How to make a photo-reactor?

Tools
1

I am interested in making a photo-reactor (for 8 mL vials). Here is some information I have already thought about:

  1. Fairly high power is required to induce reactions (~1W or greater)
  2. A high power LED requires control that accomodates higher current
  3. High power LEDs are usually single wavelength, RGB LEDs are weak and white LEDs inconsistent
  4. High power LEDs may produce heat that needs to be dissipated

So - if I want photo-reactors to promote crosslinking or chemical reaction, is the way to go to make a single reactor for each wavelength? What control would you use (eg to hook up to a Raspberry Pi)? What LED? How have other people thought about these various constraints to design flexible photo-reactors?

Maybe the Wisconsin Photoreactor Platform [manuscript] could be a relevant resource? (I came across this solution via the GOSH forum)

I love their design! I think this is a good starting point
