Wawa:
That strip seems to be a mix of common CL resistors and a tiny linear regulator (I don't see any inductors).
I would still call this a constant voltage strip (with a little bit of regulation).I don't see any voltage window limits in the specs where the regulation would still work or fry the linear chip.
This strip should be PWM-ed low-side with a locic level mosfet.There are many low voltage CC LED drivers available for the Arduino,
but they need to be matched to the LED you're driving.
Give us a link to the 'other' LEDs you want to control.
Leo..
The problem is that in this case the voltage (or if we go CV then the current) would be quite high because we need to dim a lot of lumens at once.
For example, if we used 12V CV strips like this then we would have to go up to 8A to get the amount of light we need. What kind of logic level MOSFET can deal with that?
