Isotronic 11W
Lamp Isotronic 11W use a little modified wiring, where doesn't exists starting circuit with a diac. Lamp starts probably thanks to capacitor C1.

Luxtek 8W


Lamp Luxtek 8W use classic wiring with a small changes. Interesting is only thermistor, which probably makes light start and filament preheating.

PHILIPS ECOTONE 11W


Lamp PHILIPS ECOTONE 11W use again simplified wiring like a Isotronic lamp. This lamp compared to other has a right dimensed components, that electronics probably can live longer. Wiring is less cheated than others. It has coil L2 for blocking HF interference and capacitor C1 for voltage 1200V, which is very much stressed. Tube is superior compared to a no-name types. Light color "warm white" brings light of classic bulb and doesn't have a small pink tone like others. Tube is a little longer and have much light compared to others 11W types. All these lamps, which I have from several series have identical color tone and brilliance. Compared to lamps MAWAY, where every item have different color tone, some have destroyed electronics, some have pipe with a lost vacuum etc... It is seen, that lamps from marked manufacturers have guaranteed parameters and better quality than no-name.

IKEA 7W
Lamp IKEA 7W has classic wiring like a Luxar 11W. Component values are modified to a lower power. Parts are enough voltage dimensed. Failure was overburned one of filaments. Lamp was on continuous for one year, which is over 8500 hours. Life time corresponds to a label specifications.

SINECAN 5 2x 26-30W
Electronic ballast SINECAN 5 for two fluorescent tubes has identical circuit like most of compact fluorescent lamps. Little differency is in powering tubes before D6 diode and wiring of start capacitors C10 a C11 about tubes. I don't understand exactly why this is wired this way. Ballast doesn't have fuse, but only thin wire. Ballasts was broken due to blowed electrolytic capacitors. It breaks transistors and resistors R3, R4, R5 and R6.

PHILIPS GENIE 14W
This bulb has almost identical circuit to their 11W variant. It has two additional protect dioded D6 and D7. Values of few components are a little changed. Transistors are more powerful types 13003.
