So these are probably not good to use in a garage/shop?

Why? *We were talking about heat per lumen. *As far as I know, sodium

The quartz envelopes are not exposed -- they're contained in an outer

You want lots of light. *You'll have to virtually cover the ceiling

The height from my floor to the bottom of the truss is 10 feet, 4
inches. I have no ceiling currently, so I guess I could mount them
even higher up on the truss.

I dont think these are low bay lights.

I guess I was not sure if the actual housing could be mounted on wood
or not. I was not sure how hot the housing would get.

Are these the type of lights that takes awhile to get bright when you
first turn them on or loose power? Are they expensive to operate?

I appreciate your help. I am not real familar with these.

I have a picture of the inside of my garage/shop if it helps anyone.
