First off, glad this place is here, and I'll appreciate any advice.
I'm sort of an electronics dummy, who knows just enough to be dangerous... but anyway here's my issue....
I've got a cabinet lit by 4 8ft LED strings (12V) and max current is about 3.5 amps.
I'm using a 150watt driver like this one https://www.amazon.com/Ledwholesale...sbs_328_2?ie=UTF8&refRID=1K0AFSTCR1VDBEKB7SH5
It works fine at max voltage but at lower light levels there is sometimes quite a noticable strobe effect. I was guessing that since it is dimmed before the driver, the voltage cuts off on the peak voltage levels off the sine wave, the output capacitors on the driver were running out of power before the next cycle. My wild guess solution was to add another capacitor or two between the output and light, so I put in a 10,000 microF 25V capacitor... . Problem is the only effect was to drastically dim the lights and little effect on strobing and adding a second capacitor parallel or series only makes effect more pronounced.
Can somebody try to explain my error or help me learn why this doesn't work?
Any suggestions on how I might fix the issue....short of buying another driver. I have another similar setup on another cabinet with the same problem, so trying to understand what's going on here.
Thanks for you time, Hunter.
