I took it outside to check out the beam profile and slicing the dome made all the difference… no dark spot in the center at all. I can see black cows out at about 200-225 yds laying in the dark grass. Not bad at all.
Why exactly should I have to wait around and time my presses so precisely? I turn my L6 on, it’s on low, I want it to be on turbo, three presses is all it should take. Inevitably, however, I’m treated to amateur discotheque hour.
The copper mcpcb is among the thickest I’ve seen, looks to be about half again thicker than an MaxToch. So that is good. The small finned section where the switch is just so happens to be exactly where the heat is going. Also good. I didn’t get a read on how thick the emitter shelf is, but when I took it outside it was warming up but didn’t get hot in the few minutes I had it on before the bugs discovered the light. (It’s June Bug season here, big fat whoppers slamming into everything. Lousy flyers.)
I’ll get a better idea how it takes the power this weekend.
My beam shot alley is totally screwed. My Dad’s brother bought a 5th wheel trailer and decided it’s too big for him, so Dad let him park it out here while he tries to sell it. Dang thing is 34’ long and 13’ high! Of course, he parked it right smack in the middle of my side yard where I shoot beam shots. UGH! I need to look and see if I can shoot a hot spot past it, the big white trailer will sure show up in the night though. lol
Edit: Beamshot alley is clear, the trailer is North of where I need to shine by enough of a margin. Lightning tells me to wait til tomorrow night…
Tom, the X9 will surprise you… it’s got good power but it’s silly lightweight, like it makes you think it doesn’t have cells in it when you pick it up. About to use mine to walk the trash can down to the road for morning pick-up. Even my wife asked me if it had batteries in it the first time she used it.
When this X9 will be lower in price iit will be a real concern for the L6/S70S.
Lightweight, classy design and same lumens (but less throw, but neither L6 and S70S are thrower so…)
The X9 just so happened to show up today! Wow, it feels so small in a way. Thermally it's an odd design - no fins, thin body where mass and fins are needed the most. Also some sharp edges on the SS bezel, but the thin design makes it an easy carry for a 2 cell bigger style light.
The box is very well padded,light seems in exc. condition
It's very comfortable in the hand because you are not holding a massive head light where the switch is. It's somewhat wasteful in length but comfortable to hold. I gotta get it setup with cells and play some.
Guys, you mind sharing some pics with us ?
I’m interested with this one and would want to put things in perspective with, say, some other known models maybe ?
I find flashlights in hand pictures really useful too
Sorry no pics yet. I ordered the N4 3C, but it's hard to believe it's an N4 bin, but the tint looks to be a great NW - milky white consistent tint through all zones of the beam.
Tail amps on LK 5000 cells: 4.7A, lumens: 2,850 @start, 2,770 @30 secs, 36 kcd (380m) measured at 5 m
This is well under the 3,800 lumens rating. I'm not familiar enough with what 4.7A should get you with an N4 bin, but for it to be 73% in my testing of what it's rated is pretty far off. For example, last night, along with the X9 I measured Lumintop SD26 and SDMini lights and both measured higher than their ratings: ~1,060 lumens on each with both rated at 1,000 lumens.
So if the info posted by Richard is correct, there is a N4 3C. I know NW's can measure lower than CW's on our cheapo light meters, but for 5000K, mine has measured top output levels in the BLF Q8's for example 3D tint in both XM-L2's and XPL's.
I'm thinking it's not a true N4 though. But again, would love to know what others are seeing on XHP70's and at what amps.
So at 4.5A, it does ~3,400 lumens naked, so allow 10%-20% optics drop, for 20% it's 2,720 lumens - right smack dab in the ballpark.
Some explanations:
I'm using 4.5A and not 4.7A because I measured with the tail cap removed using a reliable clamp meter. Tail cap may add resistance.
20% may be a bit high for the reflector and glass, but again, in the ballpark
I'm thinking the NW XHP70 is an N2 bin and not N4 based on this quick & dirty analysis.
So maybe the CW is a true N4 so will be bumped and maybe I'm getting somewhat lower amps for whatever reason, or maybe the 3,800 is a bit optimistic. Thinking Dale has a CW so hoping he can post his numbers. Our PVC light boxes are very close to the same calibration from past experiences.
For me I still really like this design and the light - it sure is a compact 2 26650 cell light, and can certainly double for a pretty effective weapon with the thick and somewhat sharp SS bezel. If I want more power, easy enough to do, and could replace the LED if I want. I'd probably not do resistor modding but prefer to do driver replacement - NarsilM of course.
