On the 150 scale, how many clicks down to make the ceiling equal to the max regulated?
Trying to stay out of hybrid/fet to max runtime.
unscrew the tail for a sec and one click gives you max regulated.
Agreed.
Do you know how to program that as the max ceiling?
According to the D4S config file, it would be 68 or 69 but maybe TK will confirm.
Looks like 68. How long you want it to run?
I’m setting the stepped ramp where I know I will have over 5 hours of good light.
I’m keeping the smooth ramp side a little higher for more light.
Good idea. I use similar set up on my d4.
Maukka, do you know if that is 68 down from 150 or 68 up from floor?
To set the ceiling level to CEIL, the number of clicks is 151 - CEIL.
So…
- For level 150/150, it’s 1 click.
- For level 120/150, it’s 31 clicks.
- For level 83/150, it’s 68 clicks.
The D4S highest regulated level is 83/150.
awesome! Thank you TK!
Wonderful programming by the way!
You can get a little more sophisticated if you want by playing around with math (or the steps.py script Toykeeper made). I figured this out when setting up my ROT66 to have steps that fall on channel boundaries. I’ve got 10 steps. Step 1 is level 3 (I had to compromise slightly on moonlight), step 6 is max 1x7135 and step 10 is max 7x7135.
I did the math in Excel, and double checked it against the steps.py script, which uses the same math as the Anduril code.
If you want a specific middle level, like a channel boundary, you have to compromise your floor or ceiling levels, your number of steps, or both.
I went ahead and calculated a couple that should result in a level 83 for the D4s, while also providing level 1 (minimum moonlight) below. The default ramp ceiling is level 120.
In use, it would be up to you to remember which stepped ramp level is your max regulated level.
Floor, Ceiling, # of steps (resulting levels)
—
1, 125, 4 (1, 42, 83, 125)
1, 111, 5 (1, 28, 56, 83, 111)
1, 139, 6 (1, 28, 56, 83, 111, 139)
1, 125, 7 (1, 21, 42, 63, 83, 104, 125)
Also, I don’t think this quite works for the Nichia version of the D4S. The compression of the ramp to 80% of max FET looks to me like it is done by slightly overlapping the regulated and FET ramps, if I’m understanding the config files right.
Lucky, 1/120/4 is how I had it set recently. I really liked it.
I just programmed 1/83/4. Gonna see how it works. I use the lower modes 99% of the time and access turbo only for show off.
I will end up playing with all of your numbers tonight just for fun!
The only difference between the regular and 219 versions is that the 219 version has its FET ramp numbers multiplied by 0.8. However, as a side effect, it means that both levels 83 and 84 are the maximum regulated level. I hadn’t even noticed until just now.
I got what I needed from this thread. Thank you everyone.
OT - I now have the smooth/step programmed completely different so it’s like having two different lights. Wonderfully planned programming.
Any other weird tricks hidden in this light?
Oops. I must have mistakenly copy and pasted only part of the PWM2 array from “cfg-emisar-d4s-219c.h” the first time.
I just checked again and do indeed see the FET first turning on at level 85 for the 219C.
