Default LED and lumens

I spent a couple of minutes this afternoon in my bulb store. On LED only a subset of one brand indicate the lumens of their LEDs. They were all 1W and composed of 20 LEDs. Here they are :
  • yellow : 7-10 lm
  • green : 30-45 lm
  • red : 8-12 lm
  • blue : 7-10 lm
  • white : no stock...
  • multiple colors : no stock...
I was also surprised to see so much difference... I simply copied what was written on the packaging.

Denis.
