Finding High-Wattage LED Replacement Bulbs

In the lighting world, there are few bulb configurations as popular and widely used as halogen PAR38 bulbs. These sturdy and versatile lamps have found their way into just about every location in our modern lives. We use them in businesses and homes, inside and out. We love our PAR38 light bulbs—but we hate to pay for all the electricity they use. Another problem with them is that after July, standard halogen PAR38 bulbs will no longer be available in the United States thanks to the next round of light bulb bans. Although they have been a long time coming, there are now several LED options available, some of which you would actually consider buying.

Switching to LED: What Can It Save You?

Some of us resist the switch to efficient lighting, even some who embraced the compact fluorescent, just can’t seem to accept LED lighting around the house.

Look For More LEDs In 2014 As Old Bulbs Die Out

Consumers in the United States have been witnessing the gradual disappearance of old general-purpose incandescent light bulbs from store shelves since 2012. This is happening because of the adoption of the Energy Independence and Security Act of 2007, which bans the manufacture and sale of certain bulbs. The 100-watt bulb was the first to go, phased out in 2012. It was followed by the 75-watt bulb this year. Now, as 2014 begins, 40- and 60-watt bulbs will begin to disappear as well. Retailers will be able to sell existing inventory, but no new bulbs with these wattages will be made.

US consumers will have to find alternatives to the popular 40- and 60-watt incandescent bulb that has been a mainstay of homes for more than a century. The ban on general-purpose incandescent bulbs takes effect January 1, 2014.

Popular Texas Hotel Lights Up With LED

Austin, Texas is one of the great party towns of the Southwestern United States. Ask anyone west of the Mississippi River where a good place to hear live music is, and they will tell you without hesitation, Austin, Texas. The city is well known for its live music scene that has introduced generations of TV viewers to it, and all of the genres that it encompasses, through the long running series, Austin City Limits. So it’s only logical that if people flock to Austin to see live bands, they will need a place to stay after the show. Cue the Austin Hilton.

LED Lighting Doing Great Things For Schools

Recently school use of LED lighting has been the subject of conversation for school officials and policymakers who hope to cash in on the cost savings and other benefits of using LED. Even though this topic is popular now, educational institutions have slowly and quietly been moving to LED lighting for several years with a great reception from teachers, students and administrators.

Philips Lighting Claims R&D System Efficacy Achievement for LED Tube

By: Maury WrightLEDs Magazine

Philips Lighting has revealed laboratory work on an LED-based replacement for fluorescent tubes in which a so called TLED (Tube lighting LED) tube delivered 200 lm/W, including the driver, at a 3000K warm-white CCT. The company said it will bring such a solid-state lighting (SSL) product to market in 18 months to two years.

Philips chose to announce the lab project because of the magnitude of the opportunity for energy savings. Jy Bhardwaj, senior vice president or research and development, said 50% of global commercial lighting uses fluorescent tubes. The best such fluorescent lights operate in the 100-lm/W range so efficiency in that application could double in two years.

Philips_TLED_protoIn the US, fluorescent lights consume 200 terawatts annually according to Philips. The company said retrofit of all such lighting with 200-lm/W tubes would be the equivalent of 50 medium-sized power plants. Continue reading

Lighting Like an Incandescent, Except It’s an LED

By Gregory Schmidt

In the debate over the merits of incandescent light bulbs versus compact fluorescent lamps, LED bulbs have become a viable alternativeSwitch Lighting is hoping to ride the wave of rising consumer interest with its own series of LED bulbs.

Switch assembled a team of engineers and physicists in its Silicon Valley headquarters in 2007, and produced a bulb last year with distinct design that has won several innovation awards.

The bulb incorporates technology that Switch calls a LQD cooling system, a patented design that bathes the LED with a coolant made of liquid silicone. The liquid diffuses the light over the surface of the bulb, producing light that is omnidirectional and illuminating a room similar to the way an incandescent does. The shape is similar, too, for those who prefer traditional A-series light bulbs. Continue reading

How LED Lighting Could Help Cut Food Waste

From Green Business

supermarketledChanging the light bulbs could help supermarkets reduce the estimated 300,000 tons of food waste they produce each year, according to one lighting company.

Welsh firm Sedna LED reckons illuminating fresh produce with light bulbs that emit heat causes food to sweat in its packaging, contributing to the food waste mountain that costs retailers millions of pounds each year.

As a result, the company is arguing that in addition to cutting energy bills, LED lights could also help keep food fresh. Continue reading

New Lighting Standards in 2012

Beginning in 2012, common light bulbs sold in the United States will use 25 percent to 80 percent less energy. The new bulbs offer a wide range of color and brightness. Many of them last longer than traditional bulbs. Lighting standards phase in from 2012-2014 and don’t ban any specific bulb; they state bulbs need to use about 25 percent less energy. Continue reading
