I am electronic technician from Cuba, i repair led lamps and led bulbs. Usually it use 5.2V led, 7.2V and today discover E14 socket led bulb with 13V leds.. all measured using laboratory power supply.
I being searching for name or encapsulation for those 13V leds.. Can you help? Regards.

You are confusing lumens per chip and efficacy (lm/W). The data for 2016 series was taken from Cree J series datasheet. Of course, typical LPW is around 140-150.

It is only 3.2 sq mm, implying 62.5 lumen per sq mm. The best I know of are only 40 lumen per sq mm.
