    Yea, they really should have added a 700ish level. I can say the light does not heat up at all on 320...runs great, staying surprisingly cool.

    700lm doesnt look twice as bright as 350 lumens, its not linear for the eyes

    True, think I have read it takes 3X. We are focused on a max brightness level without heating the battery and electronics.

    I sprayed just a hair of WD-40 in the head and tailcap/spring area. And cleaned N greased the threads. The light is now working very well on high and turbo. Can now see a noticable difference between the two levels...and no flickering and red light. Starting to like this bright little light. Also thinking the 38 lumen 46 hour runtime level could be very useful should the power go out for an extended time...as can happen occasionally down here in Florida from storms. Makes for a nice ceiling bounce room light level.

    Can it keep the high level forever without stepdown ?

    Apparently, according to this review. I have not tried it.
