How do you find out how energy efficient your ceiling fan is?

Ceiling fans can be highly energy efficient if they are used properly. Typically, when a ceiling fan is running on high it only uses 60 watts of energy this is a great deal less than a central air conditioning unit which uses 3,500 watts of energy. These fans are not just energy efficient; they can also save you a lot of money – saving you up to 40% in air conditioning costs!

Ten years ago it was difficult to work out how energy efficient the ceiling fan you wanted to purchase actually was but nowadays that information is readily available. On most fan boxes there is an information table that specifies the airflow efficiency.

Airflow is measured in cubic feet per minute (cfm). The higher the number, the more air that is moving. The rate of energy consumption is measured in watts and the quantity of energy that is consumed is measured in kilowatt-hours. The energy efficiency of the ceiling fan can be worked out by dividing the rate of air flow per unit time by the energy use per unit time.

Most of the information in the table on the fan boxes tells you the air flow cfm, the rate of electricity use in watts and the airflow efficiency (cfm/watts). However, this is usually the airflow efficiency for ceiling fans that are running at high speed. If you want to know the airflow efficiency for ceiling fans running at medium or low speed then you need to look at ceiling fans that have an Energy Star label as these will have this information on the box.

It is important to research which ceiling fan you are purchasing as this can affect the airflow efficiency.

It is recommended that ceiling fans with a blade angle of less than twelve degrees wasting energy. This is because the blade is at too low an angle to push the air and the blade will instead cut through the air. You need to purchase a fan that has blades that will push the air upwards or downwards for peak efficiency.

It is also important to think about what ceiling fan you are purchasing. For example, in a room where there is going to be a lot of papers that you don’t want blowing round, such as the study, it is best to purchase a ceiling fan with blades that have an angle of between twelve and fourteen degrees. If you are purchasing ceiling fans for a general use room you want the fan to have blades that are an angle of fourteen degrees or higher.

5 Reasons To Switch To LED Downlights

Light Emitting Diodes, also known as LED’S, offer great light quality. Because of this, more and more people across the UK are making the change to LED downlights. LED Downlight White

Why should you make the switch to LED Downlights?

There are numerous reasons why you should consider replacing your halogen downlights with LED equivalents.

  1. Energy Efficient - LED downlights are much more energy efficient than traditional light bulbs. This is as LED bulbs have a low energy consumption rate, in that they use less energy to generate light than traditional filament or energy saving halogen bulbs. Turned on, LED lighting only use on average 20% less energy than other bulbs. LED down-lights can be used with solar panels or wind power generators as they run off a twelve volt or twenty-four volt system.

  1. Long Lasting - LED lights last much longer than traditional lights. In fact, you could leave an LED bulb on continually and it can last up to eleven years! LED downlights also do not decrease in brightness over time like traditional light bulbs which show a visible decrease in brightness.

  1. VersatileDownlights can be used anywhere. They are extremely durable, and can be used for many applications. LED lights have a range of different shades of light colour including white, warm white, RGB (red, green, blue) and are colour changing.

  1. Safe – LED downlights are much safer their more conventional counterparts. They are virtually impossible to break as they have no filament. LED lights also are safer to touch because they operate at a lower temperature than traditional lights, which also reduces heat pollution.

  1. Money Saving – The final reason that you should switch to LED downlights is that they can save you money on your electricity bill. LED down-lights cost a little more to buy than traditional light bulbs but they are much cheaper in the long run. This is as the money that you spent on the lights is recouped by the decrease in the cost of your electricity bill. LED downlights also save you money in the long run because they are much longer lasting than a traditional light bulb which means that you don’t have to continually replace the bulb which would cost you money. If you use LED lighting in a shopping centre or office block the fact that they are longer lasting will also save you money on maintenance bills if you’re a business owner.

How Do LED Lights Work?

LED lighting is gaining popularity across the whole of the UK. For example, LED panels are now becoming the go-to lighting solution for businesses in a number of sectors. But how do LEDs generate light?

How LED Lights Work: The Science

Traditional incandescent light bulbs create light by passing an electrical current through a wire filament which causes the wire to heat up and emit light. This is grossly inefficient. In fact 80% of energy created by traditional bulbs is heat rather than light.

LED stands for light emitting diode. The light from an LED light bulb comes from a solid matter inside the bulb. This matter is known as a semiconductor.

The semiconductor is what lights up the bulb. The physics of this is can be a bit confusing, but is relatively simple. The semiconductor is made up of two parts: a positively charged part and a negatively charged part. The negatively charged part is where electrons are when the light bulb is turned off. When you switch the light on this creates an electric charge which causes the electrons to pass out of the negatively charged part into the positive. This movement of electrons is what generates the clear, bright light that LED lighting is known for.

This is the way all LED lighting works, including LED panels.

What Are The Advantages Of LED panels?

LED panels are a type of LED lighting used in both domestic and commercial applications. These are basically large panels containing lots of LED bulbs, and have a significant number of benefits of traditional halogen and fluorescent lights.

LED panels are significantly longer lasting than traditional lighting. Traditional light bulbs will last for 750 hours of constant use. LEDs, on the other hand, will last for 50,000 hours of constant use. This is the equivalent of twenty years! This means that you will not need to purchase a replacement light bulb for ages, saving you money in the long run.

Another benefit of LED panels is that they are more energy efficient than other lighting methods. Traditional lights lose a lot of light as heat. This means that you are spending a lot of money on your electricity bill when a great deal of the electricity is not converting into light at all! LED lights convert a lot more electricity into light which means that they do not lose nearly as much as heat. This makes them a lot more energy efficient than traditional lights, which again will save you money.

Previously, LED panels have been very bright which means that they could not be used for everyday use but were more suited to use in warehouses. However LED panel lights now come in a variety of sizes and wattage so that you can purchase panels for use in your home. Certain panel lights have been developed that produce the same amount of light as a traditional 60 watt bulb, the customary wattage in the home.
