The negative effects for this for of lights are that each tube posesses a small amount of mercury vapour, a toxic heavy metal. This could provide not really a health risk once the tubes are broken, but could 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 constantly have to have a ballast to control the flow of power through the lamp. A starter is incorporated in the circuit to heat the contact ends with the tube that ionizes the mercury vapour creating UV light. The inside of the tube is coated with a phosphor material that glows when encountered with the UV light manufactured by the mercury in the fluorescent tube.
Recent developments in SMD (Surface Mount Diode) LED technology have now resulted in LED based fluorescent tubes have become a real possibility. LEDs are a extremely effective way of lighting product composed of small chips of conductive material that release light when a current is used in their mind. They contain no filaments and may produce approximately 25 times more light per watt than conventional lamps.
LEDs require less energy within their manufacture than fluorescent tubes, in support of 3% of the energy they’ll consume over their endurance is consumed within their manufacture, and they are also made out of non toxic materials. The tubes are made of polycarbonate, a material that is certainly more robust and sturdy than glass, so accidents won’t require special cleanup procedures.
While LED underwater lights is costlier than existing fluorescents at face value, they will last as long as Much as long, while consuming 65% less energy. For most general purpose lighting applications they additional tariff of the LED technology will greater than spend on itself inside first 18 months.
The only drawback is the tighter beam angle from the LEDs, although some tubes are produce of a polycarbonate light diffusing material, others have a narrow focus which may ‘t be well suited for replacing existing tubes. Many fluorescent fixtures are designed with reflectors that really help to distribute the sunshine from your tubes evenly in their intended environment. This is the problem similar to the fact that was faced when compact fluorescents began replacing incandescent lights, it is a problem that will soon be overcome and allow faster adoption of the emerging lighting technology.
