There are LED underwater lights of general service fluorescent tubes available in the market place today, alternatives they were considered one of the most energy efficient lighting solution available. The down-side to the for of lighting is that all tube includes a little mercury vapour, a toxic heavy metal and rock. This will provide not really a health risks if the tubes are broken, but tend to also accumulate in landfills before entering the lake table or causing further pollution.
Fluorescent lamps use electricity to excite mercury vapour in the glass tube try to have to have a ballast to manage 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. Inside the tube is coated which has 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 now a reality. LEDs certainly are a more efficient way of lighting product consisting of small chips of conductive material that release light when a current is used for them. They contain no filaments and can produce around 25 times more light per watt than conventional light bulbs.
LEDs require less energy inside their manufacture than fluorescent tubes, and only 3% from the energy they’ll consume over their life-span is consumed inside their manufacture, and they are generally also manufactured from non-toxic materials. The tubes are made of polycarbonate, a material that’s better quality and sturdy than glass, so accidents will not likely require special cleanup procedures.
While LED technology is more expensive than existing fluorescents at face value, they’re going to last as long as 10 times so long, while consuming 65% less energy. In many general purpose lighting applications they additional expense of the LED technology will greater than purchase itself within the first 1 . 5 years.
The one drawback will be the tighter beam angle of the LEDs, even though some tubes are made of a polycarbonate light diffusing material, others have a very narrow focus which might ‘t be suitable for replacing existing tubes. Many fluorescent fixtures were created with reflectors that really help to distribute the lighting in the tubes evenly within their intended environment. It is a problem comparable to what was faced when compact fluorescents began replacing incandescent lamps, this can be a problem which will soon be overcome and invite faster adoption on this emerging lighting technology.
