BTF-LIGHTING Single Color CCT RGB RGBW 4 Channel Signal Amplifier Controller Work with 2PIN 3PIN 4PIN 5PIN DC12V/DC24V Max 24A 5050SMD LED Strip Suitable for Long Distance Light Projects

Device amplifiers with seemingly perfect color replication. I tested controller led strip amplifier strip., controller led strip, amplifier led strip led strip, controller amplifier led strip led strip. I tested RGBW all individual color channels, and any issues my testing. I noticed no dimming in the chain so long as only three strips were used with the max two recommended be powered by the amplifier.

Installed for several months and have had no issues.

Worked as it was intended. Good quality product and allowed me to control brightness.

Product worked fairly well and the color of the LED tape going in matched the LED tape coming out. Can only give 4 stars though because there is about a half-a-second delay in the blue LEDs that come out of the amplifier, making it not ideal for lighting design or any application where the colors need to change abruptly/in time with music/etc. When all of the colors are on and then are suddenly switched off, the blue diodes stay on for a solid half second; and they have the same 0.5 second delay when trying to switch all the colors on abruptly. Half a second doesn't sound like much but it's definitely noticeable. If you sing "happy birthday" the timing difference is about equal to the "too you" part, with the red/green/white diodes switching off at "too" and the blue diodes switching off at "you."

I bought this in the hopes that it would serve as a means to control an analog white LED strip that was 24v with WLED. It did not disappoint. This allowed me to power the microcontroller separately from the LED strip while controlling it with a GPIO pin (3.3v) because it has an optocoupler that keeps the supply and LED strip voltage separate from the input (controller) signal. I know at least the version I got has the optocoupler. YMMV. If I was controlling RGB or RGBW (3 channel or 4channel) I'd also gamble on the 4channel version from BTF lighting. This use case is documented in the WLED guide on the website - but if there's no optocoupler the amplifier won't work for this use case.

These 1 channel signal amplifiers are pretty basic. You send in signal voltage on 1 side and it should at the very least send it out the other side of your connection. I ordered 3 none of them made a connection ag all... nothing. Bad quality control on the manufacturer end...I'm not even going to buy from this seller anymore either.

Works, but not well. The repeated signal clearly differs from the controller, resulting in the amplified half of the LEDs taking an obvious different hue. It especially struggles with red, and at brightnesses under 30% it’s pretty much useless. The “LDIGITECH Miboxer” product here worked much, much better for me.

Easy and simple to install and does the job at affordable price.

Un amplificador de muy buena calidad
