A bit of mathematics at the end of the week. The

The first table shows three different installations. The old one is equipped with T8 fluorescent lamps that are at the end of their lifetime and dirty. That is why the luminous flux is so low for the 60W tube. In this situation, the need for a replacement is present. The choice is between a fluorescent tube, a LED tube or a completely new installation with controls. Controls reduce the average power consumption to 1/3 and less of the original load. We can estimate the new fixtures will consume 12W only when connected to controls that detect presence in the hall and reduce the lighting level in areas that are not in use. Each light point will be replaced. It is (often) possible to reduce the number of fixtures with a new installation. The example is concentrating on a one-by-one replacement to make it easier to understand.

The table above shows the sum of all costs for running and maintaining the installation each year and in total. The Retrofit Solution reaches an ROI after 2 years already. The New Installation with controls is going to turn back the high investment after 10 years. Both LED solutions do better than the conventional one, save energy and CO2 emissions. Let’s go green with LED light sources!

One of the least understood terms in LED Lighting is efficacy, or in simpler terms, how efficient is the light. It is typically measure in lumens/watt. Today, efficacy is becoming more and more important because efficacy varies greatly from product to product. What the consumer needs to be wary of is that you should not be mislead into thinking that just because you are switching from HID or fluorescent to LED that you are getting the best savings available. You also need to look at how efficient the LED product is to maximize the savings.

Here is an example of how this works. Let’s look at a two USA Made competitors LED Retrofit Kit compared to our 4th generation LED kit. All three units are designed to replace 400W HID

From this table, you can see that all products produce over 13,000 lumens, with the MyLEDLightingGuide product producing the most at 14,528 total lumens. It also consumes the least amount of energy of the three units at 105 watts, compared to 130 and 135 watts. For the record, all three products come with a 10 year warranty on the head and a 5 year warranty on the driver. MyLEDLightingGuide also offers a 10 year warranty on the driver as an optional upgrade.

But what does this all mean in terms of saving you $’s. Let’s take a typical scenario. Let’s say these retrofits are installed in MyLEDLightingGuide 105W retrofit kit. Multiply this number over 10 years and by the number of fixtures you have to replace, and this is real dollars. And let’s not forget the MyLEDLightingGuide retrofit kit is also much brighter than the competitors products.

So efficacy is important. It saves you money. But a well designed kit will also produce more light. Just think, without efficacy we wouldn’t have as great of savings, nor would we have more light production from the same amount of power.

Efficacy is huge in the world of lighting, and it is only going to get better year by year. Technology improves, lights improve, and thus; efficacy improves. In 10 years, lights that will be made are probably going to be 5x improved then they are today. And since they are already super efficient today, just imagine that times 5. Now that is efficacy!

The living room seems a little dim, you think. Here’s the DIY solution you cook up: you head over to the hardware store, buy a brighter bulb, screw it into the nearest lamp and bask in the incandescent glow. Easy, right?Not exactly. Using a lightbulb with higher-than-recommended wattage for a specific fixture is known as overlamping. This seemingly innocent practice is actually surprisingly dangerous, and is one of the leading causes of house fires in the United States — right up there with candles, smoking and cooking mishaps.

Overlamping is one of the most commonly overlooked mistakes a homeowner can make, and it can be deadly. A 2011 electrical fire that killed 11 people in Brisbane — the according to home improvement blogger Taryn Williford. When you place an incandescent bulb with wattage that’s too high in the socket of a lamp that cannot provide the required electrical output, the ensuing heat and intensity of the bulb can scorch or melt the socket and the insulation of the lamp's wiring.  

Now you have prime conditions for arc fault. An arc fault occurs when a spark jumps through the air between exposed wires. This sounds dangerous, yes? It is — in fact, the National Fire Protection Agency and the National Association of State Fire Marshals electrical power. A CFL often has a tubular shape atop the familiar screw-bottom.

An LED (light-emitting diode) light is directional, rather than radiant. This allows the LED to use much less energy than an incandescent light or even a CFL. LEDs can also directly replace incandescent bulbs in some cases.

CFLs use a much lower wattage than incandescent bulbs and create far less heat, making overlamping situations far less likely. LEDs also use much less electricity and even remain cool to the touch. The risks of overlamping are negligible.

There are drawbacks to any lighting solution. Incandescent (even halogen) lights are energy inefficient. CFLs are made from materials that are terrible for the environment. LEDs burn out at a quicker rate. The right light for you is the light that makes you most comfortable in your home — and that’s a decision you need to make.

Perhaps you've always wondered what's in the mysterious metal box on the basement wall. It's a circuit breaker box, and without it your whole home electric system would be unsafe, leaving you in danger.

Circuit box repairs or upgrades require an expert, but you don't need to be a master electrician to understand the basics of how it functions. The most common problem is a tripped circuit, and you can usually reset it yourself.

What's in the Box?

The circuit box is frequently found in the basement, although it could also be in a garage, closet, utility room or even outside. All the electricity coming into your house flows through the box.

If you open the metal door, you see a bank of switches. Each one corresponds roughly to a room in the house, while certain outlets for major appliances like the washer or furnace probably have their own switch. They should be labeled.

There also may be a main disconnect breaker, usually at the top of the box, which allows you to cut off power to the entire house. In many newer homes the main disconnect may be outside near the electric meter. Some homes do not even have one. This is useful if you are doing electrical work in your house, or in the circuit box itself. The switch should be labeled “main” or something similar.

How It Works

Why do you need a circuit box? When an electrical device malfunctions, such as the motor in your freezer overheating, wires can get crossed, creating a huge spike in electric charge. That puts you at risk of overloading your electrical system, and unchecked overloads can cause lead excess heat stress on wires, or worse.

Fortunately, your circuit breakers are on the job. There is an electromagnet or bimetallic strip inside each breaker. If the current moving through the circuit gets too high the device flips a switch, disconnecting the circuit. No more electricity can flow to the part of your home where the problem is, so the danger is averted.

So if the power goes off in one part of your house but still works in the rest, a tripped circuit breaker is the most likely culprit. The switches in your electrical panel should be labeled; if not you can still tell which one got tripped, because it will be flipped part way toward the off position. Some switches also show red when they've been tripped.

How Do I Fix It?

All you have to do to restore power is flip the switch all the way to the off position, then back to on. If flipping the circuit back on doesn't solve the problem, it might be something more serious. In that case, it's time to call a licensed electrician.

Some newer circuit breakers have advanced features, such as the ability to detect when a person makes contact with a live wire and automatically cut off the current, potentially preventing injury or death by electrocution.

If you live in an older home you may still have a fuse box. It operates on the same principle as a circuit box, with one major difference -- the wire inside the fuse actually burns up if too much current passes through it, so if the fuse blows, you need to replace it. Most fuse-style panel are maxed out, so if you have one it would be a good idea to consult your electrician and see if it’s time to consider a replacement.
