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.
