RGB Strobe Ring
The primary colours of white light are red, green & blue
(RGB). The whitish glow of the ring is made up of fast
flickering red, green & blue LEDs. When you swing
your ring bearing hand in a circle, white light amazingly
‘separates’ into the three primary colours. Fascinating
to watch!
