In recent years, LED lighting has entered our daily lives en masse, especially after the cheaper production and, consequently, the appearance on the market at more affordable prices. As this type of lighting is characterized by indisputable advantages over all other types and since obviously the future belongs to it, we will acquaint you in detail with its main characteristics and corresponding advantages.
An important point in the lighting fixtures are the energy-saving light bulbs, which, although inferior in characteristics to the LED ones, are significantly more economical than ordinary light bulbs and are widely used in everyday life.
The facts are eloquent enough. An ordinary incandescent lamp has a maximum lifespan of about 1,500 hours or an average of 1,000. With an average operation of 3 hours per day, the bulb will last between 1 and 1.5 years, after which it will burn out. The lifespan of LED lighting is between 50,000 and 100,000 hours, which means that in the pessimistic version you will use the lighting 5-10 depending on how you use it.
In addition to these two types on the market are sold, etc. energy saving bulbs or these are compact fluorescent lamps. It is correct to include them in the comparison, because they are widespread and their price is also affordable. The duration of this bulb is 6,000 - 10,000 hours, which compared to the incandescent bulb is many times longer, but compared to the LED bulb is many times less.
The old incandescent bulbs were produced with several levels of consumption - 100 watts, 75 watts, 60 watts, etc. It is easy for anyone to calculate the consumption of these bulbs, knowing that this power is per hour, ie. consumes 100 watts of electricity per hour, and 1,000 watts is equal to one kilowatt, which is the unit of electricity consumed in your monthly electricity bill. It is important to say that in 2009 the production of these bulbs began to be phased out, and in 2013 the smallest of them - 25 watts - was banned from production. Although they are no longer produced, most of them are freely available in stores, while the already produced stocks are sold.
The consumption of energy-saving lighting is significantly less - on average about 4 times, and the bulbs sold on the market vary between 7-8 and twenty watts in bright bulbs.
Consumption of LED bulbs is 3-4 times lower than energy saving. Mass LED bulbs have a consumption between 2 and 7-8 watts. The most powerful reach up to ten watts.
This indicator measures the "amount" of light that the bulb produces. In the past, when there was only one type of light bulb, their electricity consumption, measured in watts, also served as a measure of the light produced by the light bulb. It was logical that the more he consumed, the more light he would produce. With the advent of new energy-saving light bulbs and then LED bulbs, this has changed and electricity consumption is no longer a correct measure of light, simply because different light bulbs produce different amounts of light with one watt of electricity consumed.
The illuminance produced by a light bulb is measured in lumens. It is a correct measure of the light produced, and the light efficiency is called the amount of light produced by one watt of electricity consumed.
To guide you, we will give you how much light, measured in lumens, the old incandescent bulbs produced - because they produced about 10-15 lumens from one watt of electricity. The 100 watt light bulb gave about 1300 lumens, the 75 watt light bulb - 900-1050 lumens, the 40 watt light bulb - about 400 lumens. Obviously, they are characterized by the lowest light efficiency.
Energy saving light bulbs are significantly more economical. An 8-watt light bulb produces as much light as old 40-watt light bulbs - 350 to 400 lumens, and a 12-watt light bulb produces as much as an old 60-watt light bulb - about 600 lumens. We can summarize that these bulbs produce up to 50-60 lumens per watt of electricity used.
In comparison, a 10-watt LED bulb generates between 900 and 1,000 lumens, and a 15-watt light bulb generates 1,300 lumens. Thus, without a doubt, LED bulbs, producing about 90-100 lumens of one watt of electricity, are proving to be a leader in economical lighting.
Color of light
The light generated by LED bulbs and compact fluorescent bulbs, also called energy-saving bulbs, can vary in different colors, which are measured in kelvins. For example, a light with 2,700 kelvins is called "warm white" because it is a softer color and is preferred for homes, and a light with more than 4,000 kelvins is called "cold white" and is mainly suitable for offices and office buildings.
