4 more 365nm UV-leds tested

Already got the quote in for 20 pieces of 2mmx40mm ZWB2 filter (fitting the C8), And I’m a bit double about it. They cost $9.50 each, with 50 dollar shipping. So that is an investment of $240 dollar which is not nice (I hoped for under 100).

On the other hand, if I could buy them for 12 dollar plus shipping (which is just $1.80 from my place to worldwide), I would buy 2 of them without hesitation.

So if I know beforehand that I would sell 17 of the 20 pieces, I would do it, but I doubt that there’s interest for 17 ?

Edit: I started an interest list:
