If you’re like us, you are proud of the artwork you’ve chosen to adorn the walls of your home or business. A framed movie poster, an original oil painting, or even a stylish wall hanging all serve to bring color, and life to a room. Make sure that the images that have been so carefully selected are seen in their full splendor with the right lighting.

One studied alternating current (AC), and the other, direct current (DC). And yet, the world would not be where it is today without their contributions to science and electricity. In light of Nikola Tesla’s birthday on July 10, Mr. Electric is taking a look at the electric Tesla vs. Edison feud.

The main focus for Tesla was alternating current: an electric charge that periodically reverses its direction and is delivered to customers through a transformer. It travels at a much higher voltage than direct current and is more effective because of its ability to travel greater distances while maintaining a constant voltage.

Edison focused his research of electricity on direct current. A key difference between alternating current and direct current is that direct current only flows one way. The voltage of direct current is also constant but it is better when the electricity produced has to travel in short distances.

Edison was working on a system to generate direct current. When he could not get it to perform correctly he hired Tesla, an engineer and graduate of The Polytechnic Institute, who studied electromagnetism, promising him $100,000 if he could correct the problems Edison was having with his research and invention. Tesla corrected the problems but was not given the money. Tesla resigned and Edison spent the rest of his career trying to discredit Tesla’s research and work with electricity.

Today, nearly every home and business in the world is powered using Tesla’s alternating current. The ability of alternating current to travel over long distances and efficiently power everyday home and business electrical equipment eventually overtook Edison’s research on direct current. Edison did not lose out completely, as most battery-powered devices, fuel cells and light emitting diodes use direct current. As the push for alternative energy sources is on the rise, many manufacturers are looking at how batteries and electricity can change the way we look at fuel and the way goods are produced. Whether the electricity being used is AC or DC, Tesla helped us get where we are today.

relatively high ceilings. Drive by any industrial park, warehouse, or factory, and walk inside and what you will see is a high bay light.

But walk into any factory or warehouse and you will see different styles and options, wattage’s and configurations. Traditional high bay fixtures that were once common place were Mercury Vapor, which were then replaced with High Pressure Sodium and Metal Halide bulbs. As new technologies were introduced, and old technologies became more common, the old HID bulbs were replaced with Induction and Fluorescent light sources. And more recently with the more wide spread approval and popularity of LED, we started to see conversions from these older technologies to the latest energy saving LED High Bays.

A High Bay Fixture, depending on the light source, can take on many forms and shapes. If you consider a Metal Halide or High Pressure Sodium fixture, they typically consist of a large heat sink block at the top of the fixture that typically houses the fixtures ballast. Below is an aluminum or acrylic dome and at the top of the dome is the HID bulb. These bulbs typically come in two wattage’s, 400 and 1000. 400 Watt Fixtures tend to be installed in ceiling heights no higher than 30 feet, 1000 watt fixtures are typically 40 feet or higher. Interestingly enough, spacing of lights is similar to the height they are located off the floor. A fixture installed at 20 feet from the floor is installed in a 20X20 pattern, 30 feet in a 30X30 pattern, 40 feet in a 40X40 pattern. Of the 3 type of HID bulbs, Metal Halide tends to be the best option. High Pressure Sodium Bulbs are very low on the temperature color and have the warehouse aisles have the ability to focus the light where it is needed. A light designed for a warehouse aisle is a lot different than a light designed for a gymnasium or a factory floor. In these spaces, a light that can flood the area evenly is important, in a warehouse aisle, a light that can light up the face of the shelves and the floor below is important. And when selecting energy efficient options, its just as important to understand the technology and what it is capable of doing. Adding controls to a T5 fluorescent fixture is a good idea only if the ballast is designed to handle that requirement and not lower the life expectancy of the bulbs. Motions sensors and daylight controls that dim the light output based on occupants and the amount of daylight available in the space. Technologies such as metal halide and high pressure sodium are not a good choice as these technologies are not good at dimming or turn on or off quickly. Fluorescent can dim, but you need special ballasts for them. So knowing what you want to do and may want to do is important at time of purchase, because not having the proper equipment or options could mean a costly lighting warehouses, factories, gyms and readily available through the utility companies, and mass adoption means the technology of LED had matured to the point where the questions and disbelief of past years have gone away.

If you are like many homeowners, your home is a constant work in progress. Your desire to make your home uniquely yours is a constant endeavor. Unfortunately, there are many areas within your home you may overlook in an effort to make your home look appealing. In particular, some homeowners constantly overlook their old light fixtures.

Whether you live in an older home or a home you’ve recently purchased, new light fixtures can transform the look of your home and increase safety. Like other aspects of your home that you use on a regular basis, your light fixtures can easily become worn and dated. Unfortunately, as a component of a major system in your home, damaged light fixtures can be a hazard.

Your home is your oasis, so there is no reason for you to constantly endure poor lighting. With new fixtures, you can take advantage of some of the latest designs that improve your ability to see throughout your home. Additionally, changing your light fixtures will help you realize the following benefits:

These days, advances in technology are helping homeowners reduce the cost of their utility bills. From LED lighting technology to incandescent lights, new lights increase lighting in homes while decreasing homeowners’ costs. This is especially helpful for homeowners who are concerned about their impact on the environment; reduced energy consumption helps reduce the negative impact on the environment.
