LED Lighting

A light emitting diode is a source of light created by passing an electrical current through a diode, which is a two-terminal device commonly used in radios. As the 0th century elapsed, LED lighting has become more common due to its energy efficiency and low relative heat gain.

LED lights have been years used for traffic signals, police car lighting, exit signs and other non-essential lighting. For example, in commercial office buildings, almost all exit signs have led light sources so from a design perspective, their 5.4 watt load is negligible considering that 1400 watts can be loaded on to one circuit. Imagine if there was an entire office that had a load on each fixture of 5.4 watts?

The disadvantage to using LED lighting is the higher relative upfront cost. An LED 2’x4’ lighting fixture is almost three times more expensive than the fluorescent version of the same product. This is due to the fact that LED’s are not currently massed produced so the upfront investment, on paper, appears to be very expensive.

In reality though, a developer/investor will almost always get there return on investment over time due to the lower energy consumption, longer lamp life, smaller size and faster switching capabilities.

LED lighting currently has no comparisons when it comes to energy efficiency / lower energy bills. The upfront investment will right itself in the years to come which means that the occurrence of LED lighting will become greater and more economical.

Below are samples of the most commonly used LED lamps/bulbs:
