Enter the intensity of the light (lux) into the Grow Light Distance Calculator. The calculator will evaluate and display the Grow Light Distance. 

Grow Light Distance Formula

The following formula is used to calculate the Grow Light Distance. 

Dgl = L / 12.088

  • Where Dgl is the Grow Light Distance (inches)
  • L is the intensity of the light (lux) 

How to Calculate Grow Light Distance?

The following example problems outline how to calculate Grow Light Distance.

Example Problem #1:

  1. First, determine the intensity of the light (lux). 
    • The intensity of the light (lux) is given as: 955.
  2. Finally, calculate the Grow Light Distance using the equation above: 

Dgl = L / 12.088

The values given above are inserted into the equation below and the solution is calculated:

Dgl = 955 / 12.088 = 79 (inches)

Example Problem #2: 

For this problem, the variables needed are provided below:

intensity of the light (lux) = 1500

This example problem is a test of your knowledge on the subject. Use the calculator above to check your answer. 

Dgl = L / 12.088 = ?
