To me, an older bulb would be at least a BT37.

Proudy suffering from "Westinghouse Lifeguard Disease" since 1977! :lol:
There's no known cure for Westinghouse Lifeguard disease, so the only way to treat it is to find more!!! :lol: :lol: :lol:
Real HID lamps contain Hg! ;D

On the base you can find the date code, it will start with the letter r . The code should contain 2 letters followed by 3 numbers. Someone here should be able to give you the date of manufacture. I'd guess it's late 90's or newer .

That's 2003 or later based on the Hg label. Not really very old.

I like my lamps thick, my ballasts heavy, and my fixtures tough.
