There are many general service fluorescent tubes available in the market place today, as yet these were considered one of the most energy efficient lighting solution available. The side effects for this for of lights are that each tube contains a small amount of mercury vapour, a toxic metal. This may provide not only a hazard to health once the tubes are broken, but can also accumulate in landfills before entering the water table or causing further pollution.
Fluorescent lamps use electricity to excite mercury vapour inside glass tube and try to demand a ballast to regulate the flow of power with the lamp. A starter is within the circuit to heat the contact ends of the tube that ionizes the mercury vapour creating UV light. The inside of the tube is coated having a phosphor material that glows when exposed to the UV light created by the mercury within the fluorescent tube.
Recent developments in SMD (Surface Mount Diode) LED technology have meant that LED based fluorescent tubes are possible. LEDs really are a extremely effective kind of lighting product composed of small chips of conductive material that release light whenever a current is used for many years. They contain no filaments which enable it to produce up to 25 times more light per watt than conventional bulbs.
LEDs require less energy of their manufacture than fluorescent tubes, simply 3% in the energy they’ll consume over their life span is consumed of their manufacture, and they are generally also produced from non toxic materials. The tubes are made from polycarbonate, a fabric that’s more robust and durable than glass, so accidents won’t require special cleanup procedures.
While LED technology is costlier than existing fluorescents at face value, they’re going to last as long as 10 x so long, while consuming 65% less energy. In outdoor LED flood lights lighting applications they additional tariff of the LED technology will a lot more than purchase itself inside first Eighteen months.
The only real drawback could be the tighter beam angle with the LEDs, although some tubes are produced from a polycarbonate light diffusing material, others use a narrow focus which may ‘t be suitable for replacing existing tubes. Many fluorescent fixtures are made with reflectors which help to distribute the light through the tubes evenly within their intended environment. This can be a problem comparable to the fact that was faced when compact fluorescents began replacing incandescent bulbs, this is a problem that may soon be overcome and permit faster adoption of the emerging lighting technology.
