Smart Lighting: What You Should Know

Everything in our lives is getting smarter. Our phones, cars, homes, TVs, and more have all been labeled as “smart” products, invariably making the products of old appear “dumb.” The lighting world is in its own Smart Lighting revolution, as many products are jumping into the new age. More...

Energy Star 2.0 - What's New and Why It Matters

by Daniel MacLeod 12 August, 2016 10:35

EnergyStar – the US Department of Energy’s green-product certification program – is undergoing some major guideline updates in the next six months, and it could have a big impact on any pending or ongoing lighting projects.

Beginning January 2nd, 2017, Energy Star Lamps V2.0 will replace V1.1 as the qualifying directive for all light bulbs sold in the United States. The aim of the new certification standards is multi-pronged: To increase overall efficacy levels (light output per watt consumed), to include some increasingly popular new product types, and to improve harmonization between EnergyStar lighting specifications. Essentially, the new certifications aim to encompass more bulbs and drive even greater energy savings in the lighting world.

In fact, according to EnergyStar, if all light bulbs sold in the US next year meet the V2.0 requirements, electricity savings will amount to over $4 billion per year and reduce more than 54 billion pounds of annual greenhouse gas emissions – The equivalent output of more than 5 million vehicles.

Nokero: Lighting the Way to a Brighter Future

by Gabrielle Sobolewski 11 August, 2016 11:43

 

It is an unchallenged belief that humans have certain basic needs for survival—food, water, and sleep, for example. However, while these things may account for an individual’s biological and physiological needs, there are many other things we humans need to thrive as opposed to purely survive. One of those things is a gift that millions of people take for granted each and every day: light. For many of us, light is simply a way of life; and, as a result, we are becoming exceedingly reliant on its steadfast presence.

Every night, millions of people around the world struggle to overcome darkness. While some sleep, others attempt to work and study deep into the night. According to the International Energy Agency, 1.2 billion people—17% of the world’s population—–did not have access to electricity in 2013. These individuals, therefore, are forced to turn to non-renewable light fuel oils such as kerosene for light. This dependence on kerosene lamps then leaves behind a large ecological and economical concern to be addressed. More...

Energy Efficiency: Ways to Save in the Classroom

by Allison Kelley 16 November, 2015 10:45

Each year, America’s schools spend more on energy than they do on textbooks and computers combined according to ENERGY STAR®. After salaries and benefits, utility costs are the largest operating expense for school districts and strained budgets often lead to fewer maintenance and energy efficiency upgrades, compounding these issues. With this in mind, it is important for school districts to identify affordable, energy-reduction strategies to lessen this financial burden. Lighting upgrades are a good start.

Lighting typically represents around 26% of a school’s energy consumption and fortunately, lighting is one of the few expenses which can be easily reduced. Retrofits can save between 30 and 50 percent of energy costs without negatively affecting the classroom experience. Read on for tips on how to select the most effective, energy-efficient lighting system for your school.

 

Inside a classroom, it is important to maintain comfortable lighting. Students should not have to strain their eyes to adjust between tasks on their desks and the board. Minimizing high-contrast lighting can help improve mood, concentration, and visual comfort. Each of these factors enables better learning.LED recessed troffers and pendant fixtures are often great mechanisms to create even, uniform light which minimizes contrast. Additionally, troffer retrofit kits, which come with built-in bulbs and ballasts, make transitioning to energy efficient lighting stress-free. These fixtures are often fully dimmable, allowing for versatile classroom lighting.

Classroom lighting must be versatile and controllable due to the variety of teaching methods that require different light levels. During a creative period of artwork, reading, or social time, daylight glare should be controlled. Choose lighting which provides 30-50 foot-candles (lumens per square foot), for these tasks.  30-50 foot-candles are also optimal for a lecture at a chalkboard or whiteboard and lighting the board with additional vertical surface lighting also improves board visibility. During a multimedia presentation, however, it is important to be able to dim the lights to 15 foot-candles or less.

Using sunlight to provide supplemental lighting to rooms during daylight hours is one way to reduce energy costs. Using daylight, or “daylighting”, creates optimum conditions for learning and should be used wherever possible in classrooms, administrative offices, gymnasiums, and meeting rooms. Daylighting sensors can be used to balance artificial light and create optimum lighting conditions.

Soft, uniform, electric lighting should supplement daylighting wherever necessary to create a comfortable learning environment.  As stated previously, LED recessed troffers are ideal for lighting a room uniformly. Replacing T12 fluorescent lamps with T8 and T5 lamps with electronic ballasts can also reduce energy consumption by 35%. Gymnasiums, in particular, benefit from T5 and T8 fluorescent lamps because of their quick startup times and low heat output. If you wish to convert to LED technology, LED high bay fixtures and LED HID retrofit lamps are great, energy-efficient choices for a gymnasium as well. Investing in ENERGY STAR LED exit signs will also significantly reduce energy costs, with LED exit signs lasting 25 times longer than conventional exit signs. LED bulbs also out-perform incandescent bulbs in scoreboards and will not need replacing for years to come.

In combination with occupancy sensors and timers, lighting retrofit savings-per-classroom can double. Sensors and dimmers are equally appropriate for other school settings, such as hallways, bathrooms, storage areas, libraries, and faculty offices. Occupancy sensors in particular can reduce lighting use in these lesser-used areas dramatically.

Though operating budgets in school systems are tight, school facilities typically operate for 50 years or more. Therefore, school systems benefit from a long-term perspective and should take life-cycle costs associated with Total Cost of Ownership into account. Though some upgrades are costly up-front, payback for many upgrades occurs within a few years with a high return on investment. Additionally, a variety of rebate programs directed specifically at school systems help reduce upfront costs. If you are curious where your school system could save money, sign up for a FREE Lighting Assessment with Bulbs.com. A member of our Energy Services team can assess your current lighting system and identify products and rebates to help you save.

What is Total Cost of Ownership?

by Nicole Michaud 5 October, 2015 04:19

**An earlier version of this post included inaccurate information regarding Total Cost of Ownership and has since been corrected**

When deciding which light bulb to purchase, the cost of the bulb can be a major factor in your decision. But the cheapest bulb on the shelf might not always be the least expensive option in the long run. The truth is that the bulb you buy will determine your cost in the long term. Some bulbs cost more to use, operate, and maintain than others. These costs, all together, are known as your total cost of ownership. Total cost of ownership (TCO) is a financial estimate intended to help consumers and business owners determine the direct and indirect costs of a product. In terms of lighting, the cost of ownership takes into account the upfront cost of the product, the hours used, kWh rate, and the rated life of the light bulb.

Top Lighting Picks for Summer

by Elizabeth Karpinski 10 July, 2015 06:23

With July 4th behind us, it’s officially summer and time to think about your outdoor lighting needs. Here are some of our favorite products to light the night!

Bug Lights

Anytime you’re outside in the summer, there’s one thing that’s sure to ruin it: bugs. The problem tends to be worse at night because traditional lights attract them.

Most people are so used to seeing bugs on their outdoor lights they’ve never wondered why, or how to stop them. Insects see light differently than people do, and they’re most attracted to shorter wavelengths—light at the far end of the spectrum, close to ultraviolet light. So all too often, the most attractive light in the area will be the manmade outdoor light around your deck, porch or patio.

Bug lights use filtered yellow glass to minimize the short spectrum light—so they don’t attract insects. If you haven’t yet, this summer is the time to switch.
