Is now the right time for LEDs?
According to the U.S. Department of Energy, 22 percent of electricity used in the U.S. powers lighting, and the typical American home has 40 sockets for light bulbs. According to the DOE, switching to LED (light emitting diodes) lighting in the next 20 years could reduce electricity demands from lighting by 62 percent and eliminate 258 million metric tons of carbon emissions.
Switching to LED-based lighting can save 40 to 70 percent of the electricity a city uses for certain lighting applications such as parking garages, parking lots, outdoor public areas, street and portable lighting.
Technological advances in LED lights is happening at incredible speed. Today, everything from traffic lights, billboards, car headlights, and laptop computers use some sort of LED for a light source.
According to Raja Parvez, president and CEO of Rubicon Technology, LEDs have many advantages, including:
- Low energy consumption — ENERGY STAR qualified residential LED lighting uses at least 75% less energy
- Long service life – ENERGY STAR qualified LED lighting lasts 25 times longer than incandescent lighting
- Directional distribution of light
- No infrared or ultraviolet radiation – excellent for outdoor use because UV light attracts bugs and LEDs don’t
- Safety and environmentally conscious – LEDs contain no mercury and remain cool to the touch
- Fully dimmable while CFLs are not
GE introduces new LED light bulb
The inventor of the first visible light-emitting diode makes history again this year as it begins to show customers a 40-watt replacement GE Energy Smart® LED bulb available later this year or early 2011. GE Lighting’s new LED bulb is expected to consume just 9 watts, provide a 77-percent energy savings and produce nearly the same light output as a 40-watt incandescent bulb, while lasting more than 25 times as long.
The new GE Energy Smart® LED bulb is expected to outperform currently available products that may be underwhelming consumers right now. GE scientists and engineers designed the bulb to better direct light downward on the intended surface and all around, not just out the top of a lampshade, as most current LED bulbs are prone to do. The new GE LED bulb offers 450 lumens—the Energy Star® threshold to be considered a 40-watt incandescent replacement. Currently available LED bulbs produce 350 lumens or less. GE has filed multiple patent applications for the bulb and expects it will be an ENERGY STAR®-qualified LED omnidirectional light bulb.
“This is a bulb that can virtually light your kid’s bedroom desk lamp from birth through high school graduation,” says John Strainic, global product general manager, GE Lighting. “It’s an incredible advancement that’s emblematic of the imagination and innovation that GE’s applying to solve some of the world’s biggest challenges.”
GE Energy Smart® LED bulb product snapshot:
- Expected to consume just 9 watts—compared with 40-watt incandescent/halogen or 10-watt CFL, while delivering nearly the same light output;
- Expected 25,000-hour rated life—will last 17 years (4 hours per day), which is 25 times longer than a general service 40-watt incandescent or halogen bulb and more than 3 times longer than a standard 8,000-hour rated life CFL;
- LED technology delivers the instant full brightness of an incandescent or halogen bulb;
- Durable solid-state design with no filament to break;
- Contains no mercury and will be RoHS compliant; and
- Feels cooler to the touch than CFLs and far cooler than incandescent bulbs.
The 9-watt GE Energy Smart® LED bulb, a replacement for 40-watt general service incandescent bulbs, hits store shelves this fall or in early 2011. Retailers set pricing but it is expected to be $40 to $50. The new bulb joins GE’s growing family of LED bulbs in a broad range of shapes, wattages and colors, including, spot and flood lights (PAR20 & PAR30), ceiling fan bulbs (A15), medium globes (G25), small globes (G16.5), candles (CA10), and night lights (C7). All of GE’s Energy Smart® LED bulbs are rigorously tested to ensure constant color, long life and verifiable lumen ratings.

GE will put prototypes of the bulb—outfitted with Cree XLamp® XP-G LEDs—on display at two upcoming trade shows: Light + Building 2010 in Frankfurt, Germany, and LightFair 2010 in Las Vegas, Nevada, USA. The high-efficiency, high-lumen-output LEDs used in the GE bulbs are Cree’s smallest and brightest lighting-class LEDs, designed specifically for general lighting.
“The introduction of high-quality retrofit light bulbs, like the GE Energy Smart® LED bulb, is a key next step in the LED lighting revolution,” notes Norbert Hiller, Cree vice president and general manager, LED Components.
Strainic adds: “Consumers have been reluctant to move away from less efficient incandescent bulbs because they love the light quality. This new GE Energy Smart® LED bulb will address that lighting preference head-on and give consumers yet another option to light their homes and businesses.”
New Lighting Legislation
Starting in 2012 and continuing through 2014, standard incandescent light bulbs are going away as a result of U.S. federal lighting efficiency standards:
- 100-watt bulbs can no longer be made in January 2012;
- 75-watt bulbs can no longer be made in January 2013; and
- 60- and 40-watt bulbs can no longer be made in January 2014.
