Hhmm, the MT07 is quite low but it is NW, not CW. Mine is doing 5,300 now w/resistor mod, but was 4,700 stock. Still 3,500 you got is quite a bit lower than the 4,500 they rated. Wonder if the 4S is lower lumens...
Disappointed to hear another MT07 NW at ~3500 lumen like mhalen’s (his was 2s2p if I recall correctly). I know NW is lower lumens but I wouldn’t expect almost 1,000+ lumens less. None of my other NW lights have this much of a difference. Did Haikelite ever officially release lumen ratings for the NW?
Yeah mine was 2S2P. They told me they would send me a 4s driver. They said that the battery tube is the same, just the driver is different. I don’t want to sound like I’m glad that unknown got 3500, but it at least confirms that I’m not the only one with a NW that got that. I’d be curious what others are getting too.
I didn’t think they could add a 4s driver without a change in battery tube. Unless the driver has wide operating voltage range. But then why would a 4s make sense without a change in the battery tube. I dunno. My battery tube is definitely side by side and not diagonal.
My MT07 NW is getting 3560 and my MT03 NW is getting 6750
how can I tell if my lights are 2P2S or 4S
I also have some strange dents on the neg side of some new VTC6 cells—I don’t recall them being there—not sure if dogging the tail cap all the way caused this—crazy
It may be the springs. My cells have some marks after a few swaps too.
The 2s2p is on the left, 4S on right.
My threads are absolutely marred up from presumably dull machining tools. Poor QC.
This is after a thorough cleaning. They were perhaps the dirtiest threads I’ve come across. The MT07 threads had small particles of dirt/metal that were grinding upon initial opening.

Also I got around to testing my freshly charged 30Q set.
4.197v off the charger.
MT03 2S2P NW 7285lm at 30sec.
MT07 4S NW 3610lm at 30sec.
So a fair bump for the MT03. There’s an odd drop in those initial 30 seconds. It slowly decreases from about 7700lm at turn on down to 7630lm at 20sec, but suddenly drops about 350lm around 24 seconds.
Received both 03 & 07 4S lights today, bought 8 batteries with order and got 4 so doing pretty good,
Thanks Pok Tom E for heads up on the screw, mine is missing also, thread anodizing is bad on cap ends of both the 03 and 07 similar to pics above, pos and neg soldering jobs are not the best, perhaps the worst I’ve ever seen on a new high dollar lights, hum…
Batteries arrived at 3.44v, so it will take 3 hrs to charge and I will have to test lights tomorrow, thanks all for the heads up,
I have to say I am a bit surprised by some of what I am seeing and reading with these lights, sure am glad there is the BLF.
Well Haikelite did ask me if I could tell what color temperature exactly my MT07 NW was… Maybe they thought it was an emitter. I don’t really know, but its seems the first three people capable of measuring the NW are getting all around the same numbers. It seems like this does not affect the MT03. I am not sure if the NW version of those is using the same emitters.
