Light Bulbs

Did you know roughly 1/4 of your electricity bill is used specifically for lighting? With recent changes in lighting technology, we now have the ability to control the costs of our electricity consumption more effectively. Choosing the right lightbulbs for your home or business may be confusing with all the different options we have today, so we’ve listed the three most common types in hopes to shed some light on the issue. *pun very intended

Incandescent Bulbs
Incandescent bulbs, the oldest and most common bulbs on the market, are relatively inefficient compared to other bulbs. They work by connecting an electric current that travels through a wire filament, heating up the filament until it illuminates. Unfortunately, up to 90% of the actual energy it consumes produces heat. The cost of each bulb is the lowest compared to other bulb types, but their lifespan is also the shortest, as they only last up to 2 years (based off 3 hours of use / day). With the passing of the Energy Independence and Security Act of 2007, manufacturers are working to produce more efficient incandescent bulbs that produce up to 25% less energy.

Compact Fluorescent Lamps (CFLs)
Distinctive by their bold designs, Compact Fluorescent Lamps (CFLs) are the most energy and cost effective bulb type on the market today. An electric current is driven through a tube containing argon, and a small amount of mercury vapor that triggers the actual illumination. CFLs use up to 75% less energy than traditional incandescent bulbs, cutting overall electricity costs significantly without producing excess heat. Their lifespan can be pushed up to 9 years, and technically pay for themselves after just 9 months of use, costing less than half as incandesces bulbs for the same amount of light.

Note: research has shown that CFL’s work best when left on for long periods of time, but lose efficiency when turned on and off regularly. Because of this, it may be best not to use CFL light bulbs in areas like closets where the lights are usually just flipped on then off.

Light Emitting Diodes (LED)
Making an appearance in electronics starting in 1962, Light-Emitting Diodes (LEDs), are rapidly taking the lighting industry by storm with its highly effective technology. By connecting a diode to an electrical current, electrodes are triggered within the diode, forcing them to release photons, which we see as light. The up-front costs of LEDs are higher compared to other bulb-types, but ultimately they last up to 25% longer than traditional incandescent bulbs. Manufacturing has increased drastically in recent years, and companies are expected to offer more affordability in the near future. By reducing energy consumption by up to 80%, LEDs pave a direct path to lower electricity bills.

Almost everything nowadays operates on electricity. The modern conveniences that drive our world depend on electricity. Without a constant supply, our world grinds to a halt, as massive blackouts have proven in the past. Electricity has two forms in modern electronics: AC and DC.

AC [alternating current], is most frequently used in devices that require high amounts of power to operate.
DC [direct current], is more commonly found in devices requiring smaller amounts of power to operate.

Understanding AC vs. DC
Direct Current
DC was the original electricity that was created by Thomas Edison. This style of electricity sends a current in only a single direction, from a power source and to the power source again in a loop. Today, DC is used to power electronics that require batteries. Any device in your home that uses batteries uses DC current. Interesting to note, if your battery is plugged in to the power supply to recharge, it transforms AC current into DC.

Direct current is also used in manufacturing situations where electricity is generated on site for personal use. Factories and mills that require vast amounts of energy often create their own DC current to power their machinery. Most commonly, DC is found in steel mills, aluminum production, and is used to power mass transportation in large urban centers in the form of electric streetcars.

Alternating Current
AC power is easier to generate, which is why we use it as our standard electricity nowadays. The alternating current design allows energy to flow in both directions, making electricity easier to create and use in society. Regardless of where the current is moving, it is always moving in both directions at once. This results in current being present at every point in the power grid at every time as long as the connection to the generation unit is intact. The power that comes from the power plants, down the lines to our homes, is always AC in nature, thanks to the way our modern power grid is set up.

The power grid operates by creating AC current and sending it down the power lines. This current can be at whatever intensity the power company chooses.

Frequently, the electricity coming from these lines is far too powerful to be used in our homes. The transformers that we see on power poles transform the electricity from its high-powered state into something that our homes can use. Without the transformers, we wouldn’t be able to use the power that our society depends on.

Regardless of the style that we use in our devices and our homes, electricity plays an important role in society. Without both AC and DC electricity, we wouldn’t have those things that make modern life as comfortable as it is.

Storm Safety

Thunderstorms pose a safety hazard in several ways. Lightning is the most dangerous part of a thunderstorm, and it kills more people than hurricanes and tornadoes combined. Thunderstorms produce heavy rain, which can cause flash flooding. The strong winds from a thunderstorm can also cause widespread damage. Each of these components requires specific precautions to minimize their danger.

A thunderstorm typically has a diameter of 15 miles and lasts for 30 minutes, which is much smaller than a hurricane or winter storm. The National Weather Service places specific criteria on a severe thunderstorm. These include thunderstorms that produce hail with a diameter of at least ¾ inch, wind gusts of at least 58 mph or a tornado. Severe thunderstorms comprise about 10 percent of all thunderstorms. And we know how quickly Central Florida weather can become dangerous.

