Скачать или смотреть Philips T8 fluorescent lamp operation with electronic ballast

T8 fluorescent lamp: Philips Master TL-D Super 80 18W Polish made H3 August 2023 which I use daily for at least 7 hours a day on average 8 hours a day and for 15 months now where in total it has reached approximately 3500 hours of operation and has already started to blacking a little at the edges, it certainly has twice as much life but for a lamp where it has an average life of 15,000 hours with the use I make it should last about 7-8 years where it is impossible to last that long, unfortunately the productions in fluorescents from Philips and Osram have deteriorated a lot in the last few years almost a decade and now they last very little depending on the use and the ballast where some observe that these new productions fluorescent last longer and even much longer with the use of electronic ballast
