They are directional from left to right in the pic. So they can be parallel to the road and just light up the parking lot.
The diodes are big but not huge. The aluminum reflector makes them loose bigger. iirc they are 245 watts. Can't remember but I knew when I was figuring out how many could be run on a circuit and what gauge wire to run.
When I put the ones up at this next store I'll take a close up pic. Still bending lots of pipe inside right now.