GE has consumers covered each step of the way with alternatives such halogen, CFL and LED bulbs that already meet the new efficiency standards.
Bulbrite video looks at broad range of lamping styles
A video from Bulbrite reviews a broad range of new lamping styles, including new Halogens, CFLs (Compact Fluorescents) and LEDs (Light Emitting Diodes).
Effective January 1, 2012, the household light bulb (as we know it) will no longer be manufactured. U.S. Congress mandated that all general service light bulbs, produced as of this date, must be up to 30% more energy efficient than current standards require. To comply with this legislation, Bulbrite has introduced the Eco-Friendly Halogen A19, which fits all standard and dimmable lighting fixtures. Consumers will gain the benefits of higher efficiency and superior lighting quality with the Eco-Friendly Halogen A19 bulb.
Consumers looking for CFL lighting should know Bulbrite offers a variety of new, high performance compact fluorescent light bulbs that are also aesthetically pleasing. This line features a broad range of sizes and styles, including the popular Energy Wiser™ brand.
Bulbrite’s high-quality, high-performance Chandelier LEDs are energy efficient alternatives to traditional chandelier light bulbs. These LEDs provide high quality Warm White Light and are available in a candelabra base and a medium base. Candelabra base bulbs produce up to 15 watts using only 2 watts of energy while medium base bulbs produce up to 25 watts using 3 watts of energy consumption, compared to standard incandescents. The unique design and engineering of high-powered miniature LED chips allow the Chandelier LEDs to deliver 360-degrees of total illumination. They are available in a Clear finish for maximum light output and a Frosted finish for a more traditional look.
The video also captures Bulbrite’s new generation of high performance LEDs, highlighted by the TURBO series, featuring a state-of-the-art, revolutionary design. TURBO LEDs offer innovative heat sink technology that eliminates the need for large, aluminum heat sinks and clunky housings. The new LEDs include an innovative cooling system featuring pure anodized aluminum thermal fins. With an IP 65-rating, the LEDs are totally protected against dust and low-pressure water from all directions, for indoor and outdoor use.
C.Crane Company introduces the GeoBulbTM
Energy-saving LED light bulb lasts 30 times longer than incandescent bulbs and operates at a fraction of the cost
C. Crane Company, a pioneer in LED (light-emitting diode) flashlights, has developed the GeoBulbTM, an LED light bulb that uses half the energy of a compact fluorescent bulb, contains no hazardous mercury or lead and lasts for up to ten years of daily use. GeoBulbTM, the first high light output, direct-replacement LED light bulb that uses just 7.5 Watts of power to produce as much light as a 60-watt incandescent bulb, is available now exclusively from C. Crane.
GeoBulbTM brings LED light bulbs up to the brightness of incandescent bulbs, while maintaining the qualities that make LEDs so very exceptional:
- GeoBulbTM lasts 30,000 hours or up to ten years with typical use;
- GeoBulbTM generates very little heat and is not susceptible to vibrations or repeated on/off switching;
- Through quantum-well technology, the GeoBulbTM uses only about 10% of the power of incandescent bulbs and about half of a comparable compact fluorescent bulb (CFL).
“The persons that have come together to design the GeobulbTM have the vision and purpose to reduce worldwide energy usage by 10%,” said Bob Crane, President, C. Crane. “It will take many years to accomplish this goal but the GeoBulbTM is here. The GeoBulb II™ Cool White High Powered light bulb reduces the amount of energy used over incandescent by up to 87% and significantly over Compact Fluorescent Bulbs.”
GeoBulbTM is available in three light color spectrums: cool, soft and warm. Each GeoBulbTM uses only 7.5 watts of electricity and has an expected life span of 30,000 hours or approximately 10 years with eight hours of daily use. GeoBulbTM is available exclusively from C. Crane’s retail store, web site or catalog and every GeoBulbTM is backed by a three-year warranty, valid even if the bulb is used for 24 hours a day, seven days a week or for three consecutive years.
The retail price for GeoBulbTM is $119.95, which over the 30,000 hour lifespan of the bulb, actually makes it less expensive to purchase and operate than a traditional incandescent bulb:
The GeoBulbTM has passed conductive and radiated emission tests from the FCC, also passed UL safety tests and is Lead Free, making it RoHS compliant. The GeoBulbTM is designed for indoor use only, in an open fixture and within a temperature range from 14-104°F.
For over 25 years, C. Crane Company has been an innovator in the electronics industry and design. A forerunner in LED lighting sales and technology, they began their research and development of multiple white LED flashlights in 1997.
