+A few weeks later, I spotted a mistake in my build. I used IRFZ44N transistors but I should have used IRF**L**Z44N transistors instead. The difference is that the Z version needs a higher voltage at the base, so the LEDs were never bright and drew just about two thirds of the power at maximum brightness.
