I can do blue excitation light. But i would like to see the red autoflorescence of vegetal stuff.
I use a RGB LED torch that works wonderfully but i have two diferent position for the cube filter and i think that none of them allows for that. Should i try to change the filters in the cube?
I think blue and Green excitation are the most common.

For effective plant autofluorescence one needs to excite at 400-430nm (that is violet, not blue), cutoff (dichroic mirror) around 500nm, end an emission filter that transmits above 550-600nm.

Were you able to work this out? I know that UV flashlights often contain some violet in them if you're looking for an inexpensive light source. Though you definitely will want some filtering in place. I've never seen a violet-specific flashlight in a hardware store, but the UV ones are really common.
