I've got several of these Pelican lights in both the newer and older versions. We used them at work. They are only 45 lumen, but are pretty bright and the 4 AA alkaline batteries last about 4 hours. Uses a xenon bulb.
I also have a couple of these Streamlight headlamps which we also used. They feature 1 xenon bulb, 1 led, or 3 led in 12, 9, or 24 lumen. Run time up to 150 hours on 1 led. Head strap and 90* tilting head. Very handy.
We were given one of these Streamlight Task series as a safety award. They run on 3 AA alkaline batteries and have a run time up to 16 hours with 95 lumen out of 1 led. Nice handy light.
I picked up one of the older versions of these several years ago. Tikka plus I think is the name, the picture is of the Tikka 2 plus. Nice light weight and runs on 2 AAA batteries and has a couple of led settings. I don't remember the lumen but it is fairly bright. Only problem is the case doesn't want to stay closed and it pops open letting the batteries fall loose sometimes. Has red, blue, and green lens with it. I use it basically as a back up for emergencies as I have a little case that keeps it all together.
I have a Maglight metal D cell sized rechargeable flashlight with a halogen bulb that is bright but doesn't last long. I also have 2 of the 3 D cell Maglights that use regular batteries. Not real bright and short life. All of these can be used as a weapon as they are quite heavy. They are also bulky and get really cold or hot depending on the season as they are metal. I have them stored away and don't use them now.
