Use this calculator to figure out how many lights to use in your grow room. * To use this calculator, you must know the lumen rating of the lights you plan to use.How long is the grow room? ft How wide is the grow room? ft Square Feet sq ft Lumens Required TO lumens How ...
The illuminance Ev in lux (lx) is equal to 10.76391 times the luminous flux ΦV in lumens (lm) divided by the surface area A in square feet (ft2):Ev(lx) = 10.76391 ×ΦV(lm) / A(ft2)For a spherical light source, the area A is equal to 4 times pi times the squared sphere ...

Determine room size by square footage.Multiply the length times the width of the room to get the room square footage. For example, if the room is 10 feet wide and 10 feet long, the room’s square footage will be 100 square feet. Establish the footcandle requirement for your...
You can see that no direct conversion is possible for translating footcandles to lumens because these are not quite the same type of data. But if you remember that the only thing distinguishing them is whether it is a unit of flow in square feet or a strict amount, you can become adept...
illuminance in Lux lx Sphere Radius in Feet or Meters Calculate Reset Result Luminous Flux in Lumens lmConversion Equation Where 'r' is the radius of the sphere in feet. In case, If you would like to use meters instead of feet, then convert sq. feet to sq. meter. ie; 1 sq. mt. ...
To convert the Lux measurements to lumens, you multiply the average of all nine readings by the area of the image in square meters, or to write it as a formula: ANSI lumens = average of Lux readings X image area in square meters ...
how much lumen you need for the bulb to brighten up your room, firstly measure the room. Multiply the value of room width by room length, and you get the area of the room. For example, a room with 10×10 feet (width x length) gives the total area of the room 100 square feet. ...

1 lux is 1 lumen of light over 1 square meter. This measurement not only gives you volume but also proportion, a volume of light output but that volume in a defined space. Another alternative measurement for light that makes a bit more sense than lumens is candela sometimes referred to as...
