Now you got me wondering how the SR-90 would perform with an XHP-35….
I guess you’ll have to tell us :innocent:
Also wondering where to get a Utorch UT-02 driver… how would the D1S do with an XHP-35 HI? 
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. 
Just sliced an XP-L W2 2B on a 20mm Noctigon, charging up the Sanyo 20700A to see what she does in the D1. 
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?
What is the lanyard ring that’s used on the D4 in this pic from the review?
That’s a Solarforce pocket clip, the clip is on the other side.
Fine tuned the battery crusher, 1438.65 lumens on the XP-L W2 2B sliced.
The H2-C boost driver is probably way too thick. The driver cavity on a D4 is pretty shallow, with virtually no extra room beyond the clearance needed by the attiny85.
About the lanyard ring, it’s part of a SolarForce L2 clip. It’s the best clip solution I’ve found so far, but it doesn’t work without modifications. The inner diameter needs to be expanded, and the tailcap needs a washer to fill the gap created by the clip ring.
These technically can work on the D1 or D1S, but it’s awkward due to the head being wider. The D1S in particular has a pretty small gap for fabric to fit into. But it works reasonably well on a D4:
Thanks for the reply. What I’ll do is use a Solarforce L2 lanyard ring (no clip).
Is it just me or is that grey D1S calling out “Daaaaaaaale! Daaaaaaaaaaaaale!”
D1vn with sst40, really impressed with this light and dare i say, actually prefer it to the xpl HI 5000k. My preference will usually always be 5000k over say 6000-6500k. Certainly for flood bias lights. However in thrower bias, its not a must for me. The beam is pretty much white, have to really inpsect for any rings. In use, its a very nice beam, huge hot spot(at a guess its about 2/3rds larger over the xpl HI. Spill is brighter, in fact its that bright it makes it even more useful for me.
The sst40 is great in the D1, would also be nice for some additional 4000k and 5000k flavours :+1:
I can hear it from over this side of the pond!!! quick quieten the voices(i have enough of those myself)
Lol, I put Intl-Outdoor in my main header for bookmarks so I can check it regular. Addict, yes I am!
My Solarforce Skyline I has a crazy deep reflector, I’m actually considering pulling the reflector and building a head for the D1 to hold it. I gotta have it really bad, need help. . . .
Seriously, it’s crazy! 38.3 opening at the top, 56.1mm deep!
Your normal, you are always aspiring to improve and better……………….nothing wrong with that and having the skills to do it. Imagine a few years back, someone suggesting a bit of plastic, some type of screen and talking /sharing pics around the world with other people via something called the web!……………that is crazy! Crazy today, the norm tomorrow
How does the heat compare to stock? Should be more efficient here.
When will the D1S be available to order? Any special discount code in the works? Interested!
