Understanding the Different Types of Light Sources


Buying a light bulb or lamp is not that simple anymore. With the advancement in technology and increase in environmental awareness, energy conservation has become a paramount concern. It is common knowledge that buying the right bulb or lamp can reduce your energy bills and positively impact the environment. But with the different types of lighting technologies available, which one should you choose?

In this post, we’ll explore the types of light sources to help you choose the best one.
Here are the main light sources used in homes:

1. Incandescent Bulbs

Incandescent bulbs are the oldest and most commonly used light bulbs. They produce light when a wire called a tungsten is heated by electric current passing through it making it very hot that it starts to glow. This makes the bulbs to release a lot of heat and get hot to touch. Consequently, they are inefficient and don’t last very long compared to other sources of visible light.

Although inefficient, incandescent lamps have numerous advantages – they are inexpensive, are available in a wide range of shapes and sizes and give off a warm light with excellent colour rendition.

2. Fluorescent Light Bulbs

These light bulbs are far more efficient than incandescent bulbs. They use a quarter of the energy used by incandescent products to produce a similar amount of light and last 6-5 times longer (6,000-15,000 hours).

Fluorescent light bulbs are filled with mercury vapour that produces UV rays when electricity is applied. There is also a coating on the inside of the bulb which turns the UV rays into visible light. The way fluorescent bulbs work allows them to generate a lot of light but not much heat, making them an energy-efficient option.

Fluorescent lamps are available in a variety of shapes and styles, and each is designed for a specific purpose. The total surface area (size) of the bulb determines the amount of light it produces.

Some of the most common types of fluorescent bulbs include compact fluorescent lamps (CFL), reflector bulbs, floodlight lamps and tube fluorescent lamps.

3. Halogen Bulbs

Halogen bulbs work in a similar way to incandescent bulbs. Unlike the incandescent lamps, they have halogen gas that re-deposits the burnt off tungsten onto the filament for reuse.

These bulbs are more energy efficient, last longer and burn at a higher temperature than the standard incandescent lamps. Halogen lamps are commonly used in recessed lights, pendant lights, and under-cabinet lighting.

4. Light Emitting Diode (LED)

The LED is one of the most energy-efficient and rapidly evolving technologies. LED lamps, especially ENERGY STAR certified lamps, use about 75% less energy and have a longer lifetime (40,000 hours) than incandescent lighting.

LED lamps are very different from other lighting sources such as fluorescent bulbs and incandescent bulbs. Key differences include:

• Light source – LED lights emit light through the rapid movement of electrons in a semiconductor device.
• The direction of light – LED lighting emit light in a specific direction, eliminating the need for diffusers and reflectors that can trap light. This makes LEDs ideal for a variety of uses including task lighting and recessed downlights.
• Heat – LEDs produce very little heat when compared to other light sources.

Generally, Light Emitting Diodes (LEDs) are the most energy-efficient lighting technology you can buy for your home. Additionally, they have a long lifetime, are compact and can be used in a variety of applications.
