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 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.
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.
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.
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.
