The same power of cob and led lamp which is brighter
LED lamp now single lamp and COB of useful products, according to the principle of the photosynthetic efficiency can distinguish under the same power that or bright.
Taiwan chip is commonly used in single chip LED photosynthetic efficiency (commonly known as the single lamp) : 80 ~ 110 lm/W, under the same power chip, the greater the size (area) the higher light efficiency.
General use Taiwan chip COB light efficiency: 65 ~ 80 lm/W, the greater the power light efficiency is lower.
