This Old House on how to use them in your home application.

1. THEY SAVE ENERGY

Yes, you’ve heard it a million times, but it’s true – LED is changing the future of lighting around the world. Residential LEDs — especially ENERGY STAR rated products — use at least 75% less energy, and last 25 times longer, than standard incandescent lights. They are also used in developing countries with no access to electricity to help people study, complete tasks and increase their own safety.

2. THEY ARE GREAT FOR COMMERCIAL USE AND RESIDENCES ALIKE

LED technology is advancing so rapidly that there is hardly an application not suited for it.  Because of their highly efficient and directional nature, LEDs are ideal for many industrial uses. You have most certainly seen them used in in street and roadway lights, parking garages, parks and stadiums, refrigerated case lighting, modular lighting, and task lighting.

When you are ready to mow the lawn, you may have to pull your mower’s starter a few times before it turns over. In the event of a power outage, of course, you really don’t want to put up with such issues with your generator. Typically, whole-house generators will activate automatically when the power goes out, regulated by an automatic transfer switch. If yours is thus equipped, but doesn’t come on when needed, you are in need of repairs. If you’ve had them done before, though, and are still struggling with this issue, a generator replacement is worth considering.

Your whole-house generator burns fuel in order to power your home in the event of a power outage. If it is burning through more and more fuel during its operation, though, running your generator may simply cost more than it is worth to keep your electricity flowing when the power goes out. Replacing your system with a more efficient model may be advisable.

You need to test your generator and have it inspected regularly to ensure that it will be there for you when you need it most. If problems keep popping up upon such inspections and tests, it may no longer be cost effective to continue repairing your existing system. A replacement generator could offer you greater reliability as well as reduced repair costs.

A common concern for those involved in home renovations or purchasing a new home is, “What is the state of the electrical system in the walls”. Some homes may not have had construction or renovations done since the original – this means the original wiring is still in place. Having original wiring in place can be concerning, especially if it is aluminum wiring. This type of wiring is commonly found in older homes and can be very dangerous. Read on to find out what you need to know about aluminum wiring and the dangers associated with it.

In the 1950’s to 1970’s, many homes were being outfitted with aluminum wiring. The reason for this was because the prices of copper (material normally used for electrical wires) had increased and the use of aluminum would undercut the high costs. Aluminum is also much more conductive than copper and was used in larger industrial/commercial electrical lines like power grids and airplanes.

Despite the reduced cost and increased conductivity, aluminum wiring has many potential issues. Aluminum wiring is much softer than standard copper wiring. This means that it is vulnerable to being broken, cut, and damaged which can leave live electrical wires exposed. Another issue is that when aluminum rusts, it is not as conductive as copper. Copper that rusts can remain conductive and continue its flow of power. However with aluminum wiring, rust in wiring will impede the flow of electricity and can cause a number of other issues. Aluminum also expands and contracts when it becomes hot. This constant flux in size will result in the wires loosening themselves and connections become loose. For all of the above listed reasons, aluminum is prone to overheating and electrical fires.

If you are unsure if there is aluminum wiring in your home, we have listed a number of warning signs that can indicate a hidden problem
