Energy Efficient Light Bulbs
Energy efficient light bulbs are good for the environment is because they reduce energy consumption delaying the building of new power plants. This reduces the amount of mercury released from the production of energy from geothermal and fossil fuels (this type of generation accounts for approximately 20% of new zealand's total electricity production). Mercury is an element that occurs naturally in the environment and can be found.
Other sources of mercury include thermometers, barometers, some batteries While standard incandescent light bulbs cost only around $1, they typically last for only 1,000 hours and use significantly more energy. A good quality compact fluorescent lamp (cfl) costing around $5 should last between 6,000-15,000 hours while an efficient halogen spotlight costing $10 for should last 5,000 hours and a fluorescent tube costing around $9 should last 15,000 hours.
While energy efficient light bulbs are more expensive to buy at the counter, traditional incandescent light bulbs burn far more electricity and they don't last long by comparison. Therefore, buying efficient bulbs saves you money - more than $100 over the lifetime of a 20w cfl replacing a 100w incandescent.
Energy efficient light bulbs are the easiest first step consumers and businesses can take towards reducing their energy consumption. Products have gotten light years better in the past few years and, in my eyes, indisputably better for 99% of applications. Both cfl and led light bulbs run much cooler than incandescent bulbs, use energy much more efficiently, and do offer saving on your electricity bill. I am a vendor of energy efficient bulbs, so perhaps i am a bit biased, but i don't know why everyone doesn't switch today. I swung by a bunnings home improvement store saturday morning and noticed they have the bright effects 13w compact fluorescent light bulbs (4-pack) for $7.
You can save more than $30 and more in electricity cost and produce about 75% less heat. If everyone in our city changed their light bulbs to energy-efficient light bulbs imagine how much energy we would be conserving and also helping our earth.

The latest generations of energy efficient light bulbs offered by the major manufacturers are no longer very large. In some cases, they are slightly smaller than their gls equivalent and with the new classic shapes look almost the same as gls bulbs. Energy efficient light bulbs need to be left switched on for more than 45 minutes as they consume so much energy when first switched on. There is no reason to keep a energy efficient light bulb switched on for longer than a normal gls bulb as they do not consume any greater energy during start up and run very efficiently immediately after the first 2 or 3 seconds. Cfls give a colder colour light than ordinary bulbs: under the energy saving trust's 'energy saving recommended' accreditation, cfls have to emit the same warm light level as gls bulbs - between 2600 and 2800 degrees kelvin. They operate at high frequency through their electronic controller at between 30,000-50,000 hertz (normal mains voltage cycles at just 50 hertz or cycles per second).
