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.
I’ll include my D1S tracking info so you don’t feel left out. “Send to Chicago 11/08”

Since it requires soldering for each reflash, I’ve been kinda waiting until I go back to tweak thermal regulation again… and I’ve dragged my feet on that because it’s a long and obnoxious process.
My last D4 thermal regulation test showed some pretty annoying oscillation, but perhaps it’d be fine on something with a lower power-to-mass ratio. Perhaps I should flash the D1 as-is and find out.
