Types of Tube Lights

There are many ways to provide lighting to an area. Whereas lighting options were originally limited to fire and then assorted torches, candles and lamps, technological advancements with electricity sparked a flurry of lighting advancements in the 19th century. Today, some of the most efficient means of providing lighting are tube lights.

Fluorescent Tubes
The production technology for today’s fluorescent tube lights was first developed in the early 20th century. Electricity is used to excite mercury vapor, which in turn causes the phosphor inside the tube to fluoresce and produce light that’s visible to the human eye. Fluorescent lights are often found in commercial settings and other areas where bright lighting is needed for long periods of time, because they are more energy efficient and last longer than incandescent bulbs.

Light Emitting Diode (LED) Tube Lights
Light emitting diode (LED) tube lights are a third type of tube lighting. LEDs produce light when their diode is switched on. This causes the electrons in the diode to release photons and produce electroluminescence. The color of light produced by the LED depends on the photon’s energy. These ultra-efficient, long-lasting lights have been used in a variety of applications, including both rigid and flexible tube lights.

 
Compact Fluorescent Lamp (CFL)
Compact fluorescent (CFL) tube lights continue to gain in popularity in both commercial and residential settings. Similar in nature to fluorescent tubes, CFLs produce light via the excitement of mercury vapor which causes phosphors to fluoresce and produce visible light. Instead of using an electromagnetic ballast, CFLs use a built-in electric ballast and can be used in sockets originally designed for incandescent bulbs.

The design and fabrication of this LED based lighting system took approximately 6 months from start to finish. As you may have read already, the goal was to match the light output of a 32 watt T8 fluorescent lamp while using significantly less energy. This is an ambitious task because T8 fluorescent lamps are the more efficient flavour of this technology. LED Tube that were designed are intended to run on sealed lead-acid batteries which means they can accept an input voltage of anywhere from 10.5 V to 13.5 V. This input voltage was chosen to make LED Tube compatible with solar or wind energy systems. This means that if your home or building is operating on solar or wind energy, you can connect LED Tube directly to the batteries and bypass the inverter. This allows you to purchase a smaller inverter and requires you to have less solar panels (due to the energy loss when converting from 12 VDC to 120 VAC).
