One footcandle ≈ 10.764 lux. The footcandle (or lumen per square foot) is a non-SI unit of illuminance. Like the BTU, it is obsolete but it is still in fairly common use in the United States, particularly in construction-related engineering and in building codes.

Light bulb packages in the US read in lumens, as do bulb sites 1000bulbs.com and hydro shops equipment, most of the lighting guides on here, etc., yeah?

Actually, come to think about it, just about any time I see any measure of light relating to cannabis it is in lumens...



i kno. i live in the us, but lumins are a mesure of light in a square foot or meter and you cant convert a foot candle into a lumen
+ you wont find an accurite light tester that shows lumens (but of shit ones that do),
