This document is a user guide for the Ustellar Smart LED Flood Light, model UT88875-RGBW. It provides comprehensive instructions for installation, pairing with the Smart Life app, and controlling the light using Amazon Alexa and Google Assistant.

The Ustellar Smart LED Flood Light is designed to provide smart lighting solutions, offering both traditional manual control and advanced smart control features. The system is built around the Smart Life app, which acts as the central hub for managing the flood lights. Once connected to the app, users can control the lights remotely, adjust settings, and integrate with voice assistants for hands-free operation.

Function Description:

The primary function of the Ustellar Smart LED Flood Light is to provide customizable illumination for outdoor spaces. It features RGBW (Red, Green, Blue, Warm White) color capabilities, allowing users to select from a wide spectrum of colors and adjust the color temperature to create different ambiances. The flood light is designed for both general illumination and decorative lighting, with various preset scenarios available through the Smart Life app.

The smart flood light system operates on a 2.4GHz WiFi network, ensuring compatibility with most home networks. The WiFi signal receiving module is integrated into the first flood light head, which is positioned closest to the power adapter, optimizing wireless connectivity. The system supports multiple flood lights, allowing users to create a synchronized lighting setup for larger areas.

Usage Features:

The Ustellar Smart LED Flood Light offers a range of usage features, making it versatile and user-friendly:

Installation Flexibility: The guide outlines two main installation scenarios. Users can either mount the flood lights on a panel using screws or attach them to ground sticks for placement in soft ground like gardens or lawns. The adjustable bracket allows for precise control over the lighting direction, enabling users to illuminate specific areas as needed.
Smart Life App Control: The core of the smart functionality lies within the Smart Life app. After a straightforward pairing process, users can:
- Turn On/Off: Remotely switch the lights on or off from anywhere with an internet connection.
- Color Adjustment: Choose from a vast array of RGB colors or select warm white light.
- Brightness Control: Adjust the intensity of the light to suit different moods or tasks.
- Scenario Selection: Utilize pre-programmed lighting scenarios like "Flow," "Rainbow," "Chase," "Dazzle," and "Gradient" for dynamic lighting effects.
- Individual or Group Control: The app allows users to control each flood light individually or group multiple lights together for synchronized control. This is particularly useful for managing larger installations where consistent lighting across several units is desired. Grouping lights also enables synchronized color changes and effects.
Voice Control Integration: The flood light seamlessly integrates with popular voice assistants, Amazon Alexa and Google Assistant, providing a hands-free control experience:
- Amazon Alexa: Users can link their Smart Life account to Alexa, discover the flood lights, and then use voice commands to turn them on/off, change colors (e.g., "Alexa, set 'smart light' to 'blue'"), and adjust brightness (e.g., "Alexa, set 'smart light' to '50%'"). A simple, recognizable name for the light is recommended for easier voice recognition.
- Google Assistant: Similar to Alexa, the Smart Life account can be linked to Google Assistant. Voice commands can then be used to control the lights, such as "Ok Google, turn on 'device name'" or "Ok Google, set 'device name' to 'color'."
Rapid Blinking Status for Pairing: The light features a rapid blinking status, activated by a specific on-off sequence (3 times), which indicates it's ready for pairing with the Smart Life app. This visual feedback simplifies the connection process.
Waterproof Design: The flood lights themselves are rated IP66 waterproof, making them suitable for outdoor use and resistant to rain and damp conditions. However, it's important to note that the power adapter is IP44 and requires protection from direct outdoor exposure, either by connecting to an indoor socket or using a waterproof box.

Maintenance Features:

While the manual does not explicitly detail "maintenance features" in the traditional sense, it provides important guidelines and warnings that contribute to the longevity and safe operation of the device, which can be considered aspects of maintenance:

Pre-Installation Check: Users are advised to check if the light and its components are intact before installation, preventing issues from damaged parts.
Power Disconnection During Installation: Emphasizing safety, the guide instructs users to cut off power before installation to prevent electrical hazards.
Environmental Considerations:
- Corrosive Conditions: Users are warned not to place the light in corrosive conditions, which could degrade materials and reduce lifespan.
- Heat Dissipation: The light should be used in conditions that allow for good heat dissipation, with a recommended working temperature of less than 45°C. Excessive heat can lead to lumen depression and shorten the light's lifespan.
- Water Immersion: Although the flood lights are IP66 waterproof, they should not be immersed in water.
Cord Damage: In case of any damage to the power cord, users are instructed to immediately cut off power and stop using the light, highlighting a critical safety measure.
No Retrofitting: Users are explicitly told not to retrofit the light within the warranty period, ensuring that any issues are handled by authorized service and preventing potential damage from unauthorized modifications.
Voltage Compliance: The guide stresses the importance of using the voltage indicated on the packing to ensure proper operation and prevent damage.
Mounting Position Strength: The mounting position must be able to bear at least 10 times the weight of the light, ensuring secure installation and preventing accidental falls.
Minimum Distance from Objects: A minimum distance of 1 meter between the light and illuminated objects is recommended to prevent high temperatures caused by short distances.
Non-Replaceable Light Source: The light source of this luminaire is not replaceable, implying that the entire unit would need to be replaced if the light source fails, which is a design consideration for long-term maintenance.

In summary, the Ustellar Smart LED Flood Light is a feature-rich outdoor lighting solution that combines robust design with smart control capabilities, offering convenience and versatility through its app and voice assistant integrations, all while emphasizing user safety and proper operational guidelines.
