Flashlights Revisited
No gadget column worth its salt can ignore the burgeoning field of cool flashlights, so at the risk of repeating myself, I’d like to revisit the increasingly “enlightened” category of portable illumination.
The LED (light emitting diode) is actually a semiconductor — think transistor — that emits light, and it’s the future of flashlight applications. The reasons are simple. Your batteries last substantially longer, light intensity is greater, and the LED’s themselves last thousands of hours. The old incandescent flashlight bulb is a buggy whip by comparison! |
