Re: Short Time Running Of Fluorescents

Fluorescent lamp life decreases with switching cycles. The standard 3h switching cycles are 2h45 on, 15 min. off to achieve the expected life of 10000h to 15000h. According to Sylvania technical data, lamp life is reduce to 50% with 3 time more switching cycles per day (30 vs 10 switching cycles/day...

As I also have sensor with a dimmer in the staircase that requiere 25 VA minimum (timer set to 5 minutes), I s...
