Project: City plaza main pool with pixel-chasing RGBW musical fountain.

1.Model & Quantity: SYA-501-12W-RGBW-DMX × 64 fixtures (co-axial nozzle type)

2.Electrical: DC24V; groups of eight per power branch; IP68 submersible junction boxes with quick connectors; UV-resistant seals.

3.Optics: Ring distribution optics; RGBW 4-channel, SDCM ≤ 3 for color consistency.

4.Installation: Co-axial nozzle seat with φ45 mm hole; point spacing 0.8 m; anti-water-hammer reinforced structure; 8 mm tempered glass.

5.Control: DMX512/RDM; console-programmed 16 shows (chase, breathe, rainbow, festival presets).

6.Acceptance Metrics: Base of water column ≥ 1200 lx; imperceptible color-switch latency; synchronization deviation < 30 ms.

7.Outcome: Precisely synchronized color with music tempo; high visibility from a distance; safe low-voltage SELV for public interaction.
