COB LED lights, unlike SMD LED lights, cannot be utilized to make color-changing lamps or lights. That is due to the fact that there are only two contacts and one circuit. To achieve the color-changing illusion, several modification channels are needed. COB LED lights are hence effective in single-color applications.
COB concise process minimizes failure factors and contributes to higher stability, larger heat dissipation area reduces chip overheat damage and extends the lifespan of LEDs.
