The End of a Lighting Era

incandescent will no longer be sold in CIn 2018 California said goodbye to the incandescent light bulb. Thomas Edison gave the first public demonstration of his incandescent light bulb in December 1879, we’ve continued to use this technology for almost 140 years. However, as more efficient light bulbs have emerged states are moving toward energy saving options.

Why the change?

Congress passed the Energy Bill of 2007 which was signed into law by George Bush. The law completely phases out the incandescent bulb by 2020 in the United States. California is the only state that phased out incandescent in 2018, two years early.

What happens to all the incandescent bulbs?

Retailers will sell all remaining inventory on the shelves. Incandescent bulbs will not be manufactured. Manufacturers had 11 years to expand their offering to more energy efficient lighting products.

How will this impact consumers?

There are 250 million incandescent light bulbs in use in California according to the Natural Resources Defense Council. When consumers replace the quarter of a million incandescents with LED light bulbs, consumers will save roughly $1 billion on electricity.

What will replace traditional light bulbs?

There are two alternatives are LED and CFL (compact fluorescent) bulbs. CFL lights contain Mercury which is a hazardous material and takes time to warm up to full brightness. LED light bulbs contain no mercury, turn on within a second and are shatter resistant. They are safe for your entire family and recyclable. You can learn more about comparing the different lighting options here.

Viribright’s full line of LED light bulbs will make the switch easy. Our light bulbs are UL listed, which have been tested to meet all the safety requirements. We offer a dimmable option on a lot of our LED bulbs. All Viribright products have a 3-year, easy replacement warranty.

LED Light Bulb Terminology

Coloring Rendering Index (CRI) – CRI represents the quality of light and its faithfulness to render colors correctly, that is, to enable us to perceive colors as we know them. The ideal CRI is 100, and some incandescent bulbs approach this level. LEDs and CFLs use different design components in trying to equal the CRI of incandescent bulbs. LED bulbs CRI ratings range from 70 to 95, and the best CFLs have ratings in the mid 80s. The entire line of Viribright A19 bulbs, for example, features a CRI of 90+ Warm White making them one of the highest in the industry.

Correlated Color Temperature (CCT) – is the measure used to describe the relative color appearance of a white light source. CCT indicates whether a light source appears more yellow/gold/orange or more blue, in terms of the range of available shades of “white.” CCT is given in kelvins (unit of absolute temperature). 2700K is “Warm”,  4000K is “Cool” and 6000K is “Daylight”. The typical light color we are used to in indoor home lighting is “warm”, 2700K.

Lumen – a unit of standard measurement that is used to describe the amount of light contained in an area as perceived by the human eye. The more lumens, the brighter the light. You can use lumens to compare the brightness of any bulb, regardless of the technology behind it, and regardless of whether it’s incandescent, CFL or LED.

In practical application, when buying a light bulb, we should look for bulbs which produce more light but consumes less energy. Understanding lumens as a measure of brightness makes it easier to select the most efficient bulb for your application. This is also important

What You Should Know About Choosing Light Bulbs

Here is how the most common types of bulbs compare:

Brightness and Efficiency

Because bulbs vary in their efficiency, it’s best to compare bulbs based on their light output (lumens) rather than their wattage (amount of energy used). The higher number of lumens, the brighter the light will be. Higher wattage bulbs use more energy. Here’s how bulbs compare.

Color Choices

Traditional incandescent bulbs emit a “warm” color. Today, bulbs are available in a range of colors:

Soft/Warm White
The standard color
of incandescent bulbs
Cool White
Good for kitchens
and work spaces
Daylight
Good for reading
and work spaces
2700K 4000K 6000K / 6500K

Shape Choices

bulb-alineA-Line (A19 or omnidirectional) bulbs disperse light at a wide angle and are ideal for fixtures used to spread light throughout the room. A-line bulbs are a good choice for room area-lighting, reading lamps, and hallways.

Spotlights (BR30, BR40) concentrate light in a small area to produce a bright spot of light. Spotlights are a good option for track lighting and overhead recessed lighting.

bulb-floodlightFloodlights (PAR30, PAR38) cast a wider directional light than spotlights. Floodlights are ideal for recessed lighting, outdoor lighting, landscape lighting, and motion sensors.

bulb-candleCandelabra and Miniature Candelabra bulbs (E12) imitate the shape of a candle and provide ambient and accent lighting. They are for use in decorative lighting fixtures, including wall sconces, decorative fixtures and chandeliers.

Bulb Base Choices

bulb-mediumMedium (E26) – The bulb base design for standard light bulbs, used in most lamps and overhead light fixtures.

Candelabra (E12) – A slightly smaller bulb base, used in chandeliers, light sconces and other small fixtures.
