Has anyone found suitable LED lights for their workshop? I have been looking but haven't found quite what I need.

I need some surface mount lights to fix to my shop ceiling. One complication is that I have 6"x14" beams supporting the second story crossing the shop ceiling every four feet. The bottom of the beams are 9' high with the ceiling (tongue and groove flooring) another 13" above the bottom of the beams.

I don't want to fix the lights to the beams as they are an aesthetic feature of the shop (#1 Doug fir shaped and finished) so the lights need to mount to the ceiling and have about a 120 degree arc of light. High bay fixtures that hang from the ceiling are the best I've found so far (2'x1' fixture providing 11,500 lumens - about the same as a 4 bulb t5 fluorescent fixture but about 5 times the cost.)

Any experience, ideas, suggestions?

Thanks.
