Automated lighting controls come in various forms.  How they are each implemented into your home or office and how they work with one another will determine the effectiveness of your energy efficient lighting system.  Many new forms of automated lighting controls aim to take advantage of information shared by new utility sponsored programs called the "smart grid".  

 In essence, smart grid technology takes a network of data from power plant production to regional and final end user consumption, and reports who is using how much energy, where and when.  With this type of information power plant operations can distribute power accordingly without increasing peak production.  From the end user's standpoint, our homes and offices, we can access this same information to determine when electricity will cost the most and respond accordingly.

 But more effectively, companies have taken the initiative to develop automated
demand response lighting controls that eliminate the need for human response.  At the same time they enable the user to easily override the controls and set their own preferences.  While demand response lighting controls can be used by residential consumers to dim lights in specific areas during peak demand, they are most effective in commercial office applications.

To illustrate the potential savings of switching your traditional incandescent light bulbs to LED light bulbs or other energy efficient light sources, Energy Efficient Lighting Supply has created the Annual Energy Savings Calculator.  All you have to do is type in the watt rating of your current light bulb, the watt rating of a comparable LED light bulb, and how long the light will be on each day.  The calculator does the rest and immediately reports the amount saved per year in energy costs.

On a recent trip to buy light bulbs, you may have noticed a label on light bulb
packaging that looks strikingly similar to the nutrition facts label on items at
the grocery store.  This new label, regulated by the Federal Trade Commission,
is designed to help consumers choose the correct light bulb based on criteria
pertaining to lighting quality and energy consumption.  For years, consumers
have purchased light bulbs based on the wattage or power consumption
and the capacity of the fixtures the bulb would be installed in.  This traditional
rule of thumb is actually backwards, and only applicable to incandescent light

In an effort to produce more energy efficient and long lasting products, the lighting industry has produced different light sources that install in your traditional fixtures, but, because of varying technical attributes, produce different levels of light output that do not directly correlate to wattage.  After all, the purpose of an energy efficient light bulb is to produce the same quality of light while having a
lower wattage (power consumption).  This how-to guide will introduce the facts
on the lighting label and how to make sense of them.

 1.  Brightness- Perhaps the most important piece of information on
the lighting facts label is the measured amount of light emitted by a light
source.  It is measured in lumens, which can be further understood with
knowledge of the unit of foot-candles.  However, as a rule of thumb for
consumers, a 60 watt incandescent light bulb produces about 890 lumens.  Using this basis, energy efficient lighting decisions can be made according to light production not power consumption.

 2.  Estimated yearly energy cost- This fact is very self-explanatory as stated on the label.  It can be useful when comparing two labels side-by-side because the cost for each will be associated with the same amount of daily usage for the year. This number varies with usage per day and your utility rates.  As utility rates increase your annual savings compared to a less efficient light bulb will increase as well.

 3.  Life- Pertains to the average life of the product based on 3 hour per day usage.  The light bulb can last longer or shorter based on daily use. It is important to consider this number when comparing estimated yearly energy costs among light bulbs.  On an economic basis, the replacement cost associated with the life of the light bulb will impact the cost effectiveness of
your purchase more than the yearly energy costs associated with using the light bulb.  

 4.   Light Appearance- The label portrays light appearance on a kelvin scale of warm to cool.  This refers to the color temperature of all visible light.  The warmer the light the more yellow or orange it appears, a cooler light bulb will appear white and almost have a tint of blue in it.  This aspect of the label has no association with efficiency of the light bulb but can
be very useful to a consumer.  In general, warm lights are desired for interior use in living spaces as ambient lighting.  Cooler light appearance is desired for outdoor use or in kitchens or workspaces where high color temperature comparable to natural daylight is desired. 

  5.  Energy Use- A Watt is the unit for power and refers to the energy consumption of a light source.  The lower the number the more energy efficient the light bulb is.  As said before, this number has no universal indication of how bright a light source will be.

  6.  Contains Mercury- This note represents that improper disposal of the light bulb can be an environmental hazard.  A lot of people don’t understand that even though compact fluorescent lights (CFLs) are considered environmentally friendly because they use less energy, they still contain mercury.  For proper disposal procedures visit as indicated on the label.
