2017 top 10 professional UV flashlight

Recommend the Convoy + ZWB2 filter (look at previous post).

I used my Convoy S2+ with the stock MCPCB a few hours and with Djozz board also an hour or so

I noticed that parts of the emitter start to get very dim, no color change like other LEDs had
I guess 700mA is not healthy for this Nichia LED on the stock star

As for UV flashlight, I think Tank007 TK566 is a good choice, professional Japan chip, dark glass as lens which can filter visual light and get more UV light.

Same led, same filter, but NOT the same price-range.

With such a high priced UV light, at least give the sutomers more than “japan UV emitter”…
You need to give them more information in order to justify this price.
The host doesn’t seem to have good quality, I really hope that this is a Nichia in there at least

im confused, whats the need for ZWB2 for the convoy uv flashlight? So i guess using the convoy stock light longer runtimes isnt such a good idea then, since it can damage the LED ? not good… perhaps simon should do a new version of it, anyone can contact him with the pics above?

@Henk4U2…… Thank you so much for the answers and link, I appreciate your time. :+1:

I have another question or so below………

  • So does that mean the Jaxman has a “Royalighting” UV-LED and not the Nichia as advertised?? (It never said this , I was mistaken)
    ………If so, is it “as good as” the Nichia? (I am just curious & trying to learn. :slight_smile: . )
  • Would there be much advantage to adding another 7135 AMC to bring it to 3*7235AMC total?? As long as the LED is on a good DTP board that is.
  • OK, I got mine through GearBest, that might be why it just has a clear lens. I’ll add a ZWB2 lens.
  • Leave it at 2*7135 AMC driver. Check………… :+1:
  • I’ll follow both yours and Dr. Ruth’s advice on wearing protection. :slight_smile:

Thank you again for being so helpful & thorough. :beer:

- I don’t own the Jaxman myself, so I can’t look inside it. But the picture of the UV-led on the Jaxman site sure looks more like the Royalighting led, reviewed by djozz, than like the Nichia led, shown in perfect detail in post #9 of this thread.
The Nichia is about 1 yr “younger”, so I guess it will be more efficient in emitting UV-light.

  • it looks like the Royalighting can endure 3*7135 AMC (3*0.35A=1.05A) when the led is mounted on a good DTP board. And yes, you hear a “but …” is coming up. When you look at the graph in the review of djozz, you notice that the forward voltage is quite high. In plain English: you need about 4 Volt to make that current go through the led. That is possible when you use a fresh off the charger 4.35V battery. In normal conditions, and with a “regular” 4.2V battery, you get 0.9A at the most. So the effective gain of adding an extra AMC is not very impressive.

I bought the banggood s2+ without a filter and had no problems. I installed a filter and saw little if any difference. Whoops! Yes I did! The light looks “cooler” now to the eye. I can also easily tell which light of that form is the UV light and not the white light. it works identically to the user with or w/o the filter from what I remember. I also use mine just a few minutes at a time. Heat might be a problem if one used it for longer, but it isn’t designed to be a mineralogy display light. I’d never pay close to $300 for a UV light when the s2+ works so good and has so much going for it. Just remember to turn it off and on as required. It’s no big deal.

Your advice is good. Thanks. But a real Nichia UV chip is more expensive than our TK566 flashlight.

Thank you again Henk4U2…… :+1: … I had forgot the Royalighting LED picture was on the review you gave the link to. I guess I had a senior moment. :person_facepalming: … :wink:

  • But you are correct, it does look more like it. I am gonna locate my magnifying glass and check for sure tonight.
  • I see that adding a 7135 AMC ‘chip’ won’t do much. Thank you for explaining why. :slight_smile:

I am beginning to be fascinated by these UV LED’s…… :slight_smile:

JAXMAN U1 365nm UV LED flashlight special purpose

OK, I found my error with your help Henk4U2.

The Jaxman UV light I got, listed above; never claimed to have a Nichia in it.
Just like you said, from the picture it appears to be a Royalighting.

I was confusing the Jaxman I bought with the Jaxman shown below…. which cearly has a Nichia in it.

My bad……… :person_facepalming: … :wink:

^ The Tank007 UV lights are way overpriced.

I do not like professional UV-lights, our own build UV-lights are miles better and cheaper. The only stock UV lights that are worth considering are the Convoy and the Jaxman.
But of course I’m not a professional…

I’m glad this thread is revived. I have been threatening to buy a UV light, but I have no idea which one. The only use I have for one is to recharge glow-in-the-dark fishing lures. What are some other practical uses for UV lights?

Can anyone tell me what UV-LED and what lens are used in this flashlight?

I assume a 5W Nichia-UV LED is not as expensive as a CFT-90 and the lens is something ordinary with a ZWB2 filter.

I’m pretty sure that the lens is a ZWB2 filter and the led probably is a Seoul Viosys led. It is a pretty new light for Tank007 and almost certainly the design was inspired by modded lights posted here on BLF. The DIY build costs are about 40 dollar so they make 1000% profit.

Get this light, small, simple and lots of 400nm light to charge your lures, works on a CR123 or a 16340 battery.

highlight scorpions in the desert ? :smiley: u have those where u live or

get the convoy, its very darn bright for a uv light and runs on 1 18650 battery.

Thanks guys for the recommendations. I like the price of the light that djozz mentioned. Is there a big enough performance difference with the convoy s2 to make it worth 3 times the price?

The main difference between the two lights is the wavelength.
The Fasttech light has 395-410nm (it is at the edge of UV light) it is a bit more purple/blue and i would not use a ZWB2 filter on this light.
The Convoy light has 365nm. Real UV light and if you use a ZWB2 Filter you can only see a bit of light untill you hit a object that reacts to UV light.
LEDs with shorter wavelength are much more expensive than the purple ~400nm LEDs. So it is normal that a light with 365nm LED is a bit more pricey (if the hosts have the same price).

It all depends on what you want to do with the light. Many disco UV lights use both. Short wavelength LED´s and 410nm+ LED´s. Because people know the old UV fluorescent tubes with purple blue light ( ~390-490nm). And they want the same feeling. But if you want for example cure Uv glue i would buy a 365nm or a 385nm UV LED. If you want to sterilize water you would use LED´s with 200-315nm.
