>> What it is: A combination headlamp and lantern, with five LED lights. The lights range from 5 to 130 lumens.

>> How it works: The headlamp is affixed to a high-quality elastic band, with the two AA batteries and control buttons in a compartment at the back of the band, worn behind the head. When converting for use as a lantern, the headlamp portion is pushed into the separate lantern vessel, with the battery compartment being attached to the bottom, forming a single unit. The product also comes with the trademark Joby Gorillapod, which is three legs of plastic ball-and-socket joints that wrap around branches or table legs, or they simply stand on their own.

>> The good: For tent camping this is perfect. It gives you the walking-around light you need outdoors, plus the lamp you want inside the tent. With the entire 8.8-ounce unit closed up in the lantern compartment, this fits into a backpack pocket. The six light modes include two red lights for night vision. When using the red lights in the lantern mode, you have a real attention-getter if you’re trying to wave down someone for help. At the lowest setting, with a handy dimmer mode used by holding a button down, battery life is expected to be 72 hours.

>> The bad: On 130 lumens, everybody in the tent could read a book, but you would blow through those batteries in about 90 minutes. You may not be able to read a novel at lower settings, but you could play a portable backgammon game.

>> Cost: $60
