Me and some guys were talking about canister lights today and how they flood. One of the guys asked me a question that i really did not have a good answer to. So here it is " If you turn you light on and off some during a dive is it more likely to flood??"
If it is a switch, I would say no. If it was a "twisty", then I would say your chances are higher in case you screwed it too much.

I would say no..... the switch is protected by a rubber boot...Quote:

I forget which of my lights this was, as one has a sealed lid, the other does not.... also insulating the water ingress...

I turn my lights off and on during the courses I teach and so far...I'll refrain from saying anything further so as not to jinx myself... :)
Theoretically, turning it on and off increases the potential for something to fail - which is I think where the advice to leave it on comes from.
With a halogen light (back before the earth cooled and when primary light failures were common) flipping it on was the time when the bulb was most likely to burn out.
If it is an HID, they prefer to be left on till they warm up and then left off until they cool down before you try to restrike it. With an LED it is no big deal.
