I created this account because I need some expertise for my first order at intl-outdoor.
I want to buy an Emisar D4SV2 with Osram W1 on channel 1 and Nichia 519A 5700K domed on the 2nd.
Now I have found a reddit thread that discusses ordering this flashlight with the 2x12A driver of the DM1.12, but I am not sure if there would be any disadvantages in doing so.
My concerns are the following:
1. I looked up some graphs and it seems that Osram W1 does not really profit from more than 4.5A per LED (however this varies between several measurements), while the 519A still gets bit brighter at 6A. If I find out that channel 1 does not profit, can I simply reduce the max PWM value in the firmware and have the same behaviour so to speak as the smaller driver or will this make the lowest modes brighter or "steppier" because 10bit PWM has a fixed resolution?
2. Will I loose other functionality (e.g. no more lighted switch or something else I did not think of)?
3. What could be the general advantages / disadvantages? Are there other things I need to know?
6A is alright for 519A iirc from djozz test, but it’s into “diminishing returns”
But definitely only 9A (4.5A each) for the W1s. If it were me, I’d get the 9A/9A driver.
Would it be possible to ask for a 9A+12A driver? I think it is but I’m not sure.
That way you could run W1s on the 9A channel and 519A’s on the 12A channel.
12A+12A you could use W2’s and 519As. Won’t be as quite as much throw, but much more lumens and a wider spot. W2 can take closer to ~8A, but at ~6A it still performs well.
Personally, I don’t see a point in 12A. It’ll regulate itself after couple of seconds to much lower value because of heat. I’m wondering if difference between 9 and 12 is perceptible by human eye. With lower starting current there is a chance that it’ll be sustained for a bit longer.
Hank only sells it bundled with the USBASP for 15$, and I already have several of those programmers… If he had the pogo adapter individually for a reasonable price I would buy it from him.
