Hi JoséHempSeed:
1 foot candle does not = 1 lumen
1 foot candle = 12.6 lumen.
What I'm trying to say is that what my meter measures 1" from the bulb won't be the same over 1 sq.ft. unless the light is also 1sq.ft. Since the bulb is not 1sq.ft. you are going to have a diminishing amount of light towards the outer edge of the 1sq.ft. you are measuring.
Make since.
Later.
