Great light, but like any surefire you need to keep extra batteries handy. I keep an extra 6P in my range bag and the Z2 combat light on my duty belt.

I have been using Sure Fire for about 15 years and absultely love the brightness of the light and the size. I don't need a bulky carrier for it. The only I have a problem with is the batteries. It uses more battery power than I care for, especially for batteries that are nearly $10.00 each.

THis is a great light. I have several of them, and one mounted to my rifle. They are small light and reliable. I would recommend this light to anyone who is looking for a small light to carry on thier belt with them all the time.

Great product as with all Surfire products. Bright light, durable and is a primary light on my belt. I don't like the idea of having to carry spare bateries in my bag, but this thing will light up any place you need to see. I now they make a rechargeable version, but it is too big to carry as a secondary light.

Great light, but better for use in 1 or 2 second bursts, rather than letting it run continuously. I upgraded mine to 120 lumens, and if you thought 65 lumens was bright, wait until you see what nearly double that looks like in a dark room--scorchingly bright even in the midday sun.

I have the 6P defender with the strike bevel on the front of it. It is the best light I have ever used. It's a lot brighter than most lights its size and the strike bevel is great for pressure points to get compliance.

Very pleased with everything but the battery cost!

I got my Sure Fire in Iraq last year. After packing a 'low battery usage' led flashlight for a few months, I couldn't believe how much better this light is! It does have it's limitations, mostly the battery life is significantly less than my old light. But for the intermittent needs I had, this light was powerful and bright, exactly what I needed.

put out a bright light

I have this light and keep it on my duty belt.This light is bright but it does love to eat batteries.also does anyone know if they make the kit to change this light over to a LED bulb??????

I checked on the 6P LED conversion kit at surefire.com. They do have the kit, however, it costs as much as a brand new 6P LED light! Go figure...

This is the perfect back up light, small and tough. Using a disposable battery was not what I had in mind but with the lithium the shelf life was amazing, so you didn't need to worry that it would die before you needed it. This light has saved my a** on more than one occasion, when my duty light would die, you know it will only do so when you really need it, this light would get me through the shift easily. Call me paranoid but I would replace the batteries after needing to use it for any extended time frame. Find a wholesaler online and you can pick them up for less than a buck each (CR123 also work in some cameras so shop by that designation not whats its labeled for). Treat it like your back up firearm, it may just save your life.

This light is compact and extremely bright. The battery life is an issue but can be improved considerably by converting it to the LED bulb. The conversion extends battery life out to nearly 12 hours. I carry one on on and off duty.

Very dependable flashlight.

dependable & bright. have used it attached to the rail on my 45, 9 and 5.56/223 AR. No issues well built
