4 Light Sources in Interior Design

Light is the important element in the design of any modern home. In this article, we will provide more information about 4 light sources that are commonly used.

The goals of lighting in interior design are to make lighting suitable for the purpose of the design, to make the areas look nicer and to make the best choice based on budget. There are 4 types of artificial light sources that we would like to talk about as below,

1. Fluorescent Light
Fluorescent light is one of the most common light sources anywhere in the world. It is shadowless which is ideal for general purpose usage. In the past, it was used as a ceiling lighting. Now it is used more in bathroom lighting.

Fluorescent Light
Compact Fluorescent Lamp (CFL) is smaller, consumes less energy and last longer. However, it's way more expensive than a standard fluorescent lamp. Moreover, it can't be used with a dimmer switch and electronic timer due to fire hazard. Also, it shouldn't be used outdoors and as an emergency light.

Colored Fluorescent Lighting is also known as "Neon". It is often used as exterior signs. However, some interior designers try to use it more in interior design.

2. Incandescent Light 
Incandescent light produces a warm color spectrum. It emits a lot of heat, has a shorter service life but it's inexpensive.

Incandescent Light
In contrary to fluorescent lighting, it can be used safely with dimmer. Some of the most common applications of incandescent light are for the ceiling, table lamps, and Christmas lighting.

3. Tungsten Halogen Light
Tungsten Halogen Light or Halogen Light, in short, is another type of incandescent light. The difference is that halogen light is filled with halogen gas and it looks closer to natural sunlight.

Halogen Lighting
The good point of halogen light is that you can direct the light to specific areas. Halogen light is much more expensive than that of a standard incandescent light. However, its service life is a lot longer and it's typically brighter. The most common application of halogen light is a spotlight.

4. LED Light
LED stands for Light-Emitting Diode (LED). It's a microchip that produces light by converting electricity. So, the size of the LED is smaller but it produces light with higher intensity.

LED Lighting
LED emits minimal heat and contains no mercury. The service life of LED is about 50,000 hours. It can be used with a dimmer and the color doesn't change. Also, it doesn't cause interference wave because it doesn't use a ballast.

LED light is ideal to use in art lighting, in hallways, under counters, in staircases and can be used outdoors.
