Your average 60 watt household light bulb produces 650 to 700 lumens when burned under standardized conditions.
Therefore you can estimate that a 60 watt household light bulb, burned under average household conditions might produce somewhere between 50 and 55 candle power, give or take….
How many watts is a foot candle?
You can also calculate the number of watts directly from the foot-candles by combining both equations and using the following: Watts = Foot Candles x 0.01609696 This is because 10.76 x 0.001496 = 0.01609696).

How many lumens is a Lux?
One lux is equal to one lumen per square metre: 1 lx = 1 lm/m2 = 1 cd. sr/m2. A flux of 1000 lumens, spread uniformly over an area of 1 square metre, lights up that square metre with an illuminance of 1000 lux.
How strong is 100 lumens?
100 lumens is considered bright enough for most walkways — including commercial properties. 100 lumens is equivalent to about 20 watts.

How many foot candles are in a 100 watt bulb?
400 foot candlesTheir efficiency is in the range of 4 lumens per watt. This means that a 100 watt bulb will generate 400 lumens – TOTAL. (Here’s the big leap) Now, if we COULD reflect all of that 400 lumens onto 1 square foot we would get a light intensity of 400 foot candles.
Is 3000 lumens too bright?
In other words, 3,000 lumens is meant to give a room a brighter light. This is not ideal if you have a small room and it’s a bedroom. You don’t want to blind your eyes when you’re about to go to bed. On the other hand, 2,000 lumens is ideal if you wish to light up a 200 square-foot living room.

How many foot candles does a monstera need?
Medium light intensity plants prefer 250 to 1,000 foot-candles. Best growth occurs above 750 foot-candles unless plants also receive extended periods of direct sunlight.
