I have built a 10m x 5m sheet steel workshop that is off grid. I have fitted three 5ft fluorescent strip lights. The workshop is powered by a 6kva generator. the problem is that if I switch the lights on and then power up the 2000 watt saw the lights go out and are reluctant to come on again. I think they are switch start lamps. I am a carpenter not an electrition. can anyone out there help me please? What lights would you recomend?
