Different Lighting Technologies Explained

LED Light Expert gets lots of questions about the different lighting technologies.  Understanding the old lighting technology will help you understand why LED Lights are so much better and which ones to choose. 

Here are most popular lighting technologies which can be used for commercial and residential applications include

Incandescent:

The glass use in this bulb contain a wire filament passes the electric current which heat up the filament and radiates the energy as visible light.  For the last 100 years incandescent bulbs are very popular and common type of bulb. It has the standard of color rendering and fulfil the expectations of customers.

·         High heat creation

·         Very inefficient light

 

Compact fluorescent:

Light is not produced through filament in CFLs, instead they use a glass tube for production of light. On glass tube phosphors is coated that contain a small amount of argon and mercury vapor and electrodes at one end. The electrodes generate invisible ultraviolet light when electricity is applied on it. This ultraviolet light excites the fluorescent coating on the inside of the tube to produce visible light.

Halogen:

In order to increase light output and efficiency of the incandescent bulb the halogen bulb uses halogen for this purpose. Halogen bulb provide a brighter, whiter light than is provided by the incandescent bulb. They produce a typically higher efficiency than incandescent bulb. Homeowners mostly use the halogen bulb because they are better suited for directional aiming of fixtures. They are often used on movie sets and also in auto headlights.

Metal halide:

It consists on the tube generates an intense bright white light. This tube contains the mixture of gas, mercury and halide salts.   Very common in fixtures over the last year including wall packs and other commercial fixtures

·         High intensity discharge technology

·         Very efficient

·         Have excellent lamp life

·         Putting out a tremendous amount of light

 

High Pressure Sodium;

There is a low pressure and high pressure version, but the high pressure is the one you see in commercial lighting.   The technology actually dates back to 1932.  It is recognizable by the orange yellow color classically seen in post and street lights.

·         Very good lumens to watt ratio

·         Available in high lumen output for large area

·         Poor quality light and produce a horrible CRI.  Usually about 20.

·         Sodium can be dangerous.

 

LED:

Light-emitting diodes, are a solid state and very popular technology which has no filament, glass envelop, gas, or mercury. When voltage difference is applied across a semiconductor material then electrons starts movement. This movement causes light through LEDs. Light of specific wavelength range is produced through each semiconductor material because LEDs are not able to produce white light on their own. LEDs are using in home because they use 90% less power than incandescent bulb. These light are

·         Ecological friendly

·         Ideal for large fixtures like LED Parking Lot Lights

·         Zero ultraviolet emissions or mercury

·         Very durable

Cost and efficiency

The following methods are involved in calculating the cost and efficiency

·         Lamp life

·         Lamp cost

·         Wattage per fixture

·         Usage

·         Energy costs
