There are many general service fluorescent tubes on the market place today, until recently these were considered the most cost effective lighting solution available. The downside for this for of lights are that many tube posesses a small amount of mercury vapour, a toxic rock. This will provide not only a health risks once the tubes are broken, but tend to also accumulate in landfills before entering water table or causing further pollution.
Fluorescent lamps use electricity to excite mercury vapour inside glass tube and constantly have to have a ballast to control the flow of power over the lamp. A starter is within the circuit to heat the contact ends of the tube that ionizes the mercury vapour creating UV light. Inside the tube is coated with a phosphor material that glows when encountered with the UV light made by the mercury inside the fluorescent tube.
Recent developments in SMD (Surface Mount Diode) LED technology have resulted in LED based fluorescent tubes are a real possibility. LEDs can be a more effective type of lighting product comprising small chips of conductive material that release light each time a current is used in their mind. They contain no filaments which enable it to produce around 25 times more light per watt than conventional light bulbs.
LEDs require much less energy of their manufacture than fluorescent tubes, and only 3% in the energy they are going to consume over their endurance is consumed within their manufacture, plus they are also made out of non-toxic materials. The tubes are made of polycarbonate, a material that is more robust and sturdy than glass, so accidents will not likely require special cleanup procedures.
While LED technology is higher priced than existing fluorescents at face value, they are going to last as long as Ten times so long as, while consuming 65% less energy. In LED underwater lights lighting applications they additional tariff of the LED technology will greater than pay for itself from the first 18 months.
The only real drawback may be the tighter beam angle with the LEDs, while many tubes are manufactured from a polycarbonate light diffusing material, others use a narrow focus which may stop suited to replacing existing tubes. Many fluorescent fixtures were created with reflectors that help to distribute the sunshine from the tubes evenly inside their intended environment. This is the problem comparable to what was faced when compact fluorescents began replacing incandescent lamps, it is a problem that will soon be overcome and invite faster adoption of this emerging lighting technology.
