Recycling Center to Take Fluorescents from Non-Residents

The El Cerrito City Council gave a green light to accepting fluorescent light bulbs and tubes, for a fee, from people who don't live in El Cerrito or one of the other West Contra Costa cities that already pay a solid waste fee. Fluorescent light bulbs and tubes can be friendly to the environment by requiring less electricity than other light fixtures, but they can be far more hazardous if they break and release toxic mercury.

LEDs deliver better light, but consumers buy CFLs

Of the 90% of Americans who have used LED or CFL light bulbs to save energy and cut costs, most use CFLs, according to a Consumer Reports study released Thursday. Almost 75% of consumers who have switched from incandescent bulbs currently use CFLs. About 25% use LEDs, or light-emitting diode bulbs, even though LEDs use 75% less energy than traditional incandescent bulbs, last as long as 25 years, brighten immediately and often offer better light quality than compact fluorescents.

How LED technology is key to future smart buildings

Cost and functionality have traditionally been two big hurdles for the widespread use of LED lighting technology in commercial buildings. With technical improvements and increasing awareness of LED energy efficiency beneits, there has been some limited adoption in parking and exterior applications. But the convergence of building automation and information technology that is transforming the facilities management industry - and helping define the smart buildings market - presents a significant opportunity for deployments in LED (light emitting diode) applications.

LED Tube Light Trend Report: The High Performance LED Tube

The High Performance LED tube has the capacity to fundamentally change the commercial American energy landscape. An LED tube can typically reduce the electricity by 50% or more over an incumbent T12 or T8 fluorescent tube. However, “high performance” is the key since industry professionals, like electrical contractor, have had reservations about the cost-benefit ratio, longevity, and the overall quality assurance of LED tubes. The reservations have stemmed from the “new” factor, engineering viability, and observations that the vast majority of mass-market LED tube lights are imported from China.

For instance, the 3W and 5W LED bulbs can replace 20W and 40W incandescent bulbs, and their lamp holder is E14, E22, E26 and E27 respectively.

Don't be left in the dark by these four lightbulb letdowns

Replacing a lightbulb isn't as easy as it used to be. The new energy-saving bulbs may not give off the type of light you're used to. In fact, some of the compact fluorescents and light-emitting diodes in Consumer Reports lightbulb tests give off a ghastly light color, or are dim. And there are some CFLs that take three minutes to fully brighten—that's enough time to make toast. But among the duds we also found bulbs that dazzled. Here are four lightbulb letdowns and how to avoid them.

Cree Illuminates Seven Newport News Public Schools

Newport News Public School District in Virginia recently installed more than 185 Cree, Inc. exterior luminaires, becoming the first Virginia school district in the area with a significant LED lighting installation. The district selected Cree THE EDGE security, area and parking structure luminaires to illuminate the exteriors of seven schools: General Stanford Elementary, Greenwood Elementary, Lee Hall Elementary, Palmer Elementary, Crittenden Middle, Booker T. Washington Middle and Denbigh High.
In 2008, Newport News School District spent $5.6 million on energy costs. In the past four years, the school district has implemented a number of energy-saving projects, including the installation of Cree LED luminaires. Officials estimate the LED lighting upgrade resulted in significant annual energy savings of 139,000 kWh and reduction in annual lighting energy costs at the seven facilities by 65 percent, reducing carbon emissions by 191,000 pounds. Officials also estimate a payback of three years for the installation and expect ongoing operational savings due to the extended lifetime of Cree® luminaires and the reduced maintenance needs.
THE EDGE luminaires replaced 189 high-pressure sodium and 150 incandescent fixtures, delivering enhanced color quality, uniformity and optimized illumination performance to each of the school's exteriors. The parking lots at all seven schools now meet the sustainable illumination requirements of each school, which helps reduce energy and maintenance costs for the district and tax payers.

Do they really save you money?

You’ve heard all of the buzz about energy-efficient light bulbs, but with the cost per bulb, you’re not too sure you believe they can really save you money. Well, the truth is, they can. Compared to traditional incandescents, energy-efficient light bulbs, such ashalogen bulbs, compact fluorescent lamps (CFLs) and light emitting diodes(LEDs), use less energy and last much longer. While the initial price of energy-efficient bulbs is higher than traditional incandescents, newer bulbs cost less to operate, saving you money over the life of the bulb. Since many of the newer bulbs last significantly longer than traditional bulbs, so you won’t need to replace them as often.

