How many / what kind of LED's would be good for a low light 20G High.

I like the idea of having some of that nice ripple effect, but at the same time I don't want stems all growing towards the middle or something.

Would 6 XM-L's on a 10"x10" heatsink work? I'd probably under drive them around 400mA.
Seems like it might be too bright.
It'd have to be passively cooled too I can't stomach the idea of a fan.
