What are LEDs and How Do they Save?

LED stands for Light Emitting Diode - the newest, most energy-efficient form of lighting. Unlike standard incandescent bulbs that use a large amount of energy to power (much of which is wasted as heat), LED bulbs require very little, converting 95% of their energy use into light.

Less energy use reduces the demand from power plants, decreases greenhouse gas emissions, and saves you money. Click to learn how much our ENERGY STAR certified LEDs will help you save.






How to Choose the Right LEDs: 3 Considerations

Due to new technology and great variety, shopping for LEDs online is different than shopping for standard bulbs in-store. How do you know which LED is right for you? Just like with standard bulbs, the same considerations apply - will it fit, will it be bright enough, and what will it look like when illuminated?


Bulb Styles and Bases - A Quick Rundown


Bulb Styles
The styles of light bulbs fall into a handful of broad categories, each of which has a letter value. For example, general use light bulbs are in the "A" category. Following each of these letters is a numeric value, representing the width of the light bulb in eighths of an inch. Therefore, an A19 is a general use light bulb that is 19 eighths of an inch wide. The higher the numeric value, the larger the diameter of the light bulb.

Bulb Bases
The base of a bulb refers to its connection to the lamp or fixture it fits inside of. The most common base is an E26 medium screw base. Click to learn about other common bulb styles and bases.



Lumens, a Measure of Brightness

It is a common misconception that watts = brightness, but it is in fact lumens that measure brightness. The higher the lumens value, the brighter the light. Here's some history.

In 2007 the Energy Independence and Security Act (EISA) included provisions to improve the efficiency of general use light bulbs by at least 25%. Pre-EISA, a 1,600 lumen general use incandescent lamp would typically consume 100 watts of electricity, but post-EISA a general use lamp could consume no more of 72 watts of electricity.

Kelvin, a Measure of Color

The correlated color temperature (CCT) is the color of a bulb, measured in degrees Kelvin. The lower the value, the "warmer" (more yellow) the color of the light. The higher the value, the "cooler" (more blue) the light. The most common color temperature is 2,700 degrees Kelvin (soft white).
