How is it that the spec 4 version only emmits 1200 lumens? I would expect at least twice that. I've heard that the stock version will drive the nichia 219bs at around 9 amps at the tail cap with a proper high drain 18650. Why is your driver driving them so low, that pretty much defeats the...
What's going on. I thought the XP-L was supposed to mbe the brightest Cree has at this point. Their website is claiming 220 LPW and max output of 1226 lm @ 10 W. I had high hopes for this die, but this is discouraging.
So I accidentally left my aw flat top 18650 in a change holder in my car and put an unopened water bottle over it because i had no where else to put it. a couple days later i look for my battery and it is sitting in a puddle of water. I look at it and there looks to be rust in the positive side...
I still think that the preon would be a super boss if in the future when 4sevens gets those xm leds. they should put them in there and then make it a 3 AAA light cause that would only be like a cm bigger then a pen (cause the 2 AAA preons are shorter than a pen). that would be the best pen light...
no, you would need much more amperage to do anything with an sst-90 compared to an mce or p7. even if you could get some imr cells in there and buck them the flashlight body wouldn't be able to handle the heat.
The G500 will be perfect when it comes out. its basically going to be a beefed up t20c2 r5. also i heard there might be some added bonuses such as maybe active thermal management or maybe the s2 bin.
I'm saying it is an inefficient design, for how big it already is if you put lithium batteries in it and an single head there would be much more room for a bigger heatsink and better reflectors. However, I don't know why i was so angry when i wrote that last comment and i do regret the tone that...
I think this light its just retarded, it was poorly designed just so that it will look weird. They could have made a single head with a reflector like the m2xc4 which would maximize its throw for the xpg leds. also this single head would allow for a bigger space for a heat sink which would allow...
I would wait for the quark g500, it is going to be beastly. Its going to be about 460 bulb lumens from and xp-g led so it should throw as far or farther than most xp-e, or xr-e leds with almost twice as many lumens. its going to be amazing.
