It has begun- 5 XML torch

5 xm-l's in a 2x18650 setup. WHOOOOO. RUNTIME BEAST!

even with 3x18650 it'll be something to pity if they are driven half decent. Although I guarantee if they are, you couldn't run this thing on high for long.

Bingo,

They are not able to make a decent triple XML, I can't imagine how this 5*XML wil perform

Until the opposite is proven... no more SkyRay for me neither.

Though,I must say, it has a nice big head!

It seems like with 5 x XM-L you start getting into HID Xenon territory, meaning the efficiency of LED's at that level starts to drop off and you could just as well go with the HID light. That's if we're talking 18650 cells. Operating on 25500x2 or 32600x2 is a whole different story. That scares me a little bit, though. haha

After looking at that setup I had a thought. Order a spare 2 18650 battery tube if possible then direct drive with 4x 18650. Talk about a torch!! Obviously runtime heat would be an issue but still......

Thanks for taking one for the team! We will be looking forward to your review.

But am not going to buy one.

At least not till someone else gets one and tells me they are wonderful.

And I've got some spare cash.......

:(

I´m just thinking out loud here, but to me the wires running to the headunit looks thin?

I mean 5 x XML running at what? 2,5A to 2,8A? Multiply by 5 and and you are getting close to something you can weld with

And isn´t there some rather interesting issues with running 3 x 18650 batteries in series or is it my memory playing tricks...

Says driven at 1.5A on Manafont. If that's the case, that's lame. I'll pass.

Wiring, driver, amperage to the LED's, quality control, reliability... its all speculation for now. Lets wait till spambot receives his. Then we will have a better idea if this is something we should all campaign for on a group buy. This might even look good with a BLF logo on the side!

Id like to see 3A on high and somewhere around 1A on medium (I know... wishful thinking). Its good to see the driver separated from the head with a fair amount of surface area and fins for heat sinking. It could always use more but the leds being isolated should make it far more reliable, even if it does tend to run very hot. Lets hope for a great driver this time.

I noticed that too. This will probably put out less lumens than the DRY 3x XML.

I'd pay for that kind of $$ if it's nice with HA/NW LEDs, either that or it has a bigger head. But i guess it's the usual 1A tint 7000k kind of stuff, and the head's not bigger (100mm would be bice). I think i'll wait for the DRY penta XM-L with 5 x 18650. LOL!

There is no way to DD this if the driver goes poof. 5 x XM-Ls....need 2 more extensions. Pretty hardcore.

SR3800 is 160 lux ceiling bounce. Divide that by 3 and then times 5, that's 266. That's just DRY + UCL territory. Throw won't be different, same sized reflectors (just more of them). It says 1.5A, well don't take it at absolute value but with the prev SR3800 specs to be at 2.5A that means...well i don't know.

If today's the same as 2009 in April, I think anyone's in the market will buy every light in CNQG/MF/DD/lightmall/DX. LOL! But no....

It's the bigger version of the SR3800 rev 0, current DRY triple XM-L, ala not too bad. More fins at the head-tube part but if there is no cold wind then that does nothing at this kind of level. It runs on 3 x 18650.

Someone mentioned the thin wires, that's prob ok since it's prob doing like 17V and below 2A and anyway it's a v short length.

Now if they manage to put in a single XM-L and 73mm reflector, then this would certainly hang around 80k....that'd be something. The DIY crowd did that before with the 73mm DX reflector (the TF X6 reflector)

The redeeming thing is - this might run at DRY output levels but run very much cooler hence capable of running much longer.

Don't look at the OTL (it's OTF) warm, but the cold OTL. In reality just minus about 10% and it's really close. In the DRY, I ran a 3 min run in turbo 4 amps and it dropped only 7% at 17 deg C temperature...it's not a 30 seconds flashlight.

asd

Too long, I think it MUST be fatty, like the dry but with 6x batteries (3+3), or maybe 5+5 because of the big head. That would be nice.

3-26650's would be nice instead of 18650's.

If say 1-2 months from now, we really see a properly driven 3A per emitter/DD penta XM-L, this would easily be brighter than the best 9 x XP-G with updated 1550mA board Mac customs Maglite and throw quite a fair bit better.

Going just by power consumption at the LEDs:

A DD triple XM-L: approximately 4 A x 3.6 Vf x 3 LEDs = 43 W

FuturePentaLight: approximately 3 A x 3.6 Vf x 5 LEDs = 54 W
or if it is DD or close to it: 4 A x 3.6 Vf x 5 LEDs = 72 W

Wow man... 70+ W, plus losses. Who's gonna be the first mfr to put a fan in a light? If fans are not feasible, then we might have hit the wall for now. We might need to wait for Cree/Luminus/Philips to come up with something amazing.

Peteybaby, the diff between 3 emitters and 5 emitters is that the 5 emitter would be much more efficient when driven below max. But if talking about DD or near DD levels for 3 and 5 x XM-L then yes it's gonna be hot and the 5 emitter would produce 60% more heat than the DRY (easier to talk in terms of percentages). But anyway this is a bigger host + head = more mass and surface area (not sure if that amounts to 60%). It's 590g for the packaging so it's pretty massive.

Yes I just wrote that a few days ago in another thread. :)

I like thinking in terms of wattage because I worked for years in power electronics and I have a good feel for it. And other people can compare to incandescent light bulbs. :)

Let's hope that DRY comes also with a 5*XML with extended fatty body for 6x18650 battery set up, wishfull thinking

Dry 3-mode CW + UCL is my all time favorite at this moment, even brighter then Nitecore TM11.

Wish I could pump up the TM11 at the DRY skills, TM11 has the ultime body for me with the almost perfect U.I.

O yes, yesterday evening with a temperature of +- 4° C, I was able to use the turbo for more then 45 min without running too hot with ExCell 3100

So with those low temperatures you are able to suck those 18650/3100mAh DRY in turbo mode without gearing back

I would like one like this in a 2+2 batteries allocated parallel, I mean like Fenix TK35 form factor but twice as long.

Being driven at 1.5A per led, would make it a really high efficiency flashlight in my opinion.

Looking at this table Math made ( https://budgetlightforum.com/t/-/2346), take the 1.4A instead as there is no measurement for 1.4A, 5*520.9= 2604.5 Lumens, with a total power consumption of 7A.

A three XM-L driven at 3A, will give us 3*881.4= 2644 Lumens, with a total power consumption of 9A for roughly the same lumens, so I do not think it is a bad idea, I know we as flashabolics always want the maximun we can get per led, but 2600 Lumens is not a bad thing with such performance.

And one more thing, 5 XM-L at 1.5A will generate probably less heat than 3 at 3A, which will be translated in some more Lumens.