Lightning
Lightning from a thunderstorm can strike as far as 10 miles away in from any rain. This generally means that you are at risk from lightning. Lightning travels much faster than sound, which allows you to estimate your distance from the lightning. You can do this by measuring the number of seconds between the lightning and thunder. Divide this result by five to obtain the distance to the lightning in miles.
The NWS recommends that you stay indoors for 30 minutes after the last clap of thunder when you hear thunder less than 30 seconds after the lightning. This rule is known as the 30/30 lightning safety rule.

Emergency Shelter
You may need to take emergency shelter in a thunderstorm if you don’t have time to get back to your main residence before the thunderstorm hits. A shelter should generally be a sturdy structure that is closed on the top. It should also have some type of wiring or plumbing through the structure to ground it from the lightning. A vehicle with a hard top is better than no shelter at all.

Avoid taking emergency shelter in structures that are vulnerable to high winds, such as a mobile home. Outdoors shelters such as sheds, pavilions and golf’s typically will not protect you from flying debris and lightning. Avoid and report downed power lin
es. Bring pets under shelter to protect them during hailstorms.

Indoor Precautions
You must also take additional precautions once you are safely indoors. Unplug any electrical appliances that you don’t need immediately, since lightning can severely damage electrical appliances when they are plugged in. Refrain from activities that involve running water, such as taking a bath or shower. Running water can provide a conduit for lightning. Draw the blinds to protect yourself from broken windows.

Once the storm clears and you're safe it is time to take account of the any damage that might be done. Let Marbec Enterprises help you get back on your feet.

Industrial and Residential Wiring

Whether you’re doing industrial wiring or residential wiring for electricity, you’ve got a complex task ahead of you. Needless to say, industrial wiring is essentially a much more complex form of residential wiring. Let an electrician at Marbec Enterprises take care of it for you. We will simply provide you with a very basic overview of what you need to understand with regard to residential wiring and industrial wiring.
It will be up to you to look up your local building and electrical codes for your home or office space. Also, check your local laws to see if you are even permitted to do your own amateur wiring before you proceed. Above all things, approach any wiring project with this knowledge at the forefront of your mind: “electricity can be deadly.” Put your safety ahead of all other concerns. Marbec Enterprises is trained in all aspects of electrical work.

Basics of Doing Residential Wiring
Red wires and black wires are usually “hot”. This means that there is a current (amps) flowing from the circuit breaker to the electrical box or the appliance in question.
The white wires usually are “returns”. This means that they allow current (amps) to flow back to the circuit breaker after the electricity has passed through the load or appliance in question.
White wires should not be connected together with ground wires, with the exception being back at the circuit panel bus bar. If you fail to observe this rule, then every single time the load is energized (such as turning on an appliance), electricity will flow through the ground wire and the return wire simultaneously. This is very dangerous.

A ground wire is usually bare and attaches to an appliance’s frame. Under normal circumstances, current should not be passing through it. Only when there is a short circuit should electricity pass through the ground wire; this happens so that the circuit breaker will kill the flow of current to the site or appliance.

Basics of Doing Industrial Wiring
Smart industrial wiring is based on 3-phase electrical power. 3-phase electric allows less workload to be placed on each wire involved while at once allowing them to work together to give you maximum results. With 3-phase electric, the wires are smaller and the motor is smaller than a typical single-phase motor. These factors allow greater efficiency and longer lasting motors and wires.

There are four types of 3-phase electrical power:
Common 3 Wire
Common 4 Wire
3 Wire with Grounded Hot Leg
Special 4 Wire

No matter which type of 3-phase electrical power you choose to use, you’ll need a voltage meter in order to determine the actual voltages that are available to you. The type does not determine this.
Industrial wiring typically runs through metal conduits, armored cable, or a raceway. These enclosures are the safety ground–never the neutral wire.

The Marbec Electrical team of highly trained commercial electrical contractors has provided top quality electrical installations for large commercial building projects in Florida for over 10 years. We are trained in all aspects of commercial electrical work and offer extensive expertise and professional service to our clients.

How To Stay Safe When Dealing With Electrical Appliances

It is the rare person who does not deal with electrical appliances today. Most people watch television, turn the oven on to cook food, or simply pop frozen foods into the microwave. With electricity pouring through virtually every home, everyone should be aware of the following electrical safety precautions:
1. Never use electrical devices that have damaged or frayed wires.
The thick wires that connect an electrical device to the wall for energy are designed to safely transfer electricity from the socket to the device. When those wires tear apart, fray, or otherwise become damaged, they can allow the flow of electricity to escape the wire. This can lead to a shock of you grab the wire in that area, but it can also lead to an electrical fire. Safety precautions require you to throw these appliances out if you cannot replace the wire.

2. Play it safe with water in close vicinity to electrical devices.
When water comes in contact with an electrical outlet or electrical device plugged into the wall, it can become live with electricity and present a danger to humans. If you have a flood in your home, do not step into the water if it is covering electrical outlets. Do not place electrical devices where they can fall into a sink or bathtub full of water.

3. Watch the placement of cords leading to electrical devices.
All electrical devices have cords, and it is common to run longer cords along the wall in order to place them where you want them. The problem is you can create a tripping hazard if you run cords along doorways or across floors in heavy traffic areas of your home. Carefully place cords where they are safe for everyone in your home.

