Lighting is one of the most integral, functional and decorative part of Home. Lighting concepts play a key role in the design of living spaces. Light fixtures add style and personality to home. Lighting done correctly and tastefully can elevate the look and functionality of the space manifold. The choice of lighting significantly dictates the mood and ambiance of the room.
Lights in a room no longer consist of a single tube light. There are specific lights for creating the desired ambiance, highlighting pictures, murals or pieces of art, and reading.
LED rules Lighting Industry:
There have been a gradual but substantial change in the technology employed by the lighting industry. In the past decade, there has been a gradual transition from the use of incandescent bulbs to halogen lamps to fluorescent lamps to LED lamps.
LEDs lights started out their applications mainly as downlighters and panels. Now, they are increasingly preferred for creating innovative lighting schemes, thanks to significant advantages of longevity, low power consumption, low maintenance costs and being environmentally friendly. The lighting industry employs LEDs in wide variety of designs right from wall lights to chandeliers, picture lights, tube lights, pendants, table lamps and bulbs.
The color output of the light is very important for well-designed lighting. The color temperature is measured in Kelvins (K). In general, the color tone range from 2700 K (yellow light/ warm white) to 6500 K (cool white light) is used in lighting industry.
In home lighting, 2700 K is generally preferred in the living and bedrooms. In task areas like kitchen, bathrooms and study areas,6000-6500 K color temperature is preferred. In offices, 4000, 6000-6500 K is recommended. For highlighting products in commercial establishments, 2700 K is preferred.
In the Jewelery industry, 2700-3000 K is preferred for highlighting gold jewelery and 6000-6500 K is preferred for highlighting diamond jewelery.
The lux level is a measure of the intensity of light on a surface. Maintaining appropriate lux levels is fundamental in lighting design.
Lux considers the area over which the luminous flux is spread. A flux of 1000 lumens, concentrated into an area of one square metre, lights up that square metre with an illuminance of 1000 lux.
One lux is equal to one lumen per square meter. It is light intensity in a specific area.
In living rooms, kitchens, dining areas, and meeting rooms, a level of 300 lux is recommended. In bedrooms, spas, wellness centres, and restrooms, a level of 200 lux is recommended.
The light has two functions:
It should create a flattering ambience, and
There should be appropriate task lighting.
How much light do I need in a room?
Multiply width of room x length of room x 1.5 = amount of total minimum wattage needed (for 9-10 feet ceiling height). Divide by 10 to get the equivalent LED wattage. For example, if the room size is 15*20 feet, then multiply 15*20*1.5=450. Divide this value by 10. So, you need 450/10=45 watt of LED light in the room. The calculation is based on the LED quality that gives out around 90-100 lumens per watt. Considering a 9-watt LED bulb, you will require at least 5 number of 9-watt LED bulbs to illuminate the room.
An LED bulb can give you as many as 100 lumens per watt as compared to an incandescent bulb that will produce only 12-17 lumens per watt.
Break your room into layers of lighting.
Keep bulb lighting colours same.
Control each light layer separately.
There can be three layers of lighting in a room:
Ambient or general Lighting provides light throughout the Room. This would be overhead lights like chandeliers and ceiling fixtures.
Task lighting adds extra light to areas where chores and activities get done, like reading a book in bed, chopping/cooking in Kitchen, applying makeup, etc.
Accent or Decorative Lighting adds interest to the décor or architecture like cove lights, cabinet lights, picture lights.
The centre point in the Living Room is the focal point, both aesthetically and functionally.
Light one or two corners, focussing the light on an object like an art, plant, sculpture, etc.
Create spaces for smaller table lamps. A corner floor lamp can be a nice addition.
How do I choose the size of chandelier?
A simple thumb rule can help you decide the size of chandelier.
Add the length and width of the Room. For example, if your room size is 15ft* 20 ft, then add 15+20=35.
The recommended width of your chandelier is 35 inches.
What should be the height of chandelier?
This depends on your ceiling height. Bottom of the chandelier should be at least 7 feet from the floor. If your ceiling height is low, then use flush mount fixtures, or use close to ceiling hanging fixtures. In case the height is more, use a chandelier with 2-3 layers.
Multi-unit hanging chandelier for high ceilings, in a spiral or random setting is a great idea.
If there is a window in that area, position the chandelier such that it can be seen from outside.
Use a chandelier or pendant above the table. With a long rectangular table, go for a linear light with multiple pendants.
You can experiment if all pendants can be at same height, or at varying heights creating concave or convex setting.
It is recommended that the bottom of the light should not be lower than 30 inches above the table top.
The Kitchen light should be bright, task light.
Use fixed to ceiling or pendant lights.
Use cabinet lights for the cabinets.
Brighten the counter space with sleek, long under counter lights.
Make a cozy ambience in the Bedroom. Pendants on both sides of sides of the bed create a pleasing look.
For reading, use Bedside lamps or focused reading lights on the bedside.
For the table lamps, it is desirable that the bottom of the shade is a little below your line of sight, about 16-18 inches from the top of the mattress.
A table lamp of size 25-28 inches should work well. Aim for a soft dresser light.
Ten tips in Light design:
1. Light in layers.
2. Wow your powder room.
3. Have fun with pendants.
Whether pendants are used over breakfast counter, or over a reading nook, pendants provide a great source of illumination and style. Their compact size and adjustable height allow you to use multiples and arrange those in creative ways. You could choose pendant lights from different collections, stagger them or create a cluster.
