You know what they look like. You probably have some in your house. Maybe your strings of Christmas lights this year were lit with them. Maybe you use battery-operated LED lights in your flashlight. But do you really know what LED lights are?
LEDs, or Light-Emitting Diodes, are the Bionic Man of lights. They use scant energy to create more brilliant light, and they have remarkable staying power. Just as with incandescent bulbs, there are LED lights that screw into a base to be powered through a cord, and then there are also battery-operated LED lights. If you’ve seen LEDs, you’ve probably noticed how much brighter and whiter they are compared to incandescent bulbs. That stark light is the product of a phosphorous coating and metal conductor. There’s no need for an incandescent filament, which is the hair-fine wire that heats up to the point of glowing.
To explain what we mean by remarkable staying power, consider this: To get 200 hours of light from your average flashlight, you can expect to burn through 12 incandescent bulbs powered by 234 AA batteries. But you’d need just one LED light and 6 AA batteries to do the same job. The energy cost difference? Try $175 for the incandescent bulb versus just $7 for the LED. Now, that’s remarkable.
Rayovac offers a bounty of battery-operated LED lights, from glow sticks to reading lights. Kids tend to dig our magnetized LED party lights, shaped like little eggs and able to flash an alternating rainbow of colors. Grown-ups tend to enjoy our LED Floating Lantern, which can blast its shine up to 226 meters away. Last but not least – and probably the most important thing to keep on hand in your house and vehicle – are our LED flashlights. We’ve got tons. Because of the remarkable staying power and longer life of battery-operated LED lights, an LED flashlight is just the kind of light you want to have in your emergency kit!
