I also registered yesterday, and awaiting a reply. I’ll allow a few days, as I’m sure M4DM4X has a life away from flashlights as well!

Not sure if I just got lucky but I got a reply within minutes after I sign up this afternoon.


Was that just acknowledgement or did it include the password?

Yes, password too. Maybe I got lucky.

It came so quickly I figured it was computer generated and not done by him personally.


Interesting, still waiting for my password….

Thanks Neal Just bought the D1S to add to my D4 and D1!!!! It was nice getting a 18350 battery shipped also.

The wait is no problem.Just being able to get shipping included to Canada is FANTASTIC!!!

Edit: Will LG MJ1 be suitable for D1s or should I order a new battery too?

Gahhhhh…. I’m a dork.

Don’t be like me, Check your spam/junk folders if still waiting for registration approval.

Back on topic – just when I thought I had reached ‘peak flashlight’, here comes another! D1S ordered.

I would assume that button top VTC6 or 30Q (66.5mm length) should fit OK?

I think that should work. It looks like anything up to 67mm is probably okay.

Not sure that I can call the D1S “peak flashlight”, but it is unusually throwy for its size. You could also make it throw even more by putting in an Oslon Black Flat or dedomed XP-G2, if you don’t mind a smaller hotspot. Getting it focused properly may be a bit tricky too, because these things usually are.

When I take one with me, it’s usually the D4 or D1, or both, because their smaller size makes them more convenient. The D1S can fit in my purse too, though it’s a bit large to have in there all the time. But when I’m not concerned about convenience at all, I’ll probably use a BLF GT. That’s a lot closer to what I’d consider “peak flashlight”, considering that the whole point of it is to “turn it up to eleven”. ;P

When I said “peak flashlight” I was referring to having far too many flashlights and not needing any more. Smile

I put a sliced SST-40 in my D1 and got 2160 lumens, 39.25Kcd. Haven’t checked amperage draw but it’s probably up around 8A.

I’ve already got 150 lights and still have 3 on the way. Wink Usually more than just one that’s waiting to be bought… Big Smile

Got to thinking about the beam profile and output of the SST-40 in the D1, I changed out the emitters in my Q8 this afternoon as one of the XP-L2’s was damaged, so I used one of the 3 remaining XP-L2 V6 1C emitters in the D1 and it’s making 2387.4 lumens from a freshly charged Sanyo 20700A. Serious little monster it is! Big Smile

I thought about slicing the sst40 in my d1 but it gets 2400 lumens and 44kcd think i’ll just leave it alone.

What’s the maximum current draw of any configuration of this or the D1 or D1s? I’m guessing a 4 LED will draw more current than the XPL? So far I’ve seen that the D1S tops out at 6A with the XPL I haven’t seen anything on the 4 up configuration.

Actually, given DBCustoms’ comment about 12 Amps or more possible, What I really want to know is what’s the best 18650 to use in these beasts. The 3 best ones in HKJ’s review do fine at 10A but don’t like 15 A at all.

Thanks.

Quad’s can run up to 12A or more, where a single emitter isn’t usually so high. The new emitters are breaking new ground though, with the SST-40 capable of well over 9A and the XP-L2 also up there towards 10, surprising really.

The highest current draw I’ve seen to date in a flashlight is a triple XHP-70.2 I built, pulling 32.2A from 2 iJoy 21700’s.

Thanks! I edited the OP before I saw your reply. What do you think the best 18650 battery for these D series is given that the top 3 in HKJ’s review could handle 10 A but wouldn’t survive 15?

Thanks.

What is the actual size (Diameter and depth) of the aluminum reflector inside the D1 and the D1S?

Thanks!

Hi Dale, Where did you get your SST-40, How close to the die did you cut and how much did the tint shift? Thanks!

There are quite different current draws between the D4 (reports of up to 20A) and D1/D1S (6A). I would assume that the usual suspects 30Q/VTC6/VTC5A would be cream of the crop in the D4. Given the lower current requirements in the D1/D1S I would expect that performance with Sanyo GAs wouldn’t be too far behind the higher drain batteries. However this is purely theoretical – I’m sure others can chime in!

Stephen nailed it, survival seems such a harsh word, if a cell can’t deliver 15 to 20 Amps in a quad then it will give what it can, it’s not gonna die just because the 4 dies want more. A Panasonic PF may give 8 or 9A where the 30Q gives 18A, both survive, the light just makes less output on the lesser cell.

VTC5A is probably the top dog, with VTC6 and 30Q hot on it’s heels. Efest 3000mAh in the dark metallic purple is right up there with them. The LG HE-4 also is an excellent performer. The LG HE-2 isn’t far behind nor is the 25R. The Efest 35A is still an excellent and viable choice. There’s a lot of cells that will work well in the D4, all of these will get the light too hot to hold in short order.

I did this cell test in an HD2010 variant light equipped with the Luminus SBT-70 emitter. Notice how some cells can produce very similar output in lumens at quite different current draw, yet all cells tested worked in the light, albeit with varying results. So a lesser cell can be used to control max output and thus, heat. If you’re loaning a hot rod light, equip it with a lesser cell to ensure the noob doesn’t damage anything. The lesser cell doesn’t die, it just doesn’t deliver the max power. The only case where survival may come into play is with a protected cell, it’s possible these turn off and won’t come back on if a high discharge activates the protection circuit. Good protected cells won’t do this, but there are a lot of different protection circuits on the market..

I would be interested to see any comparisons in output between VTC6/5A/30Q and GAs in the D1S when people start to receive them. (I need to order a batch of 18650s and would prefer the latter for use across my different lights if they perform well).

I must have misunderstood HKJ’s graphs. I thought that the exponential temperature rise of over 50C (nothing over that temperature shows but it’s clear the temperature rose more than that) meant the battery was going to overheat if that amp draw continued. Very few batteries stayed under 50C at 15A draw and none did at 20A. The Sony VCT6 did the best

http://lygte-info.dk/review/batteries2012/Sony%20US18650VTC6%203000mAh%2...

Here are the 3 that did the best at 10A draw, with the Enercig beating out the others in mAH in testing down to 3.0 V.

Sanyo ncr 18650 GA

Samsung inr 18650 35E

Enercig 18650 3450

http://lygte-info.dk/review/batteries2012/Common18650Summary%20UK.html

Reviewing those graphs and doing some background checking it looks like the enercig is the VTC5A and it wins the 20A discharge wars. Thanks for the help!

I have the D1 xpl hi V3 1A set at 70 degrees c and showing 29 degree pcb indicated temp for both tests.[ambient 22 c]

I tested the VTC6 versus the GA

The VTC6 at start 1182

at 30 secs 1108

at 1 minute 1075 lumens

The ncr 18650 GA at start 1107

at 30 secs 1074

at 1 minute 1021 lumens.

As you can see there is a little difference in output. I personally like the sony the best as it can run most of my lights and the difference in capacity is very little between the two.

Differences of 100 lumens at this values are not perceptible.

Thanks for the info. So the GAs are only -3.1% to -6.3% less.

Almost any decent cell should be fine in the D1 and D1S. Output on turbo may differ by small amounts, but usually not enough to be perceptible. They shouldn’t have any significant issues putting out that much current.

The D4 is another story. It tries to draw enough power to damage lesser cells. Usually the thermal regulation will reduce the output before anything bad can happen, but you could still run into issues with a first-batch model before regulation was added, or in really weird situations like if you held the button in momentary mode at turbo while wearing a heatproof glove.

In either case, good cells are certainly recommended, but it’s not as important with the D1 and D1S.
