## Description

Product description SUPERNIGHT LED Light Strip Dimmer This product has maintained the first sales of the same type of products since 2018. Recently, there are many problems about this product, we unified inspection and investigation. The following is the answer to the quality questions related to this product. Controller for Single Color LED Lights 12V/24V DC 30A LED PWM Dimmer With automatic memory function Weight: 90 g; Input: DC 12-24 V Size:66 mm (L) x 61 mm (W) x 20 mm (H) Material: metal and plastic Output: 1 Channel 360 W 12-24 V (0-30 A), 360 W-720 W Not suitable for multi-color mix Bonded LED lamps (such as RGB lamps / lamps, table lamps, fans, energy saving lamps, incandescent lamps, etc.) Please turn off power before installing this dimmer in case of electricity shock ( 12v dimmer switch control mode is knob-operated control) Why do products sometimes make noise? When the position of the wire head is not connected to the screw of the dimmer in place or the poor power supply on the market is used to connect the product, it will cause a large current sound (that is, noise) during adjustment. When you connect the dimmer, power supply and LED light, please ensure that the number of volts of the light and power supply is the same, otherwise the following bad effects will appear When the 24V power supply and 12V light are connected to the dimmer at the same time, the light strip will have bright, but it cannot be adjusted and will break the light strip; When the 12V power supply and 24V light strip are connected to the dimmer at the same time, the light will not shine. These two situations are caused by the mismatch between the light strip and the power supply, which has nothing to do with this product, please replace the appropriate light strip or power supply (this page only sells dimmers, if necessary, you can consult our service team). After selecting the appropriate power supply and lamp belt, please note that it is connected to the correct position, otherwise the following bad effects will appear When the line of the lamp belt and the line of the power supply are connected to the opposite position of the dimmer (IN/OUT), the lamp belt will not shine and will not work; When the positive and negative electrodes of the power supply or the positive and negative electrodes of the lamp belt are reversed, the lamp belt can shine, but the dimmer can not be adjusted. Check whether the above two cases are correctly connected.

Review: effective but note this - Good quality item with easy to wire terminals. The adjustability is great and handles a heavy load up to 30 amps. I'm using it to light some off road LED pod light but I do not have any spec on the lights (typical China stuff :( ). There is one BIG thing to note depending how you use this dimmer. It varies the negative side of the circuit. The application I utilized made this a challenge trying to use it in a HI/LOW light circuit. I preset the dimmer to be set for a dimmed lights on "low beam" switch mode. In "high beam" switch mode bypasses the dimmer and applies the -12v to the lights. The HI/LOW switch was designed to switch the +12 dc for the LED switch status; I had to get creative to make it work. If you just use as a LED dimmer, no issues, it will work great.
Review: Works well and easy to install. - Very pleased with the unit. I used it to dim the led bulbs on a triple set of aftermarket gauges in a custom console built for a 1978 bronco.

## Questions & Answers

**Q: Could someone tell me the frequency that this dimmer's pwm module operates at? my eyes are susceptible to led flicker. 60hz would be way too slow.**
A: I just measured mine with an oscilloscope. It switches at 1200 Hz, which is lower frequency than I would’ve expected for a PWM switch. The minimum on period is about 5%, and the maximum is about 92%. Mine has a voltage drop (PWM +Mosfet RDSon) of approximately 1 V with a 14 amp load. it is probably in excess of 1.5 V at it’s rated load (30A). I use a Meanwell 15 volt 200 watt power supply set to 13.2 volts to get full brightness from my 12 V / 14 amp LED string. If you go this route, the voltage adjustment is a small potentiometer next to the terminal block on the power supply.

**Q: Will this work on a 18 w 12 v led light?**
A: Yes and these dimmers work very well. I have 2 of them and they control 50 ft. of lights each. They are very "smooth" in dimming. Not all jumpy like others..

**Q: will this work with a. 12volt / .5 amp led singl light??**
A: I would think so.

**Q: I wire from the battery to the "in" side and to the lights (strip led) on the "outside" of the controller. Works once then it won't dim?**
A: I would send it back. Must be defective. Mine work fine

Very pleased with the unit. I used it to dim the led bulbs on a triple set of aftermarket gauges in a custom console built for a 1978 bronco.

### ⭐⭐⭐⭐⭐ Nice lamp upgrade, for much less than replacing the lamp.
*by J***Y on January 29, 2026*

This lamp had a flaky, mostly-broken touch switch on it. I couldn't use it with a smart outlet because its default setting was OFF when plugging it in, so turning on the outlet didn't turn on the light. It was also hard to turn on manually. When I finally found the right spot on the chassis to touch, it didn't remember my last brightness setting and came on full blast. Lame. Enter: this dimmer! I yanked the touch switch and controller PCB out completely, connected the 4 wires (+/- IN from the power cable, +/- OUT to the light rings) to the terminals on this dimmer, and stuck it to the lamp with a double sided adhesive pad. Bada-bing bada-boom! Now the light comes on to wherever I last physically set the knob as soon as I turn on the smart outlet. The knob is a great size to be easy to use without fumbling around whenever I do want to adjust it, and now I have continuous dimming from zero to 100%, instead of 3 janky settings. $12 to upgrade/revive an otherwise nice lamp. I'm no electrician, but it was a super easy mod. The terminals are stable and just big enough to be easy to work with, the knob feels solid and turns smooth, light doesn't flicker, and the box is nice and light for easy mounting. Easy-peasy.
