Lighting is a most important part to complete a home, office, shops even any place. Because for better visibility you need better light. Currently I noticed in most of the offices and clinics people use recessed lights/ pot lights. Most of the peoples visit those places and the lighting and the lighting style admire them. They think about installing the same lights at their places but sometimes they ignore some important point.
For recessed lighting 2 things are really important to get the proper lighting. The first thing is the number of required lights to brighten the complete room wall to wall and the space between lights. If you search on the web “How many pot lights do I need”, you will get many results but most of them are really complicated to understand, and for the other question you need to go to the web search again and type the question for answer.
But here I’m going to tell you some direct calculation without wasting your time, just put your values in the formula and get the answer of your question. Well the first question is the key to start your blue print for installation. So we will start with the question how many pot lights do I need or how many recessed lights are required to illuminate my room.
Well the first thing to know the exact number, how big is your room. Can you measure the length and width? Take the measurement and come back, also take idea is your ceiling high or normal, you can also measure to check that. Now let me tell you the formula with explanation.
Now you have the measurement in your hand. Multiply Length x width (Make sure the complete measurement should be in feet). Let say the length is 12 feet and the width is 20 feet.
So,
12 x 20 = 240.
Now tell me is your ceiling high? If not multiply your answer with 1.5, but if your ceiling is high so use 3 instead of 1.5. Now suppose you have normal ceiling.
240 x 1.5 = 360.
Well the answer will let you know how much wattage are required to illuminate your room properly. So you can say 360 total watts are required to brighten the complete room. Now our basic question “how many lights do I need” is still un-answered but I think you understand the calculation so in next step you’ll get your answer.
I’ll suggest starting placing the lights from center point of the room with the space. You know how many total wattages are required to lighten your room, now decide the wattage of single light. If you are going to buy a light bulb of 30 Watts, Now the below formula will apply.
Total Wattage / single bulb wattage = number of bulb.
So,
360 / 30 = 12.
So you got the answer. You need 12 recessed lights to lighten a 12′ x 20′ room. Now you need to decide how many rows you want to create. Let suppose you are going to have 3 rows so check the formula and put the value.
Length of the room / number of rows = Distance between 2 lights.
12 / 3 = 4 feet.
The distance between 2 lights should be 4 feet. But still there is 1 thing missing, what should be the distance of light and wall for starting point. It’s really simple divide the result with 2, yes the distance should be the half of the distance between 2 lights.
4/2 = 2 feet.
The distance of first light from wall should be 2 feet. Now you have all things in hand create the blue print and install the recessed lights and beautify the room with decent light.
