LED Fluorescent Tubes With Energy Savings

What about LED fluorescent tubes?  The disadvantage to this type of lighting is that each light tube contains a small amount of mercury vapour, a toxic heavy metal. This can provide not just a health risk whenever the light tubes are broken, but can also accumulate in landfills before entering the water table or causing further pollution.

The fluorescent light bulbs 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 of the light tubes which ionizes the mercury vapour creating the UV lights. The inside of the light tube is coated with a phosphor material which glows whenever exposed to the UV light produced by the mercury inside the fluorescent light tube.

Recent developments in SMD LED technology have now showed that LED fluorescent tubes are presently a reality. They are a more efficient form of lighting product consisting of small chips of conductive material which release light when a current is applied to them. They contain no filaments and can produce up to 25 times more light per watt than traditional light bulbs.

LED lighting bulbs need lesser energy in their manufacture than fluorescent light tubes, and only 3% of the energy they will consume over their life expectancy is consumed in their manufacture, and they are also produced from non toxic materials. The light tubes are made from polycarbonate, a material that is more robust and durable than glass, so accidents will not need special cleanup procedures.

Although this technology is more costly than existing fluorescent lights at face value, their lifespan is about 10 times as long, while consuming 65% lesser energy. In most general purpose lighting applications the additional cost of the LED technology will more than pay for itself within the first 18 months.

The disadvantage is that the tighter beam angle of the LED lighting bulb products, while some fluorescent tubes are manufactured from a polycarbonate light diffusing material, while others may have a narrow focus which are not be suitable for replacing existing light tubes. 

Many fluorescent fixtures are in fact designed with reflectors which assist to distribute the light from the light tubes evenly in their environment. This is a issue very similar to what was faced whenever compact fluorescent light tubes began replacing incandescent lighting bulbs, this is a problem which will soon be overcome and allow faster adoption of this emerging lighting technology.
