As an expert in the field of lighting design, I understand the importance of selecting the right amount of lumens for a space to ensure adequate illumination and a comfortable environment. The number of lumens required per square foot is a critical factor in the calculation of the total lumens needed for a room.
To determine the lumens needed per square foot, you must first understand the concept of foot-candles, which is a measure of the illuminance or the amount of light that falls on a surface. It is defined as the illumination on a one square foot area of which the total flux of one lumen is uniformly distributed. The number of foot-candles required depends on the type of activity that will take place in the room. For instance, a living room might require less foot-candles compared to a dining room or a workspace.
Let's take the example you provided. If you have a living room that is 100 square feet and it requires 10-20 foot-candles, you would calculate the lumens needed as follows:
For 10 foot-candles: \( \text{Lumens} = 100 \text{ sq ft} \times 10 \text{ fc} = 1,000 \text{ lumens} \)
For 20 foot-candles: \( \text{Lumens} = 100 \text{ sq ft} \times 20 \text{ fc} = 2,000 \text{ lumens} \)
Similarly, for a dining room of the same size but requiring more light, say 30-40 foot-candles:
For 30 foot-candles: \( \text{Lumens} = 100 \text{ sq ft} \times 30 \text{ fc} = 3,000 \text{ lumens} \)
For 40 foot-candles: \( \text{Lumens} = 100 \text{ sq ft} \times 40 \text{ fc} = 4,000 \text{ lumens} \)
It's important to note that these are general guidelines and the actual requirements may vary based on factors such as the room's color scheme, the presence of windows, and the type of tasks being performed. For instance, a room with lighter colors will reflect more light and thus may require fewer lumens, whereas a darker room or one with less natural light might need more.
Additionally, the type of light source also plays a role. LED lights are more efficient and can provide more lumens per watt compared to incandescent or halogen bulbs. When choosing lighting, it's also crucial to consider the color temperature and the distribution of light to ensure even illumination across the space.
In conclusion, determining the number of lumens per square foot needed involves understanding the foot-candle requirements for the space, the size of the area, and considering the efficiency of the light source and the room's characteristics. With these factors in mind, you can calculate the appropriate amount of lumens to achieve the desired lighting effect.

To determine the needed lumens, you will need to multiply your room square footage by your room foot-candle requirement. For example, a 100 square foot living room, which needs 10-20 foot-candles, will need 1,000-2,000 lumens. A 100 square foot dining room, which needs 30-40 foot-candles, will need 3,000-4,000 lumens.
