Is there a source where I can buy a few deep UV leds?   I am taking
pictures of glass under UV light, and even with a Hoya UV(0) filter
(highest blocking available) the UV leds I have are getting through because
they are up at 395 where the filter still passes.  They show up as an
intense blue light in the camera. :(

I need to move the source down below 350nm so that the filter is more
effective.  I know they are made down to 260 ish, but I need some that I
can actually buy in onesies.
