At the moment, energy-saving lamps (CLF) are widely used.
To reduce the dimensions of ballast chokes, they use the schemes of high-frequency voltage converters, which several times reduce the dimensions of the chokes.
At the failure of the electronic ballast is easily repaired.
But when the threads of incandescent are cut or a glass colummer itself is cracking, the light is usually ejected.
Although compact fluorescent lamps (energy-saving) exist warranty period and even up to 3 years. But the buyer often faces the fact that the lamp does not burn, and he did not save the packaging, a shopping check, the owner of the store went bankrupt, i.e. On the reasons independent of the consumer, there is no possibility to exchange a faulty light bulb.
I got an energy-saving light with an inadvertently broken flask and the use of the throttle was found immediately.
The kitchen operates the daylight lamp by 30 watts, which has recently become nervous to his wife; buzzing, long does not ignite or flashes. The wife, of course, with hints, that the house was left without a man, and the grandchildren of only 5 years and the present assistant will not wait for her.
Ballast choke of a compact fluorescent lamp (CLD) at first experienced on the stand,
From the active lamp of daylight, the starter and throttle threw, connected the scarf of the electronic ballast. Now the LDS lights up instantly, does not blink under reduced voltage and does not buzz.
