Xenon bulbs run with an ac inverter
- globular-toast 2y agoInteresting. I didn't know that. Looking around online it seems they run at a frequency around 250-300Hz which may be noticeable. I notice it more when lights are far away and in my peripheral vision. I assumed they were LEDs because I've definitely noticed it with LEDs but I guess they could be xenons too.
