Poly Sapphire Clip Light USB by ASP
This is the newest in the evolution of the keychain light series where ASP designers have removed the metal in favor of a polymer case to provide the same light as before in a much lighter (16 grams or about half an ounce) rendition. This led light still employs the famous Nichia diode for its long burn time and bright output. Also retained is the USB charging of the permanent polymer battery and the Tri-ring clip used to attach the light to clothing or any convenient mounting location. The switch is still dual-mode where you can press down for intermittent activation or slide it to keep the light on longer. Package includes a micro USB charging plug that does require a USB port for charging.
The output of this flashlight is the same useful 20 lumens as in previous models. Runtime is 90 minutes on a full charge.
