Review: Sky Ray 3800 3 x XM-L

I am looking forward to being able to pull the trigger on this puppy!

I said it before that this is a great light. Has to be about the best bargain out there. The only glitch I have is that sometimes it will snap out of low. All of a sudden it will go to full brightness. Not a big deal but that can be a real jolt depending on what you were doing on low mode.

The reason why I didn't order one yet is the heat sinking... It's still the drop-in design, isn't it?

~20W with a drop-in - I'm not convinced.

+1, count me in for the same reason.

You guys haven't been following the developments. So many measurements and real world tests (and its really a lot) have taken place not only here but elsewhere.... This puppy in this regard is even better than many of the high-end branded lights.

+1

+2; lots of good info on this light accross a number of boards. It's well worth actually reading through all the helpful info already provided before jumping to conclusions.. There is a reason this light has been so popular.

This use some kind of drop-in. The difference between this and P60 drop-ins it that this one is screwed to the head so heat transfer is better. P60 drop-ins are floating inside the host without good contact.

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!
