The SHIYUAN LUNA represents a class of high-lumen output, all-in-one solar flood lights designed for commercial-grade area illumination. The "2000W" denotes an exceptionally high brightness equivalent, making it suitable for lighting very large areas such as parking lots, sports courts, and industrial yards. Its integrated design and focused solar panel are built for ease of installation and autonomy from the electrical grid.

Key Features & Technical Specifications

Optical System & Luminosity

2000W Halogen Equivalent: Utilizes high-efficiency, high-lumen LED chips to produce an intense light output comparable to a traditional 2000-watt metal halide or halogen floodlight. The actual power consumption of the LED array is a fraction of this (see below).

Wide-Angle Flood Optics: Designed with lenses or reflectors to provide broad, uniform illumination over a very wide area (e.g., 120-degree beam angle), eliminating dark spots. The "Luna" name suggests a focus on area lighting rather than spot lighting.

Adaptive Lighting Modes: Commonly features multiple operating modes such as Dusk-to-Dawn (full brightness all night), Motion-Sensing (dimmed standby brightness that triggers to full power upon detection), or a hybrid Smart Mode (all night at a dimmed level, triggering to full brightness with motion).

Solar Power & Energy Management

28W Monocrystalline Solar Panel: The integrated panel is responsible for charging the internal battery. A 28W panel is sizeable for an all-in-one unit but must be evaluated in the context of the massive light output it needs to support.

Integrated Lithium Battery: Contains a substantial lithium-ion phosphate (LiFePO4) or high-quality Li-ion battery pack. This battery must have a high capacity (estimated 20,000-30,000mAh or more) to store enough energy for nightly operation.

Intelligent Controller (IC): The core of the system. It manages:

Maximum Power Point Tracking (MPPT): Optimizes the energy harvest from the solar panel, increasing efficiency by up to 30% compared to PWM controllers.

Automatic On/Off: Activates the light at dusk based on a built-in light sensor.

Protection Circuits: Includes overcharge, over-discharge, and short-circuit protection to safeguard the battery and LEDs.

Build Quality & Warranty

IP67 Rated Enclosure: Offers superior dust and water resistance, capable of withstanding temporary immersion. This is essential for a fixture exposed to the elements year-round.

Robust Heat Sink Design: Critical for dissipating the heat generated by the high-power LED array, ensuring longevity and preventing lumen depreciation.

1-Year Limited Warranty: Covers manufacturing defects for one year. The warranty duration is a key consideration for the integrated battery, which is the component most susceptible to degradation over time.

Target Applications

Commercial & Industrial Security: Lighting large perimeters of warehouses, factories, and storage yards.

Public Area Lighting: Illuminating parking lots, community parks, sports courts, and bus stations.

Construction Site Lighting: Providing broad, powerful light for nighttime work and site security.

Agricultural and Farmstead Lighting: Lighting large barnyards, equipment yards, and greenhouse areas.
