Question: how dimmable are led lights?
Answer: In the case of PWM, dimmable LEDs work by creating a dimming effect. Unlike traditional lighting such as incandescent, dimmable LED bulbs don't rely on voltage to dictate their level of brightness. ... For example, if you have dimmed your lights to 10%, they will be 'on' for 10% of the time and 'off' for 90%.
