EXPERT’S GUIDE TO... LIGHT-EMITTING MITTING DIODES (LEDS)
They’re brighter, but how do they actually work?
‘White-light’ LEDS are actually at the ‘blue’ end of the light spectrum and were invented by three Japanese physicists in the 1990s who went on to win the 2014 Nobel Prize in Physics for their work. Compared to filament bulbs, LEDS don’t draw so much current, produce many times more light, last longer and are smaller than conventional bulbs. Industry standard for life-cycle is 50,000 hours per LED, or six years’ continuous use, and a single 10W LED can throw out an 800-ft beam that is a lot more intense than standard bulbs the closer you get to your bike.

LEDS can produce more intense, and longer, beams
