Buying Guide for LED Lights: Top Tips for Outdoor String Lights
The Science Behind LED Strips
Modern LED strips use Surface-Mounted Device (SMD) technology, with chip types like:
2835 SMD: Balance of brightness and efficiency
5050 SMD: High output for RGB applications
COB (Chip-on-Board): Seamless, glare-free illumination
