If you’re in the dark about some of the latest advancements in flashlight technology, here’s a quick summary.
Listen to BOB VILA ON NEW FLASHLIGHT TECHNOLOGY or read the text below:
For years, flashlights relied on bulky D-size batteries and bulbs with filaments. Today, two newer types of flashlight are gaining popularity—light-emitting diodes (LEDs) and fluorescents.
With no filament to burn out, LEDs are powered by tiny semi-conductors. Compared to traditional bulbs, LEDs draw a only a minuscule amount of power. That means they last much longer than the bulbs to which you’re likely accustomed.
Fluorescent lights are especially popular in lantern-type products. Thanks to their elongated shape, these fluorescents put out a lot of light and do a good job of illuminating larger areas—say, your dining room during a power outage. Fluorescents do take a lot of power, though, so you’ll want to keep plenty of batteries on hand.
