Because it involves many factors, such as the inverse square law, installation height, beam angle, reflection and absorption, and uniformity requirements. Therefore, it's very complex, and it's not possible to explain all the details here. However, these factors contribute to a total discrepancy of about 12.9. This means that if you know the area and purpose of your space but are unsure about the number and type of lights you need, you might use the following formula to calculate the number of lights required:

Required Number of Lights=Lumen Output per Light (Model)Illuminance (Lux)×Area / Lumen Output per Light

 

Sure, let's calculate the number of lights needed for your space using the provided formula.

1. Convert the area from square feet to square meters (since lux is typically measured in metric units):

$\text{Area}=50\text{ ft}\times 100\text{ ft}$=5000 ft²

2. Use the provided formula:

 Required Number of Lights=Lumen Output per LightIlluminance (Lux)×Area/Lumen Output per Light​

Assuming the required illuminance for a store is 50 FC (500 lux) (a typical value for commercial spaces):

$\text{Illuminance (Lux)}=500$

$\text{Area}=\; 5000\; ft²$

$\text{Lumen Output per Light}=32000\text{ lumens}$

Now, plug in the values:

$\text{Required Number of Lights}=\frac{50\text{ fc}\times 5000{\text{ ft}}^{\mathrm{²}}\mathrm{}}{32000\text{ lumens}}$

 

Now, a space of 100ft long and 50ft wide requires that each cubic meter of light can reach more than 500lux, and the number of lights required is:  

10 or 12

If your house is over 20ft tall, you may need 12 lights,

 The actual situation is arranged according to the distance between the lamps, and only 10 or 12 lamps are used.
