In nature fluorescent animals already for ages use their own lightening system for several reasons.To be able to show off on partners, to scare enemies away, to lurk prey animals nearby and to get a bit of light true real darkness in deep seas and ocean bottoms.
Fluor lightning used by animals has become an inspiration to develop a light source, that helps us to save energy and still have a functional lightning. The CFL light bulb.
Incandescent light bulbs are the most familiar type of light bulb used in almost all homes. This type of lighting, unfortunately, is also the most inefficient type of lighting. In an incandescent light bulb, electric current heats up a metal filament making it glow white-hot and give off light. The reason these bulbs waste energy is because only 5% of the electricity is actually used to produce light. The remaining 95% ends up as heat.
During the summer this heat causes your cooling requirements to go up and makes your air conditioner work harder. During the winter the extra heat might seem like a bonus, but it is a very expensive way to pay for a little extra heat.Compact fluorescents use about 65% less energy than standard incandescent light bulbs and last 10-20 times longer. For example, a 100W incandescent bulb will cost approximately 75 cents to purchase and last 750 hours. To use a lamp with this bulb for 3 years you will go through 6 bulbs ($4.50 total) and spend about $35 in electricity. On the other hand, to use that same lamp with a compact fluorescent for 3 years you will spend $11 on a bulb that will last almost 7 years. Additionally, you will spend only $8.00 on electricity throughout the initial 3 years. That is a total operating cost of $19.00 for a CFL, compared to $39.50 for an incandescent bulb. So, for spending a little more on the initial bulb you can save more than $20 on each lamp.
Modern advancements in CFLs have enabled them to emit a warmer more welcoming atmosphere, unlike the fluorescents of the past. You can now buy CFLs for indoor and outdoor use and you can now find types to fit almost any light fixture in your home. For general usage, 1 watt of fluorescent lighting equals the light output of 4 watts of incandescent lighting. That is a huge, money saving difference.
The environmental benefits of switching to compact fluorescent lights are substantial. For example, using a single 20-watt compact fluorescent bulb instead of a 75-watt incandescent bulb saves over 550 kWh of electricity over its lifetime. If your electricity is produced from burning coal, using a CFL would save 500 pounds of coal that would release 1,300 pounds of carbon dioxide and 20 pounds of sulfur dioxide, and a variety of other harmful pollutants.
So it stays usefull to study nature, for it delivers us the best and safest products mankind can make on the long run.
