1. Purpose:
Indoor: Choose low-voltage LED light strings (such as USB powered or battery powered) to avoid heating issues.
Outdoor: Identify waterproof rating (IP65 or above), UV protection and high/low temperature resistance are required.
2. Type:
LED light string: energy-saving, long lifespan, available in colorful or warm white light.
Shaped light string (stars, snowflakes, spheres, etc.): suitable for theme decoration.
3. Length and spacing:
Measure the size of the decorative area and select the length of the light string (e.g. 5 meters, 10 meters).
The spacing between light bulbs (such as 10cm/20cm) affects compactness, with small spacing suitable for wrapping around trees and large spacing suitable for hanging.
