The world in which we live only has a certain amount of natural resources in the form of coal, gas, and oil. Carrying on with the usage of these resources at the rate we are will cause them to be depleted within decades and the impact on future generations will be huge. There are many ways in which small changes can add up to huge significant positive impacts on maintaining natural resources.
Over the past couple of decades there has been an EU directive that has forced us to replace our incandescent light bulbs that we have it home to new energy efficient ones in the form of LED type bulbs.
The average households spends 5% of its energy costs on light fighting, so by spending a small amount of money replacing the most commonly used lights in the home, the savings can soon add up.
Light emitting diode or LED lighting uses over 75% of the energy of incandescent bulbs and can last over 20 to 30 times longer. It has been estimated that in a country the size of The United States of America within a 20 year period, if incandescent bulbs were replaced with LED lighting then it would save the equivalent of 44 large electric power stations annual power production.
In affect the more lumens a light fitting has, the brighter it will be. Swapping from older type bulbs to new energy saving bulbs the following equivalents will be required. A standard house hold incandescent bulb of 40 Watts is the equivalent of 450 lumens, a 60 watt incandescent bulb is the equivalent of 800 lumens, and a 100watt incandescent bulb is the equivalent to 1600 lumens.
What are lumens? When we purchase a new light fitting they have 2 different measurements associated with them. The first is the wattage, this measures the amount of electrical current that the light fitting will use, so this is a measure of its power. The second measurement is lumens, and this is a measure of how bright the light is. One lumen is the equivalent of one candle, one foot away.
Factories, shops and many other commercial buildings have also had to follow suit in the type of lights that they use. Whilst out shopping at your local supermarket if you were to look up at the ceiling you would see a whole host of panels and every few will be a 600×600 led ceiling fitting.
The 600×600 LED panel will give off a very even intensity of light that is white in colour. This colour of light helps to reflect off of surfaces helping in retail type situations where good lighting is required. Expected lifespan of a 600×600 ceiling panel is roughly 50,000 hours; this makes the maintenance of them very cost effect as they will not need to be changed as often.
An average output of a 600×600 LED ceiling panel is 3300 lumens, which offers a very good light output. The lights usually require a 45 watt electrical current. The colour of the 600×600 ceiling panel is usually a natural white 4200K. This figure is the colour temperature of the bulb measured in degrees Kelvin, a figure of 2700K will have a yellowish tinge and a higher figure of 8000K will have a blue tinge.
