ummmm.....  anyone think that the unit is sending out a ripple?    8 volts DC at a frequency  that it is reading on an AC scale on a DVM ?

I get funky readings on AC when trying to read a DC circuit.

since it is designed for lighting LED's the power supply is crude and does not have to be ripple free.   you can easily run your LED's at a pwm with 50 volts or so.  the LED is more concerned with wattage so your slices have to be pretty thin so any ripple my not be worth worrying about.

this is not something you would want to use on any logic circuits.  and definitely not on your duino.

Ok people
I appreciate all your views and it is clear that the led driver is only useful for that stated purpose. Would something like this do the job?:
