I have most of my tactical and turbos programmed to low and max, but opposite of most people, I like low on the tight bezel position - I just like the feel of solid, tightened down light for my default/most often used mode. Have one bedside light thats moonlight/tight, low/loose.
I personally like the regular interface better and EDC a 1x14500 QAAX - which is a effectively like a moonlight/max tactical, yet only click or two away from low and med.
I would clean and check all threads and see if that helps. Make sure when the head is loosened, that it is loosened a good 1/4 turn or so. Weird things can happen if you are on the fringe of being tight/loose. The light should reset in about 2 seconds of off time. And it should not be remembering your last mode for a 1/2 hour. If your threads are clean, I would contact 4sevens for replacement. Another thought... are you using a li-ion cell that might be too long? I've not seen a problem like that in a quark, just guessing.I have the regular Quark interface.
I am have problems keeping it from advancing modes when I turn the light off and then on again within 30-60 seconds.
If I wait a half hour or so, it will turn on with the same mode I shut it off with.
I have tried swapping clickies from my other Quark with the same problem.
This is really annoying and should have purchased the tactical interface.
