Consumer-grade LED A-lamps

Posted under Alpenglow Lighting Design News

At Alpenglow, we tested (in an unscientific manner) several LED A-lamp replacements from big-box retail stores. Although none had the lumen output of the specification-grade versions, they were close (nominal 12W lamps have approximately 800lm). The samples purchased were all labeled as being dimmable and were tested on Vantage Scenepoint dimmers.

A lamp comparison was done in a pair of identical stairwells with identical pendants. One had a 150W halogen lamp, the other a 12.5W/810lm LED lamp. Under the halogen lamp, we read 2.3 footcables, under the LED, we read 1.7fc. So, for an approximately 92% reduction in wattage, we saw a 27% light reduction. For residential use, the .6 fc drop is nearly impossible to perceive, but the reduction is power consumption will certainly affect the monthly power bill.

Of 2 LED lamps tested, the 810lm version (versus a 12W/800lm) had excellent color, good light output, and good dimmability. It should be noted that many existing dimmers are designed for loads of 40W or more, and may flicker with low wattage loads. In the case of the Vantage Scenepoint dimmers tested, they worked fine at 12.5W. However, most LED dimmable lamps will switch off at approximately 10% and will not dim all the way to off. By changing the dimming profile in Vantage’s software, we were able to tune the dimming of the lamp so that it worked fairly well.

Consumer-grade LEDs will typically cost less than specification-grade, and will typically have shorter lifespans (~25,000 hours). However, they can be purchased for $20 or less, and will still last 8-10 years in residential use. Of course, the technology will also progress and brighter, less expensive lamps will appear on the market. Based on the light output, we recommend replacing incandescent lamps with LED versions as they burn out. The savings in energy will offset the installed cost very quickly.

Even China is eliminating incandescent bulbs

Posted under Alpenglow Lighting Design News

From the Huffington Post:

China will phase out power-draining light bulbs within five years in a move to make the world’s biggest polluting nation more efficient but also certain to impact the global market.

China will ban imports and sales of 100-watt-and-higher incandescent bulbs from Oct. 1, 2012, in an attempt to save energy and curb climate change, China’s main planning agency said Friday.

Bans will also be imposed on 60-watt-and-higher bulbs from Oct. 1, 2014 and 15-watt-and-higher old-style bulbs from Oct. 1, 2016. The time frame of the last step may be adjusted according to an evaluation in September 2016, the National Development and Reform Commission statement said.

State-run Xinhua News Agency quoted Xie Ji, deputy director of the NDRC’s environmental protection department, as saying China is the world’s largest producer of both energy-saving and incandescent bulbs and so the plan will also “have a significant impact” in reducing the use of incandescents worldwide.

Last year, 3.85 billion incandescent light bulbs were produced in China and 1.07 billion of them were sold domestically, the agency said. Power consumption for lighting is estimated to be about 12 percent of China’s total electricity use, it said.

The statement said China will save 48 billion kilowatt hours of power per year and reduce emissions of carbon dioxide by 48 million tonnes annually once the bulbs are phased out.

Several countries plan to phase out traditional light bulbs. The United States will ban the making and sale of incandescent light bulbs beginning in 2012. The 27-nation European Union agreed in 2008 to phase out the bulbs by 2012.

Latest project near completion: ProBike Tucson

Posted under Alpenglow Lighting Design News

Alpenglow is excited to be working with ProBike in Tucson, Arizona to design their new store. Along with lighting and controls design, Alpenglow has branched out into interior and casework design. The new store is located at 6540 E. Tanque Verde and should be open in mid-October. Construction is progressing, and every day they seem to add more bicycles and services. If you’re in Tucson this fall, come down to visit the shop as you prepare for El Tour.

Other fun and interesting projects due to wrap up soon include a collaboration with Crystal Glass Studio and Design Project for a pair of custom pendants, and the renovation of New Castle Branch Library with A4 Architects and B&H Construction.

