That is correct from a power level perspective, but 2A for instance would make for an perceived LED brightness level of approx. 67. From the previous post a 50% perceived brightness level of 4A max, would be a power level of 4A x 75 / 255 = 1.8A. Similarly, 25% LED brightness would be more like 376ma.
To put it a different way, power level and brightness level are two different factors to consider.
Sorry guys,
Since I’m new to building lights I wasn’t getting what I was after worded properly.
I’m not after actual brightness, I’m looking at power levels/heat/ run times.
Not a problem, just pointing out the fact that the difference between 2A and 1A is very small in terms of brightness. For me personally the spread between the two brightness levels is inconsequential. So why not afford even more power savings or run time, if that is the criteria, with a lower PWM mode?
