There are many general service fluorescent tubes in the market place today, as yet they were considered probably the most energy efficient lighting solution available. The negative effects to this for of lights are that every tube contains a little bit of mercury vapour, a toxic rock. This could provide not really a health risk if 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 the glass tube and always need a ballast to regulate the flow of power through the lamp. A starter is in the circuit to heat the contact ends from the tube that ionizes the mercury vapour creating UV light. The interior of the tube is coated using a phosphor material that glows when subjected to the UV light made by the mercury inside the fluorescent tube.
Recent developments in SMD (Surface Mount Diode) LED technology have recently meant that LED based fluorescent tubes are possible. LEDs certainly are a extremely effective kind of lighting product comprising small chips of conductive material that release light each time a current is used for many years. They contain no filaments which enable it to produce around 25 times more light per watt than conventional bulbs.
LEDs require far less energy within their manufacture than fluorescent tubes, in support of 3% from the energy they’ll consume over their life span is consumed within their manufacture, and they are generally also produced from non toxic materials. LED high bay lighting fixtures are manufactured from polycarbonate, a fabric which is better and durable than glass, so accidents will not likely require special cleanup procedures.
While LED technology is costlier than existing fluorescents at face value, they’re going to last up to Much so long, while consuming 65% less energy. In many general purpose lighting applications they additional cost of the LED technology will greater than spend on itself within the first 18 months.
The sole drawback is the tighter beam angle with the LEDs, even though some tubes are produced from a polycarbonate light diffusing material, others possess a narrow focus which may ‘t be ideal for replacing existing tubes. Many fluorescent fixtures are designed with reflectors that help to distribute the light in the tubes evenly of their intended environment. This is a problem comparable to what was faced when compact fluorescents began replacing incandescent lights, it is a problem that will soon be overcome and invite faster adoption on this emerging lighting technology.
