So when customers ask us how many ‘Watts” do I need to replace an existing light source, we always convert them to lumens.

•  Pay special attention to the lumens per watt of a fixture. IT DOES MATTER. A LED product at 135 lumens/watt will consume far less energy than a LED product producing 97 lumens/watt. Not all LED solutions are the same. (remember, always buy on the lumens you need, never on the watts you think you need.).

•  To calculate lumens per watt, take the total number of lumens a product produces and divide it by the watts it consumes.

For indoor fixtures, figure on:

utility company. You can check if a product is DLC Qualified on the DesignLights Consortium website. DLC has rebates for Commercial LED Lighting and Industrial LED Lighting

•  Rebates with DLC Premium should be higher than rebates with DLC Standard. Your utility company is typically who provides the rebates and sets the rebate amounts.  Check their website.

•  All UL Listed or ETL Listed.

•  Replacing the light parts of an existing fixture with the a Retrofit unit will not void the UL/ETL Listing of the fixture. However, the exception to this rule are explosion proof rated fixtures (ie. Class I Div 2). Never retrofit a certified explosion proof fixture. UL1598C does not cover these types of retrofits.

•  ETL Listing is the same as UL Listing. They perform the same test, and the certification is the same. The only difference is that the company who performs the test.

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.

Imagine how relaxing it would be to soak away the day’s stresses or invite friends over for a fun party featuring your own hot tub. Having a hot tub or sauna in your backyard or patio area is a dream of many. These provide a lot of fun as well as stress relief and are more affordable than you may think. However, the idea of installing a hot tub is something you may not be ready to tackle yourself. Even if you are looking to save money, you may find that calling a Burbank electrical service, such as The Electric Connection, is actually the best option. Consider the following before you think about installing a hot tub yourself.

Safety

Even if you are a skilled at home improvement projects, installing a hot tub can be a dangerous activity. This is because installing a hot tub combines water and electricity. You do not want to take the risk of injury to yourself or others by making a mistake in the installation. A licensed electrician in Burbank has the background to make certain he or she is not injured and the electrician should have insurance in case there is an issue.

Equipment Care

In addition to your personal safety, you should also keep in mind properly caring for the equipment during the installation process. In many cases, you will void the warranty on a hot tub or sauna if you do not install it properly. So for this reason, search the internet for electrician Burbank and allow a professional to take care of this job for you.

If you are considering the installation of a hot tub, sauna or backyard water feature, find a Burbank electrician by visiting The Electric Connection’s website at ElectricConnection.com  or calling us and talking to a customer service specialist today.

In many parts of the country, like Los Angeles where I do electrical work, electric vehicles (EVs) are being delivered to anxiously waiting customers. Deliveries are also starting in other West Coast cities as well as cities along the Eastern Seaboard. In the center of the country, not so much. In many cases, these areas will start receiving deliveries towards the end of 2011.

Let’s say electric car deliveries have already started in your area and you own of these new-fangled vehicles — a Nissan Leaf or Chevy Volt. How do you recharge the battery? In my last post, I talked about the simple and inexpensive option, Level 1 charging. This is using a charging cord that comes as standard equipment with your electric vehicle, similar to the one your cell phone comes with. You’ll need an electrician to make sure that you’ve got the right kind of outlet in your garage or carport (GFI outlet on a dedicated circuit). Your electrician will also need to check whether your electrical panel needs upgrading for sufficient capacity. Once it’s a go, plug your charging cord into the outlet and wait … a long time. For the Chevy Volt, 10 hours, and the Nissan Leaf, 20 hours — empty to full.

Even though Level 1 charging is slow, drivers who have short commutes may be satisfied with it because, if they work it right, they won’t start at empty. They’ll have charge left in their batteries and will simply top off at night.

Here’s how it can work. The range of the Nissan Leaf is about 100 miles. Americans drive an average of 33 miles a day. Drivers who drive the average 33 miles will use only one-third of the battery in a day. If they religiously plug in when arriving home, they will be able to top off at night in about seven hours and leave with a full charge in the morning.

In addition, the pressure to be fully charged when leaving home will ease as chargers are increasingly installed in public places. Chargers are already available in Los Angeles train stations, the main airport (L.A.X.), the L.A. Convention Center, and other public places. One can easily find the network of existing public chargers on-line. In addition, malls will begin installing chargers as an inducement for shoppers and workplaces as an employment benefit. In time, you’ll be able to recharge your battery while you shop or work. But we’re not there yet.

For hybrids, like the Chevy Volt, the issue of leaving home fully charged is less pressing. The Chevy Volt can drive for about 35 miles on a fully-charged battery. Once the battery hits empty, it, like other hybrids, the Volt turns to burning gas in a conventional internal combustion engine. This isn’t good for gas usage, but on the other hand, the driver may suffer less from “range anxiety.”

While you may be able to make Level 1 charging work, you also have the option of faster charging by installing a special Level 2 charger in your garage or carport. More on Level 2 Charging in later posts or find out more by clicking here.
