The Princeton Tec Eco Flare can be set on a constant LED burn for use as an area marker for night time identification or as a personal locator light. In flashing mode, a single red Ultrabright LED makes a great marker beacon or saftey light as it pulses for up to 500 hours. A great light for any outdoor enthusiast’s equipment bag and a vital tool for any night diver!

Overall, this flashlight is worth the price. Simply constructed, very durable, and water tight.
It was smaller than I expected, only about the size of a Pez dispenser. It's a good size to hang on your shoulder, or from the ceiling of a tent. It even comes with a lanyard to make it easy to do this. Backpackers who want to minimize the weight they carry as much as possible will probably like the size, unless they need a real powerful spotlight.
It comes with 2 bulbs: a white "Krypton" bulb and a red LED bulb. As far as I can tell, the Krypton bulb is just a kind of LED bulb.
The white bulb works well if you need something to give off just enough light for you to see whatever is right in front of you, but it's not bright enough to illuminate a path if you're moving. It's clearly not meant for this purpose anyways though, because it doesn't have an ordinary lens. Instead, the bulb is surrounded by a rubber cone that sends the light out in all directions. Some of the other Princeton Tec flashlights have a removable cone with an ordinary lens underneath. This one has just the cone.
The red LED light, which always blinks when on, is good if you want something to make yourself visible to people around you. You could hang it on your backpack if you're bike riding at night, for example.
Apparently, divers hang it on their shoulder when they go under water.
The bulbs are quite difficult to interchange, however. You need pliers to pull a bulb from its housing. So you won't want to have to switch bulbs frequently. Better to just stick to the bulb that you are going to need most often.
