The review today is the Bundled with 10 Black Flashlight Keychain 22000mcd (Black Flashlight Keychain 22000mcd 10-pack), acquired na DealExtreme, which came in one of packets that arrived last week. I decided to buy them after I received one of the toast DealExtreme in a package various products. They are mini-keychains, the size of just two Batteries 2016 that carregam. There is a very bright white LED (22000mcd) tip, that lights up when you press the center of the top or when we turn on a small switch (to keep you connected and keep your hands free). All 10 came running smoothly, are great to put on keys and always have a mini emergency flashlight handy (at least whenever you're walking with a key, which is not unusual).
The user Bombyx made some comments in the forum on the DX be no resistor to limit the current in this keychain, which causes the LED to receive more current than would, warming and decreasing your very life, and decreases the battery life. He proposes to use only one battery, which makes the least bright light, but increases the life of the battery and the LED. Use it only for a few seconds also minimizes this problem, it does not heat up as much time LED pro, therefore recommend that it be used only when necessary even, for short periods, without using the switch that keeps you connected. For long tasks that are not emergency is better to seek a better flashlight.
A DealExtreme also has other colors besides black: translucent white, Translucent Blue, translucent purple, Green tranlúcido, Red tranlúcido and yellow tranlúcido. There are also options of other light colors: Translucent Blue (light blue 1300mcd), Translucent Yellow (yellow light 1400mcd), Red tranlúcido (with red light 1400mcd) and Green tranlúcido (with light green 1400mcd). There is also a version with ultraviolet light (UV) and a version in which the light is focused at a single point. All links are for packages 10, but there are also packages with two individual keychains.
