New Lightbulbs: What’s the Difference?
Traditional incandescent bulbs use a lot of energy to produce light and are no longer manufactured.
- 90% of the energy is given off as heat
- That lost energy is money we are throwing away
Newer energy-saving lightbulbs provide the choices in colors and light levels you’ve come to expect. The new lights are also much more efficient — so they save you money. Energy Efficient Lighting Saves Money
What Are My Lighting Choices?
You have many choices in energy-efficient lighting. The most popular light bulbs available are halogen incandescents, compact fluorescent lamps (CFLs), and light-emitting diodes (LEDs). Although they can initially cost more than traditional incandescent bulbs, during their lifetime they save you money, because they use less energy. You can find these in most hardware and home improvement stores as well as at FSC Lighting.
Controls such as timers and photocells save electricity by turning lights off when not in use. Dimmers save electricity when used to lower light levels. Be sure to select products that are compatible with the energy-efficient bulbs you want to use.
If you have outdoor lighting that is left on for a long time, using CFLs or LEDs in these fixtures will save a lot of energy. Most bare spiral CFLs can be used in enclosed fixtures that protect them from the weather. CFLs and LEDs are available as some of the best outdoor flood lights. These models have been tested to withstand the rain and snow so they can be used in exposed fixtures. Also look for ENERGY STAR-qualified fixtures that are designed for outdoor use and come with features like automatic daylight shut-off and motion sensors.
Energy Efficient Lighting Saves Money – Halogen incandescents have a capsule inside that holds gas around a filament to increase bulb efficiency. They are available in a wide range of shapes and colors, and they can be used with dimmers. Halogen incandescent bulbs meet the federal minimum energy efficiency standard, but there are now many more efficient options to meet your lighting needs.
Compact fluorescent lamps (CFLs) are simply curly versions of the long tube fluorescent lights you may already have in a kitchen or garage. Because they use less electricity than traditional incandescents, typical CFLs can pay for themselves in less than nine months, and then start saving you money each month. An ENERGY STAR-qualified CFL uses about one-fourth the energy and lasts ten times longer than a comparable traditional incandescent bulb that puts out the same amount of light. A typical CFL can pay for itself in energy savings in less than 9 months and continue to save you money each month. A CFL uses about one-third the energy of a halogen incandescent.
CFL bulbs are available in a range of light colors, including warm (white to yellow) tones that were not as available when first introduced. Some are encased in a cover to further diffuse the light and provide a similar shape to the bulbs you are replacing. If you are looking for a dimmable bulb, check the package to make sure you purchase a CFL with that feature.
Fluorescent bulbs contain a small amount of mercury, and they should always be recycled at the end of their lifespan. Many retailers recycle CFLs for free. See EPA’s website for more information. Energy Efficient Lighting Saves Money
Light emitting diodes (LEDs) are a type of solid-state lighting — semiconductors that convert electricity into light. Although once known mainly for indicator and traffic lights, LEDs in white light, general illumination applications are one of today’s most energy-efficient and rapidly-developing technologies. ENERGY STAR-qualified LEDs use only 20%–25% of the energy and last 15 to 25 times longer than the traditional incandescent bulbs they replace. LEDs use 25%–30% of the energy and last 8 to 25 times longer than halogen incandescents.
LED bulbs are currently available in many products such as replacements for 40W, 60W, and 75W traditional incandescents, reflector bulbs often used in recessed fixtures, and small track lights, desk lamps, kitchen undercabinet lighting, and outdoor area lights. They come in a variety of colors, and some are dimmable or offer convenient features such as daylight and motion sensors. LEDs work well indoors and outdoors because of their durability and performance in cold environments. Look for LED products such as pathway lights, step lights, and porch lights for outdoor use. You can also find solar-powered outdoor lighting. Energy Efficient Lighting Saves Money
While LEDs are more expensive, they still save money because they last a long time and have very low energy use. As with other electronics, prices are expected to come down as more products enter the market.

Installing Energy- 5 Reasons to use Energy Efficient Lighting.
It’s no secret the cost of electrical energy continues to rise and will inevitably continue to do so in the future. At the same time, the demand for electricity continues to increase, taxing our existing electrical infrastructure to the margins of their design limits. We need more power, but in order to get it, we need new transmission and distribution infrastructure – but that’s just the beginning.
Efficiencies need to improve. Smart grid and microgrid strategies need to be deployed, and energy storage needs to be maximized. The list goes on and on. The problem is all of these propositions require a large amount of capital, which seems to be in short supply these days. Therefore, the quickest and least expensive way to generate more electricity is to not consume it in the first place. One way to use less energy is to install newer and more energy-efficient lamps, luminaires, and controls. Even lighting systems that were deployed just five years ago could benefit from newer lighting technologies and/or better control strategies.
The U.S. Energy Information Administration (EIA) estimates that about 461 billion kWh of electricity were used for lighting by the residential and commercial sectors in 2011. This was equal to about 17% of the total electricity consumed by both of these sectors and about 12% of total U.S. electricity consumption. Residential lighting consumption was about 186 billion kWh – or 13% of all residential electricity consumption. The commercial sector, which includes commercial and institutional buildings and public street/highway lighting, consumed about 275 billion kWh for lighting – or 21% of commercial sector electricity consumption in 2011. Installing Energy- 5 Reasons to use Energy Efficient Lighting. Energy Efficient Lighting Saves Money
The good news is lighting has become more efficient over the last decade and continues to evolve. Not only have lamps and luminaires become more efficient, but so have lighting control systems. Installing new luminaires and lamps – or retrofitting existing luminaires and lamps – is standard practice for the electrical industry. However, installing lighting controls to save energy has sent many electrical contractors and technicians back into training mode.
