Pre-embedded requirements: All internal wiring must be embedded with the framework to prevent structural damage. Use outdoor waterproof junction boxes (IP65 rating), and double-wrap the connection points with waterproof tape and insulating tape.
Debugging procedure: Test brightness and color consistency for each light → debug dynamic effects → record operational parameters → generate debugging report.
Lamp selection: Choose an underwater waterproof RGBW fountain light (IP68-rated) with 18-24W power, designed for water depths of 0.5-1.5m, featuring dynamic lighting effects synchronized with water jet patterns.
Installation method: Embedded in the fountain pool base, using stainless steel mounting brackets welded to the pre-buried components. The bracket height should be 5-10cm above the pool's sediment layer to prevent light obstruction.
Waterproofing: The cable uses a dedicated underwater sealing connector, runs through the conduit to the waterproof junction box at the pool edge, and is reinforced at the connector with specialized underwater sealant to ensure no leakage during prolonged immersion.
24W RGBW compact spotlight: Install 2-4 units along the base perimeter of each column, with spacing adjusted according to diameter (2 units for ≤50cm, 4 units for>50cm). Project 30-45° beams to ensure even illumination. Secure to ground or column base using stainless steel brackets with anti-corrosion treatment, fastened to the ground with expansion bolts.
Column-mounted lights: Flexible RGBW column-mounted lights are selected, installed by wrapping them around the column body at 15-20cm intervals, with stainless steel clips securing both ends (the clips feature anti-slip soft pads to prevent surface scratches). The light fixtures are waterproofed at the connection points, and the cables are discreetly routed along the column to the base junction box, creating a complementary effect with the floodlight beams.

Ideal for major local festivals or celebrations.
2.1.3.3.4 Installation and Usage Notes
Environmental adaptation: Egypt experiences frequent sandstorms. Prior to installation, remove impurities from the installation area. After installation, clean the light-transmitting cover once monthly. Avoid direct exposure of the lamp to intense sunlight. A sunshade may be added to prevent light attenuation.

2.2 Dynamic Effects and Playback Methods
2.2.1 Core Effect Types
Supports dynamic effects such as scanning, gradient, chase, jump, and music synchronization. To meet commercial center requirements, three preset basic modes are available: canopy spotlights, fountain lights, column lights, wall wash lights, and floor-mounted lights with synchronized control.
Daytime mode: The system employs warm-toned lighting (2700K-3000K) with constant low-intensity floodlights on the canopy. Column and pillar lights emit warm white light, synchronized with the fountain lights' soft illumination. RGBW wall washers provide uniform warm white lighting across the walls, while recessed lights offer supplementary warmth. This creates a sophisticated and dignified commercial ambiance, perfectly suited for daily operations.
Festival Mode: Features full-color dynamic effects with synchronized operation of canopy spotlights, fountain lights, column lights, and recessed lights. The wall washer creates RGB dynamic color cycles (gradients, chases, etc.) across entire walls, while pillar embrace lights and floodlights form three-dimensional colored effects. Fountain lights change colors with water column undulations. Customizable festival-specific light sequences are supported, automatically switching to energy-saving daily mode after 23:00.
Egyptian Flag Special Mode: The control software precisely replicates the red, white, and black colors of the Egyptian flag, with the wall washer lights synchronizing the flag's colors across the entire wall (as static vertical stripes or dynamic flowing effects). Other lights automatically switch to warm white light for enhanced ambiance. This mode is ideal for major local festivals and celebrations, highlighting the cultural relevance of the region.
Daytime mode: The space features warm-toned lighting (3000K) with low-intensity floodlights permanently activated. Both column and pillar lights emit warm white light, while fountain lights synchronize to create a soothing ambiance. This design cultivates a dignified commercial atmosphere, perfectly suited for daily operations.
Festival Mode: Switches to full-color dynamic effects with synchronized operation of canopy spotlights, fountain lights, and column lights. Features color gradients, synchronized chasing, and three-dimensional lighting effects created by pillar-hugging lights and floodlights. Fountain lights change colors with water flow. Customizable festival-specific light sequences are supported. After 23:00, it automatically switches to daily mode for energy-saving operation.
2.2.2 Playback Control Logic
The system supports scheduled switching (with minute-level precision) through preset effect sequences in the control software. The main controller stores over 10 customizable programs offline, eliminating the need for prolonged computer connections.
