Buying Guide: low consumption bulbs
Energy-saving lamps: Starting last September 2009, began the gradual banning the old incandescent bulbs in favor of new energy-saving lamps. The replacement of old light bulbs materializes in stages, we started from the 100-watt bulbs and lamps of any type of power buffed. In September 2010, will be the turn of incandescent lamps of 75 W, in September 2011 of the 60W, in September 2012 will touch the lamps 15, 25 and 40 watts, and concluded in 2016 with the banning of all light bulbs class C.
To better convey the idea of the benefits of new energy-saving lamps must be said that the latter turn out to be mercury-free and provide an average reduction of 80% of cost of lighting: with the same lighting, in fact, saving light bulbs energy consume one-fifth of a normal incandescent bulb. For example, you can replace a 100W incandescent bulb with a 20W energy saving and the average length ranging from 5,000 to 15,000 hours.
Here are some tips on how to choose the energy-saving bulb that best suits our needs.
Types of light bulbs with low energy consumption:
The energy-saving lamps, made in all shapes and colors, are available with very warm light (ie with a low color temperature) and cold light (ie with a high color temperature). And 'advisable to choose light bulbs screwed onto the base, tubular models are in fact more delicate and can break easily.
Where to install energy saving light bulbs:
And 'advisable installing saving light bulbs energetic premises in which required two or more hours of light per day. It is therefore recommended that the installation of energy saving light bulbs in rooms where you are staying just a few minutes a week. In these rooms, we recommend choosing halogen lamps, but do not fall into the category of energy saving light bulbs and require 10% more power.
Purchase costs and savings generated by the use of energy saving light bulbs:
Beware of energy saving light bulbs at competitive prices, as economic fact have a life and a much lower yield. The excellent energy-saving lamps, made by brands "safe" cost an average of around 10 Euros. Although the costs of energy-saving bulbs are much more sustained than traditional incandescent bulbs, the benefits are many. They range from the very small presence of mercury at very low CO2 emissions, through the long life of the individual energy saving lamp equal to ten incandescent lamps. In terms of consumption then the difference is huge: for 10,000 hours of use lampadins draw each incandescent consumes 90 € of electricity and 390 kilograms of CO2, while the energy-saving bulb consumes only electricity and 18 € and 78 kilograms of CO2. To better understand the savings just count the number of bulbs that we have at home.
LED Bulbs:
The LEDs, light emitting diodes, currently on the market appear to be still very expensive compared to halogen or energy saving. In the coming years, however, sales of LED for home use are likely to increase significantly. For the moment, however, let's focus on more affordable alternatives.
Disposal energy saving light bulbs:
Very important is the disposal of energy saving light bulbs, which, despite no evidence of mercury, however, are considered toxic waste. E 'therefore must not dispose of as household waste but contact at recycling centers and retailers who collect the free energy-saving lamps.
