Why LED Lights Use Less Electricity

A hand replacing an LED light bulb

Ever wonder how an LED light fixture conserves so much energy? To answer this question, we need to dissect its five critical components. 

The light-emitting diode (LED) is one of the most energy-efficient and rapidly-developing lighting technologies in the market today. Quality LED light bulbs last longer, are more durable, and offer better light quality than other types of lighting. But what gives this technology such an advantage? 

In this blog, we break down everything you need to know about LED lighting efficiency. Our experts define some of the main reasons these Energy Star solutions stand out as a superior light source.   

The Science Behind LED Light Efficiency 

Heat Reduction

LED bulbs are designed with heat dissipation features. Some applications include heat sinks, which prevent the bulb from overheating. Unlike traditional bulbs, LEDs reflect the light’s heat instead of absorbing it. This prevents lights from getting too hot to the touch.

Environmentally-Friendly Material

LEDs don’t share the same environmental issues as other traditional lighting sources. Unlike fluorescent or incandescent vapor lights, LEDs don’t contain chemicals that are harmful to the environment. Many conventional light sources are made of mercury, a substance that leaches into landfills and pollutes groundwater. Mercury waste is a leading cause of wildfires and organ damage. Aside from its toxic implications, mercury is an internal component of the bulb and requires special handling at the end of the product’s useful lifespan.

Stronger, Organic Light Sourcing

LEDs are engineered to mimic the effects of natural light. Unlike traditional glass or plastic bulbs, LEDs are built with semiconductor matter, an element that emits light at a brighter level. Since layers of contracting material don’t constrain these bulbs, they can produce more illumination without having to work twice as hard. 

The main semiconductor compounds manufactured into LEDs include:

  • Indium gallium nitride (InGaN): blue, green and ultraviolet high-brightness LEDs
  • Aluminum gallium indium phosphide (AlGaInP): yellow, orange and red high-brightness LEDs
  • Aluminum gallium arsenide (AlGaAs): red and infrared LEDs
  • Gallium phosphide (GaP): yellow and green LEDs

Better Light Direction

While other light technology emits a full 360 degrees around the source, LED systems target a 180-degree release. This complete emission causes accessory devices to reflect and/or redirect the light. Since LEDs emit light in a specific direction, it reduces the need for reflectors and diffusers that trap light. This feature makes LEDs more efficient for many uses, such as recessed downlights and task lighting. With other conventional light sources, the bulb must be reflected to the desired direction, and more than half the light may never leave the fixture.

Flexible Light Designs

LEDs are adaptable lighting technology and their bulbs are designed to support virtually any application. Since the bulbs are much smaller than incandescent technology, they don’t take up much room in your light fixture. Users can combine bulbs in bunches to make up the space of a traditional bulb or in isolation as a small device light. You can even string them out in a linear sequence, and they won’t exert even half the energy as a traditional light source.

Low Voltage Power

In many cases, LEDs operate on very low voltages. This makes them suitable for outdoor applications where another lighting might not meet code, such as an oceanfront home where the ground level of the property is in a flood zone.
