Is it exposed joists?
I'd just hang whatever cheap recessed can fixtures were handy, and stick standard A19/E26-sized LED bulbs, maybe directional floods, in them.
The LED game is changing so quickly I'd be loath to invest any big bucks right now, but would still want the electrical savings.
They also sell T-8 fluorescent tube shaped compatible LED's that will fit in a regular fluorescent fixture, or those cheap chain-hanging shop fixtures.
