"Тень" катода на люминофоре :)
При тестовом включении одной из двух купленных ЛБ8-3 VII 72 от СПО Светотехника на люминофоре возникла "тень" от катода. Ртуть испарилась с противоположной стороны и спираль помешала оседанию ее паров под ней. Потом при переключении питающего провода на второй штырек все исчезло :). В реальности лампа светит ярче. К сожалению, один цоколь у нее болтается, как и у второй такой же ЛЛ.
