There are many uses for the Blackfire Compact Waterproof Clamplight, and one that illustrates its value is fishing at night. The light can clamp to your tackle box or the seat of your canoe. The 30-lumen beam is bright enough to illuminate your tackle. The light is easily operated by a push-button switch. Fresh included batteries provide a total of four hours of runtime, plenty of time to land a lunker. There won't be a problem if the light drops into the water, because it's IP67-rated waterproof, and it floats. Similarly, if it falls to the deck of the boat, no problem—the Compact Waterproof Clamplight is tested to withstand being dropped from up to 10' onto a hard surface. Not an angler? You'll find no end of other uses for this handy light at work, at home, or outdoors.
