Coast KL10 100 Lumen LED KeyChain Light, Black

This flashlight is tiny. Fits perfectly in the coin pocket in my jeans. I work in IT in a manufacturing plant, and a lot of IDF's are in the ceiling with no lights. This flashlight brightens the entire compartment. When you have to dig through hundreds of patch cables to trace out a line to a wall drop in a pitch black room, you'll be happy when you have this in your pocket. It comes with a AAA Heavy Duty battery. I've always heard bad things about Heavy Duty batteries, so I've always used Alkaline or NiMH. The flashlight last 8+ hours on that single Heavy Duty battery. Because I have so many NiMH AAA batteries, I won't be purchasing any more Heavy Duty batteries, but if you don't already have other batteries, you can save a few bucks by just sticking with the same type the manufacturer includes: the Heavy Duty type. Before purchasing this flashlight, I never had anything small enough to fit in the coin pocket on my jeans, so I never used it. With that being said, the first time I washed my pants after purchasing the flashlight, I forgot to remove the flashlight from that coin pocket. I didn't realize what I had done until after I took the jeans out of the drying machine. Still works like a champ. No damage what so ever. I'm a flashlight junkie (power goes out often where I live), and if I didn't have so many already, I would definitely purchase this product again.

I've been using this guy for years and it's great. Bright, easy to use, takes a single AAA battery that'll probably last you over a year

This has to be the best keychain light there is. I wanted something small, bright and durable. And, I didn't want to have to remember to recharge it every few weeks or months, or forget when I last charged it- just wanted a simple AA or AAA batter I can find anywhere. The light itself feels durable, the focus doesn't spin easily so it won't turn on by accident. There is no button to fail, and it is small and bright! I've had a non-name brand cheap light and it failed rather quickly. I use Coast lights for work, and they all have been tremendous.

Bright and the recipient likes it!

Great little keychain flashlight that provides spot on light when needed for dim restaurants or other places when needed. It takes up little space and helps me find my keys in my overcrowded pocket.

A nice, neat little flashlight. About the same diameter as an AA battery and just a little longer. A good size for my keychain while using an AAA battery. Well made. Edit: I've now had this little guy hanging on my keychain for 15 months and it is still going strong.

Great little light to stash away and have on hand for emergencies, poking into small places, or just to use instead of messing around with your phone flashlight. Feels sturdy and well-made, and the light is very bright. This is the second one I've purchased.

Reliable flashlight that easily fits in a pocket. Battery is a single AAA, easy to replace when needed. For such a small compact light, it puts out a lot of light. Purchased this about 6 months ago, posting the review now, it's held up well.
