Welcome to the “Greener” Bulbs? Webpage |
|
|
Its aim was to investigate which brand of light bulb was the most energy efficient and had the least impact on the native environment, and common technological devices. NCEA level 2 physics and biology scientific principles, as well as extended knowledge, were used in these experiments.
This site compares the benefits of Compact Fluorescent Light bulbs (CFLs
or Eco-bulbs) to those of regular incandescent lamps. The experiments use three brands of spiral 20W CFL (Philips, Elite,
Switch and Ecobulb Brand) and one of the most common 100W incandescent lamp
brands (Philips) for the most part. However some tests refer to CFLs in general.
This site aims to educate consumers about the advantages and
disadvantages of CFLs. It does this by comparing the
“focus” bulbs with incandescent lamps in a number of areas. The conclusions can be found on the “Better Bulbs?” page.
Use the links to the left to learn more about the advantages and disadvantages of eco-bulbs.
NOTE: * Images used on this site are original except mercury image on
Mercury/Phosphorus ‘ Effects page (from en.wikipedia.org/wiki/mercury_(element)) *Only common brands of eco-bulbs were used * This project did not test eco-bulbs that were not spiral shaped or 20W * This project did not test other brands of 100W incandescent lamp * Using an incandescent lamp with lower power consumption was not considered in the tests. This was done to make the project manageable and concise. |
