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.
Here’s all you need to know to brush up your knowledge:
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 & Lumens aren’t the same.
Yup, you’ve read that right! It is the most common mistake we all make. Wattage is the amount of energy a light source uses. While Lumen is the measure of the total amount of visible light to the human eye from the light source i.e a bulb or a batten.
So, every time you go out to buy yourself a bulb, you should ideally check for Lumens.
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 -
Bedroom | 100 lux |
Reading Room | 300 lux |
Kitchen | 250 lux |
Hall/ Living/Dining | 150-200 lux |
Bathroom | 100 lux |
Balcony | 100 lux |
Store Room | 100 lux |
Stairs | 100 lux |
Parking | 50 lux |
Driveway | 100 lux |
Calculation Example:
Bed room dim: 10’x10’ =>area= 100 sq. ft = 10 sq. meter. (approx.)
Required illumination : 100 lux (lumen/sq. m)
Total lumen required= required illumination X area of the room = 100lumen/sq. mX10 sq. m = 1000 lumen
If we are using 9W Wipro Garnet Round Panel light fixture emitting 630 lumen each , then no. of fixtures required be approximately
= 1000/630 ~ 2
Note: This is an indicative figure. Actual no. fixtures to be installed must be at least 30% higher than the obtained result to incorporate light losses in the ambient.
4. Which Light to apply where?
There are 3 types of Light Layers and each have a different application purpose:
- Ambient or General Lighting – An even application of light throughout the space. Eg: Wipro Downlights
- Task Lighting – Light needed to adequately perform a task. Cabinet lights or kitchen platform lights.
- Accent or Decorative Lighting – Light that adds interest to the décor or architecture. Eg: Wipro Spotlights or Wipro LED Downstrip Lighting.
Now that you know the basics to Perfect Lighting, it will be easier for you to select the right light for the right room.
