supplier of H-3 light sources

[tracyjw@nist.gov]

I have a researcher who is looking to purchase some H-3 light sources.  He currently has a set 

that consists of rods, disks, and spheres.  They come with different phospors to produce 

different colored light sources.  He is looking to purchase something similar.  The original 

supplier was a company called Betalight.

Are these are still manufactured?  Does anyone know of any suppliers of this type of product?
