Accent Lighting

You can use this lighting when you have to focus on a single area or an object. These lights are three times as bright as compared to ambient lighting. If you are looking to place a small object under bright and clear light, then accent lighting is a must in your room. 

What is the Formula to Calculate the Lighting for the Room or Area?

You need to consider the dimensions of the room before calculating the amount of light required. Here is the formula for calculating the needed light in your space.

Power Wattage to Brighten Up Your Room = Length of the Room x Width of the Room x 1.5

You can understand the above formula through a simple example. Suppose the length of your room is 16 feet, and the width is 12 feet. You need to multiply the length and width by 1.5. You will get 288 Watts. The light with this much power wattage is required in your room to light it adequately. You can install two lamps of 150 Watts. The light will be equally distributed to all the corners of the space. 

What are the Different ways to Illuminate the Space?

Generally, you can choose between two options to illuminate your rooms. One is to install more light sources, and the other one is to install brighter lamps. You may prefer to use more lights of less wattage instead of few ones with high wattage. The main reason to avoid more fluorescent bulbs is that it can harm or cause eye strain. 

You should not compromise your health to get a better lighting effect in your home. Before buying the lights for space, check the number of sockets on the fixture, and consider the lumen count. For instance, five sockets that are installed with bulbs of 800 lumens can produce 4000 lumens. If you find it not enough for your room, you must get a fixture with more sockets. 

How to Determine the Lumens of Lights Required in Your Space?

The brightness of the light is measured in lumens. It is calculated by considering the amount of emitting light from the source. There is a formula to get an estimation of lumens required in a space. You have to multiply the square footage of the room (length of the room x width of the room) by the number of foot-candles (Number of lumens required to cast the area of one square foot). 

How to Determine the Amount of Lighting in Different Places?

Your house consists of many rooms and spaces. It is essential to install lights in every corner to get adequate light in the dark. You have to consider all the areas from your house’s entry to your kitchen. You have to decorate every room with different types of lights.

For example, if the height and the foyer’s width are 12 and 18, then the sum is 30. The diameter of the hanging light should not exceed 30. You can quickly determine the power wattage with the formula mentioned above. If your entrance space is small, you should try small pendant lights, buffet lamps, wall sconces, etc. 

Lobby and Staircase
