Question: So, this flashlight needs 3 batteries?
Document: Look, I can't tell you how many lumens this puts out, or how many I needed to satisfy my needs, but this little (3 inches long) light is brighter than two Maglites, my Coast HP6, a Smith and Wesson LED that is just plain terrible, and even a one that uses C size batteries! I can't explain it. It just works.I needed a flashlight that could light up areas behind cabinets, the water heater, and the AC.
Lighting EVER Adjustable Focus CREE LED FlashlightMy daughter wanted a bright flashlight for camping in the woods. I wanted a flashlight that had certain features. 1) It had to be very bright and lightweight. This flashlight weighs 1/15th the weight of my 15 year old 3 D-cell Brinkmann. 2)It needs an adjustable zoom. It has a very good zoom. 3) It need to accept regular sized batteries. It uses 3 AAA-cell batteries.
Pros: Adjustable focus, decently bright, uses commonly found AAA batteries, build solid and the on/off switch doesn't feel cheap.Cons: It needs more resistance with the adjustable focus, too easy to move it inadvertently.You really can't go wrong at this price point. I've ordered 3 total to keep in the car and around the house.
WOW ! This little LED flashlight outperforms my old and very big 2 D cell battery flashlights - and it does it with 3 AAA batteries.
I love this flashlight. It's small, compact, lightweight, durable, and very bright. It uses 3 AAA batteries and features an easy-to-use adjustable focus. At this price, it can't be beat.
Best flashlight on amazon for the price. Zoom is very clear. Very strong LED and comes with all 3 AAA batteries. My friend had a recent blackout and I came over (keep this in the car) and everybody commented how bright it was.
i couldn't really believe how nice this little flashlight is being so cheap. This thing is pretty freakin bright while using only 3 AAA batteries. The zoom feature is one of my favorites. it zooms in so far that you can actually make out the shape of the LED. Pretty nice and compact.
Using only 3 aaa batteries, this thing throws a beam that will make you wonder why you'd want any flashlight that's more powerful (trust me - you will). It will also zoom out and cast a flood that's very impressive. What it DOESN'T do is strobe or change brightness, even though the description says it will. You know what? I'm giving it 5 stars anyway.
Besides it's a variable beam adjustment from one point to another, there are no 3 selections. Also the description covers the beam adjustment by stating &#34;Adjustable beam focus&#34;.Still, I love this flashlight and will buy another when needed. I may even buy some rechargeable batteries for it if I use it enough.
I received the flashlight batteries included, for once. That was nice for a change. But nothing compares to the brigtness of this little flashlight. My wife was coming home late from work as she does 2 or 3 times a week. I went out to meet her. She was a half a block away. I shined the flashlight at her and it was blinding. Turned off the lights in the house and turned on the flashlight, it was like a flood light.
Answer: yes
