277 Volts is the input power of choice for most industrial and commercial applications. High voltage lighting is better from an efficiency standpoint. Higher voltage means less current, which means less power loss from resistance as stated in Ohm’s and Joule’s laws.
Ohm’s law: Voltage = Current*Resistance
Joule’s law: Power = Voltage*Current
High voltage lighting means you can put more lighting fixtures on a given circuit because voltage drop is less of a concern. This means these lights are ideal for areas with a lot of lighting fixtures close together: think warehouses, offices, restaurants, hotels, schools, and even hospitals.
Most industrial facilities get their power in a 480/277 volt 3 phase 4 wire system, because 277 is the phase-to-neutral voltage for 480’s phase-to-phase. The 480 volt wiring is generally used to power large industrial equipment, and the 277 volt wiring powers industrial scale lighting. These two voltages tend to go together because you do not need a transformer to use the 277 voltage, which cuts down on energy and construction costs.

The beginning of 2012 marked a change in the way we thing about lighting. Earlier this year, The Energy Independence and Security Act of 2007 outlined new regulations to phase-out inefficient incandescent general service bulbs over a four-year period-in California this started a year earlier in 2011.
The phase-out process began with the 100 watt incandescent in January of this year and will be followed by the 75 watt in 2013 and the 60 watt and 40 watt incandescents in 2014. Fortunately, there are many replacement options available that provide the same quality of light but meet the new standards and you can learn more about them in the Bulbs.com Learning Center under Incandescent Phase-out.
Following the incandescent bulb phase-out, PAR Halogen and Reflector lamps will begin their own phase-out starting on July 14, 2012. To be compliant with EISA's energy efficient standards and a ruling by the Department of Energy in 2009, any parabolic aluminized reflector (PAR) or reflector bulb that is 40 watts of higher can no longer be manufactured for use in the United States. This includes PAR38, PAR30 (short and long-necked), BR30, BR40 and R20 halogen lamps. These bulbs are extremely popular with businesses and homeowners, so we have increased our inventory to meet the needs of customers during the transition period. However, as inventory supplies are depleted in the marketplace, the time will come to look at replacement options.

Much like our recent blog post about the different types of lighting for the hospitality industry, the retail industry requires just as much attention when it comes to the products you sell and the environment you are creating for your customer.
It’s safe to say that just about every manager or business owner is looking for ways to save. Energy costs from HVAC and lighting are no exception. The most common options are energy saving compact fluorescent lamps (CFLs) and LEDs. Both can produce quality light with the CRI needed for retail locations.
In the past, CFLs did not perform as well as they do today. Light quality, color temperature and average rated life of the bulb have all made significant improvements over the years. Still, it is a wise choice to purchase a reputable brand as there are some very inexpensive CFLs that often fail to meet their claim. Here is a great post if you would like to delve deeper into CFLs as an option. There are even dimmable options for spiral CFLs and CFL reflectors. Tip: Speak with one of our Lighting Specialists as some lighting controls (dimmers, occupancy sensors) are not always compatible with dimmable CFL lamps. Additionally, if you are currently using a large quantity of halogen lamps to light your space, CFLs are a great solution as they produce very little heat.

On December 16th, Congress passed a new spending bill that contained a provision that would block the Department of Energy (DOE) from enforcing new energy-efficient standards for certain types of light bulbs. As you might recall, the "incandescent bulb phase-out" stems from the Energy Independence and Security Act of 2007 (EISA 2007). A section of this Act has adopted the title of "Incandescent ban" over the last few years, except it is not really a ban at all. It simply states that certain classes of lamps will be phased-out to meet new energy efficiency standards mandated by law. We have outlined the new standards in our Learning Section, if you need a refresher.
The passing of this bill has caused a lot of confusion regarding the phase-out. The truth is, the 100 watt incandescent will still begin it's scheduled phase-out starting January 2012. The EISA of 2007 efficiency standards have not been repealed and are still the law. The only effect that the bill has on the DOE is that they do not have funding to enforce the law until October 2012.

If you’ve watched the news recently, you may have heard the controversy surrounding China’s export restrictions on a number of resources, including rare earth elements. What may not be fully clear is how this affects you as a consumer of electronics, and lighting products in particular. We’ve put this together as a quick overview to let you know what’s happening, and what to expect going forward.
First, let’s look at what rare earth elements are, and what they’re used for: Rare earth element is the common name for a set of 17 chemical elements. They are critical in the production and operation of a wide range of consumer electronics, and are also used in the phosphors that create light in a number of different light bulb types, including fluorescent, LED, and mercury vapor.

Mike Connors joined the Bulbs.com team in 2000, and was selected as Chief Executive Officer in 2009. Prior to becoming CEO, he spent several years serving as VP of Sales.
The March 2011 EcoPinion survey entitled “Lighting the Path Forward for Greater Energy Efficiency” offers interesting if not insightful commentary regarding the acceptance and usage of energy efficient lighting products by U.S. households.
It’s important to note that at first glance one might believe that a survey conducted by an organization named “Ecoalign” would be slanted in some way toward favorable opinions of energy efficient or green products because the respondents were predominantly environmentalists – This is not the case. The methodology used for the survey used a statistically significant sampling size of respondents who were targeted according to gender, age, census region and ethnicity. The sample was drawn from Survey Sampling International’s SurveySpot online consumer panel, an organization that is highly regarded as a sample provider in the market research industry.

Gregory Henderson is co-owner of the Roxbury Motel, located in the Catskill Mountain town of Roxbury, NY. He and his partner Joe Massa's unique approach to contemporary lodging has been featured in a number of publications including New York Magazine, National Geographic Traveler, and Madame, and the Roxbury was called one of the "Grooviest Motels in the U.S." by Daryn Kagen of CNN Live Today.
We asked Greg to sit down with us to discuss the Roxbury Motel, and the role lighting plays in the lodging experience.
Chris Robarge conducted the interview, and is a certified Lighting Specialist and web marketer at Bulbs.com.
