I suspect whoever was responsible for the text on the flashlight isn’t a native English speaker either. :laughing:
My guess: I’ve seen LEDs referred to as ‘beads’ in Aliexpress listings, so perhaps ‘purple bead’ was a machine translation of ‘(ultra)violet LED’, and then a typo turned it into ‘purple beard’.
I like it - it gives the flashlight a bit more character. :laughing:
