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
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.
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.
I’ve been really disappointed with the new Emisar finish so far, aside from feeling cheap and unpleasant to me, it flakes off too easily. I have a D1 with the original finish and it is flawless despite much harder use.
Thanks for the beamshot comparison, looks pretty promising.
goshdogit, that’s a really good beamshot / hotspot comparison. The PCB pic also reminds me I still haven’t taken mine apart to get pics and reflash it…
I didn’t get a shipping notice or tracking number, just an order confirmation email. I didn’t notice that at the end of the message, it instructed to reply back with my phone number.
Neal sent me another email a few days later asking again for my phone number, but I didn’t see it for several days because it went to my spam folder.
The D1S got here only 7 days after I replied to the second message with my phone number, so I wonder if Neal sent the light before I replied. Oddly, there are no dates on either of the shipping labels.
When I placed my order it gave a date of when it would arrive. I let it go 4 days past (I live in Alaska and somehow it takes a week longer to get priority air mail….) before contacting Neil.
He pulled a tracking number for me and it was here shortly after that.
I did not have any dates on my package either.
give him an email and see what he says and see if he will send a tracking number. I know all orders going forward for me I will pay to have tracking number so I can watch it fly around.
