LED Lighting is no longer a futuristic technology. Today, LED Lights are available in a wide variety of shapes and sizes. But, why choose LED Lighting over any conventional lighting? Not Sure? Well, let’s take a look at some of the benefits of using LED Lighting both in residential or commercial.
Hopefully, this gives you a better idea about Why to choose LEDs over any conventional bulbs.
A light-emitting diode, also known as LED, is a semiconductor light source. Currently the LED lamp is popular due its efficiency and brightness. Many believe that LED is a “new technology”; however, the LED as we know it has been around for over 50 years. The recent development of white LEDs is what has brought it into the public eyes as a replacement for other white light sources.

Ambient Lighting: Lighting designed to provide uniform light levels throughout an area.
Ampere (Amp) –The unit for measuring rate of flow of electrical current calculated by the following formula: Current (Amps) = Power (Watts) / Voltage (Volts)
Backlighting – Use of light source to illuminate from behind without protrusion through the panel.
Ballast – The device that limits amount of current in an electrical circuit.
Beam Angle – Size of the cone of light produced by lighting source measured in degrees.
Brightness – Often used incorrectly with respect to illumination as a synonym for luminous flux, an objective measurement of the visible power of a light source. The term is correctly used when describing screen brightness in a display or television.

Carbon Dioxide (CO2) – A colorless, odorless gas that naturally exists in the earth’s atmosphere. The major source of manmade CO2 emissions is from the combustion of fossil fuels. Carbon dioxide is the primary greenhouse gas and is known to contribute to global warming and climate change.
Color Definition – The color of uniformly illuminated objects described using three terms:
Hue: Describes the situation when the appearance of different colors is similar (e.g. matching blues and pinks).
Lightness: Describes a range of grayness between black and white.
Chroma: Describes the degree of departure from gray of the same lightness and increasing color (e.g. red, redder, pure red).
Color Temperature – The description used to describe the effect of heating an object until it glows incandescently, the emitted radiation, and apparent color, changes proportional to the temperature; easily envisioned when considering hot metal in a forge that glows red, then orange, and then white as the temperature increases.
Cool White – A description of light with a correlated color temperature between 5000K and 7500K, usually perceived a slightly blue.
Controller – A device that controls the output of color-changing and tunable white lighting fixtures. Controllers typically have software components for configuring fixtures and designing and editing light shows, and hardware components for sending control data to fixtures.
Correlated Color Temperature (CCT) – The phrase use to describe the temperature at which a Planckian Black Body Radiator and an illumination source’s appear to match, usually specified in Kelvin (K).
Daylighting – The use of natural light to supplement or replace artificial lighting. Strategies include the proper orientation and placement of windows, use of light wells, light shafts or tubes, skylights, clerestory windows, light shelves, reflective surfaces, and shading, as well as the use of interior glazing to allow light into adjacent spaces.
Die – The chip or heart of the LED
Diffuser – An object with irregularities on a surface causing scattered reflections.
Direct Current (DC) – Electrical current which the flow of electric charge moves in one direction only.
Down Light – Light source set in a metal cylinder. Mounted or recessed into the ceiling so the beam of light is directed downward.

E26/E27 – Edison Screw fitting system designated at standard screw-in bulb bases. Also referred to a “Medium” or “Standard” Base.
Eco-friendly – Having little or no impact on the native ecosystem.
Efficacy – The light output of a light source divided by the total electrical power input to that source, expressed in lumens per watt (lm/W).
Energy Efficiency – Ratio of energy output of a conversion process or of a system to its energy input.

High Efficiency – General term for technologies and processes that require less energy, water, or other inputs to operate. A goal in sustainable building is to achieve high efficiency in resource use when compared to conventional practice. Setting specific targets in efficiency for systems (e.g., using only EPA Energy Star certified equipment, furnaces with an AFUE rating above 90%, etc.) and designs (e.g., watts per square foot targets for lighting) help put this general goal of efficiency into practice.
High Power LED – A high power LED, sometimes referred to as a power LED, is one that is driven at a current of 350 mA or higher.
High-brightness – High-brightness is a term that is often applied to an LED but has no measured meaning and does not indicate any level of performance.
Illuminance – The intensity of light falling on a surface area. If the area is measured in square feet, the unit of illuminance is footcandles (fc). If measured in square meters, the unit of illuminance is lux (lx).
InGaN LED – The preferred LED (Light Emitting Diode) semiconductor material system containing Indium, Gallium, and Nitrogen to produce green, blue and white-colored LED light sources.

Leading Edge Dimmer – A type of dimmer that regulates power to lamps by delaying the leading edge of each half-cycle of AC power. Compatible with many LED fixtures.
LED – A Light Emitting Diode (LED) is a solid-state semiconductor device which converts electrical energy directly into light. On its most basic level, the semiconductor is comprised of two regions. The p-region contains positive electrical charges while the n-region contains negative electrical charges. When voltage is applied and current begins to flow, the electrons move across the n region into the p region. The process of an electron moving through the p-n junction releases energy. The dispersion of this energy produces photons with visible wavelengths.1
LED Chip (Chip) – The light producing semiconductor device that may or may not be incorporated into an LED.
