i got a fixture that needs a cap but i cant get up on ladders due to tunnel vision so i cant get it to work right now but soon it should be fixed its up real high on top of my garage fixture is from 1967
The “wrapped frame” lifeguards were a cost cutting move during the peak of the adoption of these in cheap yard blaster fixtures for residential use. ONLY the 175 watt lamps has this frame. The 250 watt version was still full frame, and was in the same BT-28 glass. These are good lamps, but those wrapped frames are crap and typical of the infiltration of crappy Philips when they bought out Westinghouse in the early 1980’s. It was a bean counter move and stupid. The later ED-28 shape versions by Philips were even worse! Weak frames with weak tack welds, no arc tube support straps, or wrapping the frame around the arc tube pinch seals, and TINY electrodes that blackened the arc tube fast and caused early failure. Utter crap!! The phosphor coated /DX and also /N Style tone lamps in 175 watt also used the crummy wrapped frame as well, starting around 1982-83. Cheers!

March 1982. Made in Bath, NY.

Me too
Were these used in city light poles for street lighting.
A look into NEC over head clearances might be a good thing, mercury vapor radiation is a real thing.
