drop me a email with "dead battery" on email subject to [email protected]
I'm waiting for these CR1616 battery replacements for this mailing-caused problem and gonna mail you guys with dead battery replacement.
Shorter Wavelength from CREE:
It's possible to make wavelength from 391-393 LEDs with more narrow angle in our manufacturer. Example: make a Bullet shape 5mm LED with well filtered CREE UV LED chips. The bullet shape LED makes it posible to produce LEDs with the half-angle of 7-8degree and to actually pick chips in 391-393 from CREE will make the most brightness(narrowest angle) and most useful UV LED(shorter wavelength). However, the counter part is more expensive(I don't know how many % up, but it'll be).
The most narrowest half-angle for 5mm Round LEDs from WILYCON are around 12 which make the viewing angle of 12x2=24 degree.
To Gransee: the 400nm LED you got is not Made by CREE, it's made in USA however
3mm:
I'm preparing the 3mm UV LEDs, any one interested?
