Cold Cathode Fluorescent Lighting Cons And Pros

A cold cathode fluorescent lighting is a very useful system that uses specific characteristics of electrons. At an operating temperature of approximately 200 degrees of C, the electrode is not so hot, at least comparing it with the operating temperature of the usually used F lamp, which is up to 900 degrees of Celsius. This makes them very useful when it comes to various temperature sensitive devices.

They still operate on almost the same principle. Lamps are filled with gas, and neon lamps use coated tungsten coil to discharge it. These types of lamps produce thermionic emission, while CCFL doesn't need so high temperatures to do the same thing, because they don't operate in thermionic manner.

These lamps emit very pleasing, but bright white light, although they are quite thin and significantly smaller than regular ones. Besides, they have significantly longer life, and that makes them perfect for using them for back lights.

Thanks to the fact they don't produce so high temperature, they can be used very close to different electronic components that are very sensitive to high temperatures. That's why these lamps are just ideal for back lights behind your laptop's or TV's screen. The light gets diffused by the panel behind the screen.

The main difference is in the type of electronic discharge. While regular lamps discharge electrons by heating electrodes, this type of lamps doesn't heat those electrodes. It has significantly lower power consumption, and, as a result, the temperature of the lamp itself is significantly lower.

This illuminating system uses a discharge in mercury vapor to develop ultraviolet light. The reflecting coating on the inside of the lamp after that emits visible light. Luminous tubing which is larger than 20mm and operates on a current of 120 to 240 mA is often used for general lights, but also for illuminating the inside of your car, for example.

These bulbs have a thinner tube diameter, which allows them to run cooler, and last longer. They are fully dimmable, and it means that their life doesn't become every time you switch it on. Ordinary tube's life gets shorter by approximately three hours every single time you switch it on, and this really is a significant improvement. Besides, they last much longer than other types of similar fixtures.

These bulbs emit very nice, appealing white light. They cost more, but it is worth it. They really do last longer, and they also never flick. Neon flicking can really be annoying, especially if it is hard to replace the bulb, thanks to its position. With these bulbs, you won't have to worry about it. As long as it lights, the light is impeccable.

Cold cathode fluorescent lighting has higher prices, and sometimes you won't be able to find the replacing bulbs easily, but they have so many advantages you should choose them anyway. It might be more expensive to install them, but they will last longer and provide pleasing, dependable light without causing damages to your environment. You will be satisfied with your choice.
