It's the time of year when weather can turn ugly in a hurry. That means power outages — and the need for reliable emergency lighting. While LEDs aren't quite ready to replace incandescent or CFL bulbs around your home, their highly directional nature makes them perfect for flashlights.
LED flashlights are green, too — in addition to lasting thousands of hours longer than conventional bulbs, they'll coax up to four times as much light from a set of batteries. You'll cause less waste with conventional batteries, and go much longer between cycles using rechargables.
While LED flashlights cost more than their traditional equivalents, you'll quickly recover the investment. Or upgrade your current flashlight's bulb with an LED replacement.
