This long but interesting ieee Spectrum article takes an in-depth – and very scientific – look at the mystery surrounding the drive to make our LED lamps more efficient. The problem, known as droop in the trade, means that LEDs cannot be manufactured to emit more light, because the output drops off significantly above a certain wattage. That’s apparently why most household LED lamps only go up to 20W or so. It’s a fascinating, albeit geeky, tale which shows how much science…
