Isn't that around the time the westinghouse name started getting replaced? Or is this a Philips made bulb without the Lifeguard arc tube? Did they have two separate types of bulbs being produced?

As far as I know, this lamp is still basically a Westinghouse Lifeguard. Philips kept the lifeguard arc-tube for a period of time after switching from BT to ED lamps. I'm not sure exactly when the lifeguard arc-tube was dropped, but I think it was in the early nineties.

They dropped the Lifeguard arc-tube in 1995.

I don't think they dropped the lifeguard arc tubes all at once though. Some wattages remained undercover lifeguards for longer than others. IIRC the medium base lamps were the last to go in the mid-90s. The larger lamps were "de-lifeguarded" earlier I believe.

Please check out my newly-updated website! McCann Lighting Company is where my street light collection is displayed in detail.
