We have a lot of ambient lighting in and around our house. Often, the lights we choose come with controllers to dim the lights. But I often have to modify them for our needs. And that's where these PWM controllers will come in handy. They appear to be well built and they do work very well. This summer we are planning to make some changes to the lighting. I'm looking forward to using these to help balance the brightness of the lights.

4PCS LED Light Strip Dimmer, DC12-24V Frequency Adjustable,30A PWM Dimming Controller for Dimmer Knob Adjust Brightness Single Color Light Ribbon Channel for 5050 3528 ON/Off SwitchThe dimmers are lightweight but seem to be well built. The enclosures are metal for added protection. The circuit is a basic PWM circuit controlled by a potentiometer and it works well to modulate whatever DC voltage you apply.

The switch seemed to work perfect when I first installed it. But now a month later the lights are flickering and sometimes it doesn’t even work. Great if you’re looking for a strobe light not for a light switch. I got this to replace the aloveco brand dimmer that I replaced with this after it failed after 3 years of use. I was hoping to get at least that much use or longer with this brand, but it is nearly useless after 2 months. Now I’m looking for another brand that will have more longevity and functionality.

Dimmer is well constructed and covers both common voltages. Dimming is smooth and even across potentiometer sweep.

Very nice dimmers for low voltage lines (12V-24V) that can handle up to 30 amps each. The aluminum enclosures are rugged and mountable (you'll need to provide your own screws), and there is a hinged plastic cover over the input and output connections.
