Anyone knows when D1S hits the market?

I’m not sure, but it should be very soon. I think Neal already got some, so RMM should have them soon too, and Hank will probably put up the product page soon too. It sounds like it could be as early as this week, but I’m just guessing.

Dubble click for turbo and ramp down if needed.

It’s funny you mention that, since Anduril has a mapping specifically for that purpose. From off, do a double click but hold the second click, and it’ll start at the ceiling then ramp down until you let go.

This works in both smooth ramping and discrete level UIs. They’re the same UI, really, except that one has a stair-step shaped ramp and the other is smooth… so there is no need to remember different actions for each.

I don’t think the D1S will ship with Anduril though. Maybe in the future sometime, but for now it’s still a work in progress.

D1S with the shorty tube might be one of the funniest things I’ve seen in a while.

Me too, but it’s surprisingly well-balanced like that. At least, if you hold it by the button section, which tends to happen naturally, the balance is pretty decent. The back section is small, and the front section is mostly air.

With an 18650 cell, it’s actually a little back-heavy. This is fine though, since with thumb and index finger on the button section, the battery tube rests comfortably on the other three fingers.

Tom, a member of the German flashlight forum (Taschenlampen Forum) is in contact with Hank and will get a D1s for review

He was told that the D1s will be the same price as the D1

Toykeeper, great review!. I’m loving my D1 so much that I’ll be buying the D1S as soon as it comes out. The best UI and excellent build quality says it all for me.

It’s good to know that the D1S does not have the quick stepdown of its brothers. I don’t see why I should buy the D1 instead of or in addition to the D1s other than the former being more compact or pocketable. TK have you done a full runtime test for the D1S at Turbo?

I’m pretty surprised to see you compare the D1s to the SR-90 Intimidator, as the Intimidator had a vastly different setup from the factory. If you configure the Intimidator in like kind, there simply is no comparison. With a de-domed XM-L2 and similar amperage as the FET driver, the big SR-90 made 665Kcd for right at a mile in throw.

I really do like the style of this light though and would like to get one as soon as possible, whenever that may be. Wink

I compared it to the SR90 because selfbuilt measured it at 112.5 kcd of throw, and my D1S gets 123 kcd.

Physically, they’re almost nothing alike. The SR90 is huge, and can throw a lot farther when given a different driver and LED. But in stock form, their throw is pretty similar.

When the SR90 was new, I saw his review and wanted one, but couldn’t justify the price or the size. It kind of stuck in my mind though, as a milestone to aim for someday… and now that milestone fits easily into my purse.

Nope. Mine has non-stock firmware so it wouldn’t be a very useful test result anyway.

However, the graph should look pretty predictable since it doesn’t really need to step down. Typical direct-drive curve starting at around 6 amps and going until LVP kicks in. It’d probably run about 45 minutes before LVP.

In that case, don’t get one. Smile These things come in multiple flavors because different people have different tastes.

I like the D1 (18350) because it’s small enough to EDC, and throwier than any of my other EDC-able lights. The D1S throws a lot better, but I find it’s too big to conveniently carry around.

But of course, and the SR-90 was equipped with an Luminus SST-90, an emitter not like anything else on the market in construction and output as well as current capability, and cost right at $400. Vastly different light, in size, output, beam profile and virtually everything else about it. I have the SR-90, got it with a Vinh modified SBT-70 and was asked to change it for better throw. This done, the owner soon got out of flashlights almost entirely and gave me the light. Comparing a vintage model to a sleek new factory racer is not really fair. Wink

Since the D1S is virtually a modified flashlight, straight from the factory, it really doesn’t compare to other lights it’s size until said lights are modded in like kind. This is one of the great things about it, Hank took care of the details so we wouldn’t have to! Smile

I like how it’s a D1 with an enlarged head from the D1’s bezel up, keeping the family resemblance in form as well as UI. Very nice! (tempting to simply recreate my D1 into such a monster as this my own self. Wink )

It would still be useful, because some of us here aren’t planning on staying with the stock firmware Big Smile . Thanks for the estimate anyway.

I agree, to each his/her own. I just wish the D1 could maintain its output at Turbo a little bit longer. But I know that would be difficult without getting into problem with its temperature.

As a side note, in the Thermal Regulation section of your review, I noticed you labelled the y-axis “Relative Brightness” but the figures are in lumens I presume.

The cyan color is exclusive for the D4.

Nope, but it can be nice on occasion to see how far we’ve come. For example, a $5 Raspberry Pi Zero performs better in almost every way than a computer I got a couple decades ago for $5000.

Five years of development has done good things to the size and price of high-performance flashlights.

You can set its temperature limit higher. I showed one with default settings, which are pretty conservative, and it still went over a minute before any adjustment happened… or about 7 minutes to settle at a stable temperature.

Ish. I used zak.wilson’s ceilingbounce app to measure that, and it relies on my phone’s light sensor… which doesn’t seem to have a linear response. So the values are not in lumens. I scaled the peak of the graphs to match the peak lumen values I had measured earlier with better equipment, but everything below that is skewed.

Now you got me wondering how the SR-90 would perform with an XHP-35….

Also wondering where to get a Utorch UT-02 driver… how would the D1S do with an XHP-35 HI? Big Smile

Also wondering how close I can slice an XP-L2… would it be like an XP-L2 HI? Today may be a good day to hone the scalpel. Wink

Just sliced an XP-L W2 2B on a 20mm Noctigon, charging up the Sanyo 20700A to see what she does in the D1. Smile

Wonder if this H2-C boost driver would fit

edit: seems too tall after re-reading TK’s measurements

I’m getting 1397.25 lumens on the sliced XP-L W2 2B, should be higher than that seems like. Color is good on it, wish I could find more of these emitters. They are NOT the XP-L2, the W2 shows bond wires and the little dots on the phosphor, while the XP-L2 is like the XP-G3, like upside down with no bond wires or dots and the egg yolk appearance. This W2 shows the smaller flat on the side of the dome, so I know it’s different but can’t find a source for them. The second time I ordered from Cutter they sent something else. Go figure.

contactor, if it only gave 1.5A to the XHP-35 we’d be better off staying with the XP-L HI, or a de-domed XP-L or XM-L2. Perhaps a de-domed XP-G2? Maybe a buck driver to run two of the Aspire 18350’s and push the XP-G2 de-domed to around 5.5A?

Or figure out what works to de-dome the Luminus SST-40 and push it around 7A?
