There are lots of general service fluorescent tubes on the market place today, up to now they were considered the most energy-efficient lighting solution available. The down-side to this for of lights are that all tube has a little mercury vapour, a toxic metal. This could provide not just a hazard to health when the tubes are broken, but could also accumulate in landfills before entering the lake table or causing further pollution.
Fluorescent lamps use electricity to excite mercury vapour within the glass tube and try to demand a ballast to modify the flow of power from the lamp. A starter influences circuit to heat the contact ends in the tube that ionizes the mercury vapour creating UV light. The interior of the tube is coated with 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 now resulted in LED based fluorescent tubes have become possible. LEDs can be a better way of lighting product made up of small chips of conductive material that release light whenever a current is applied for many years. They contain no filaments and will produce approximately 25 times more light per watt than conventional bulbs.
LEDs require much less energy within their manufacture than fluorescent tubes, and just 3% from the energy they will consume over their endurance is consumed in their manufacture, plus they are also made out of non toxic materials. The tubes are manufactured from polycarbonate, a fabric that’s better made and sturdy than glass, so accidents won’t require special cleanup procedures.
While LED technologies are higher priced than existing fluorescents at face value, they’ll last up to Much so long, while consuming 65% less energy. For most general purpose lighting applications they additional expense of the LED technology will more than pay for itself inside first 1 . 5 years.
The only real drawback could be the tighter beam angle of the LEDs, while many tubes are produced from a polycarbonate light diffusing material, others use a narrow focus that might stop well suited for replacing existing tubes. Many fluorescent fixtures were created with reflectors that really help to distribute the sunshine from your tubes evenly inside their intended environment. This is the problem similar to what was faced when compact fluorescents began replacing incandescent lamps, this can be a problem that can soon be overcome and permit faster adoption on this emerging lighting technology.
