UV flashlight rough spectrum

Click to view full size image

Dor123 was curious of spectrum. Hope this helps, i know its rough. The dim light on spectrum is phone screen light, the violate blip is the uv (blb) flashlight

The photo shows the light colour properly. The subject is a white jar of gravol on a white background. The label reacts but not the rest. The light colour is almost like a Black light blue flourescent but slightly washout but pretty good for LED

Violet, NUV and UVA LEDs, usually have a broad emission from the red to the blue, emitted as a byproduct. Either the body of the LED itself fluorescence, or part of the die fluorescence.
Anyway, the violet part of the spectrum is too intense for a UVA LED at the range of 350-370nm. Looks like the violet/NUV 390-405nm one. They can also causes fluorescence on paper.

I"m don't speak English well, and rely on online translating to write in this site.
Please forgive me if my choice of my words looks like offensive, while that isn't my intention.

I only working with the European date format (dd.mm.yyyy).

I lives in Israel, which is a 230-240V, 50hz country.

Typically UV LEDs have a wavelength of around 395nm. BL and BLB fluorescents have around 350 and 360 respectively.
