LED lights have been proven to be the better choice when compared to the alternative of incandescent and CFL lights. Not only are they long lasting, but they offer more advantages that make them the greenest light source around. The color temperature dictates the illuminating power and we at Burley Electric Services would like to share a guide to the LED lighting Kelvin temperature that determines LED lighting hue.
Light Emitting Diode Definition
Before we get into the Kelvin temperature, let’s cover the fundamentals of LED bulbs. LED is an acronym for ‘light emitting diodes.’ They use 75% less energy than traditional incandescent bulbs and last 25 times longer and with the rise in popularity, they cost is getting reduced, making them a more cost effective light source. As they are nearly the cost of incandescent and CFL bulbs, the technology of LEDs actually stems from a 100 year old scientific oddity that a multitude of scientists and engineers have morphed into multi-million-dollar product line.
When Was the Infrared LED Discovered?
Infrared LEDs were originally called ‘semiconductor radiant diodes,’ and made from a compound called gallium arsenide. Resulting in electroluminescence, or light emission, is when electric current was passed through this semiconductor material. Scientists and researchers were able to create LEDs bearing red and yellow hues, as well as LEDs that were bigger and brighter by adding other elements to semiconductor materials later in development. Recent advancements in LED technology have made them available in a wide array of hues, though they were originally only capable of emitting a single color or frequency of light. Included in the lighting spectrum is a broader spectrum of white light similar to sunlight and that of inefficient incandescent lighting.
LED Bulb Technology
Now an LED bulb comparable to a 60-watt incandescent can create the same amount of light using just 10-watts while producing minimal heat, another benefit. LEDs have an impressive lifespan though they don’t last forever. In studies, bulbs last more than 3 years if left running 24/7 with no heated filament of unusual gases. LEDs are flexible and can be applied in an array of environments from freezers to the front porch, giving home and business owners an incentive to make the switch to LED lighting. Over the next two decades, LEDs are hoped to reduce energy consumption for lighting by 50%, which will provide a mind-blowing $250 billion in energy savings. These lights are currently only contributing to 10% of the energy bill currently. Providing the nation makes the switch LED-use is expected to reduce carbon emissions 1,800 tons in the next 20 years.
LED Light Color Temperature Chart
Guide for LED Kelvin temperature determines LED lighting hue:
Less than 2,000 – Similar to a candle, the dim glow of bulbs less than 2,000K is best for ambient applications.
2,000-3,000K – Optimally used for living, dining, bedrooms, and outdoor living areas, the soft white, slightly yellow-hued glow of this temperature is ideal for day-to-day lighting.
3,100-4,500K – Surrounding vanities, offices work space, and the kitchen this bright white light can help you see doing tasks.
4,600-6,500K – Often used for display areas and workspaces that rely on bright illumination, the bright blue-white light of this range mimics daylight.
6,500K+ – Better used in commercial environments with the bright blue hues.
Variable – To quickly tailor their lighting via compatible mobile device, or Alexa/Siri/Google home homeowners have dimmable, color-changing smart bulb options.
