When look on the reflector, it's design correspond more to frosted lamp with large light aperture size and not for clear, spot-like (or narrow rod-like) lamps...
On HPS the coating is only to diffuse the light, so it is used only in very thin layer on pupose, so they normally look as "faded off" even when new...
I got it from the streetlighting contractor that services the lights here, I talked to the head if the streetlighting department and he eventually got this for me, I wanted a 400 watt fixture at the time (preferable working) and eventually they took this down. He delivered it right to my house.
My area is just as bad too, we have some lights that are dead for over a year but they go a replace working Powerlites (or at most needed a new ignitor) instead.
I wish Xcel would do that. xD But they don't give lights away.
I did talk to a guy at WL contractors, (Where I got the 113 (at Tony's place now), OVM, Tudor, and M-250 R1 FCO) and he said next time they do a huge cleanout of their yard, he would call me or leave a message and let me come over there and let me take what I can.
They have lots of goodies there too, Traffic signals as well.
I wouldn't count on them calling, there is another contractor I visited 3 times, they said they would have a cleanup soon and would give be a call, that was more than two years ago... Here they often replace lights that are cycling, sometimes even lights that are working.
They might. He said they do Cleanups once a year. But people do forget to do things sometimes.
He was still nice to give me 4 Lights from their yard because he knew that nothing would happen to them except for them being scrapped. Especially that Tudor because that is a rare thing, especially here.
One thing to keep in mind when askign for lights is don't mention that a light is rare or really old or they may get the idea to take advantage of you. National Grid services lines as far away as New York, and their streetlight heaven isn't in RI. RIDOT's used cobraheads (M-250R2, M-400R2, OVS, OVM, current M-400, OVF, and possibly others) as well as traffic signals, are all in one lot about 4-5 miles from my house. There's no doubt in my mind that my parents wouldn't take me. ( ) Maybe once I get my permit in a few years I can get some goodies there.
Don't get your hopes up. At first he wouldn't give them to me (a week before I got then) He said I couldn't have them because of the Mercury in the lamps. But then I came back and he let me have a couple because he trusted me and knew bad things would only happen to the lights sooo.
