When purchasing LED strip bags (often used for portable lighting or decorative storage), you must prioritize IP Rating (e.g., IP65 or IP67) if the product is intended for outdoor or humid environments. Ensure the LED density (LEDs per meter) meets your brightness requirements and verify the heat dissipation capabilities of the bag material to prevent melting or fire hazards. For power, check if it uses USB 5V, Battery Pack, or DC 12V/24V inputs to ensure compatibility with your target market's infrastructure.
