Who likes wet roots and low light?

[Fishkeeper]

This is a Hygrolon living wall that I'm setting up to take with me to college. Hygrolon is an inert plastic mesh that wicks water and is perfect for growing plants in and moss on. I'm looking for orchids that will do well on it, and, as it's only 12" across, they need to be small plants.

Trouble is, the only lights allowed in the dorm are LED or CFL reading lights. The light currently over these is the brightest I could find to fit in a reading lamp. It's a 100W equivalent LED light that puts out 1680 lumens at 5000K, so it should be enough for at least some low-light plants. The lamp is about 8" away from the brightest point on the light, a spot just above the deer skull.

The bottom half of the wall stays damp constantly, a portion above that stays just slightly damp, and the top just about dries out between daily waterings. The deer skull can have things mounted on it, but it's coated in acrylic, so it'll function as an inert object and won't release anything, helpful or otherwise.

So, does anyone have any suggestions for small orchids that like to stay damp, don't need terribly bright lights, and aren't too picky about temperature or humidity?
