Off can be selected from any mode after about 10 seconds. The build-quality and and brightness are decent. The only thing negative I can say about this headlamp is that the light is slightly bluish with about a 7000 K color temperature and about 0C tint on the Cree scale. Not really off putting, and a muggle probably wouldn't even notice. A good headlamp to throw in a toolbox or the trunk of a car for occasional use. I would switch out the alkaleaks for Ni-MH or primary lithium batteries in this scenario.
No problem. BTW, I normally do not buy store bought lights. Unless 1000 lumens or more being my standard. The 2 pack USB powerbank/flashlight combo looked nice with silver color.
Yeah, I saw them at my local HD yesterday. The 4000 mAh capacity is on the low side for powerbank this size (2x18650), but not bad for the price, I guess.
I also wonder what they did to get 200 extra lumen out of that Defiant light. The one I got last year was rated 1,000 lm only.
