Applications

• Architectural Lighting: Fine-tuning LED cove lighting and under-cabinet kitchen setups.
• Automotive & Marine: Dimming 12V interior cabin lights in RVs, camper vans, and boats.
• Photography/Videography: Creating custom adjustable DIY LED lighting panels.
  Hobby Enclosures: Controlling the brightness of 3D printer enclosure lights or display cases.

Unlock New Capabilities

• Past Projects: If you've just been plugging your LED strips directly into a raw power supply, you're stuck with blinding 100% brightness that can wash out a room and shorten the lifespan of your LEDs due to constant heat.
  
• Feature Upgrade: Installing this inline dimmer unlocks precise ambient control. By lowering the duty cycle, you not only get the perfect lighting level but also significantly reduce the thermal load on your LED chips, drastically extending their lifespan.
  
• Effort Level: Beginner. No soldering required! All you need is a small Phillips-head screwdriver and a wire stripper to connect your power supply and LED strip to the terminal block.

Package Includes:

• 1 x Adjustable Dimmer Switch For Single LED Strip (12V-24V, 8A)

Frequently Asked Questions (FAQ)

• Can I use this dimmer for RGB or RGBW LED strips?
  No, this is a single-channel dimmer designed strictly for single-color (e.g., Cool White, Warm White, Blue) LED strips.
• What is the maximum wattage this dimmer can handle?
  It supports 8A. This equals 96W if you are using a 12V power supply, or 192W if you are using a 24V power supply.
• Does this dimmer cause flickering on camera?
  It uses high-frequency PWM to minimize visible flicker for the human eye. However, at very low dimming levels, extremely high-speed cameras might detect a slight strobing effect.
• Can I use this with a 5V LED strip?
  No, the internal circuitry is designed for an operating range of 12V to 24V DC.
• How do I turn the lights completely off?
  Turn the rotary knob fully counter-clockwise until you hear and feel a tactile "click." This completely cuts the power.
• Can I dim AC household LED bulbs with this switch?
  Absolutely not. This is a low-voltage DC PWM controller. Connecting it to AC mains will destroy the unit instantly.
• Why is my dimmer enclosure getting hot?
  If it is getting excessively hot, you are likely exceeding the 8A continuous load limit, or your terminal screw connections are loose causing resistance. Ensure tight wiring.
• Is the dimmer switch waterproof?
  No, the housing is not sealed. It is designed for indoor, dry-location use only.
• Can I control a DC motor's speed with this module?
  While technically a PWM module, it is optimized for resistive LED loads. Using it with inductive loads like motors without a flyback diode may damage the controller.
• Do I need a soldering iron to install this?
  No, the module features a convenient 4-pin screw terminal block for easy wire insertion.
• Can it run two separate LED strips at the same time?
  Yes, as long as they are wired in parallel into the OUT terminals and the combined current draw does not exceed 8 Amps.
• Does this dimmer make a high-pitched whining or buzzing noise?
  A high-quality PWM circuit itself is usually silent. If you hear a buzz, it is typically coming from a cheap or under-rated power supply struggling with the PWM frequency.
