Regarding the step-down rate. Keep in mind that if you don’t start on turbo, you should have longer before the light steps down from your initial output levels.
The floor is N clicks, to set it to level N, or 0 clicks to leave the current value unchanged.
The ceiling is 151 - N clicks, so 1 click for 150, 11 clicks for 140, 21 clicks for 130, etc… or 0 to leave the current value unchanged.
The ceiling is basically off by one to make it possible to set the ceiling to turbo.
Are there any good beamshot pictures for this yet?
Do I see what the die/phosfor of the ice-blue aux leds produce or is some of it also the main leds excited by the blue aux leds?
There are 150 levels.
When setting the ceiling, 1 click sets it to 150. 2 clicks set it to 149. 3 clicks for 148. And so on.
I’m still not sure I understand the question, but this is how I recommend configuring that:
- Look at a thermometer. Mine says 22 C, so we’ll use this value.
- Go to thermal config mode.
- Calibrate the sensor: At the first “buzz”, click 22 times to tell the light it is now 22 C.
- Wait until the light shuts itself off. If you haven’t changed the value already, this should leave the temperature limit at the default value of 45 C. Otherwise, you could click 15 times at the second “buzz” to set the limit to 45 C. (limit = 30 C plus N clicks)
I received my D4S from Hank today. XPL hi equals on happy fat guy in a wheelchair. Civil twilight at 8:24 pm EST. Toykeeper and all involved THANK YOU VERY MUCH!!! All caps very intentional
So, is the XML HI worth the $18 upgrade and is that how you get the 4K lumen?
I’m not worried about throw. There is nowhere in my yard that is further than roughly 500 feet before the treeline.
If I need more throw than that, I’ll grab the D1S or the BLF GT.
I definitely think so. Again THANKS to all who developed this!!!
Mine just arrived as well.
Happy Strayz….
Nice . I am loving it too… 4 or 5 years ago, this kind of light cost around $230, and output around 3000 lumen…
Mid $60 is hella a deal, and you are getting 5000 lumen…
Going to need more 26650’s this waiting for a cell to charge stinks… I am thinking I need to order 3 more.
Side note, turning the aug leds to high is a lot brighter that I thought that they would be. 
TK said they were usable for a night pee streak, albeit a bit variable in beam.
Guess it won’t bear up to evaluating your kidneys’ processing of local brews.
I find the low aux LED mode works well as a replacement for tritium vials. The high mode is more like a blue moon mode with longer runtime and a weird-looking beam.
Buy it from mtnelectronics if you are in US. They only got 103 in stock… selling quick…
Not all varieties at Mtn are in stock.
I bought 6 of them… those are the best.
Anyone notice d4s turbo mode response faster ? I did… double click to turbo and another double click to return to previous mode function is faster than d4. Lmk what you think…
Seems the same to me but my D4 is the Nichia so it could be emiter or some other variable that Toykeeper will have to let us know.
And Dam this thing is bright! playing with it here in the office and bounced it off the monitor, x-rayed the eyelids. We all do it. Quit laughing, because we know you are going to do it as well, or something else just as reflective. I am surprised that at this point Dale is not working in a room painted flat black, lined in black felt, Or he wears torch goggles.
Compared it with a D4ti with same emitters and after several attempts my D4 was faster than the D4s
Arrived in Aus today, flippin fast shipping all things considered.
brilliant light, like most, a little bigger and heavier than expected, but i like it better this way, build quality very nice.
is a hard reset the only way to turn of momentary?
Edit: “Momentary/tactical mode stays active until battery is disconnected, so it can be used for signalling. No pattern of clicks will exit the mode”.
my stupidity, sorry.
The tail magnet can old a 1 1/2kg weight swinging of it, should suffice.
