I've ordered the adjustable aluminum mounting brackets for the TrueLumens, which are for a 60-P. I'm curious to see whether they can be adjusted/bent enough to make the 12" version work on the Mini M. If so, then that's the way to go, both in terms of light and aesthetics.
I also ordered a couple 16" Finnex Ray II lamps. Their arms are supposed to be adjustable too, so I'll let you know how that turns out.
