LED lights are 50% less to operate than flourescent bulbs.

How is LED lighting different than other light sources, such as incandescent and CFL?

LED lighting differs from incandescent and compact fluorescent lighting in several ways. When designed well, LED lighting can be more efficient, durable, versatile and longer lasting.  LED lighting products use light emitting diodes to produce light very efficiently. An electrical current passes through semiconductor material, which illuminates the tiny light sources we call LEDs. The heat produced is absorbed into a heat sink.


Common LED colors include amber, red, green, and blue (white is created by mixing and converting colored lights).

LED products can last 25 times longer than an incandescent bulb and use 75% less energy.

LEDs and Heat

Because LED lighting systems don’t radiate heat the way an incandescent or halogen light bulb does, the heat produced from the power going into the product must be drawn away from the LEDs. This is usually done with a heat sink, which is a passive device that absorbs the heat produced and dissipates it into the surrounding environment. This keeps LEDs from overheating and burning out.

LED products use a variety of unique heat sink designs and configurations to manage heat, so they may look very different from each other. Regardless of the heat sink design, all LED products that have earned the ENERGY STAR have been tested to ensure that they properly manage the heat so that the light output is properly maintained through the end of its rated life.


What are LEDs?

LEDs, or light–emitting diodes, are semiconductor devices that produce visible light when an electrical current passed through them. LEDs are a type of Solid State Lighting (SSL), as are organic light–emitting diodes (OLEDs) and light–emitting polymers (LEPs).

The Work Environment


Many employees complain about working under fluorescent bulbs, which are the standard in most companies due to energy savings.  However, more studies are finding that fluorescent bulbs can induce stress, anxiety and migraines.   Of all produced light sources, LED lights come close to mimicking the sun, producing healthier, more productive work environments, while saving you 50% or more on your energy costs associated to lighting.


 

Environmental Impact of Fluorescent


Environmentalists hailed fluorescent bulbs as a key component to reducing our energy footprint and helping the environment. However, because mercury is an essential element in fluorescent lamps throughout the world, and as those lamps are thrown into landfill, the mercury can escape and contribute to air and water pollution (e.g., it can easily leach into groundwater supplies).
