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 As stated by Mr djozz and Mr Nicolicous other UV expensive and ‘…out of date’ so clearly there a hole and $$$ to be made but no one willing fill??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!! 
The Jetbeam looks okay compared to the Convoy?
Still waiting for jetbean uv from GB (man mine is pre-oder, still not here yet!! how you get your so fast?? ) but going by your pics think convoy way better…more distinct especially with red eg like #5 post by ‘djozz’ pics. Can’t wait for my tube-uv as well to compare with jet-uv, got a feeling tube might have the edge…bc stumble on statement that use same emitter as their bigger more expensive MH27UV…guess i just have to wait and see.
All you really need are the Nichia UV emitters, and your choice of stars (12mm, 16mm, 20mm), and you can mod your own. Throw a 16 in any P90 drop-in, a 20 in a C8, etc., and you got your choice. Of course, pull as many 7135s as needed to keep from frying them, because I kinda doubt you can push 2.8A through them.
Do you know how long the coupon will be active? I want 2pcs but I am in red numbers
Hey mate till the 31st of December still have ages.
Good! Thanks
which one is stronger this one or the convoy ? already have the convoy so wonder…
The convoy
ok thanks, but u order from gearbest it then ?
You can buy a filter as well in simons shop
As the LED is overdriven with 700mA a better board might be nice
I’ve got the one from Simon and I got the zb2 lense too.
When I looked gearbest had 2 types, the Nichia one and the cheaper generic chip one that I don’t think is so good/bright, which one did you buy from gearbest.
The jetbeam is good, as it’s nice and portable on say a key chain, but the convoy is better for scaring people when you shine it round their bathroom/house
