Thrower - Flooder Beamshots (UPDATED - Now 34 Lights - Very Photo Heavy)

Awesome job, again!!

Great set of lights, very nice photos! There’s some serious effort represented there, on y’all part as well as others, well done. :wink:

Can I suggest maybe adding a link or two to the OP? First, a link to the last testing session would help to find what you refer to as being updated. If that link doesn’t have the table with data, that would be another link that would be great to add.

Heh, that XPG2 C8 caught my also. Is there a thread somewhere on that XPG2 C8?

Well I linked the older thread with this page. There is nothing on the old page that’s not covered here. I tried to update that thread but it didn’t list with new info or post. I guess now that I think about it I should have just “bumped” the old thread. But I was not thinking.
As for the XPG2 C8 - we don’t really have any special threads on it. It’s brothers light that Tom E worked his usual magic on. Is there specific info you are wondering about it? I’m sure either I, Tom, or manxbuggy1 can help on any details if needed.

Updated first post with dates when all shots were taken.

Nothing too special. XPG type reflector, XP-G2 R5 de-domed on 20mm copper (Noctigon I believe), Nanjg with stacked chips, thinking maybe 3.5A or 3.85A, 22 gauge wires, copper added in the pill, and running a hot cell like the Samsung 20R. I know at the time, I can't seem to get hiigh amps out of a single cell with a XP-G2 de-domed. Believe I saw that in this light and my Convoy C8 (same setup, same results), and with a UF T20 - maybe 2 of them I did.

Nice shots ! im guessing the Kung i have must be a good one as it beats out all my other kings in throw and flood stock, and the one your showing seems dimmer and weaker than the others.

Yes either your Kung is strong or your Kings are weak because stock both rdr’s U2 and my T6 king beat his Kung in both lumens and throw. After Dale (DMCstm) got through with it, it’s a different story. It is a beast. So is the the King he modded though.

I think my Kungs main issue was its very pathetic wires. The kings were bad too though, but perhaps trying to get power to all 4 emitters it just couldn’t handle it. The wires were 32g at best.
But now both lights are great. Both tested consist before and after modding - King is & was more powerful in lumens and throw, but the Kung is superior in being a floody little beast. The other interesting tidbit is my King is a non Torroid driver, but the Kung has one. So the drivers arn’t as critical as most have claimed.
I’m sure the sellers of these lights greatly vary in their construction. Different wiring, different LED’s, and better or worse assembly. So kings and Kungs are always a crap shoot on how they do. If any of them are tweaked with better wiring, LEDs, and thermal paste, they will perform nicely.
I also found out in testing last night that even these little kings with 4 cells are picky about better cells. I’ve been running some “ok” 2500mah protected Eagletacs in my kings and Kungs for eons. Well when I tried the ET’s in one light last night it consistantly measured about 600 lumens less than with my Keeppower 3400’s or Panasonic 3400’s. I switched them several times back and forth and they read like that very time. And those Eagletacs are not that old or used. Only about 1.5yr old and perhaps 10 charge cycles. So anyway, with better wiring, I’m thinking these little lights are putting out a little more than the typical 2-2.5a per LED. But I haven’t tested them on tailcap amps since modded. I do need to do that.

The other way around, your SkyRay King has a toroid on the driver, which stopped me from adding a 1/4” disc of aluminum under the threaded shelf the emitters sit on.

The Kung has a nice simple board, very little actually on it. This allowed me to add additional heat sinking as there was more space.

The SkyRay King is very fancy on the outside, with inadequate heat sinking by far…only a thin (approx 1/16”) aluminum disc with like 2 threads on the outer edge so that it screws into place. The Kung has sides to the disc that holds the emitters, giving it more threads and more contact with the head. I also added that 1/4” of aluminum to assist it. In both cases, I was very surprised to see the head a hollow tube, with this thin disc threaded in to make the support shelf for the emitters.

Thanks Tom & RDF. I’m not sure with a C8 I’d want much higher draw anyway. I was mostly interested in the components , so this is great info. That C8 just performs.

RDF, I was thinking one of your posts had a table with some extra info that gave battery and maybe a little more build info; and that it had a few more smaller lights, so just a suggestion. I’m actually glad you started a new thread. (I wish most pics were in the first reply so they don’t d/l after the first page - but that might be weird, too. The warning is good!)

But Dale, this top photo is of the Kung, not the King. The Kings driver is the bottom shot.

I do have some older threads that’s lots of smaller lights. Just look back at some of my older threads. I especially have lots of little lights on my data sheets I de periodically when we do lumen and lux testing. If you can’t find the ones you looking for, just PM me and I’ll see if ai can find what your looking for.
However, brother and I are intending to possible do a small - medium light beamshot page down the road. But not sure if we have enough to justify doing them again. It would be perhaps 25m and 100m shots or something along those lines. We have to research that a bit.

i must have got lucky with a “throwier” Kung too. :slight_smile:
as the kung i have is noticibly floodier, brighter, and throws further with a tigher hot spot than my two Kings and the 6-XM-L King.

As seen here from a recent comparison review i did on them)

Really? I thought the Kung was all black and relatively simple in design, where the King was grey with a red anodized ring around the switch? My memory, can’t be trusted.

The black one with 3 emitters has the non-toroid driver and the additional heat sink. The grey one has 4 emitters and a toroid. Whatever their names are. I seem to have gotten that confused somehow, probably because they’re so close together. But when I sent PM’s telling what had been done the light was in hand, man I gotta tell ya it’s rough getting old! lol

You got the colors and descriptions correct, but the black 3 led one is a SR King purchased from CNQ. Actually unlabeled though. The grey 4 led light is a SR Kung that was purchased from eBay not that long ago.
Just tested amps on both lights using heavy gauge leads, batteries direct on head/driver with no battery tube. The results -
King (black, simple driver, 3 led) - 7.9A
Kung (gray, torroid driver, 4 led) - 6.9A
That testing method is a little difficult to do, so it could be a little off. But I tested both about 3 times using the same batteries (3400 KP’s) and consistently the 3 LED King was about 1a higher.
Of course guys this test was in the modded lights with the xml2’s on copper (Noctigons) and 22g wires everywhere along with good thermal paste. Shouldn’t be too much loss to LEDs themselves.

I agree your shots look like your 4 led light is the throwier and floodier of the bunch. Weird. Of course if I changed drivers between my lights and give the Kung a 1amp boost it would win in lumens for sure. Throw I’m still not sure about.
Weird little lights. But I love them all anyway :slight_smile:

I have a second Skyray Kung order and on the way ( to be a host for a project light) so i will see if that one is different from the Kung i have in the pics above.
I did notice that the emitter wires on the Kung i have somwhat heavier wires than the description you mentioned in your Kung, they appear to be around # 22 or # 20 guage wires in the stock one i have.

thats quite a collection you got there. great choice of lights and thanks for the tedious work that this must have been.
so does the modded king and kungs get hot quicker now too?

Thanks guys for the fantastic shots and effort. Again you have excelled in your little project. You both have a very unique collection.
