Amps versus percentage brightness

[Cajun Cheesehead]

Has anyone tried checking this? How does the amperage draw on a channel vary in regards to the percentage brightness?

For instance, if the lights on one channel draw 2 amps when on full power, how many amps does it draw at 75% or 50% brightness

Several people have posted charts over the years here.

The best way to know, is to make your own measurements with your own lights you will be using

I did this a couple of years ago and posted on PC. There are others that did this as well. I cannot find my results but they were pretty much in line with the other tests.

The percentage of power reduction was much much smaller than the percentage of dim applied to the channel. If I recall correctly, you had to apply close to a 50% dim to notice a moderate change in power draw.

Thanks. I found the thread on PC, it is not linear. At 50% intensity, the lights are still drawing over 50% of the full intensity amps.