The Collateral Damage of the Energy and Security Act

Posted under Alpenglow Lighting Design News

The Energy and Security Act of 2007 has gained attention recently (despite its age, people seem to have suddenly discovered it), and while there has been a great deal of teeth gnashing and lightbulb hoarding, no one has addressed the approaching death of a cultural phenomenon: the lightbulb joke.

When we switch over to long-life LEDs for our light sources, we will extend lamp life from about 1,000 hours to 50,000 hours. Commercially, this is over 10 years, and residentially, over 20. My 4-year-old son will be out of college before my new LEDs burn out, so he will rarely, if ever, change a lightbulb.

He just won’t get jokes like:

Q: How many telemark skiers does it take to change a light bulb?
A: 4. One to do it, the others to say, “Sweet turns, bro.”

Q: How many ski instructors does it take to change a light bulb?
A: 4. One to do it, the others to tell them how they did it wrong.

Q: How many union stage hands does it take to change a light bulb?
A: Straight show or musical?

As we leave Edison’s 1880 invention behind in history’s dustbin, and we replace it with light bulbs that no longer waste 90% of their energy as heat, we will lose this most cherished part of our culture. Sadly, the lightbulb joke will soon seem as dated and quaint as “You Might be a Redneck” and Saturday Night Live’s Belushi Era. All we’ll be left with is LOLZCats and Justin Bieber jokes.

Oh, the humanity.

The Light Bulb is Dead! Long Live the Light Bulb!

Posted under Alpenglow Lighting Design News

Recently, people have discovered that a Federal Law enacted in 2007 is going to eliminate 130-year-old technology. An article in the New York Times Magazine this weekend discusses the matter. What amazes me is how a visionary like Howard Brandston, one of the greatest lighting designers, is so opposed to the end of incandescence. His innovative imagination is hampered by his inability to move on from old technology.

Here at Alpenglow, we welcome new technology, particularly when it offers huge energy and money savings. As the NYT article points out, the patent on the incandescent light bulb dates to 1880, and it’s replacement can save 200 MILLION tons of CO2 per year. Although the cost of LED bulbs is relatively high ($30-80), consider that Edison’s bulb cost the equivalent of $10 in its day, and lasted 1/50th as long as an LED. Even today, a  25-cent incandescent lasts the same as edison’s bulb, about 1,000 hours. Edison also did not care about energy efficency when he designed the bulb, since he also owned the utility.

The cost of electricity is continuing to climb, with our local utility about to raise residential and commerical rates next month. Now is a great time to consider upgrading your lightbulbs to new tachnology. Contact Alpenglow to ask how we can help you.

Lighting Controls

Posted under Alpenglow Lighting Design News

Recently, Alpenglow was contacted to evaluate a lighting control system in a private residence. The residence is at the base of one of the premiere ski areas in the country and is about 10 years old. We discovered that the house contained a small system which controls only the kitchen and parts of the living room, and it does not have the capability to control other areas, integrate with AV, HVAC, blinds, or anything else.

Here is a Control station located adjacent to a light switch

Here is a Control Station in another residence.

Quick Quiz: which is easier to operate?

Controls actually simplify lighting, but only if they are designed properly. Alpenglow can help you create an easy-to use, stable, and upgradable system. Contact us today!

Aspen Historical Society

Posted under Alpenglow Lighting Design News

Last week Alpenglow re-lamped the display rooms at the Aspen Historical Society, using the existing track fixtures and replacing 50W halogen MR-16 lamps with 9W LED MR-16s. The new LEDs are available in 30, 45, and 60 degree beam angles. The connected lighting load was reduced by 80%, and the lamp life extended from 2,000 hours to 50,000 hours. This will not only help AHS save money in electricity use, but also reduces labor for relamping. Photos are posted in the Educational Portfolio. Contact Alpenglow today to lean how LEDs can help save you money and energy.
