We have received the new J4 sliver one from Mrlite company , and will ship one to Old4570 do a detail review tomorrow,and i also took some photo by myself !
Just get the notcie from The mrlite company ,the black one was temporarily out of stock,so if you ordered this light , it might need about a week when we shipped the order. the sliver in stock now .
If you want a customized mode , you must sent me an email( Daniel@lightake.com) contain which mode you want ,and your order number ,and i usually will reply you within one day.if you didn't sent me an email we won't sent the customized mode to you .
The MX4 and J4 are the same style , only use different battery.so you no need warry about the J4 can't work with AA battery .
OK, this light is looking really, really good. I just talked to Richard @ Mrlite, who is actually the designer of the J4. (Pretty cool eh?) He showed me the light over his webcam...
They got the modes worked out to our liking, including the 1 or 2 lumen moonlight mode. He says they measured the draw on the lowest mode and it's only 4ma, which he says should give at least 150 hours of runtime!!! In fact, according to my calculations, a 2000mah Eneloop should run for (2000 ÷ 4 = 500) hours, or more than 20 days! I forgot to ask him if the light is PWM controlled or not. The good news for all of us is that the driver accepts AA, unprotected 14500, or protected 14500 batteries. This is news to me; I thought we would have to choose between AA or 14500. The lens acronym that I couldn't remember was simply AR. The beamshots look good:
Newbie questions: Can we customize the modes ourselves by programming the light like an AKOray K106? Or do we have to get it done before it's shipped to us? How do you get moonlight mode?
Well I got one of the last black ones according to Daniel. It's going to be stock because I ordered it before I knew I could have custom modes. Oh well. I just have to figure out how to use the "2 modes with 9 types of output".
That flashlight uses a TIR optic, you see the BIG dot in the center of the lens? that is a TIR optic, which allows to concentrate the beam and throw farther...
It certainly looks like a TIR to me (Collimating lens).
The few I have give a very large hotspot and little to no spill. The hotspot also tends to be very circular - much more so than most reflectors, you can see this in the pics from MrLite.
Those modes need to be spaced out more. Best would be 180/60/20 (33%/10% pwm), which is nicely space. You want useful modes, and 145 is barely lower than 180 since human eye meansures logrithmically.
Also, can MrLight control for their emitter bin/tint and use WH/WG tints (~5000K) instead of WC (usually mean 7000K+ when from china)? Every person here who's gotten lights with these slightly warmer tints have loved them. On lithiums, 8000K is common with WC+ tints, and casts a terrible specular shade on everything, and also rather useless if there's any moisture in the air since it turns a slight fog completely white.

TIR because it's plastic lens can take on complex forms resulting in almost any type of beam you want, depending on how sophisticated your design is. :)
I just took a look at some TIR-optics at led-tech.de they are available in many beam angles. Wouldn't it be cool if we also could order custom beam angle? But maybe I'm asking for a bit too much.
If the head isn't glued - and that's a deal breaker for me, gluing it so it can't be disassembled - then it'd be easy to swap out the optics though most of those are quite wide angled.
But maybe I'm asking for a bit too much.
