My favorite setups bulb finally took a dump. But the kicker is , it was unmarked so I didnt know what it was but it was pretty nuts. I want to say it was 350-400 lumens on 2x16650 cells. 8.4V What are some bulb replacement choices for the M4 bezel ?

Have you tried Lumens Factory?
I haven't looked lately. I was poking through my light draw and found a TAD G4 socket from my old M6 so I have that option for bulbs too. Need to see if anything is available in the voltage range.

LF has a few options. 9V sligjtly underdriven I guess or whats that IMR 7.4V deal? Can that run on 8.4V ? Why does it say IMR only? Interesting and that would be pretty nutso at 700 lumens. Im sure some wacko here has tried it...😂😂

Pair of protected 16650 (2500mAh) will power up an WA1274 safely and bright with good run time.
When current of bulb is relatively high, IMR will serve better.
BTW, you can count on 7.2~7.4 volt on pair of 16650 under current of 2.5~3 Amps. 8.4 volt is when fully recharged and no load.
