New HPS NEMA head

This NEMA head was installed just a few weeks ago. It replaced an old (I'm guessing 1970's) merc NEMA head that had been non-functional for many years. It had no lens, just the metal reflector and merc bulb, but did not work for many years. I reported it and a few weeks later, this brand new HPS NEMA head had been installed. Very bright too, must be at least 100w or even 150w. I think it also has a closed or vented bottom lens (it was easier to tell when it was lit).
