> five for $5
Beats the two for $20 that was the going price on AliExpress a few weeks ago.
I received my 5 pack today and as indicated by djozz in his test, the filter is very effective with the 3535 led.
Waiting for the Nichia S2+ now.
What wavelength are you using it with? I’m still waiting on my five-pack. I have two lights, a 365nm and a 395-400nm, and I’m looking forward to trying the filter on both.
The 3535 is 365nm but according to djozz test its peak wavelenght is at 470nm.
The zwb2 will only work effectively close at 365-370nm, at 400nm it will just block most of your 400nm light, while not removing white light because 400nm leds do not emit the white light.
Bump (with hat tip to Sharpie) as a reminder these are still for sale out there:

Any 10mm ZWB2 cheap source ? (I mean…not 9$ for two pieces)
Nope.
From how cheap GB can sell the 20mm ones, they cost next to nothing to make. But there’s only one or two sellers on Aliexpress (the Ebay-seller is the same as one of the Aliexpress sellers), and they can and will ask anything. I would be interested in a 12mm diameter version because they fit in most AAA-lights, but I have not seen it anywhere.
Perhaps contacting a manufacturer on Alibaba is a route to go, there is many sources for ZWB2 filters there.
Yes, their prices are way too high for what it is…
I just want to do a BLF348 UV light with ZWB2 glass.
I have two 20mm ones from Simon that I hope to be able to reduce to 10mm like CRX did.
I know that I’m far to have his skills so I’m a bit stressed to try… that’s why I ordered two :person_facepalming:
I’ll let you know how it’s going…
Be careful with glass-dust -> not healthy!
Sorry to bump a very old thread that apparently died aborning.
