Excellent!:thumbsup:
I'm in.
For a 730 nm. source, it's hard to beat Incandescent "black lights"
They put out a tiny bit of UVa and a relatively enormous amount of Far red.
They are cheap and available from Wallyworld.
Note that they emit considerable IR as well and the bulb gets very hot.
Might require more cooling.

Aloha and mahalo,
