If you’re ever a contestant on Jeopardy and you’re asked what a GFCI is, you can respond by saying, “What is a ground fault circuit interrupter.” But knowing what GFCI stands for doesn’t mean you understand what it is. You’re not alone—the average homeowner is unaware of what a ground fault circuit interrupter does, but when your house’s ground fault is compromised, it can put the entire property, and your family, in danger.

A ground fault is an electrical path between a power source and a grounded surface. While all electrical devices and appliances are “grounded” to ensure they can be safely operated, devices can still lose their grounding and divert electrical currents to the nearest channel that provides a path to the ground: you. That’s why you need ground fault circuit interrupters in your home.

You’ve probably seen GFCI and never given them a second thought. They’re a common safety feature found on your electrical outlets that can be identified as two small buttons located in between the two sockets, the GFCI’s function is to constantly monitor the power current flowing through a circuit. At the first sign of a discrepancy between the current flowing into the outlet and the return current, it intervenes by shutting off the power to the outlet.

Making sure that you have a good HVAC system is a top priority for most homeowners throughout the country. The most common type of air conditioning system is the traditional, central AC unit, which used a series of ducts in order to push cool air throughout your home.

There is another type of AC system that can benefit almost any homeowner though: the ductless mini-split air conditioner. When it comes to installing a new system or replacing the air conditioner you already have, there are many reasons to consider a ductless system, which we’ve highlighted below.

To understand the benefits of a ductless cooling system, its first important to understand what it is. As the name suggests, this type of system does not require ductwork in order to heat or cool your home. Instead, a ductless system uses individual, wall-mounted units which circulate air in each different zone or area of your home.

Ductless systems can be quickly installed by a professional air conditioning technician, as they only require a few refrigerant lines and electrical wires that connect them to a central outdoor condensing unit. It’s actually the system’s refrigerant that removes the heat from your home and carries it to the outdoor unit, where it is exhausted outside.

Annie is a recent UNC-Chapel Hill graduate who majored in English with a minor in creative writing. Annie wrote this post during the interview process and we loved it so much, and learned a little bit about art in the process, we could not wait to post it to the blog. We hope you like Annie’s first post as much as we do, and can’t wait for her to “enlighten” us even more in the coming months.

In paintings, the depiction of light can create tangible shape, intricate texture and vibrant color. Great painters like Rembrandt, Caravaggio and Manet crafted careers out of working with light, while having very few lighting options for inspiration. Here are a few examples of their work, and how each painter might go about achieving the same schemes with modern lighting:

The employment of lighting in this Manet painting differs greatly from Rembrandt and Caravaggio. Instead of valuing shadow to illuminate dimension, Manet uses full frontal lighting to emphasize color – bright reds, whites and yellows.

We all know or at least heard that converting from Metal Halide (High Intensity Discharge) to LED will save you money.

But how much? Are there any other reasons or difference you should know about?

In this article, we break down all the factors that you should be aware of before making a decision to convert from Metal Halide to LED. Here are the 9 reasons we think LED wins over Metal Halide.

Let’s take a look at the information on a typical 400 watt metal halide bulb. While specifications may vary, a visit to a popular online website that sells Metal Halide bulbs shows that a brand new bulb has the following specifications:

We have just as many customers wanting to convert to LED because of maintenance savings as they do for energy savings. Think about what we discussed, over the life of the LED retrofit kit, a customer would have to do 5-6 Metal Halide replacements. The higher the installation height, the higher the cost of replacement. And if you have a facility loaded with lights, this becomes a significant budget amount every year that you must take into consideration. Now, we know that reduced maintenance time on lights does not translate into dollars saved because it is highly unlikely that people will lose their jobs over the fact there is much less work to do. However, these people will have time to now work on things that matter, like fixing the machines that make the company money instead on replacing lights that cost the company money.

When you take a measurement of light with a light meter, it reads lumens. And this measurement of all the lights that contribute to the light at that location creates a measurement called foot candles. But let’s think about that light that is being measured. Metal Halide creates all sorts of light, in all spectrum’s, visible or otherwise. This includes UV and IR spectrum’s, visible to the measuring device but not visible to the human eye. LED, on the other hand, does not produce UV and IR. Therefore, its readings using the same light meter is only picking up visible spectrum’s.

So there is a fun little test you can do. Have 2 light sources, LED and Metal Halide. And first ask, which one is brighter? And if the right LED source was selected, they should say LED. And then use a light meter, and the light meter may say the Metal Halide area is producing more foot candles. And so now you know part of the reason, but wait, there’s 2 other pieces of information you need to know.