4. If you are going to change parts on or repair an electrical device, you have to disconnect it from the outlet or otherwise shut off electrical flow to the device.
Never do work on or repair an electrical device while it is live with electricity. In most cases this just means unplugging the device before you open it up to make repairs, but when doing home improvement projects it could mean shutting off electricity from the breaker box. If you don’t know how to do this, then do not attempt the repairs on your own.

All of these electrical safety precautions should be remembered by adults working with electrical appliances. If you know someone who isn’t aware of any precaution on this list, send them here to learn. It could save a life!

When in doubt, call an electrician from Marbec Enterprises and have them take the worry out!

Light Switch Or Outlet Not Functioning Correctly

When a light switch or electrical outlet doesn’t function correctly, a professional electrician from Marbec Enterprises can trace this back to a variety of causes. First, it’s possible this non-functioning device was never connected to the wiring in your building. Secondly, the circuit affected by a switch or outlet may not be completed because of another component. For example: A switch may control an outlet which is unoccupied by a lamp or any other electrical device. Also, an outlet may be connected to a switch which is in the off position. A third cause might be related to a defective breaker, or a breaker which was tripped or turned off, but never switched back on. However, a fourth possibility may relate to a much larger problem.

Sometimes, a switch or outlet fails when it is damaged by arcing. If the arcing was caused by a connection to aluminum wiring, great potential hazards exist. If your home or building was constructed or renovated before 1972, or during the late sixties, it may contain aluminum wiring. Aluminum wiring was used legally during those years, but outlawed for installation in new homes, commercial buildings, remodels and renovations after it was identifie

d with conditions which could lead to electrical fires.

Although aluminum wiring itself is generally no more hazardous than copper, its splices and connections with other metals present a real hazard because they can become corroded and begin arcing. Because arcing in these connections can lead to fire within surrounding materials, aluminum wire was discontinued. However, many homes still contain aluminum wiring, and research conducted by the Consumer Product Safety Commission (CPSC) reveals that buildings with aluminum wiring pose a fire risk which is 55 times greater than the risks with similar structures wired with copper. So, if you discover an electrical outlet or switch which doesn’t appear to be functioning correctly, it’s possible this outlet or switch was damaged by a connection with aluminum wiring. If you have safety questions about this type of problem, or any electrical concerns regarding your residence or commercial building, please contact an electrician at Marbec Enterprises. Our licensed electricians are trained and equipped, and they can repair any type of electrical problem

Short for “light emitting diode” and introduced commercially in the early 1960’s, the first LEDs produced low levels of red light, and were first used as indicator lights on electronic equipment. As their name suggests, LEDs are diodes, and will operate on both AC and DC electric current. In the mid-seventies, the first digital watches featured LED displays, and in the following decades, LED technology expanded into many applications as LEDs producing most of the light spectrum were developed, from infrared to short wave ultraviolet.

Most notable has been the development of LEDs producing extremely bright “white” light. Although these “white LEDs” first produced very cold bluish white light, their output has become more sophisticated, and LEDs are now available which produce “neutral white” as well as “warm white” light. The latter light color is very pleasing, and quite similar in color temperature to light produced by halogen lamps. Another term for LED lighting is “solid state lighting,” as opposed to “hollow state lighting” which describes nearly every other type of lamp or light bulb. LEDs have seven distinct advantages over halogen lamps, and ten advantages over fluorescent lamps. Smaller in size, quicker in response time, and cooler in operation, LEDs last 100,000 hours or more – longer than both halogen and fluorescent lamps. They are more efficient in their consumption of electrical energy than either halogen or fluorescent lighting, and they are safer than other lighting because LEDs can operate on much lower voltages. Also, because they have no delicate glass envelope or fine wire filaments, they are much more resistant to shock and vibration than halogen and fluorescent lamps. Because of their low voltage operation and resistance to impact and vibration, solid state lighting is rapidly replacing all other forms of RV, truck, marine, aerospace, and automotive lighting.

Very recently, solid state lighting is also appearing in homes and offices. And this is where its additional advantages over fluorescent lamps really shine. First, when operated from a DC power supply, solid state lighting doesn’t flicker like fluorescent lighting, which lends to a much more comfortable environment for individuals sensitive to flickering light. LEDs designed for visible spectrum illumination produce no harmful UV emissions, making them safer for our eyes and for artwork which can fade from exposure to ultraviolet light. Most importantly, LEDs contain none of the hazardous mercury vapor present in all fluorescent lamps, including CFLs (compact fluorescent lamps). Because of the mercury vapor they all contain, fluorescent lamps of all kinds represent a serious and potentially dangerous hazard in our homes, schools, hospitals, public spaces, and offices. They also represent a serious ongoing disaster as we dump literally tons of mercury from discarded fluorescent lamps into our environment every year. So, as prices for LEDs continue to drop, we should all hope to see solid state lighting replace all forms of environmentally hazardous fluorescent lighting. If you are interested in a mercury free home or workspace, please contact Marbec Enterprises.
