Everyone wants to save money.  With the economy, still slow and unemployment high, family and business budgets are tight.  Thus, we’re all looking for ways to lower our bills, and there aren’t many bills more devastating to budgets than the electric bill.  Not to mention those bills during a brutal Texas summer.

At the same time, people are finally beginning to understand that the damage we do to our environment is harmful in the long run, and are trying to find a way to reduce our impact on the planet.  A lot of the time it seems like we must choose between saving money and helping the earth.  That is simply not the case when we’re talking about options for lighting your home or business.  The employees of my Plano electrical service tell you that you can actually do both at the same time, and that it‘s as simple as changing a light bulb!

Light bulb shopping has changed a lot in the last ten years.  Our choices are no longer limited to the incandescent (and sometimes halogen) bulbs we all grew up with.  Today fluorescent CFL lights are available in almost every store, and LED lights are starting to become more widely available as well. These bulbs use far less energy to create the same amount of light, which ultimately means less energy you have to pay for.  The savings can be seen with a single bulb.

For example, if you replace just one 60-watt incandescent bulb you use four hours each day with a 12-watt LED equivalent, you’ll wind up saving almost $10 a year on average! These bulbs can save you money and hassle in ways you might not think of at first.  For instance, LED and CFL bulbs produce very little heat when compared to an incandescent bulb which means that they don’t attract insects, and that your air conditioner doesn’t have another heat source in your house to cool down.

There are electrical benefits to having cooler bulbs too: less heat being generated by light bulbs means that there’s less heat stress being placed on the sockets and fixtures they’re attached to.  Less stress on the fixtures means that they have a much longer life, and that you’re saving money you’d otherwise have to spend on repairing or replacing them.

All these choices beg the question of which type of bulb is better.  From an electrician’s view, they’re both superior to the old kind of bulbs.  Personally, I think LED lights are superior to fluorescent CFL lights right now.  The technology that makes CFL bulbs work is still primitive.  Think of what cell phones looked like in the 1980‘s compared to today; right now, the CFL bulbs you can buy are the fluorescent bulb version of those old brick phones. LED lights have very distinct advantages:

These reasons are why I generally recommend LED bulbs; they’re more earth-friendly, easy to dispose of, use less energy than even CFL bulbs, and last a very long time.  They can be more expensive than other bulbs, but you’ll save enough money on your power bills in the long run to come out well ahead!

Saving on energy costs and outfitting your home or office environment with new lamps and light fixtures should be at the top of your home improvement project list.  Not only do new light sources deliver a superb quality of light, they are the key components in decorative and energy-efficient lighting design.

It is an exciting time in the lighting industry.  New products are being developed every day, and LED (light emitting diode) and SSL (solid-state lighting)*  lamps and light fixtures are at the core of future illumination.

What’s more, the integration of LEDs into building and electronic communication systems is bringing everything together and enabling total control with the ease of a smart phone!

Here are some guidelines to help you answer those questions and invest wisely toward one of the greatest home improvement projects of the decade:

WHAT YOUR LIGHTING DESIGN CAN AND SHOULD DO FOR YOU…

In addition to providing optimum levels of brightness, good lighting design must also…

•Eliminate glare

•Increase comfort

•Provide continuity

•Deliver good color rendering

•Allow for adjustability

•Instantaneously make you ”feel good” with an inviting luminous appeal

Because LED lamps require so little energy to provide a great deal of illumination, the energy consumed by the bulb will not be your main concern; your main concern will be getting the desired level of brightness and light appearance.

*NOTE:  LEDs, also referred to as SSL, provide the most energy-efficient and durable illumination because they are composed of “solid state” semiconductor light emitting diodes.

1.    Familiarize yourself with labels on new bulb cartons.

Brightness (in lumens)

Estimated Yearly Cost (depends on rates and use, $)

Lamp Life (based on 3 hrs/day use, rated in years)

Light Appearance (CCT)  (warm-cool, rated in degrees Kelvin (K))

Energy Used (in watts)

Color Rendering (CRI) (measured on a scale of 0-100)

BRIGHTNESS

Brightness levels are measured in lumens to give the amount of total light created by the light source.  Beyond the lumen count, “useable” light and brightness levels are also affected by fixture housings, lenses, filters and shades.  There are clear standards set to measure the lumen output of each LED chip.  ↓

LIGHT APPEARANCE  

Light appearance or correlated color temperature (CCT) helps determine the quality of illumination.  Designated on the Kelvin (K) scale, CCT for decorative interior spaces should be in the warm white (2700-3000K) range.  Sometimes lighting in the neutral white (3500-4000K) is preferred for certain areas, such as bathrooms and kitchens.

LAMP LIFE AND THE LED

Lamp life refers to how long a light source will last once it is installed and used on a daily basis in a typical application. Lamp life ratings, based on estimates from testing,  convey the time that half the bulbs in a sampling have burnt out or dimmed below fifty percent.

COLOR RENDERING AND THE LED

The color rendering index (CRI) measures the ability of a light source to bring out the true colors in décor, objects and surfaces.  Based on a scale of zero (no color rendering) to 100 (perfect color rendering),  a minimum of 80 CRI is acceptable for interior lighting applications.  A CRI of 90+ is even better.

