I have the ADJ Dotz Flood (2014/15 model). One of the units works fine for about 10 minutes, then the lights go out (the fan continues running). Switching off and on again always brings the lights back on but only for another 5-10 minutes.
Any idea what could be causing this? I'm sure it isn't overheating because a) the fan stays on and b) I don't have to leave it switched off for any length of time for it to work again - a quick off-on works.
