Incandescent Light

Incandescent light is one of the oldest form of lighting source that were introduced more than 125 years ago by Thomas Edison. They work by heating metal filaments until they are extremely hot enough to create light. Incandescent light is the most inefficient source of lighting out of any other lighting technologies, as almost all energy is wasted in the form of heat while only a little energy is converted to produce light, and they have a very low life span.

Fluorescent Light

Fluorescent lights have been around for nearly 30 years. Fluorescent light produce light by heating up a gas, phosphor, and mostly mercury, which can be harmful to both human and the environment. Although fluorescent lights are energy efficient and often less expensive than incandescent and halogen lights, they have quite a few disadvantages. They exhibit flicker effect and are unable to turn on instantly with full brightness; and they usually produce a constant annoying buzzing/humming noises. Furthermore, fluorescent lights emit high UV and infrared radiation and also create heat leading to high temperature, thus they are also made with glass. Furthermore, once the glass cracks or breaks it releases mercury vapour and other gasses that can cause contamination and can damage the nervous system, brain, liver and kidneys. Hence fluorescent lights are required to be disposed of responsibly.

Halogen Light

Halogen lights emit lights by passing electricity through its tungsten filament that is enclosed in a small bulb containing halogen gas. In a way, halogen is superior to incandescent lighting as it generally lasts longer and offers a brighter and more vibrant light. The down side of halogen lighting is they operate at an even higher lamp temperature, hence radiate a huge amount of infrared heat, making them a fire hazard as well as an inefficient light source.

Light Emitting Diodes (LEDs)

LEDs are solid-state semiconductor device, which means they do not require heating of metal filaments or the use of chemical elements to light up. LEDs create light when their semiconductor crystal is stimulated by electricity. Recent advancement of LED technology has led the LEDs to become desirable for residential and commercial lighting applications. Their extensive benefits include superior energy efficiency while generating very little heat, high luminous efficacy, instant light, low maintenance, highly durable, long life span and low environmental impact. These vital benefits have definitely make the LEDs to become the best alternative to conventional light sources, and provide a wider range of applications.
