E11-BK Waterproof Keychain Light, Black

;;This is the brightest keychain light I know of using a single AAA battery. It might be improved with a tailcap switch, but it would not be so compact. The included carabiner is a nice touch. Very good overall.

Extremely bright and small but has a flawed design. I have many twist on lights just like this bought over many years. The head that twists does not have enough threads (or is not long enough or tight enough) so that it is secure in the twist off position. The twist on head is the loosest and shortest on any light I have ever owned. I will not carry this in my pocket anymore because comes apart all the time. Also, since the head is so loose, the light comes on when the head is pressed in the twist off position. To make the light so that it never turns on, you have twist the head so that it almost completely comes off. I am still giving it 3 stars because it is still very bright and has a nice beam.

This is a great little light for the price. I have numerous AAA led lights in my collection, but for just over ten dollars, the E11-BK is one of the better lights I own.Measuring 2, 5/8 inches in length and a bit less than 1/8 inch wider than a AAA battery, it fits just about anywhere. The construction is solid, with an drop-in battery compartment and an o-ring to seal it. The o-ring is luminous, as is the ring around the lens - a nice touch, but any glow fades in seconds, making it somewhat of a novelty. The lens itself is plastic, with a hole drilled in the center, not all the way through, but enough to add some extra diffusion to the beam. I haven't tested it for water resistance; however, it should be fine in the wet unless submerged for more than a few seconds or at depth.The beam is very bright, with a slightly yellow light that stacks up against some of my single AA lights. I'm not sure it's a full 102 lumens, but it's bright enough to take care of any general lighting needs. Battery life is good and the beam stays bright for most of the battery life.Yes, it is made in and ships from China, but as I've said before, most of the lights you buy these days are. As long as it works (and it does work) I'll pay the ten dollars and enjoy having a couple of these small powerhouses in my pocket and go bags.

IT DOES NOT WORK. U have to push the head to light it up. it can not be regulated. and even when the light is off it drains your battery in hours

This is a screw based activation light, so, you turn it on by tightening it down all the way, this means there is a chance for it to turn on in your pocket or coming apart. I would prefer it if there was a bit more travel on the threads, so that the distance between activation and the light being secure to the body, and the light coming off the body was a little bit greater.The fact is uses AAA is great, where other pocket/keychain lights have those infuriating mint size batteries.

The only way to turn it on and off is to loosen and tighten the top. This is problematic because the top can fall off easily since it must be loosened for the light to go off. The other problem is that gunk builds up between the battery top and the light contact. You have to clean this regularly or the light will not go on.On the upside the light is very bright so it is great when it works.

Very good quality as far as I can tell. Nice and bright, great size for my key chain.

This is a great little flashlight I've had for a few months now. I wanted something small but bright for my key chain. I was concerned that it might come on while being carried around in my pocket, since it is a twist on, and would be dead when I needed it. But this has not happened once. Highly recommend this and it's a great price!10 month update: After nearly a year, this little light has been flawless. I don't use it much, but it is ready when I need it and really bright. The original AAA battery is still in it. I might get another one or two of these little gems for various places (like the other car's keys.)
