LED Light Bulbs – Their Time Has Come

Just as we all have made the switch to compact fluorescent bulbs (I hope!), along come LED light bulbs, which are now the most energy-efficient, eco-friendly, and long-lasting.  And they are affordable!

LED bulbs last about 25 times longer than incandescent bulbs and 3 times longer than CFLs. LED bulbs and diodes have a life time operational expectation of about 30,000 hours, or 11 years of continuous operation or 22 years of 50%.  Imagine not changing a light bulb but once every 20 years or more!

What’s more, you can cut your electric bill by 80 – 90%.  With a LED bulb, at least 60% of the electrical energy is converted to light.  Conventional incandescent bulbs convert 20% or less into light and the rest is lost as heat, which is why they are so hot to touch.

There are also more advantages.   CFL bulbs take a few minutes to brighten.  LEDs are bright immediately.  The color of the LED lights has improved immensely too – you can choose either whiter or warmer bulbs. And they are durable and dimmable.

Unlike CFLs, which contain toxic mercury, LED lights are free of toxic chemicals with zero UV emissions.

I just bought the CREE home LED bulb from Home Depot.  It looks almost exactly like a conventional bulb and only cost $10. CFL bulbs were a great interim energy-saving bulb, but now it’s time to make the switch to the eco-friendly LED light bulb.  You will pollute less and save money – you and the earth have everything to gain!

Save Money, Save The Earth!

I am participating in the Mass Save blogger program working to further connect my readers to topics of energy efficiency.   Mass Save®, an initiative sponsored by Massachusetts’ gas and electric utilities and energy efficiency service providers, “provides a wide range of services, incentives, training and information promoting energy efficiency to residents and businesses.” Mass Save works closely with the Massachusetts Department of Energy Resources.

One of the easiest ways to save energy and money is to use CFL (compact fluorescent) or LED light bulbs instead of incandescent ones.  Incandescent bulbs have been phased out, so I imagine most of you have already made the switch.

Energy efficient lighting has come a long way and now has bulbs for most lighting fixtures.  There are standard bath bar bulbs, LED reflector light used for dimmable ceiling fan bulbs, track and recessed lighting, chandelier bulbs, spot lights, and all sizes of standard bulbs.  One of the newest bulbs is the Philips L Prize LED with a life span of 20 years; 1 10-watt is the equivalent of 30 60-watts!

Though CFLs are whiter, brighter and better than they used to be, they are a temporary solution to energy-efficient lighting while engineers fine tune the development of LEDs.   This simple comparison chart below from eartheasy.com illustrates the cost and energy savings of the new, energy-efficient lighting.

 

Energy Savings over 50,000 hours, assuming 25 bulbs per household:

                                                       LED                                    CFL                                    Incandescent

Total Cost for 25 bulbs            $2143.75                        $2243.75                                    $8812.50

Savings to Household              $6668.75                        $6568.75                                        $0

By switching from

incandescents

National Grid is holding a fun, interactive “celebration this summer to celebrate ENERGY STAR’s 20th Anniversary. They are inviting summer camps and programs in Massachusetts and Rhode Island to participate in the program by creating energy efficiency-themed “gifts” (in the form of projects) to celebrate the spirit of ENERGY STAR.  Visit http://www.nationalgridcelebrates.com/ for more information.

COMPACT FLUORESCENT LIGHT BULBS

Did you know that switching from the standard incandescent light bulbs to compact fluorescent ones is one of the easiest things you can do to save energy, save money, and lower your carbon footprint?  Fluorescent bulbs last ten to fifteen times longer than incandescent ones, which only last a few months and obviously produce more trash for the landfills.  CFLs use only one quarter to one third the energy as incandescent bulbs to produce the same amount of light.  If every American household switched to CFLs, it would cut power demand for lighting in half.

Compact fluorescent bulbs (CFL) cost more than a standard bulb, but as always there is a hidden cost to being cheap.  According to the US Department of Energy, only 10 percent of the electricity an incandescent light consumes is actually used to generate light.  The other 90% becomes wasted heat.  In addition, one 18-watt CFL bulb will replace ten 75-watt incandescents and save $45.00 in electricity costs in its lifetime. My electricity bill went down around $20 per month once I switched to CFLs!

CFLs come in a variety of sizes and shapes and can now be used with dimmers.  Most hardware stores, Lowes, Home Depot, and even grocery stores carry them.  One downside, CFLs contain a miniscule amount of mercury and must be disposed of properly when they burnout.  You can recycle them at the dump or at some retailers like Whole Foods.

Make the switch and feel good about saving money and energy.  And don’t forget to turn off your lights when not in use!
