bahahaha first you need a Santa beard!
Sorry Djozz one more question how bad are these for your eyes?
30 minutes drive to your place man 
What is the diameter of the lens? If it is not more than 10mm, you can get a 10mm ZWB2 filter on aliexpress and get rid of the white background light. I never found a 12mm ZWB2 filter.
You Sleigh me …
depending on intensity, but: pretty bad, do not look directly into the beam and when looking at reflections: not too long. Checking a note for a moment is fine but do not stare for minutes.
Common polycarbonate protection glasses block 365nm very effectively btw
Shining the light sideways so its not as strong!
Yea the lens is 10mm i think its glued in.

I bought this one, and also made me an S2+ with the 3535 UV LED from LED4POWER ( I think ?) and a ZWB2 glass.
I’ll make pics when my Jetbeam shows up to show the difference.
Maybe I should have bought another UV LED from known source and put it in a BLF 348 instead of impulse buying the Jetbeam…
For who wants to try it, here is a (the only btw) Ebay source for 10mm ZWB2 filters (do not know about the Jetbeam, but it fits a BLF 348 perfectly btw):

Are there any decent AA nichia on the market approximately same price as convoy S2 uv?? if not why no manufacturer fill the gap…i’m sure few people would want!! 
Not that I know of. Tank007 sells some AA UV-lights, but I think they are expensive and way behind on the leds that they use.
There is AA light with nichia 365nm but it cost much more than convoy s2
JAXMAN E3 Cree UV Ultraviolet 365nm AA E3 Cree UV Ultraviolet 365nm AA
Forgot about that one (link does not work btw), it has the good filter but the led is weaker than the Nichia 276A that Convoy uses (but can be upgraded of course )
Is it possible put forward to the man “Mr Convoy” to make/produce AA nichia version for us BLF?? how does work and why hasn’t he done it yet?? mmm?? As stated by Mr djozz and Mr Nicolicous other UV expensive and ‘…out of date’ so clearly there a hole and $$$ to be made but no one willing fill??
Does this mean if i install/glue? this filter to my BLF-348 uv will improve/enhance?
If it has a 365nm led, it will filter out all visible light from the source, this enhances the visibility of UV-induced fluorescence.
just order 1 from GB, let see if it can do its job
This is the S2+ Nichia
Both pictures same settings manually setup
The UV is very intensive about 1W of photons, still its for my eyes not bright purple
Without zwb2
With ZWB2
By time i order zwb2 for 348-uv or for jetbeam-uv dam thing cost more then s2-nichia, so went back GB got another S2-nichia (especially now that they got them on special again) But cant wait for nitcore tube uv as the emitter same as MH27UV? or just another waste of money!!
