LED lighting solutions are on the rise and taking over the entire lighting market. You might even encounter new challenges maintaining or installing traditional incandescent and compact fluorescent (CFL) lighting. Now is the time to equip yourself with the knowledge to navigate the future of lighting.
LEDs are a different technology from what we have been used to for decades and you will want to be prepared to make the right LED lighting choices. Let this be your guide to a brighter world.
Why make the change to LED?
Besides being much more energy efficient than incandescent and CFL options, thus able to provide significant energy savings, they last much longer, don’t contain Mercury like CFLs, and provide way more options for brightness and light appearance (warm vs. cool).
In addition, LEDs don’t only come in a traditional light bulb shape. Due to their compact shape, LED lighting solutions come in all forms, shapes, and sizes, providing an almost unlimited amount of ways light can be used in a home environment, like sconces, molding illumination, or architectural accents.
When using LEDs, it is important to understand these three specifications that define lighting:
First off, we have to let go of the misconception that wattage equals brightness. While for incandescent bulbs wattage and brightness had a direct correlation, Lumens (lm) is the unit of measure for light output.
The color appearance or correlated color temperature (CCT) of light is measured in kelvin (K). When we want to know if a lighting fixture or bulb creates a warmer or crisper, cooler light we need to look for the kelvin number. The lower the number, the warmer the light will be and the higher the number the more cool and blue the light will appear. A typical incandescent bulb has a color temperature between 2700K and 3000K. The sun at noon on a clear day produces a light of approximately 5500K.
Light sources differ in their ability to render the colors of objects “correctly”. And by correctly, we mean compared to a natural light source like the sun or an incandescent bulb.
The color rendering is expressed as the Color Rendering Index or CRI. The scale goes from 0 to 100. A 2700K incandescent light bulb has a CRI of 100. A value of above 80 is considered a good CRI and will be sufficient for most applications.

The beauty of LED lighting is the wide range of colors that are available, the ability to change colors, and the complete control over the brightness of the light. If a surface shines when lit properly, an item glimmers in a way that catches the eye, or a unique texture can be highlighted. So simply cast the right light in the right area and you’ll be amazed how much more you’ll enjoy your home. Visit ElementalLED.com for more information or DiodeLED.com for product specs.
