Could this be a difference in the dimmer. I’m in the US (120V vs 240V) and I had research carefully what dimmers were compatible with the dimmable LEDs in our flat. Sometimes the dimmer would hum, the LEDs would squeal, or they would go from 0 to 100% with 20% dimming.
Most LEDs are made in China and I doubt the Swiss are getting a specially manufactured ones. But old, incompatible dimmers are definitely a thing.
- pflanze 9y agoNo external dimmers were involved. As I wrote, I opened up a bulb myself (sawed off the tip of the base) and saw electronic parts consistent with a switch mode power supply (dozens of parts including rectifier, capacitor, tiny transformer, rectifier, capacitor, IC for controlling it). I know I saw something different than was in the video for the UK version! No reason China can't produce both.
- Zak 9y agoIt's not the LEDs themselves that are a problem there, but the driver circuitry in the "bulb"[0]. There are a fair number of these being made in the US and Europe, not just China. Significant numbers of LEDs are also made outside China - Cree manufactures LEDs in both the US and China; Nichia manufactures LEDs in Japan. [0] Bulb is not really an accurate term here. Maybe bulb-replacement?
