Review on 🎛️ Oznium Mini LED Dimmer Knob with Rotary Control Switch - PWM Dimming for 12-24V LEDs, Fully Waterproof, Dimming Up to 4.8A at 12V or 2.4A at 24V: Car, Automotive, Marine, Low Voltage Under Cabinet Lights by Ryan Marx

Special Features: Two handles included, one silver and one black. The quality of the leads is good, sufficiently long and with silicone-like insulation. The illustrated wiring guide is easy to follow (the schematic style should be included for us old electricians and others who prefer schematics too). The knob turns smoothly and easily (as long as you don't push too hard on the spline shaft when installing through a thicker panel). ). The LED goes from dim to full brightness. (Note that there may be a threshold voltage where the knob moves slightly before the LED dims - this is a function of the LED, not the dimmer.) It comes in a small presentation box with a magnetic closure. Eliminate the packaging frills and reduce the price by around 20%. In the interest of full disclosure I would buy it again if I needed another.
