There is no factory reset, but it wouldn’t help much anyway because the thermal sensor isn’t calibrated at the factory. That can only be done manually.
To find out what the light thinks the current temperature is, go to tempcheck mode. Three clicks from off, then wait a moment, then click twice. It’ll then blink out what it perceives as the current temperature in C. For example, if it thinks it’s 31 C, it’ll blink 3 times, then pause, then blink 1 time, then pause for a longer time. Then it’ll check temperature again and repeat.
From there, click 4 times to go to thermal config mode. Or, from off, click 10 times. Either way works. The light should then blink once, then stutter or “buzz” for a few seconds. During this buzz, you can click to tell it what the actual temperature is. If you’re in a room at 22 C, click 22 times. There is no need to hurry; it’ll wait until you stop clicking for 3 seconds.
Then it should blink twice, and buzz again. During this buzz, you can set a temperature limit. The default limit is 45 C. To set a new limit, click a bunch of times, one click per degree C, minus 30. So, for 45 C, click 15 times. For 50 C, click 20 times.
The light should then go back to whatever mode it was in before — tempcheck or “off”. When that happens, the new settings should be saved. This should only ever have to be done once.
If you flash Andúril you get a similar UI with 5 clicks for momentary and 4 clicks to lock out.
Andúril is described in the FW3A thread, the first post.
The green D1 I bought a few weeks ago looks like your D4S, looks like it’s faded and washed out. The photos on the website and from other people make it look darker and richer.
many thanks for your very detailed reply, tk, i am familiar with the calibration procedure :)
so i'm gonna go to get a working ambient temperature thermometer soon...
the aux leds of mine are looking really green at low and high with digi cam and eye. it's the nichia version from hank's shop. after the weekend i could post some pictures.
In Neal’s deals for the D4S (seems to be nearly similar price as directly Hank’s but with a few inclusion), it mentions some models have blue/cyan aux leds while others have green aux leds…
I used my copper Sinner with the enlarged copper head and 33mm Quad Noctigon with Samsung LH351D emitters last night and the hot spot is pretty large, out in the open the “throw” is not very impressive at all. I knew that going in of course, so I carried a thrower with me on the walk down to the road. I hadn’t realized just how warm my 5000K 80CRI Samsungs are until last night out in the open, the color or tint is almost warmer than I care for, especially compared to my Nitecore headlamp I was wearing. Still, all in all I like the light for it’s power and clarity….
Had been planning to put the Samsung’s in my D4S when it gets here (tomorrow supposedly) but now I’m not so sure about that…
got carried away