However, because the standard CRI measurement does not always yield true results for some LED light sources, a new standard measure of color quality is in the works:  The Color Quality Scale (CQS) may soon replace CRI for a truer account of color rendering provided by the LED light source.-www.ledlightingexplained.com, Philips Solid-State Lighting, 2010

2.    Match light fixture to light source to ensure peak performance.

LEDs small size, low-temperature emissions, and focused uni-directional beam patterns make them perfect light sources for undercabinet lighting, track lighting and pendant fixtures.

LED general and flood lighting replacement bulbs are composed of clusters of diodes to provide broader beams of light.  General service LED bulbs that are multi-directional with 360-degree angle capacity are doing an excellent job of replicating the desired illumination of old incandescent bulbs. These LED  lamps include A19, PAR, BR and candelabra light sources that are providing more light with the added benefit of tremendous energy-saving, maintenance-free illumination.

Due to their long life and durability, LEDs are excellent in hard to reach places like foyer, attic and cathedral ceiling fixtures.

*Check for compatibility with all new light sources to make sure lamps, light fixtures, dimmers and automated controls are a suitable match.

3.    Compare “apples to apples”; diodes to diodes to ensure top quality.

 Many factors contribute to the quality of the LED light bulb.   Advancements in diode technology and mass production of LED light sources are bringing costs down to make these bulbs more affordable.  However, be wary of “cheaper” LED light sources.

•COB (chip on board), the diode itself is composed of a chip that largely determines  the quality of the bulb.

Prior to being marketed in appliances, fixtures or light bulbs, LEDs are sorted into bins according to their light output (lumen output) and color temperature.  Due to the process of “binning,” LED chips vary in their quality—especially in relation to their lumen output and color, so it is important to purchase LED light bulbs and LED light fixtures from a reputable dealer.

LEDs chosen from bins with higher lumen output are of better quality.  Color temperature is determined by matching up each LED according to a chromatic line grid for a specific color temperature.   LEDs chosen from larger bins contain more color variation , so they deliver an inferior quality of light.

•LPW (lumen per watt), this measurement helps to determine energy-efficiency and efficacy

•IC (integrated circuit) drivers, the quality of the LED lamp is also dependent on the type of driver installed.  LED bulbs contain “drivers” that can fail just like the ballast of a CFL (compact fluorescent). Better driver components make for a higher quality LED light source.

ENERGY STAR-ratings ensure that the LED has met stringent testing procedures.  ENERGY STAR-rated lamps clearly identify characteristics on LED light sources to guarantee that they consistently and reliably meet the desired brightness (lumens), energy-efficiency (lumens per watt), color temperature (CCT), color rendering (CRI), and dimmability requirements.

New ENERGY STAR Regulations include:

•Consistency Control:  More standardized testing methods to improve consistency.

•Dimmability Ratings:  A lamp is either dimmable or not dimmable.  If a lamp claims to be dimmable, testing is required and it must dim down to at least 20 percent.  If it is not dimmable, it must say so on the package.

•Greater Energy Conservation:  Efficiency requirements have increased for specific lamp wattages and types.

NOTE:  The Environmental Protection Agency (EPA), along with ENERGY STAR offers rebate programs as an added incentive to help you spring into action and upgrade with LED.  Check out rebate programs in your area or contact an American Lighting Association (ALA)-affiliated showroom for more details.

For any home that depends on natural gas power for heating, cooking, or other tasks, a risk exists of exposure to carbon monoxide. Most modern gas appliances and pipes are built to high safety standards and should present little danger to a household. However, it is wise for any home with a gas line to set up carbon monoxide detectors as a precaution.

You don’t have to tell us twice just how important a fully functioning electrical system is to the success of your commercial building or your business. When something goes wrong on your property, you need everything back up and running as fast as possible to avoid a serious business interruption and loss of profits.

Damage to your electrical system can certainly have a negative impact on your bottom line. So when you do find yourself in need of electrical repairs, who do you call?

Electrical failures are almost always a serious issue. It can leave your commercial space or business without power for hours, or even in danger of an electrical fire. When trouble brews, you don’t want to be stuck with a handyman or amateur electrician who requires you to wait until 9 A.M. on a Monday when the problem happens on a Friday evening. Ensure that you can trust your work to professional electricians with 24-hour availability, for your own peace of mind and convenience.

Of course, there’s nothing stopping a new company from hiring an electrician with years of experience. However, typically a newer company won’t be able to deliver you with the same confident level of quality as one that has decades of experience, such as our staff. It’s also far easier to put your trust in professional electricians who have shown that they deserve the respect of the community and their long-term clients.

This is perhaps the most important point—when you have a commercial space with electrical needs, you want a team on your side that is experienced with this kind of work. Commercial settings have specific electrical demands that aren’t seen in most residential properties. Technicians who can handle the wiring and electrical needs for a whole commercial building will have the necessary skill set to take care of whatever your repair needs are.
