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×12.9

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):

$1\text{ square foot}=0.092903\text{ square meters}$ $\text{Area}=50\text{ ft}\times 100\text{ ft}=5000\text{ square feet}$ $\text{Area in square meters}=5000{\text{ ft}}^2\times 0.092903{\text{ m}}^2\mathrm{/}{\text{ft}}^2=464.515{\text{ m}}^2$

2. Use the provided formula:

$\text{Required Number of Lights}=\frac{\text{Illuminance (Lux)}\times \text{Area}\times 12.9}{\text{Lumen Output per Light}}$

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

$\text{Illuminance (Lux)}=500$ $\text{Area}=464.515{\text{ m}}^2$ $\text{Lumen Output per Light}=32000\text{ lumens}$

Now, plug in the values:

$\text{Required Number of Lights}=\frac{500\text{ lux}\times 464.515{\text{ m}}^2\times 12.9}{32000\text{ lumens}}$

Calculate the numerator:

$500\times 464.515\times 12.9=2996347.5$

Now, divide by the lumen output per light:

$\frac{2996347.5}{32000}\approx 93.64$

So, you would need approximately 94 lights to achieve 500 lux in a store with an area of 50 ft by 100 ft.

 The actual situation is arranged according to the distance between the lamps, and only 91 lamps are used.
