WHY SWITCH TO LED LIGHTS?
Nov 19,2014


- Last 3 to 25 times longer than traditional lighting.

- Consumes 25% to 80% LESS energy than traditional light fixtures.
- Lowers carbon footprint by 50-70% and can achieve 80% when coupled with smart controls. (ie. Dimmability function, photosensors, motionsensors, intellient wireless control systems, etc.)
- After the initial 6,000 hours of use, LEDs have a 1% failure rate.
- Emits very minimal heat, therefore harnessing most of its energy towards illuminance.
- Emits directional light which minimizes wasted light and energy and provides a focus where light is needed.
- All materials are non-toxic, recyclable, and need not be specifically segregated.
- Do not contain fragile glass or filaments leading to durability to withstand shock. 
- Does not emit UV which can damage skin cells, art work, fabrics or other UV sensitive materials.
- Does not attract bugs.
- Can create full color spectrum lights, are very small and many can be continuously expanded allowing for greater scale. (Might just be displays..TBD)

LED Light Terms

LED

An acronym for Light Emitting Diode.

LED Lighting Fixture

An assembly of multiple LED lights to increase luminosity. Many LED fixtures are designed to retrofit existing lighting structures i.e. post lamps or fluorescent tube lighting.

Lumen

The measure of luminous flux or the quality of light. A lumen is equivalent to the amount of light that is spread over a square foot of surface by one candle power when all parts of the surface are exactly one foot from the light source.

Power Source

The power source of LED lighting (measured in volts).

Luminaire Rated Power

The measurement of the wattage required to power the light.

Power

Consumption

The amount of energy required to power the light (rated in Watts).

Color Temperature

Known as CCT is the a measurement to indicate the intensity of the light indicating the degree of a yellow or blue tint to white light (measured in Kelvin).

Color Rendering Index

The measure of a light's color characteristics and its ability to replicate real daylight, CRI is rated on a scale from 1-100.

Heat Sink

A thermal system design that dissipates heat away from sensitive light or electric components.

Frequency

The measurement of cycles of alternating current per second represented (by the unit Hertz or Hz).

Flux Output

The measurement of the total lumens produced by a light fixture.

Flux Efficiency / Luminous Efficiency

Flux efficiency is a ratio comparison between luminous output and power consumption expressed as lumens per watt (lm/W).

Rated Lifetime

The total amount of time it can operate at peak performance.

Energy Consumed

The common measurement to calculate energy consumed is kilowatt hours (kWh).

Amp

A calculation of wattage divided by voltage. Current (Amp) = Power (Watts) / Voltage (Volts).

Light Output

Light output is a measurement of the perceived power of light emitted by the human eye.

Efficacy

Efficacy is a measure of how efficient a light is in converting electrical energy to visible light (expressed in Lumens per watt).

Wattage

Wattage is a measure of electrical power expressed in watts.

Dimming Capability

Dimming capability, measured in bits, represent the various levels of brightness control.

Viewing Angle (Horizontal / Vertical)

Viewing angle is the maxi mum angle at which a display can be viewed with acceptable visual performance

Operating Temperature

The range in which the fixture will function.

IP Rating

IP rating is the degree of protection provided for the LED screen against the intrusion of both solid and liquid substances.

Wattage

A unit of electrical power. Lights are rated numerically by watts to represent the amount of energy required to power the unit.

Kilowatt

A measure of electricity equivalent to 1000 watts.

Kilowatt Hour (kWh)

The standard measure of electrical energy. For example, a 10 watt bulb operating for 100 hours would use 1 kWh of energy.
