The double-sided layout removes side shadows and creates smooth omnidirectional glow inside milky/transparent 40mm tubes. It works with SPI controllers, SD players, Art-Net and DMX-to-SPI decoders. Ideal for stage tubes, 3D pixel matrices, bar ceilings, atrium suspensions and architectural outline lighting.
True RGBW Output: SMD5050 RGBW + UCS2904 enables pure white, warm/cool white and advanced color mixing.
Double-Side 17.5mm FR4 Board: 72 LEDs per side, 144 LEDs/m, 360° illumination with no dead angle.
24 Pixels/m: 6 LEDs + 1 UCS2904 per segment, supports flowing, gradient, comet, video-mapping effects.
Stable DC24V System: Lower current than 12V pixel tubes, better for long runs and engineering installs.
Cloud-Tube Optimized: Matched to 40mm PC tube housing; SPI/DMX/Art-Net controller compatible.
