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!

Have you ever seen the outlets that have buttons in the center? Or perhaps ones that have a little light that you take to indicate that it is working properly? Then you’ve seen a GFCI outlet.

GFCI stands for ground-fault circuit interrupter; this is indicative of the outlet’s ability to stop the current in the circuit if there is an imbalance between the hot side of the plug and the neutral side.

There are many different circumstances in which having GFCI outlets installed could be beneficial. In fact, there are several circumstances in which building codes require the installation of them by a certified electrician.

Say, for instance, that you’re using a hair dryer and for some reason it isn’t functioning properly. The electricity may want to try and take the shortest way to the ground versus continuing to flow through the circuit. This is one way an electrocution can happen. If the current starts shifting towards the person holding the appliance, a GFCI outlet will register that and trigger in less than one-thirtieth of a second, stopping the continuation of the electric current.

GFCI outlets should be installed by an electrician in places that could experience moisture such as around the kitchen counters, the bathroom, and for outdoor outlets. As we mentioned previously, some building codes require GFCI but any homeowner should consider installing GFCI outlets throughout the house to help prevent over two-thirds of electrocutions that happen.
