I. Requirements Analysis:

In scenarios such as nighttime searches, high-intensity illumination, or work site lighting, a versatile, reliable, and portable spotlight is a critical tool for enhancing safety. It must not only deliver sufficient brightness but also offer multiple light modes to adapt to varying needs, while maintaining continuous operation for extended periods to ensure stable illumination even in complex environments.

II. Product Features:

1. Multi-Function Lighting Design: This product features three lighting modes—Work Light, High Beam, and Strobe—to meet diverse illumination needs across various scenarios. The Work Light mode is suitable for routine tasks or general lighting, the High Beam mode is ideal for nighttime searches or long-distance illumination, while the Strobe mode can be used for warning signals or distress alerts.

2. Real-time battery level monitoring: Users can check the battery charge level at any time, enabling timely recharging to prevent work delays or safety issues caused by low power.

3. High Power and Long Battery Life: Power output ≥12W ensures bright illumination; battery capacity ≥4000mAh provides continuous operation for ≥20 hours, meeting extended working demands.

4. Portable Handheld Design: Featuring a lightweight, handheld design for easy carrying and mobility, ideal for outdoor operations or night patrols.

5. Safe and Reliable: Constructed from robust, durable materials with waterproof and dustproof design, ensuring stable operation in all harsh environments.

III. Application Scenarios:

1. Nighttime Search: During nighttime search and rescue operations, exploration, or patrols, the multi-functional handheld spotlight provides sufficient illumination to help users quickly locate targets.

2. Work Site Lighting: In factories, warehouses, and other work environments, this product can be used to provide task lighting or high-intensity illumination, ensuring operational safety and efficiency.

3. Safety Alert: In emergencies, the strobe mode can be used to emit warning signals, alerting nearby personnel to safety hazards or prompting rescue efforts.

IV. Technical Specifications:

Serial Number	Project Name	Technical Specifications
1	Standard	Complies with GB 30734-2014 and GB/T 15211-2013 standards. Explosion-proof performance shall meet the requirements of GB 3836.1-2010.
