Interest list for 41.8mmx2mm ZWB2 filters, status: produced, received and most filters sent to BLF-members

Will keep that in mind. I ordered them anyway so there is plenty time now to get the last spots filled up.

Now I just hope that during shipping from China to me no extra costs are generated underway. :innocent:

Great news. Please let us know what we owe you when you have them in hand. Thanks again djozz.

I’m just building a light around your filter… :sunglasses:
For long I thought about toying with an UV light but never did. The idea of blocking the straylight just put me over the edge. Now I ordered a Sofirn C8F host and 3 emitter (went with the Seoul Viosys after your great UV-LED test).
Funds are standing by, just gimme the word.

That’s funny Harley, I had the exact same thought but haven’t ordered the light yet. :smiley:

Edit: I was thinking more of a Nichia emitter but… :wink:

We are all building the same light, the C8F with the Seoel Viosys led (good output, small die) :cool:

I have one Lexel Narsil driver leftover that I can use, direct drive will hopefully get the leds close to 2A per led.

Let’s hope that Changchun Ruiqi Optoelectronics (that is where I did the order) is a bit quick with making them.

Btw, there’s still 2 spots vacant in the list. Anyone?

If nobody else needs one, you can put me down for a second one.

Is anyone in need of up to 6 Watts of 365nm light in a throwy flashlight? :party:

If no other else signs up for one, the last two go to you and Dale.

I would like to obtain 1 filter, if I’m not stepping on anyone’s toes.

^ added :slight_smile:

:weary:
Ok, so I have put $230 in getting 20 of these made and guess what? Kaidomain comes up with a series of different sizes ZWB2 filters, among which a 42mm one. Great news but very bad timing for my group buy, it would have saved me big time if they had listed them two weeks earlier (in money and effort).

A slight difference is that KD’s filter is 1.5mm thick, as opposed to 2mm for mine.

I can understand if people want to back out on this group buy and buy the easier and cheaper one from KD, if so please let me know.

Know offhand if the C8 glass is 1.5mm or 2.0mm? I’d rather not have the front glass rattling around… :smiley:

I’m in absolutely no hurry to do anything with them (seriously, not for a month or more), so if anyone else wants in, or wants them in a hurry, he/she/it can take my place, else I’ll be happy to just sit tight.

9bux vs 14bux, I’m not exactly gonna have to eat ramen for a month…

I’m still in and will probably hit you up for a few of those s2+ gaskets at the same time. :slight_smile:

I am still in too.

I have 2 Convoy C8’s, the lenses are resp. 1.8 and 1.85 mm thick. An Ultrafire C8 that I have has a 2.1mm lens.

Okay, so not bad then. And I imagine the O-ring would take up at least some slack…

So, still in, but make me a low-priority. If anyone wants one, they can take my place. I’m busy playing with some RPi0Ws… :smiley:

No way would I back out after you have did this work and spent your money. Still in here too.

Still in. And appreciative of your efforts getting the BETTER materials. :slight_smile:

Just looked at past messages. It was korpzgrinda who was looking for one, and he’s on the list, so never mind. :innocent:

Didn’t recall who was asking for one, and didn’t know if there were any left. Well now I do. :smiley:

Still in.
