Really? I never knew how rare 150w HPS was!

Well, there is Puyallup; there are quite a few 150W luminaires there, but that's pretty much it. New York City, on the other hand, was loaded with custom-made Cooper OVZs that were 150W.

I'm not sure why to be honest. Near me, I knew of only city that used 50w HPS street lights with that city being Montclair. Montclair is now LED, with the exception of the intersections for right now.

The 150w HPS street lights were actually somewhat common here. Before the LED changeouts, I've seen a good amount of 150w HPS lights in use in a lot of cities.

Columbus OH and the surrounding area is packed full of 150w HPS on most of the smaller roads . Larger roads are 200 , 250 , 310 HPS .
