I am looking to replace a burned out lamppost light. The currently installed lights are 75-watt GE "postlight" "saf-t-gard" (teflon-coated) bulbs with a medium (E26) base and "E17" shape.
Unfortunately, it looks like these exact bulbs are not made anymore. GE has even reused the same part #90839 for some kind of miniature holiday lights. I found a listing for the original bulbs on Singaporean Amazon (2) , but it's out of stock (and I am in the U.S. anyways).
I have been trying to find a suitable replacement, but when searching for "E17", I only get results for the E17 base -- which is too small, since these bulbs use a standard E26 "medium" base.
Ideally, I'd replace these with 2700K LEDs (75W or 100W equivalent), but at this point, I'll settle for finding the right shape of incandescent (with or without the teflon coating). I have two lampposts and two wall-mounted lamps which all use this same bulb, and it would be expensive to retrofit different lamps altogether.
What is the correct shape to look up for this "E17" bulb? I can't even find it listed in GE's own list of bulb shapes. I see ED17 bulbs, but they seem to only be metal halide or sodium and require a ballast, so I am not sure if there's a different code for incandescent/LED bulbs of this shape.
