Every commercial space, whether it’s a hotel, restaurant, office, department store, small shop, school, or hospital, can benefit from switching to LED lighting. LEDs are energy-efficient alternatives to halogen, and Universal LED Bulb Finder to search by bulb type, or browse our site to see hundreds of lighting options.

There are many LED recessed lighting options for existing can lights, eyeball lights, or other recessed commercial applications. Traditionally, recessed fixtures contain either a PAR halogen bulb or a BR incandescent bulb. These bulbs are available in several different sizes, and each type has its own set of features. BR bulbs typically have wide flood beam patterns and allow for more of a gradual fade of light. LED replacement PAR and BR bulbs have those same features but with increased energy efficiency and longer life spans. Complete LED fixture replacements, such as downlights, are also an option.

When it comes to commercial lighting, one of the most popular fixtures is the fluorescent panel light with T8 tubes. These panels offer little in the way of quality lighting. Hot spots are visible even through their textured lenses, and the light that they emit has a yellow-green hue. CRI), which is the key to showing the true colors of objects and surroundings. They emit crisp, clear illumination with no visible hotspots, and you won’t have to worry about replacing them for a very long time.

It’s no secret that a well-lit sign will stand out more than one that is poorly lit. LED sign modules are available in many different intensities and colors to illuminate signs, light boxes, marquees, and channel letters. Because LED bulbs can last up to 25 times longer than incandescent or halogen alternatives or approximately five times longer than fluorescent tube lights, the need for replacements is few and far between.

Central forced air heating is by far the most popular kind of Zone heating, also called zone control heating, is a system of dampers installed in the ductwork of your home. The dampers are basically large valves that can open and shut to direct air flow. A damper is installed at each room junction, effectively splitting the house into a number of isolated zones. A thermostat is installed in each room with a damper, allowing that room total control over the air flow into it.

Zone heating is often installed to remedy the two problems mentioned above. Normal central air heating is inaccurate in which rooms it heats, so zone heating isolates each room to allow precise control over their climates. Central air heating causes a lot of uneven hot and cold spots, due to its reliance on a single thermostat. Zone heating compensates for this by installing many thermostats, ensuring that each room can be set to the comfort level of whoever occupies it.

By solving these two issues, zone heating saves energy and makes the rooms in your home more comfortable to be in.

Hydroelectric power is a technology which produces electricity via hydropower, or the energy released by moving water, such as for instance water moving through the course of a river or falling downhill. In the United States today, most hydroelectric power is generated by water flowing downhill, and most of this downhill flow is achieved via the construction of artificial dams. The dams are constructed so as to engender sufficient water outflow volume by way of creating a significant “head” or, that is, the difference in height between the water’s source (or crest) and the water’s outflow.

A significant enough “head” is necessary to produce a sufficiently useful flow of energy from the hydroelectric power source. This is why dams constructed for the purpose of creating hydroelectric power are built as high as is feasible. Within these dams there are turbines which receive the force of the water’s flow, and the turning of the blades of the turbines generates the electrical current which is transferred to long-distance power lines and transformed into electricity for use in homes and offices.

In addition to the dams there are some tidal harnesses which have been constructed. These draw electrical power from the flow of the tide along a coastal area. In the United States, there is a heightened interest in creating many more small, unobtrusive tidal flow hydroelectric power generators in rivers and large streams which would be used just for generating local electricity. In Canada, there is so much electricity generated by hydroelectric facilities that they simply say “hydro” to refer to any public electricity utility, even nuclear power. Norway and Iceland also generate nearly all of their citizens’ needed electricity by way of hydroelectric power.

North America has the greatest hydroelectric power capacity. Canada is the world’s leading nation in that regard, and the United States is the world’s second leading nation.

Except in nations that have a proportionate abundance of the right natural resources (i.e. a lot of water), hydroelectric power is used to handle the supplying of electricity during high peak loads. Today’s greatest single interest in harnessing more hydroelectric power resides in the fact that it is a renewable source, or “alternative source”, of electricity, since obviously the planet will never run out of water and it doesn’t matter if the water utilized is potable or not.

The big concern about using more hydroelectric power is that it may disrupt ecosystems too much if more facilities (especially dams) are installed. A secondary concern is that water demand for hydroelectric facilities sometimes conflicts with irrigation demands.

The Greeks were using hydroelectric power to turn water-wheels for the grinding of grain over 2,000 years ago. Hydroelectric power was “rediscovered” in the 18th century in the U.S. and western Europe.

The first modern hydroelectric dam was completed in 1882 on the Fox River in Appleton, Wisconsin in the United States and could generate 12.5 kW of electrical power. It was based upon the ideas of American inventor Lester Allan Pelton, who invented a jet-free water turbine in 1880.

An important component in your main electrical service panel is commonly known as the breaker. If you’re a homeowner, surely you have visited yours a few times over the years. But what exactly is it? And what does it do? Let’s go over the importance of the breaker and what its doing for your home.

If you read our article on the home electrical system a few months back, you will know which step the service panel comes in receiving electricity for your home. The service panel is the gateway for all electricity in your home. After electricity comes through underground or overhead power lines, it goes to your electrical meter and then to the service panel. Electricity branches off from here and travels to the rest of your home. Within the panel are circuits for different areas for electricity to travel. Shutting down a circuit can cause power loss to a part of the home, maybe a room or two. But because the home is on many different circuits, power can remain active in the rest of the house.

After electricity arrives at the service panel, it travels to a circuit. The circuit is a loop in which electricity travels from one end to the other. The breaker splits up to 100 amps or more into the circuits to distribute the power. Usually each circuit in a common residential home operates at 15 amps. The breaker is designed to “trip” if it receives an excess of electricity. If a power surge occurs on the outside of the home, for example a lightning strike, the service panel will stop the flow and turn off. If a surge happens on a circuit within your home, the breaker will also shut down that loop to protect the rest of the house.

Over time if work on a service panel is not completed correctly, the circuits could blow more frequently due to overloading. Parts in the panel can become outdated, loosen, or get burned out. If a service panel is not maintained and up to code, it also poses specific risks, making your home more susceptible to fires and electrical surges.
