Planning Conservation Along With Your Wind/Solar Installation
-----------------
The goal of most homeowners is to install a wind/solar hybrid electric system to provide electricity and lighting for the residence. One of the best ways to do this is to start with the lighting of a residence and install efficient bulbs. Most of you will think I'm talking about CFL (compact florescent). But no, I have started using LED bulbs in my residence and those that are new Wind/Solar projects. Most of you have barely begun to hear about LED technology, LED is for (light emmitting diode) and it is the most efficient and low cost way to provide lighting, BY A MILE.
LED bulbs can quickly pay for themselves through energy savings, even though they cost more. Today's LED bulbs below, use less than ONE THIRD of the energy of CFL (compact fluorescent) bulbs and last up to 30,000 hours. Between the long life of the bulbs and the savings on electricity the LED is money well spent. Below I will show you the numbers and on this page you can review and purchase the different bulbs that we recommend.
By replacing the existing incandescent lightbulbs with LEDs, a homeowner can reserve this power for other uses. Even with the expense of buying new LEDs it's substantially more cost-effective than staying with incandescent or compact florescent bulbs.
LEDs, Lumens & Performance
----------------------
According to the U.S. Department of Energy, comparison of efficiency PER WATT:
Incandescent Lamp - 12 to 15 lumens per watt of electricity
CFL (compact fluorescent) > 50 lumens per watt of electricity
High-Brightness LEDs - 30 to 35 lumens per watt of electricity
LED Takes less Lumens for same Amount of Useable light. LEDs may be able to provide enough light on the task, even though the total lumens are less than comparable incandescent or fluorescent sources. You see, LEDs emit light in a less diffuse pattern than conventional light sources. Standard incandescent bulbs and fluorescent lamps emit light in all directions, and much of the light output is absorbed inside the fixture or escapes in an unintended direction. |
