Chances are either the ground connection is bad, or you have the wrong type of tubes installed in it.
Shop light fixtures generally need tubes made specifically for them; a normal rapid start tube won't reliably start in it, especially when humidity is high.
Humidity being the key variable you mentioned, it can produce the intermittent operation you refer to. Check all wires in the wire nut splices carefully for for signs of oxidation. All wires and connections should have a shiny bright surface. Clean or cut back wire to find good clean strands and reconnect. Check contacts on ballasts and pins on the tubes too. Don't neglect the sockets, as they are often not tinned, and tend to go first. A little CRC 2-12 or similar electrical spray on a rag to wet the contacts will prevent future oxidation- for a while at least. If you have high humidity routinely, put a bit of silicone into the wire nuts to keep moisture out in the future.
Apart from no, your question has no simple answer. Fluorescent lamps need a few kV to start them and have a 90V drop when running. All of that is provided by the "gear" needed to run a fluorescent lamp. In a compact fluorescent (CFL), the gear is inside the cap.
Since I know these days Havells Sylvania are manufacturing eco friendly lights, Havells lights doesn't produce heat anymore while glowing, so I think this is one of the favourable part for your requirment and yeah you Fluorescent light are safe enough for inside use.
it would start raining heavily
in the sea
Temperature at the start of the MEN'S race was 80° Fahrenheit (26° celsius) with 40% humidity Temperature at the start of the WOMEN'S race was 86° with 50% humidity
It provides a boost in voltage required to start the fluorescent process.
A feeling of giddyness, anxiety, excitement, etc. In the early stages of onset the user will start to notice slight perceptual changes. This is largely relative as to what hallucigenic substance the user has ingested, and how much of it. Lights may seem to glimmer or become intensified, object take on a comical appreaence, and you basically just start to feel reality slip away.
Short answer is no. Old fluorescent fixtures use to have ballasts that required considerable energy to start and warm up, if the light was switched on and off frequently then it would have been better just to leave it on, however this limitation has been solved since the early 1980's. You are doing yourself no favors by leaving a modern florescent light on
Check the distributor cap
Preheat, Instant start (also known as slimline) and rapid start. Also, rapid start is best for dimming!!
Crank but not start and run, possible. Not to crank, start or run, no. No lights or horn, no.
