How to save on house lighting – light bulb analysis

Lately, there is a lot of news in the media about saving energy. There are many ways to save energy and contribute to environmental protection by buying less and creating less waste while saving on your home budget.

The first and simplest step is to consider home lighting. Household lighting represents 25% of total electricity consumption in households so it is very clear that savings can be significant.

Let’s meet a little closer to the offer of lighting in Croatia today. On the market, there are 3 basic “types” of lighting. The first and oldest classic bulb (the one with tungsten thread), the other one that has been present for a while in the market is a CFL bulb and the third is an LED bulb.

By development of the latest technology and offers on the market, the situation from an ecological and viable aspect is changing and needs to be looked at objectively, so we in the Sunce Association have decided to explore the best options for you.

1. CLASSIC LIGHT BULB – This lamp type has been used for over 100 years and everyone is clear with the fact that it is an outdated and inadequate technology. It works on the principle of creating light by passing the current through the tungsten thread that warms up and shines the light. It’s pretty ineffective because about 90% of energy is lost on heating, it has a short life of 1200 hours, but it is warmly bright yellow pleasant to the eye and similar to sunlight.

2. CFL (SAVE) bulb – has been in the market for 20 years now and has been widely used. It works by energizing a mercury stream of pipes that produce ultraviolet light, passing through the phosphor layer inside the tube and ultimately producing fluorescence by the visible light. By using this type of bulb, we use significantly less current, lasts significantly longer (8000 hours) than classic bulbs, but their cost-effectiveness from an ecological viewpoint is as disputed as it contains poisonous elements such as mercury and phosphorus.

3. LED bulb – The LED name is an acronym that comes from the English word “Light emitting diode”. Although it has been on the offer for a few years now, only recent LED technology has developed enough to be effective in household use. It works by tiny semiconductors in it that create light. They have a much longer lifespan (25000-50000 hours) and use the least energy and therefore the biggest savings. Their only drawback is still high prices.

Everyone is talking about how to save, but we can hardly come to the information as to how much money is actually saved, including also the aspects of ecology and sustainable development, so we just started out with simple maths, sat on the table and got specific data.

From the table above it is clear which types of bulbs save the most current. If we look at how much we buy/ spend the material, math is also on the side of the LED because in 10 years we will still use 1 LED bulb, while for the same period will throw 4 CFL bulbs (containing mercury and phosphorus !!!) or 25 of classic bulbs.
