Yeah, I suppose it's NOS. So were the silver 4D incans I bought, but they were all outfitted with bi-pin bulbs if that means anything. Easy enough to convert to PR (krypton) if the bi-pin takes collector points off.
I've yet to put a battery in the blue one. Not sure what I've got in mind so it's stashed with my 40th anniversary light.
I bought 4D xenon lights when watching the tv show Jerico on video, and after an EMP murdered all electronics in Kansas some used 4D Maglites.
