OP wins. Personally, I hate the bright yellow stain in the middle.

Guys, I would really appreciate your beamshots of the D1 with the FC-40.

5462

I just got my D1 with the 4000k-4500k FC-40 in it. The tint is below the BBL which is nice.
The sustained lumens seem to be around 330 lumens. I get about 1750 at startup but after about 10 minutes, I get 330 lumens.

This seems really low for this boost driver. The D1 I have with the B35AM can sustain over 700 lumens no problem. Anyone else have any performance measurements?

5463

When I tested KR1 with FC40 I found sustained output to be around 500 lumens (after calibration and with the stock thermal ceiling of 45C), so 350 does seem a bit low. Do both of your lights have identical thermal settings (both calibrated and with the same thermal ceiling)?

5464

I just found your review before you posted, they are both at the same thermal calibration from factory. The FC40 settled around 56C. Both verified with an IR thermometer, the cell voltage may have been a bit low on the FC40 but being a boost driver and all I wouldnā€™t think it would have much to do with it.

I was surprised because I thought it would be more like 1000 sustained lumens, until I read your review. Now I am not too concerned, I guess I just thought it would be more efficient than the Nichia. Nothing to be concerned about now that I know. Iā€™ll double check all measurements tomorrow.

Perhabs you can try the 700lm by start with 700lm directly, because if you start on turbo the big LED make a lot of heat for this small flashlight ā€¦ and it need sorry a long time to cool down and increase the output again ā€¦

5466

I always set 60deg thermal ceiling so i get plenty of output steady.

Since iā€™m using all my flashlights at work having it that warm doesnā€™t concern me much unlike other folks that are using them casually.

5467

Make sure to do thermal calibration on all your Anduril lights when you receive them. Factory calibration is often wildly off and can cause huge variations in performance. If your light is SETTLING at 56C with a stock thermal ceiling of 45C then itā€™s not calibrated.

That might explain why B35AM performed so much better for you, since itā€™s possible that light thinks its running a lot cooler than it actually is. I measured about 350 lumens sustained output from a B35AM in a DM11 after calibration and with the stock 45C thermal limit, fwiw.

5468

I always set them to 55C when I get them.

5469

Did you calibrate them? Thatā€™s a different setting than adjusting the thermal ceiling.

5470

Yup, learned my lessons long ago. :smiley: I will say these new boost drivers came very well calibrated from the factory.

I ran my tests again, and I am getting 500 lumens sustained. The calibration and thermal ceiling both at 55C. The cell when I took it out last night was 3.1v, so maybe it took a step down and I hadnā€™t rechecked its temperature. It was a very abused Sanyo NCR18650GA.

OKflashlightaholic from reddit made a working 26800 tube for his K1 :sunglasses:

5472

see this Hank can simply make this 26800 to be frankensteined for all his light but he keeps the last thread just to leave us some fun with modification

5473

So Hank, when you were plan to tell us that D4K in stone white about to be released?

D4V2 21700ā€¦

My wallet is not ready for that D4K but I am!

5477

21700 D1V2 next?

5478

I hope so!

5479

Please use the larger switch on 21700 models.

Will there be more green DM11ā€™s available, or is it only grey and black from now on? I see itā€™s not an option on the web site.
