It has begun- 5 XML torch

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.

I'm not sure about the heat, but the rest is well said Yavi.

Yavi is correct about the heat too: "5 XM-L at 1.5A will generate probably less heat than 3 at 3A"

5x1.5 = 7.5. 3x3 = 9. So even if Vf is the same for both cases, the 5x XM-L 1.5 A model would dissipate roughly 7.5/9 = 83% of the heat that the 3x XM-L 3 A model would. And it's even better when you consider that the Vf will be lower with the 1.5 A model.

This is exactly what I had in mind when I planned my 5x XM-L drop-in, early this year before all the complete 3x XM-L lights came out. People said my light would burn up, but I wasn't intending to run the 5 LEDs at 3 A. I just wanted the max output I could get without burning down the house, and I'd get more efficiency with 5 LEDs.

I have posted a diagram above but mine's 3.8A. But it's around there, check out the efficacy.

It would have been more tempting if they used U2/3 bin. And more expensive too I suppose.

I'm more worried about the wire twisting when you re-install the head to the body. And on top of that, thermal issues, the heat has to travel from the head to the heatsink, through 2 layers of anodising, through threads. Not a lot of heatsink either.

Why penta XM-L, your going to get one serious flood master. The dry seems to be a more desirable setup?

Ditto. I've noticed that occasionally, they don't put a lumen rating on a given product. I wonder if it has to do with a customer complaining about the accuracy of such claims.

well at lest they planned ahead and are selling spare drivers this time lols

Circuit Board for Penta-LEDs 5 Modes Module

ill stick to my TR-3T6 looong run times dont have to wait for Australia to freeze over to use it on full bore, i would consider a TR-5T6 way before the fry rays, but 3 x T6 has more flood then you will ever need.

In the past I would have been tempted to buy this...BUT after recieving a DOA Sky Ray from Manafont and all the bulls!t they put me through before they would let me send it back; Only to loose all my money on the purchase & return shipping cost. I'll be dam if I would trust sending Manafont $106.50 if it arrives DOA, your going to be out your cash; good luck!

I'd wait for DX to carry it, IF they ever do; and if they don't no worries, no loss.
