Lighting 101: The Basics of Home Lighting

I want to buy lights for my drawing room, what is the ideal bulb wattage I should consider buying? Lumens. What are Lumens? The light I bought the other day only covers one part of my room. Why! Which light should I choose for which room? We’ve all encountered such doubts during the need of the hour, especially when our lights require replacement. 

Quite often, we downplay the importance of Good lighting and how it can easily make or break our homes interiors. But before we set out to brighten up our homes interiors, we believe it is important to understand and learn the key basics to Good Lighting.

1.Why Choose LED lights over conventional lights?

LEDs have proven to last for up to 50,000 hours in comparison to CFLs. and if that’s not enough, they are great when it comes to energy saving which is almost 50%. With no mercury in them, they are eco-friendly lighting solutions that do not emit harmful UV and IR radiations.

2. Watts and Lumens aren’t the same

3. How much light will I need?

Most often, before deciding how many lights do you require to light up a room, you need to measure the amount of light output needed in a given area. Lux is one such measurement that helps us do just that. It is most often used by interior designers and architects while creating a home layout. If you are wondering how you can measure the lux of your desired space, it can get quite tricky. So to help you sail through it, we have broken it down into parts to make it easier for you. 
One lux is equal to total lumen falling on a unit surface area (Sq.m)

As per Indian standards,  every household requires a certain amount of lux, which you can find in the table below - 

Calculation Example

Room dimensions

10 ft x 10ft => Room area = 100 sq.ft = 100 sq.ft = 100 sq.m (approx.)

Required illumination

100 lux (lumen/sq.m)

Total lumen required

Required Illumination x Area of the Room = 100 lux(lumen/sq.m) x 10sq.m = 1000 lumen

4. Which Light to apply where?

There are 3 types of Light Layers and each have a different application purpose:
