Re: [DIYbio] Re: Need a UV light source, any designs for deuterium/xenon bulb power supplies out there?

Even from AliBaba 260 and 280nm LEDs are >$100. Seoul OptoDevices
manufactures 280nm LEDs as well, but they won't sell to anyone who
smells of U.S.A. because they have a dealer called SETI.

For $100s of dollars, we can definitely get a xenon/deuterium flash
lamp that would be small enough for my needs... if I ever get to
building a UV Raman spectrometer for some crazy DNA sequencing ideas I
have, and it works, then the LEDs would be an option to take such a
device to the ultra-portable level.

For now though, I need to design a flash lamp.

You can find these on
