EAGLE EYE X9 XHP70LED inside Hard Light flashlight 26650/18650 3800LM

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…

My X9 is still help up in shipping, though there's hope it may come soon. The Mission M12 was also held up but finally showed up in NY yesterday.

That bezel looks like it restricts the width of the reflector - can't really tell though from the pics.

Mine was the last ordered bout 4 weeks ago - not selling crazy, for sure - must be my kind of light!

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

Interesting light isn’t it Tom? Lightweight, but still it seems to put quite a lot of light out the front and is pretty easy to handle.

Have been curious what your thoughts on this one would be…

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.

Those are bad news… What does EagleEye have to say about that ?

Usually the NW are noticably not as bright as the CW. I didn’t even know Cree offered a N4 3C. The highest I remember seeing was N2.

I believe EE only rates the CW version at 3800 lumen.

Even the CW N4 versions need more than 4.7 amp to get 3800 lumen. Closer to 5.25-5.5 amp is needed.

I guess it’s time to see if it can be resistor modded.

It's right here: http://www.mtnelectronics.com/index.php?route=product/product&path=60_114&product_id=597

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.

I tend to go by the cree data sheets. It’s the 4500k and below that only get up to N2. My bad.

If the driver is only capable of 4.8 amps, then I wonder why Eagle Eye rated the lumens at 3800? That’s a bit optimistic.

Have you looked at the driver yet? Does it look like it can be modded?

Djozz has plotted the xhp70 output so that gives you a good idea how many amps you need to get a certain lumen output.

djozz test of an N2 CW is here: https://budgetlightforum.com/t/-/30860/576

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.

Would you compare it to a 2*D maglite in terms of physical dimensions ?

He already did. See post 39.

I got 4.84A for 3212 lumens out the front, using a pair of Efest 18650’s. Have yet to test it with LiitoKala 5000mAh cells.

Edit: Okay, so I just got done (9:50AM 5-10-17) charging and testing two pairs of 26650’s, Efest 4200mA and LiitoKala 5000mA. I have sliced the dome on my XHP-70 in the X9, that said, on the Efest cells I got 4.32A for 3084.3 lumens and on the LiitoKala cells I got 4.30A for 3015.3 lumens. Two different 365nm UV lights show this XHP-70 in the NW range.

Oh dang, forgot or missed your #'s posted (my bad). You should be able to see in your Ali order history what tint was ordered. On mine in the order history summary it says "Product properties: N43C".

The CW option is N41A. The differences is interesting - could be in the realm of one bin difference, though amps is slightly different.

I didn't measure amps at each mode but did measure lumens:

lo: 29 lumens, med: 561 lumens, hi: 1,309 lumens

So I'm lower across the board, consistent with a lower binned LED, or consistent lower amps... Boy, hard to tell though but still I think we measure with our PVC light boxes pretty close.

Yep, my AliExpress order history shows N41A.

Of interest, I’m using an XTAR Rocket charger (SV2) with 2 bays and 2A charge rate capability. It seems that when using the 2A rate the cells don’t really get topped off properly. So I charged the LiitoKala’s again at 1A and tried them in my Convoy L6 with ramping firmware on an FET driver.

At 2A rate they did 11.21A for 6610.2 lumens
At 1A rate they did 11.98A for 6796.5 lumens

So this charger has different performance when using the higher 2A rate to charge 26650’s.
