          The confusion around whether COB (Chip-on-Board) LEDs require drivers is common. Without proper powering, their performance and lifespan can be compromised. This guide will clarify if drivers are necessary and why they matter for COB LEDs. Yes, COB LEDs typically require drivers to regulate the current and voltage supplied to them.
