Low consumption bulbs

The low consumption light bulb boxes say: a new 11 watt light bulb provides as much light as a 60 watt incandescent light bulb. And it's not a publicity stunt.

Typical incandescent lamps include a tungsten filament. During the passage of the electric current, the filament heats up and generates light. As a result, much of the energy you consume is converted to heat, and only 1.5% of that energy is converted to light.

In low-energy light bulbs, 15% of the absorbed energy is converted to light. They work in a similar way to fluorescent tubes, and although they are more expensive than incandescent tubes, they last much longer: an average of 12,000 hours, and incandescent lamps last 1,000 hours.

This efficiency allows you to save a lot of money on your electricity bill. For example, replacing a 75-watt incandescent light bulb with an 18-watt fluorescent light bulb will save 570 kWh over its lifetime, approximately 62 euros, taking the current price of electricity. Not only that, but we will also avoid the emission of half a tonnage of CO2 into the atmosphere.

Since September last year, the manufacture of incandescent light bulbs above 100 watts has been banned in Europe. Next year, 75 watts will be banned. The traditional lamps will gradually disappear from the shelves of the supermarkets.