LED Price for Backlight Application Slides in 3Q12

According to LEDinside, the LED research division of TrendForce, despite the rush orders during 2Q12 which kept LED chip and package makers’ utilization rates high, the 3Q12 outlook for LED backlight market turns murky due to the European debt crisis and the weak demand in China. No demand surge is in sight due to the weakened market confidence and the conservative attitude of LED companies. Whether or not brand vendors will cut orders in 3Q12 depends on the sales of end-market products.

Guangdong strengthening LED technology base

LED Grow Lights Make Big Showing

San Francisco has become a Mecca for indoor gardeners each July by hosting the largest show for hydroponics equipment in the US. Consumers and store owners from around the world flock to the Indoor Gardening Expo each year, to get an inside look at all of the latest products and developments from their favorite brands.
One of the newest products to the hydroponics industry is LED Grow Lights, with several well-known manufacturers in attendance at this year's show. The show is one of the only places consumers will see products from Hydro Grow, Kessil, Lumigrow, Apache Tech, California Lightworks, and others on display in one room for all to compare. After comparing all of the LED Grow Light companies at this year's show, one of them literally stood out above the rest.   
The largest of the booths for LED Grow Lights this year belonged to Hydro Grow, who also had the largest product showing of any LED Grow Light manufacturer. Their booth towered over all others located on the same floor, with "Extreme LED Grow Lights" displayed 10 feet in the air for all to see. The Hydro Grow booth was truly unique, with a Feng Shui design showcasing their round 21X-PRO and square 84X-PRO models over beautiful flowering plants. On top of this was the first ever public side-by-side comparison of a 1000W HPS and their latest 336X-PRO LED Grow Light.
The "X2" LED Grow Lights as they are called, are the latest incarnation of the Extreme LED product line manufactured by Hydro Grow. X2 replaced the X1 models developed in 2011, delivering 25% more intensity to consumers in a smaller overall form factor. "The secret to our intensity" stated Donnie, "is our patent-pending X-Lens technology which concentrates the output from the LEDs. The X-lens gives our products up to 6x more intensity vs. standard lenses used in competing LED Grow Lights." Aside from the lensing which was unique to Hydro Grow, was their modular build platform. The X2 lights were the only in attendance using a modular design wherein each part operated and was serviceable independent of the others.        

The Secret Of Liquid-Cooled LED Bulbs

Trumpeted as the “best kept secret in the LED market”, SWITCH Lighting’s CEO Tracy Bilbrough has revealed details about the company’s core technology - the LQD Cooling System - for the first time at the LED Show in Las Vegas. The LQD Cooling System is a method of keeping LED light bulbs cool using a liquid silicone coolant. The central nervous system of a LQD Cooling System combines of two proprietary components: a coolant made of liquid silicone and an efficient and reliable driver.
Liquid silicone is no stranger to thermal-management applications from cooling large machinery to being an ingredient in select food and cosmetic products. Reported as being a completely safe, food-grade product, liquid silicone is electrically non-conductive, non-toxic, non-staining, and does not degrade LEDs. Pairing the coolant and drivers, this system works in synchronization to cool the LEDs in the bulb as well as all integral components.

White LEDs printed on paper

PhD student at Linköping University in Sweden, Gul Amin has demonstrated in his doctoral thesis that white LEDs, made from zinc oxide and a conducting polymer, can be manufactured directly on paper. It is possible to print them on wallpaper, for instance. The active components are nanorods of zinc oxide on a thin layer of polydiethylflourene (PFO), a conducting polymer. The paper has first been coated with a thin, water-repellent, protective and leveling layer of cyclotene, a resin

In the first phase, the conventional lamps of the mazar’s ground floor chandelier, basement chandelier and the museum illumination were converted to the LEDs.

Flexibility And Intangibles, Not Energy Efficiency, Will Drive LEDs Market

Light-emitting diodes (LEDs) will soon dominate the lighting market. Few (if any) market watchers would disagree with that statement. In fact, analysts at A.T. Kearney predict that LEDs could capture as much as 90% of the lighting market by 2020. More energy efficient and longer lasting than incandescent or compact fluorescent (CFL) light bulbs, LEDs are also mercury free. Despite not having much exposure to this rapidly growing, if immature, market, consumers seem to know two things: LEDs are (for now) more expensive than the alternatives at the time of sale and they save energy. Indeed, the acronym itself, LEDs, has become a byword for energy efficiency.
