Why 277 volts for lighting?

by Elizabeth Karpinski 10 June, 2015 03:38

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.

LIGHTFAIR International 2015 was held last week at New York City’s Javits Center. If you know anything about the lighting industry, you know that this is the event to attend. This year LIGHTFAIR saw more than 26,000 attendees walk through the doors to view the latest LED light bulbs and solid state lighting (SSL) products. It’s an opportunity to explore state-of-the-art technology, network with like-minded professionals, and attend educational sessions. Many manufacturers use the conference to announce new products that will be available at some point later this year.

The exhibition hall was jam-packed with attendees and manufacturers, and featured a number of exciting new product announcements. Gaining control of lighting and improved light quality and design were by far the popular themes this year.  If you missed LIGHTFAIR this year or have never even heard of it, this is LIGHTFAIR in Review.


Top 5 Ways to Go Green in 2015

by Harrison Chute 21 April, 2015 12:01

This Earth Day, Bulbs.com is counting down our favorite ways to go green, with some practical tips and considerations to keep in mind during the celebration of our planet and throughout the year.


LED Lighting phase-out, April 2015

by Christina Crow-Dufault 1 April, 2015 07:37

On December 16th, Congress passed a bill with a provision to enforce new energy-efficiency standards for certain types of light bulbs, mostly affecting Light Emitting Diodes, or LED lighting. This "LED bulb phase-out" stems from the Energy Independence and Security Act of 2007 (EISA 2007). A section of this Act has come under the label of "LED bulb ban" with most major media outlets since the announcement, despite not technically being a ban. It simply states that certain classes of LED lamps will be phased-out in order to meet new efficiency standards mandated by law.

Lighting Phase-outs & Regulations

Earth Hour: Lights Out for the World...Sort of.

by Harrison Chute 24 March, 2015 12:29


To give back to the entire planet, we offer a single hour — a day at most? What is this Earth Hour, and why does it matter?

Earth Hour is an international movement started by the World Wildlife Fund, encouraging you to switch off non-essential lights for one hour, and perhaps more critically, to inspire a trend toward engagement with energy efficiency and environmental awareness.

This year, Bulbs.com will be participating in Earth Hour, a World Wildlife Fund sponsored world-wide event happening this Saturday March 28th from 8:30-9:30 PM.During Earth Hour, we will be turning off non-essential building lighting and encouraging our employees to do the same in support of a broad range of environmental issues. Additionally, Bulbs.com supports the transition to energy efficient LED lighting and its positive environmental impacts.

Outdoor Lighting Tips

by Christina Crow-Dufault 14 March, 2013 10:00

While the bottom half of the country is getting warmer, those of us in the northern states are starting to defrost.  As the spring season approaches, we start to think about projects in and around our homes.  You might refer to yourself as a Weekend Warrior or an avid DIYer.

Whatever you call yourself, the outdoor season is coming and it’s the perfect time to start thinking about your yard! And with all the work you put into your landscaping, why not show it off into the evening hours. Plus, you can add a little more security to your home with entry way spot lights and dusk-to-dawn sensors.


Lighting for Property Managers: Time for a Change?

by Christina Crow-Dufault 2 October, 2012 11:15

For decades, choosing a light bulb was a fairly simple task. We didn’t have all these choices we now have today. Wattage meant brightness and we didn’t have to worry about dimmer compatibility.  

Yes, there is a lot of new products and information out there now, but that’s okay. Change is good.

These new products can help us save energy, money and the planet through innovative, lower-wattage, long-life products that don’t produce nearly as much pollution during the manufacturing process as older types of lighting. 

Products such as CFLs and LEDs will help to reduce your energy bills, labor costs and even HVAC related costs. And as a Property Manager -of one location or many- that can make all the difference.

Phased-out bulbs, new efficiency standards, updated packaging labels and LED improvements over the last few years have presented some challenges, but they have also opened up a number of opportunities.

Whether you’re upgrading for the first time from incandescent to CFLs or you’re making the move to LEDs, here are some things you should keep in mind. 


Lighting for Distributors: Staying ahead of the Curve

by Christina Crow-Dufault 24 July, 2012 05:27

As a distributor of lighting products it can be challenging and often time consuming to find the right products for your customers’ needs.  Also, constant changes in technology and recent government legislation can make it difficult to keep up. Most recently, LED lighting and the PAR Halogen/T12 Fluorescent lamp Phase-out have been keeping us busy.  Here are a few things you should know:

LED lighting

LED BulbsLED lamps are becoming more popular by the minute!  The good news is that this technology is rapidly improving and in turn, the cost is decreasing. Yes, LEDs may still come at a higher cost, but consider these worthwhile benefits:

  • Reduced energy costs-LEDs use 75-90% less energy than halogen and incandescent lamps.
  • Reduced labor costs-Long life means you don’t have to change your bulbs as often.
  • Reduced HVAC costs-Halogens put off high amounts of heat, make the switch and turn down you’re AC!
  • Utility Rebates for being an Energy Saver-check with your local utility provider for offers.


Halogen Phase-out: The Facts

by Christina Crow-Dufault 6 July, 2012 11:17

Halogen PAR reflectorThe 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.


Lighting for Retail: Make Your Products Shine!

by Christina Crow-Dufault 7 May, 2012 04:02

Retail store lightingMuch 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.
