One guy bought over 4 thousands LED lamps over years, meticulously measured their actual specs and made a huge online catalog https://lamptest.ru/
I follow his project a bit and it looks like consumers are really at loss. Generally there is no reliable way to choose a good led lamp without consulting such catalog. Lamps packaging often lies about actual specs, lamps with the same packaging but manufactured in different years might have different quality etc
