Takie kondy miflexa po 1980r. już traciły pojemność,

Ten jeszcze spuchł na górze, bo nie jest zamykany metalowym wieczkiem jak Telpod, ale jakimś tworzywem. Elektrolityczne jednak były dość trwałe, zwłaszcza stare Telpody. Mam jeszcze Miflexa z 1975 r. z BMKs 1x40W zalanego takim bordowym lakiem na 220V i on wystrzelił dość spektakularnie.

@@cla829 A capacitor (230V) with a capacity of several μF connected in parallel to the network terminals increase the power factor of the lighting fixture. The metal capacitor like in this video (above 380V) can also be installed in series in the power supply system to eliminate the stroboscopic effect. Fluorescent lamps pulsate alternately at a frequency of 50 Hz. In this case, the fixture must use two or 3 fluorescent lamps. A fluorescent lamp connected behind the capacitor always burns out faster or it does not light up at all when the capacitor loses capacity. Capacitors do not have to be used, but modern meters count the consumption of reactive power, so a luminaire without a capacitor will generate additional costs and may be dangerous when lighting machines with rotors.

@@Meskel_light thank you for your answer i have a fixture 4x18w and i made a 4x18 in a wood of a old desk, i have another question: i have a 2 tubes of 18w (Philips TLD18w/33 and one tube have a black stain, is going in EOL?

@@cla829 When the fluorescent lamp turns on quickly and the blackness is less than a few centimeters, it will still work for a long time. It all depends on the manufacturer. Some fluorescent lamps turned completely black at the ends after 100 hours and lasted for several years, while others were slightly black and burned out. Moreover, old Soviet or Polish fluorescent lamps did not have shields on the electrodes, so they turned very black at the ends, but they worked for such a long time.
