Review: Sky Ray 3800 3 x XM-L

Decided to simulate temperate conditions. The thaicpf tests were done in Thailand. Innocent

Temp was around 16 deg C, light breeze of about 5kph. That should be indicative of conditions of what some of you guys experience outdoors, even in dead night of summer.

Time 1 minute, 8 minutes, 19 minutes. 23:13hrs, 23:20, 23:31 as indicated on image EXIF data.

1351 -> 1324. Drop of 2% 19 minutes.

Wow. That's quite surprising... in an extremely good way.

I think that answers any concerns with thermal runaway.

Full bore runs from thaicpf. Last image is 54 minutes (!!) I am posting here as I think thaicpf went down, this was gotten from goggle cache, just in case the nice data gets lost. Pictures credit to brother dong of thaicpf. The diff between this and my test is that this is tropical temperatures kind of acid test, mine is 16 deg with a light breeze (I tested it directly under an air-conditioner airflow) which is more indicative of what you guys would get, probably even better cooling as I think you guys get cooler weather.

Light is regulated anyway, just for info Panasonic NCR18650 2900s were used.

This light have excellent heat sinking. The drop-in is secured to the head and

thus the body of the flashlight. The head gets very hot under use.

Sky Ray 3xT6 is pretty close to 1700 lumens OTF of the SR92.

Check out the animated GIF near the bottom. Check out the spill from the light direct from the emitters and not the reflectors, the lighting on the vertical pillar just beside the hotspot. SR92 and Sky Ray are nearly the same.

And the best thing is, the Sky Ray can operate as a shorty with 2 x 18500, Generic IMRs are only 8 bucks a pair on bestinone.net

I think that the SR92 is gonna throw a lot further.

Spill (or short distance) of the Sky Ray could be brighter

Don't have to think, it is without doubt that the SR92 is going to throw farther. Laughing There is another thread with an animated GIF fo the SR52 and SR92, the SR52 is a 60mm reflector XM-L U2, something like it will throw slightly better than say a Catapult V3. The SR92 in turn threw a bit better than the SR52, while also being brighter overall with bigger hotspot and stuff.

Hey bro, any beamshots and hotspot size measurements of your Trustfire X9? (or did i remember wrongly)

This JUST hit Kaidomain. :) Keepin' up with the Jonses.

[edit]
ah nevermind, it's not a clone, it has at least twice the "fins" for cooling on it, hmm... this TrustFire is really tempting me.

I know... got not much time lately.

Next days I will take a picture on the white wall, sorry for the delay

BTW, I think the Fenix TK70 might be a better thrower than the SR92, it has bigger triple reflectors.

Was planning to ordering one of the two, but I will wait until HJK both flashlights run a competition

Didn't someone on here order that one and it turned out to be less bright than the one from Manafont?

I'm not sure how they could have, I posted it here about an hour after it hit KD, if that. Not to mention, when you search the forum here, you get...

I guess I have it confused with something else. Thanks for the info!

Mine showed up today suddenly with no update from USPS so I was surprised.

I can't add any more than has already been said-it obliterates every other light I have with NO green in the tint at all. My tweaks were: Resoldering poor solder joints on the clickie and the spring on the driver, cleaning everything and making sure everything is nice and tight. Light came to me flickering and the tweaks fixed it.

Questions: Has anyone used 18650 IMR's? Not gonna be the guinea pig this time!

Also, I'd love to get a big glow ring for the head like in the UF-980L. Anyone know where I could find some?

My recommendation: Just go get it!! Wonderful light.

WOW I got mine today. Also got some new test leads.

Tailcap measurements

trustfire flames 3.15

soshine 3.13

samsung 2.98

xtar 4.1 OMG settled to 3.89 The xtars were not fully charged. Only 3.85 volt

Will top up all batteries and re test.

So in order to fully drive all 3 (before they start putting out a ton of heat), it would have to be drawing about 9 amps, assuming the driver was 100% efficient. So more like 12 amps from the tail. Or am I misunderstanding how the drivers work in these multi-LED lights?

Hmm... I can't wait for some lightbox readings of these various new ~$50 3x XM-L lights. Especially that new TrustFire I linked yesterday. My friend Lee ordered one yesterday, can't wait to find out how it is. I might have to order it before he gets it, simply to make sure I get it before it's sold out / backordered.

update:

2.8 A with freshly charged xtar 2600

You say it doesn't throw that good. Does this mean it really doesn't throw well at all or is it more because of the strong flood?

It'll throw ok, but not like a dedicated thrower. Basically like a really bright p60 xml drop in. IOW don't buy it for throw, but it'll make do if you ever need it.

This is pretty solid light all around. The only problem on mine was lens rattle.

The thing is, people would mistakenly think that 3x the XM-L means it should light up something really well even if its far away. But it does not. So we'd not wanna risk people condemning a good light just because "they are mistaken". As in.....Hey folks, I gotta say that this light is all hyped up and its not performing well for my copy. My Olight XP-G is better.

100m Beam shots :

Sky Ray 3 x T6. As you can see it lights up much more real estate, real good for < 100m usage.

Well I think most of the time i won't need to light up an area at more then 100m i think. The UF 980l is half the lumens of the sky ray if i'm not mistaking? So yes by that i know definely see that the throw is on a whole different level.
