount at the moment:

Most 365nm leds emit some white/yellowish/greenish light, that is apparently inherent to the design principle of these leds (385nm and 400nm leds do not have this). Nichia 365nm leds are better in that aspect, the amount of visible light they emit is minimal (but not absent). Compared to the invisible UV-light, the visible light is only a small part of the output, but it can blur any fluorescence that you want to see.
To get an idea of the ratio, point the light at a piece of white photocopier paper, the blue fluorescence (that is a measure of the UV that it comes from) hugely over-shines the visible light from the led itself.

Some cheaper plastics will turn brown and otherwise degrade with cumulative UV exposure.

so – given that this thing puts out a lot of bluish light, would it make sense to get a small piece of woods glass and add it to the front to filter that out?

Yes that would help a lot, I have several UV-flashlights that have such a filter, the chinese version is called ZWB2 (and Schott uses UG1)
I tested such a filter a while ago for flashlight use: http://budgetlightforum.com/node/41697

I have the S2+ with Nichia LED. Pretty powerful. compared to my other UV lights (Kaidomain WF-501B with cheap UV drop-in + Convoy S2 bought few years ago).
Also, you can buy something like this for blocking visible light: https://www.banggood.com/365nm-UV-Flashlight-Visible-Filter-Lens-1pcs-p-.... Along with 18350 tube it will be pretty short light and still giving loads of UV…
Acrylic lens give a little fluorescence in UV, so may add some of the visible light as well.
Edit: sorry, didnt realize that editing can bump the post
I decided to get one of this during a promo flash sale in AliExpress.
It does emit a lot of visible white light (seems to overpower the UV light).
But if I place a ZWB2 filter (I only have a 20mm ZWB2 filter which is too big to fit inside this flashlight, so I only held the filter in front of the Nicron B10-UV), after that, the visible white light is now mostly filtered out, and what remains does look like 365nm wavelength UV (when compared to my Convoy S2+ UV365).
I’ll try to take some pics sometime for comparison..
yes that is what i did too, glue a ZWB2 filter and that fixes it.
what the visible light does is, it overpowers not the UV light, but the light that your test material might make
unless it makes a bright blue glow, like white paper or a tshirt does, you can;t see it in the whitish light from the nicron
anything faintly glowing is hard to see
it’s still a good toy for $10 though
or less

For what it is worth, I contacted Nicron about their B-75 light. It showed up in one of the coupon offers on BLF but doesn’t look like it is showing up on their web page yet. It is a rotating head light with both white light and UV emitters. The description said 365nm in one place but 395nm in another. When I asked about this they said the 365nm was a mistake and the emitter is 395nm. I am guessing that the inexpensive twisty has 395nm too. If so it will limit the usefulness for UV.
Edit: Sorry, here it is https://nl.aliexpress.com/store/product/NICRON-Magneet-90-Graden-Twist-UV-Wit-2-Color-Oplaadbare-Zaklamp-18650-2500-mAh-Ion-Batterij/111575_32833496892.html?spm=a2g0z.12010615.0.0.4dd12017DDxiKL . They have changed the web page some since I first saw it.