1. Energy Savings – Lamp/luminaire and lighting control strategies are driven by the need to save energy and by the adoption of energy codes like the International Energy Conservation Code (IECC), ASHRAE/IESNA 90.1, or state standards like California’s Title 24. As lamp efficacies improve, energy codes are driving down the number of watts per square foot used to light any give space within a building. Add in effective lighting controls, and you can drive down energy consumption even further. On the voluntary side, the Leadership in Energy and Environmental Design (LEED) certification program, developed by the U.S. Green Building Council (USGBC), has had a profound impact on driving energy-efficient lighting design as well. Energy Efficient Lighting Saves Money
There are other benefits for installing a well-engineered lighting system. Although the following benefits may appear to be less quantifiable, in reality, they are no less important than saving energy. First is the effect that a lighting system has on improving the productivity, recruitment, and retention of the customer’s employees. The second is green and zero net energy branding opportunities. A 2015 research study, found an average 3.2% increase in productivity from lighting improvements. The same study also revealed that a 1% increase in productivity equates to 100% reduction in energy costs. Energy Efficient Lighting Saves Money
2. Large choice of lighting technology – Lamp and luminaire choice is usually driven by customer request in consultation with an architect, lighting designer, or both to meet occupancy requirements. However, in some cases, the electrical contractor may become the specifier of the lamps and luminaires to reduce costs for the customer (value-engineering). Electrical contractors involved in design/build projects have greater influence over lighting selection. Because most design/build electrical contractors are not lighting designers, learning something about basic lighting design benefits everyone involved.
Just like the lighting designer, the electrical contractor needs to understand the customer’s lighting requirements. In the case of value-engineering or design/build scenarios, realize that the customer may be relying on your expertise when it comes to lamp/luminaire selection, layout, and control. Some basic questions to ask the customer include: What is the major task(s) that will be performed in the space (e.g., task lighting)? What surfaces or objects need to be lit (e.g., focal lighting)? What types of fenestrations will the space contain (e.g., daylighting)? Is any lamp/luminaire going to be used as an architectural or decorative feature (e.g., decorative lighting)? What is the mood of the space, or what are the navigation requirements within the space (e.g., ambient lighting)? In some designs, energy savings and increased productivity may be gained by separating task lighting from ambient lighting and using innovative control strategies.
3. Lighting has become understandable – The proper selection of the lamp and luminaire begins with understanding something about the qualities of a light source, which are determined by the method used to produce the light. Light sources range from incandescent and halogen to fluorescent and HID to light-emitting diodes (LEDs). Lamps are rated in lumen output, watts, and lumens per watt or efficacy. Lumen output is the total light output of the lamp. This does not include fixture lumens only lamp lumens. (It’s important to understand the difference when evaluating LED lamps and luminaires.) Efficacy is the measure of how efficient one light source is when compared to another. The more lumen output per watt of power consumed, the more efficacious the lamp is. When purchasing lamps, think lumens, not watts. Energy Efficient Lighting Saves Money
4. Quality – The quality of light is also a measure of its color accuracy and the color of the light itself. Color accuracy is a measure of how well the light source can render the colors of an object. This is known as the color rendering index (CRI), which is measured on a scale of 0 (very poor rendering) to 100 (perfect rendering). The color of the light the lamp produces (whether the light appears warm, neutral, or cool) is a function of its color temperature. The lower the color temperature, the warmer (more red) the lamp appears; the higher the color temperature, the whiter or cooler the light source appears (more blue). This is known as the correlated color temperature (CCT), as shown in the Figure. Energy Efficient Lighting Saves Money
Other areas of concern when selecting a lamp are its operating temperature range, lamp life, lumen maintenance (how much light output diminishes over the life of the lamp), directionality, dimmability, starting time, and life-cycle costs. All lamp qualities need to be understood to provide the customer with the desired end result. This implies that you, as the electrical contractor, understand how all lamps generate their light and what their operational characteristics are. Control strategies will be predicated on the operational characteristics of the lamp and occupancy requirements. Energy Efficient Lighting Saves Money
The goal is to have a better understanding of the nature of light – not necessarily to become a lighting designer. However, if you are providing design/build services or value-engineering a lighting system, understanding some basics of lighting design will help a great deal. Many lighting and lighting control manufacturers provide basic online training with regard to understanding the nature of light, lamp characteristics, luminaire selection, and the correct switching or dimming control devices and topologies. Many lighting manufacturers also offer webinars and training courses, some of which are free. Staying on top of the latest training resources in the lighting arena will go a long way toward maximizing your next energy-efficient installation.
The annual savings to upgrade to energy efficient lighting
Energy Savings – Assuming you have a 2500 square foot home, with a total of 25 – 60W incandescent bulbs (lamps, fans and bath fixtures), 15 – 65W BR40 spot lights (can lights), and 4 – 4? 40W t40 fluorescent bulbs (closets and laundry).
The total out of pocket cost to replace these bulbs with LED lighting would be approximately $485.00, including professional installation. Installing Energy-Efficient Indoor Lighting Systems
The total annual savings realized based on .11c/kwh would come to $240.00 annually in energy usage, up-front, the payback seems to be 2 years! However, you must consider the longevity and useful life of the asset, LED bulbs last on average 14.7 years compared to 2.1 years for standard incandescent. Essentially, you will have to replace incandescent bulbs 7 times. The bottom line is that over the life of the LED product (14 to 15 years), you will save over $3200.00 in energy usage and bulb replacement.
This analysis is done for a 2500 square foot home, do the math, many homes in Plano Texas are much larger. Your savings could be enormous.
