Question: Can the switch be "locked out" so it won't turn on if its packed in something like a backpack?
Document: It is an expensive flashlight, but it is worth the money. I have had no problems, it is very bright, and i have great confidence that it will work for a long time. The on button is a soft electronic button, not a mechanical switch. The only thing i did not like was the batteries. It uses cr123 batteries, witch are expensive. You can get them online for about 2$ a piece. Your flashlight will run a long time with them. 18650 batteries will not fit.
Very bright and compact for travel. Super quality. Always a fan of Maglite. Definitely recommended if you are looking for something this size.
This flashlight is amazingly bright for its size. It seems very well made, rugged, and is light to carry. The tail-switch is practical.
Quality flashlight. Excellent tail cap switch. Light output is awesome. I bought two (one for each of our glove boxes) for less than I paid for a Sure Fire. Mag Lite is stepping up their game with the Tac Lite
I have been a longtime user of Mag Lite flashlights from the 6-cell on down to the one AAA-cell for more than 20 years and have dropped them out of a semi, run them over with a car, dropped in a lake, and they have all continued working with only ever having to replace a bulb or lost the rubber button switch.
This Review Is Being Written After Over A Month Of Testing The Light, Not 20 minutes After Getting In The Mail.This is a very very bright flashlight at night time. But it is extremely unreliable, at times not coming on when you need it to. You have to hit it or shake it to turn it one sometimes. It is very strong and fully waterproof.
Received my light yesterday. Arrived very quickly and was in a cardboard wrap around the sealed plastic display container. It came with two CR123A batteries, a clip, and a tool for modifying the clip. I unscrewed the back, slipped in the two batteries, slid the clip over the Harrell, and screwed the back onto the barrel. I pressed the momentary switch for full light capability. I depressed and the light went off. I clicked the switch twice and the brightest setting stayed on.
And it's made in the USA.You can buy a Chinese light that is just as bright for less money but it won't light up every time you need it without shaking it, you'll have to cycle through all the silly lighting modes just to turn it on and off, it'll eat holes in your pockets or scratch your car interior and you won't have any customer support when the thing craps out on you.The light is amazingly bright.
i am very happy with this flashlight and it exceeds my expectations of operation and brightness. i also like the dim function that it has, and the momentary  function.
I am glad to see Maglite has caught up with the tac light world. I have their xl200 and it is great as well. I like the simplicity of the Mag-Tac.
