Good or bad for a garage/shop? How many would I need for a 30x30 and
how much is a step up transformer?

I have three 400W fixtures lighting an 80x100 high-bay barn. *It would
be better with six, but it's adequate light to do auto repairs, as
long as I have a drop light for dark spots. (but heck, I need one even
in daylight).

I don't know how much a single transformer would cost, but it surely
would be less than replacing all the ballasts in all the lamps.

After finding out the cost of upgrading the ballast in an HPS lamp to
an HID type, it was more reasonable to pay the monster premium of
buying sodium ballast-compatible HID "conversion" lamps. *I've got
over 12 years of pretty regular nightly use on them (probably
10hrs/wk), and they still strike quickly and reliably in all
temperatures.

SO, maybe 3 HID's for a 30x30. I want alot of light, (But not alot of
heat.)

Can these be mounted to a wood truss/ceiling?
