- What is an LED?
LED stands for Light Emitting Diode. LEDs have several very positive characteristics such as they are virtually indestructible, are more efficient than traditional bulbs and never need replacing.
- How do flashlights work?
A flashlight is powered by batteries-they create an electrical current that flows through metal contacts and brings electricity to the lamp (light bulb) in the flashlight. A thin wire in the light bulb contains the element "tungsten", which glows when in contact with electricity, producing a visible light. This light reflects off the reflector resting around the light bulb.
- When I'm not using my flashlight, where should I keep the batteries?
Keep the batteries in your flashlight when it's not in use-that way, you'll have a working flashlight when you need it. If you don't use your flashlight for a long period, turn the power switch on and off occasionally, just to make sure the flashlight is still working. It's also a good idea to change batteries periodically to prevent battery leakage if you don't use the flashlight for long periods.
