For those amongst us who has ever wondered what HID ballast does, it is very easy to explain. This small piece of equipment is used to control the power in a gas-filled bulb fitting. The MH ballast does much the same thing and these can be found in fluorescent lights and anything with neon gas inside. Indeed, what it does is to limit the flow of current through the gas so making it cheaper to operate.
These kinds of gas-filled bulbs must have a piece of equipment like this installed because there is no way of controlling the flow of power otherwise. If the lamp was to be operated without this equipment then it would certainly fail for sure.
The electro-magnet variety will allow the light to illuminate on each half cycle of the power as it cycles through the unit. This is what makes fluorescent lights flicker and this can cause some problem in people who are prone to headaches or epileptic fits. There are different pieces of equipment which can minimize this kind of fluctuation by attaching it to two lamps so that one lights while the other one is off and vice versa.
On the other hand, electronic styles of this equipment will use a different method to transform the voltage and this too will cut down on flickering and all the problems that it brings. This is probably the cheapest system too since it runs at cooler temperatures meaning that it uses less power.
Many people wonder how the fluorescent bulbs works and they mostly know that this is a gas-filled bulb. What is actually contained inside is mercury vapor which will only produce ultra violet light. But the lamp has a phosphorescent coating which glows once exposed to the ultra violet light and the result is bright and clear illumination. Although these fittings are larger than the normal tungsten bulbs, they do a lot longer and are much cheaper to run over time.
Today, everyone is aware that we must start cutting back on fuel consumption and as power is produced from fossil fuels sometimes, the need to save electricity is paramount. The newer coiled bulbs for home use are much more compact than the originals and many people are now replacing the old tungsten varieties with these. They are more expensive though but they are a whole lot longer which makes them price competitive over time.
Some countries have already phased out the old tungsten variety of bulbs and many more countries are following suit every year. Sometimes it should be impossible to purchase anything but this energy-efficient bulb which will obviously bring down prices even more as we progress.
Although most of us take lighting for granted, it is obvious that it is a far more complex system being used than first thought. Replacing the inside workings of these lamps is easier since online companies started to offer them for sale and a quick search online will show what is available in this area.
