Работа по тандемной схеме ламп разного типа, но с близким номинальным током :)
Так как рабочий ток Т8 10Вт Osram и Т5 8Вт ЛБ8-3 близкий - 0,17 и 0,145А, то лампочки отлично зажигаются при включении последовательно с ПРА 2УБИ8 :). Суммарный ток схемы при напряжении сети 220В составил 0,152А. Падение напряжения на ЛБ8-3 составило 63В, а на Т8 10Вт Osram L 10W/827: http://fotkidepo.ru/?id=photo:970440 - 72В. На дросселе на фото ток указан в 0,17А, тогда как на ином ПРА 2УБИ8: http://fotkidepo.ru/?id=photo:983682 номинальный ток указан в 0,145А, видимо изготавливались 8Вт лампы с разным значением его...
