I want a bright flashing display light. Imagine the sort of thing on a one armed bandit machine, that flashes a couple of times a second. And it would run for days on end. So either one of these which are rated at 5W:-
but the former is preferred as it contains all the necessary current control and is very easily replaceable without soldering.
Are these suitable? I'm concerned that as they run hot they'll be no different than an incandescent, suffering continuous thermal shock and mechanically breaking. Is there a more suitable high power LED for flashing or might I just as well use a traditional filament bulb?
There's Strobing very high power LEDs but that seems to deal more with frequency than resilience. There are some other questions too but again they seem to deal with implementation issues.
