A vital part of any outdoor enthusiast’s equipment bag, the Eco Flare can be set on constant, high-output, incandescent mode for use as an area/personal locator light, or on flashing, red Ultrabright LED mode for low-visibility, dark nights. The Ultrabright LED will burn in excess of 500+ hours on 2 AAA alkaline batteries. The Eco Flare can also be attached to your dog’s collar for easy identification in low light conditions.
These are useful little lights - I presume they are designed as a marker light for diving but we use them for marking the bow and stern of sea kayaks for night paddles. They are also handy around camp - we hang them from trees to provide some general light and they will illuminate a small tent. We have found them robust and watertight at least for surface use.
The description Princeton Tec gives is a little hard to understand. The light arrives with a red flashing LED installed and a continuous white LED. You will have to pull out the red LED and insert the white one. They are hard to remove - I used pliers - so this is a light where you will choose one or other LED at home, not something you can easily switch in the field. Since the dimensions are standard you could use any color LED you wanted.
This product replaces the Princeton Tec Sport Flare, which was generally a superior product let down but its thirsty and unreliable bulb. A Sport Flare with the bulb replaced by a Dorcy 3V LED is an excellent light but seems to be out of production. (Posted on 7/30/14)
