1. This strip is 12V UCS2904 4 channel RGBW 60 led digital strips that different with DMX512 RGBW led pixel strips. Actually the protocol is compatible with SK6812 RGBW led tape. 2. Compared to the integrated SK6812 RGBW ones, this external IC chip 12V 144 pixels RGBW LED strip has much higher brightness and much stability. 3. 12V RGBW 144 pixels led strip have following advantages that digital RGB led pixel strips do not have. .Presence of white LED allows for higher brightness and more color mixing options. .4 colors LED allowing for tones that were previously hard to achieve with single RGB strip. .White and RGB can be independently controlled to allows us to create bolder and more vibrant colors than with RGB alone. 4. Entire one meter strip has 48 pixels ( 192 channels), 144 pcs RGBW leds on 15mm width pcb board. 5. There are Warm white 2700K, Neutral White 4500K, Cold white 6500K white CCT to choose. 6. The strip is made of flexible PCB material, you can cut this stuff pretty easily with wire cutters, there are cut-lines every 3 LED. Solder to the 0.1" copper pads and you're good to go. 7. If the 12V UCS2904 RGBW pixel led strip does get damaged, it is often one pixel copper unit broken, in such case, cutting of this copper unit segment and resoldering the rest copper units together brings the strip back to life. 8. Widely used in entertainment, stage,live performance like 3D effects and TV shows, etc. 9. 12V 144 pixels RGBW LED digital pixel tape is offered in both waterproof and non-waterproof versions allowing for both indoor and outdoor applications.
