And isn’t it better to return to the simple and reliable Russian designs? Among them can be attributed to the proposed technical solution.
Led bulb (abbreviated SL) can be seen today in almost every home. And for good reason-they are economical. Energy conservation is that SL, for example, with a declared capacity of 9 watts and current consumption of just from 0.065 A, is the analog of the output light of the incandescent lamp 60 W, which consumes several times more.
Inspired by the originality of technical solution, published in the journal “modelist-Konstruktor” No. 11’78, I modified the circuit for fluorescent lamps and for many years its use in residential lighting fixtures.
