- COB chip with protective gel — uniformly injected light, without bright spots, ideal for fixtures with lenses or diffusers
- Integrated aluminum heat sink — efficient thermal dissipation without additional accessories, compact 35mm diameter
- Compatible with a wide range of applications — from household light fixtures and spotlights to illuminated signs, machinery, and DIY electronic projects
- Lifespan of up to 10,000 hours — economical replacement component with low wear over time
How it works and how to install it
The 35mm COB LED module features an integrated control circuit that allows direct power supply from the 220V AC mains, eliminating the need for an external driver. Connection is made via the two contacts marked L (live) and N (neutral) on the aluminum board. Due to its small dimensions (35mm diameter, 2.46mm total thickness) and the mounting slots of the heat sink, the module integrates directly into the standard receptacles of compatible light fixtures. Installation must be performed exclusively by authorized personnel, with appropriate protective equipment, as the module operates at a dangerous voltage of 220V AC.
