I've wondered what brand these wall packs may be. Sorry the photos aren't the best, I had to get them from backgrounds of some pictures.

The ones on the right in the silver color are on the older buildings build in 1970, and they are mercury vapor. Some have been replaced with HPS wallpacks. I'm thinking they might be Holophane, they looks similar to the incandescent versions seen on eBay. They have a frosted glass that's a bit hard to see.

Now the ones on the left in the bronze are on newer parts of the school from 1989. These are HPS. Some of these also replaced with wall packs. I have no idea the brand of these but I really like them. They have a curved bowl shaped lens with a metal guard over it.

Sorry, pictures way too small to identify anything, certainly with my eyesight

I understand. I couldn't take pictures myself at this point, but hopefully get a chance in the future. Plus I'm probably removing the thread, until I get better photos. 

The one in the left, in the back, looks like it could be one of these.  There are versions of this style fixture which have a grill over the lens.
