BTW it is not Nichia as mentioned in the video (it was advertised as Nichia on aliexpress).  Someone said Edison, whatever.   A 3W Nichia NCSU033B one was selling for usd300+ on aliexpress.

I tried to take a video of the O-Like 400nm RAW diode output with the same settings as the 3W 365nm LED, not good it just overexposes everything.

Tomato worms are known to fluoresce under a blacklight and she wants something that could be used to sweep tomato plants after dark looking for them. Which UV lamp would be the best projector?

380+ nm LEDs are much brighter (and cheaper) than 365nm ones, so if the worms fluorescence under that wavelength it could suffice with a 12 LED UV light from DX for under $5. Even the 5 UV LEDs of the 3-in-1 light is brighter than the TK.

I have the Tank007 PT30 3W 365nm version, which has 3 of the LEDs of the TK-566 and also a slightly larger reflector.

I may buy one if I can find one cheaper than the tank007store...

Yes, I wonder why most other banknotes have so boring (or nonexistant) features.

I managed to take out the front glass cover of the PT30 (it was screwed in very tightly), seems to increase the UV light intensity by a wee bit. I gauged it by bouncing off toilet paper.

Just to give an idea on UV LEDs (3W 365nm Tank007 PT30) vs very very near UV 405nm 400mW....

First one is Tank007 3W 365nm. Second is Laser diode RAW output.  The laser diode output is CRAZY, the hotspot is like spread over 2X of what is visible here.  As you can see the top of Doraemon's head is fluorescing brightly.  I underexposed the LED so as to accomondate the LD output, in real life it is much brighter than this.

Still have them? Why did you not send them back for a refund along with the postage?

Wow, with the plastic lens removed it revealed another band of details (the orange ones).  For my PT30 the lens is glass, it just cuts maybe 5-10% of the UV intensity...taking it out does not reveal more details.

Looks OK, but it mostly depends on what you want to use it for? For example, It will be useless for checking UK currency.

The notes that don’t have the UV so visible are harder to copy. Also you might not be using the correct light to see the marks as it is quite visible on all of the lights except the TK-566. It’s all about using the right wavelength and not shining a tons of blue/violet light at it like most lights did. I think they are still too much in the visible spectrum.

I was just playing with my Inova X5 UV and decided I wanted to see if the UV would make a glo-ring light up better than the regular LED it was installed in.  

 

I wasnt expecting the LED in the light to start glowing but I realise now that I should have. 

Anyway after checking out all my lights that are within easy reach and I think I've got a way to verify that the tint I ordered is the tint I recieved. 

 

My warm white LED glowed red, neutral (and some sold as cool) white glowed orange, and the cool white glowed plain white. 

 

Can anyone else back me up on this?

Well spotted!

I don’t have any warm white LED’s but can confirm my Neutral ones glow an orangy/pink and cool ones white.

You could well be onto something here! Gonna watch and see how this develops.

Took a picture using my 365nm uv led to show what shur found.
On top is neutral, warm and a green led.
The lower ones are all cool white and didn’t show much but there is a Nichia 219 glowing pretty nice bellow the warm white.

I posted this a few times in various threads. I take it that no one has any experience with the Solarforce UV drop in? It is a low voltage 3-4.2v drop in designed to run best on a single 18650, RCR123, or CR123 battery.

Thank you for the review, mfm! ^^ I was just thinking I need a better UV light (AA preferably) and the Tank007 TK-566 sounds perfect.

Yes, I’ve got one. I’m fascinated by the differences when you bounce UV light off things.
The drop-in is very good for what I bought it for – charging up Glow in the dark objects, strong enough to light your way at night, about a 20ft. beam, there’s quite a lot of “normal” light emitted along with the UV.
I’ve just ordered one of these, it might be better still.
I use 550 paracord a lot and some of the colours fluoresce strongly under UV light, they look strange having two colours on a strand of camo with 3 or 4 colours shine brightly.
