I realy like that style arm too I would have gotten one myself but they were way too expensive. I believe it's a Hapco arm.

Yep, the arm is really the reason I took a pic of this one...it just looks good

I like that arm too! BTW, this is a 1980s-ish GE M-250R2. It's probably not 250W though since it has a plastic lens. Could be a lineman error though and a plastic was put in by mistake...

Thanks for the info.
I don't remember for sure on this, but am pretty sure it had a 250W NEMA tag..if I'm back in that area again, I do plan to double check that LOL

It very well could have been 250W HPS. Ian has mentioned the electric company likes to use plastic replacement lenes with medium wattage lights...

Lil'Cinnamon is Ian right? (sorry, but know you guys more by your usernames LOL).
He deff knows more about streetlights than I do (I really am more into Xmas-lights & Fluorescents .. its only in the past couple years that I started truly paying attention to streetlights)

From what I've noticed 250W HPS seems to be really common here on city streets..

Yep Lil'Cinnamon is Ian. (I'm Mike if you want to call me that).

cool.. thanks
