my partner and I are currently researching mushrooms as a source of vitamin D for our 23 month old son. He has been diagnosed as vitamin D deficient, and it is winter here at the moment. We are wanting to try out putting harvested mushrooms under uv light as a source of vitamin D for our son. We are needing to know what the name of the specific UV lighting that is being used, and if these are accessible to the public consumer?

Hoping somebody out there can steer us in the right direction :-) thank you
