CFL bulbs

.





Popular Mechanics recently published an article about CFLs on their website that reaches some startling conclusions.

The conclusions were based on measurements of colour temperature, brightness and wattage; and observations by three of their staff and a lighting expert:

Even though the incandescent bulbs measured slightly brighter than the equivalent CFLs, the testers didn’t see any dramatic difference in brightness.

What was a revelation and a surprise was when it came to the overall quality of the light, all the CFLs scored higher than the incandescent control bulb. In other words, the new fluorescent bulbs aren’t just better for both your wallet and the environment; they actually produce a better quality of light.

CFLs use about 70% less electricity than ordinary bulbs. The average modern home has about 40 ordinary light bulbs in total. Some are lit for longer periods than others, but on average — replacing forty 75-watt incandescent bulbs with CFLs would realistically save over €45 a year. Remember also that CFL bulbs last up to 5 years or more while ordinary bulbs have a life of a year or less – that means CFLs pay for themselves twice over in their lifetime.
