I need some help/advice on how I can dim my led lights.
I've bought an ATS from Aliexpress. From my experience using my current DIY ATS, I'm pretty sure I need far less light intensity and I would really like a dimmer for the led.
Before buying, I just assumed it would be some 12 or 24v LED lights and thought I'd use a cheap simple dimmer switch (the rotating kind) like the one I'm using for my current ATS but I don't think the lights are 12 or 24v.
I don't know much about electronics (so I could be wrong, in which case, please correct me) but judging by the power adapter (24-46v, 300mA), the number of leds (12), and the power of lights (12w), I'm guessing the leds on the pcb are in series and around 3v, 300mA each? I haven't taken the light-box apart because it's sealed. I don't even know what the 24-46v on the adapter means. Does it mean the voltage is somewhere between 24 and 46?
I don't think the 12-24v dimmer switch would work in this case. From what I understand, led dimmers work by adjusting DC current (ampere) or by turning on and off very fast (PWM dimmers). Would a PWM controller (like this) work for this light? Is there any other way to control this light? I've heard not all leds are dimmable and what works for one may not work for another but if it's not too costly or risky, I'm willing to try something out.
