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).
The leather shop where I spend 2 afternoons a week just completely
re-did the factory and warehouse with LEDs replacing high pressure
vapout and flourescent lights - and last week replaced the high
pressure sodium lighting in the parking area with LEDs as well. They
couldn't be happier. It will take 10 years to pay for the re-lamp with
power savings at todays prices - but take off the cost of replacing
failed ballasts and bulbs, and it looks a LOT more attractive..

300,000 sq ft, high ceiling production area (task lighting) and
warehouse.

Reduced A/C costs as well in many cases. LEDs aren't heat free, but they
certainly produce less than HID fixtures and many fluro fixtures.
