I'd bought an Eveready 2-AA flashlight with lots of lumens. I wanted a quick flashlight for around the house, but also outside where it's pitch black at night. That flashlight routinely went through batteries, even when it wasn't being used, for whatever technical reason (probably a smart switch), and would suddenly die, right when I was out in that darkness. I did some research, and found that I don't need all that many lumens -- I read some articles that compare brightness. I also wanted a rugged, well-made, hopefully American made flashlight, and came upon this dual light. It uses 3 AA batteries, but I don't care! It's great! It's only slightly larger than a typical 2 AA flashlight, and easily fits in the hand. It comes with a wrist lanyard as well. I reach for this flashlight constantly, because with the side light (each light has its own switch), I can use this like a quick work light. It doesn't roll when I lay it down, it's bright, and the light faces the work area, not my eyes. Plus, I can stand it on it's front face, and that side light still is perfectly bright. Then I took it outside one night, to walk around the property. With no moon, I can't see anything at all. I turned on the front facing light, and it was amply bright enough to see where I was going, what I was looking at, and quite far ahead. Then I added the side light -- you can turn on either light (front or side), or both at the same time. Just as others have said, the side light, pointing down, lit up a nice path for walking, while the front light lit up the yard. Really a nice light! I don't need waterproof, and don't go out in the rain. I just need a work light in the house, a quick light for under cabinets, and something when I go outside. This perfectly meets all those needs. I haven't had it long enough to know the battery life, but it's already WAY longer than that "smart" Eveready. I'm just using regular AA batteries, but if I put in lithium, I'm sure it would be even brighter.
