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 illustrates the cost and energy savings of the new, energy-efficient lighting.

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 for more information.
