Anyone used 'em?

I've got a high-bay shop with about a dozen 8' florescent fixtures, only
a few of which work. I'm thinking of replacing them one-by-one with
these things, whenever the planets align and I'm extra flush with cash:

The alternatives are to buy a bunch of ballasts and continue to mess with
fluorescents (and tubes that are now considered toxic waste, omigod), or
mount light sockets onto 2x6's and put in screw-in LED bulbs (which is
about $50 per fixture cheaper for the same light, but labor-intensive).

I've recently had good results with the 65W CFL floodlight fixtures that
'Depot sells. Mounted at 18' on opposing sides of a 50'x50' area in a
metal building (white insulation facing) just four of them provide good
overall illumination for general work. Eight of them would be really
good. They are only $50 and include the lamp.
