Philips Lighting Questions Proper Light-Level Standards for Office Workers

iifphilipsnews031815Philips Lighting has issued a challenge to the regulatory bodies that specify light levels for various commercial-workplace scenarios to reconsider specifications given the broad age range in the workforce. In office scenarios, for instance, Philips said the 500-lx (50-fc) level that’s typically specified for office task lighting is insufficient for workers of age 45 and above. Moreover, Philips has released a widget using Facebook that allows office workers to test the light level in their own office setting. Continue reading

EPA Issues Directive on LED and Legacy Lamp Verification Testing for Energy Star

The US Environmental Protection Agency (EPA) has issued a guidance document intended to instruct certification bodies (CBs) in their implementation of verification testing of lamps, including LED-based products, that are certified to the Energy Star lamps V1.0 and V1.1 specifications. The guidance covers mandatory and randomly-selected tests and defines limited cases in which verification testing can differ from the original certification testing.

EPA Issues Directive on LED The EPA spent the summer and early fall finalizing the Lamps V1.1 specification. That document includes slight changes from the Lamps V1.0 specification published in the fall of 2013. For now, lamps can be tested to either document while the agency works on the next lamps specification. Continue reading

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.

LEDs Turn Out The Light On Incandescents And CFLs

Most people have accepted that it’s all but over for old incandescent bulbs. But CFLs—compact fluorescent bulbs, the titular replacements for incandescents—may be rapidly becoming extinct as well.

Light bulbs have evolved from the standard incandescent (right) to compact fluorescents and now LEDs (left), which come in a variety of shapes -- some quite familiar in appearance.

Shine On, You Crazy Lightbulbs

The other day I found myself at a loss in the light bulb aisle of my hardware store. I might as well have been shopping for a carburetor. There were too many options with too many symbols and verbiage that I couldn’t decipher (LED, CFL, halogen, lumens, Kelvin, CRI), not to mention all of the various brands (GE, Philips, Cree, EcoSmart — each with its own packaging lingo). Since when do you need an electrical engineering degree to buy a light bulb?

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.
