R4 R Series Constant Voltage Receiver
Product Code: R4
1. Automatically adapt to LED light, which works from DC12V to 24V.
2. The receiver can be compatible with our 5 different functions remote control or 2.4G wireless controller to realize functions such as dimming, RGB/RGBW, and color temperature control.
3.10 strobe and fade change modes, with 4096 grey scales per channel, the LED lamp is richer and vivid without flash.
R4 R Series Constant Voltage Receiver Overview
The R4 R Series receiver takes a wireless control signal and outputs constant-voltage PWM to drive DC12V-24V LED strips in single-color, CCT, RGB or RGBW. It ships as the receiver only — pair it with one of our RF remotes or touch panels to build a complete wireless dimming kit.
Two radio versions are available: the R4-433M (433MHz) works with the T-series wireless remote, while the R4-2.4G works with the PX-series touch panel controller. Confirm the radio of your remote before ordering so the pair links up.

Which R4 Variant or Receiver Do You Need?
- R4-433M (this receiver) — you already have a T-series RF remote or want to drive a 12-24V constant-voltage strip with one.
- R4-CC constant current receiver — your strip is a constant-current type; pick the CC sibling so the output matches the driver.
- BC-R4-WP waterproof controller — you need a sealed RGBW controller for damp or outdoor installation.
- Receiver + remote bundle — if this is a first-time install, the T1-T5 & R4 wireless remote controller page covers the paired kit in one order.
