As an engineer who’s been in the LED lighting business for a long time this is meaningless as concerns real lighting for instance commercial lighting and the amount of lemons that you need
For your silly little TVs and iPhones and everything OK great
Most of the commercial world is dominated by Chinese garbage that fails nearly right out of the box or soon there after
Ringdale of Texas has the worlds greatest chips and drivers and has a 10 year no light loss warranty.
All commercial LED products are based on Nakamura is blue light laser which one of the Nobel prize in 1995
Why is this “meaningless as concerns real lighting”, if it is possible to direct more light outwards from the source? (Couldn’t it further impact electricity consumption, for example?)
