Wouldn't power cycling your bulbs like that lower their longevity?

- hexa22 5y agoNo. These things are designed to turn on and off hundreds of times per second to emulate dimming.
- adrianmonk 5y agoOr even tens of thousands of times per second, according to an Analog Devices article: "Don’t Want to Hear It? Avoid the Audio Band with PWM LED Dimming at Frequencies Above 20kHz" (https://www.analog.com/en/technical-articles/avoid-the-audio-band-with-pwm-led-dimming.html https://www.analog.com/en/technical-articles/avoid-the-audio...).
- vel0city 5y agoThe part that wears out from cycling often is the ballast of the bulb. I imagine these smart lights are in the bulb's ballast, so sending the "off" command isn't de-energizing the ballast of the lightbulbs. If you were doing it on a smart light switch that was feeding 120V to the ballasts I do imagine it would impart some additional wear and tear to the bulbs. I'm not sure how much additional wear and tear it would be on an LED, I know the main thing that wears out on a florescent is the starting circuit which needs to bring the energy of the bulb enough to start the arc which wears out over time.
- stavros 5y agoIt's very odd to me that bulbs don't come in two parts: Ballast and LED. That way, we wouldn't have to keep buying and throwing away the perfectly good part when the other one broke.
