Most of us will not be leaders with the ability to speak and the bravery to act as Martin Luther King, Jr., but we can change the world for the better in small ways.  Even one bulb at a time…

The world of illumination is changing quickly and advancing into a new frontier with light sources that are more durable, more energy-efficient and better for the natural environment.  While we still have a choice, future lighting installations with LED (light emitting diode) lamps will provide the best light for your home or office space.

To make the best choice, there are a few lighting facts you should know.  All LEDs are not created equal, so read on to educate yourself and make a change to LED with confidence.

Learn what light sources are available and the limitations and benefits of each light source, so that you may choose the best one for each application.

•The right lighting will always help you look better, feel better and perform to the best of your ability.

•The right lighting will always be energy-efficient.

•The right lighting will always work well with the natural environment, making the most of sunlight streaming in during the day and delivering illumination in the most eco-friendly manner.

•The right lighting will last.  Choose good quality bulbs and light fixtures that are guaranteed to provide excellent illumination, equipped with fine finishes and components that are durable.

1.  KNOW YOUR BRIGHTNESS LEVELS IN LUMENS

New bulb cartons are required to prominently display the brightness level (measured in lumens (lm)).  In the past we have determined bulb brightness in terms of energy consumption in watts (W), but now we must learn to think in lumens (lm).  Here is a quick conversion chart to help get you started:

Lumens            Old Incandescent                                             LED

2600 lm————→150W——————————–→25-28 W

1600 lm———— →100W——————————–→16-20 W

1100 lm————→75W———————————-→9-13 W

800 lm————-→60W———————————-→8-12 W

450 lm————-→40W———————————-→6-9 W

2.  CHECK OUT COLOR QUALITY:   Correlated Color Temperature (CCT) and Color Rendering Index (CRI))

•CCT is measured in Kelvin’s (K) and is an important factor determining the quality of light for your specific application: Warm White or Soft White is about  2700-3500 Kelvin’s (K) and Bright White light is about 4000 K+

•CRI is measured on a scale of 0-100 and is an important measure of the degree to which your light source will show the true colors of all that is being illuminated.  Color rendering for decorative indoor lighting applications should be between 85-100.

3.  FACTOR IN DIMMING CAPABILITY

Most dimmers work by reducing the amount of electricity sent to the bulb.  But with LED the correlation between brightness and energy consumption is much different than with incandescent illumination.

Because of this difference, LEDs are not always compatible with traditional dimmer switches.  You either have to replace your switch with one that is compatible with LED or look for replacement LED bulbs that are compatible with standard incandescent dimmers.

4.  FIND SUITABLE BULB-TO-LIGHT FIXTURE MATCH-UPS

The reflector and fixture type will play a significant role in determining the light output from the light source (bulb).  Look at colored lenses and fitters, as well as shades and shielding to determine how they will help steer and direct your desired level of illumination.

When looking to replace an incandescent bulb with an LED bulb in a lighting fixture where the bulb will be totally enclosed, be sure to check that your LED is specifically made for an enclosed or recessed light fixture.  LED bulbs run cooler than others, but they do produce heat. To protect the quality of the LED chip and the performance of your LED light source, LED fixtures are specifically engineered to provide adequate heat-sinking.

5.  BEWARE OF THE LOWEST “BINNER” and COMPARE PRICE VS. QUALITY

“Binning” is the process by which LED chips are sorted.

Prior to being marketed in fixtures or light bulbs, LED chips are sorted into bins according to their light output (lumen output) and color temperature.  There are clear standards set to measure the lumen output of each LED chip.  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 and are not as bright.

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.

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.
