I don't trust a lot of things that are branded "tactical" any more than I trust something that's branded "military grade". However most (and certainly not all) name brand "tactical" lights are overbuilt to the point that even I have a hard time breaking them. Case in point - my original Surefire 6P is still running strong; my son uses it daily. I upgraded to an LED lamp assembly before I gave it to him and that was after almost 30 years of use! My current daily driver is a Streamlight 1L-1AA and I'm sure it will out live me. But all my lights get used in mostly mundane ways; taking the dog for a walk, finding the bathroom while camping, etc.
