What are Battery Powered Led Lights?
Battery powered led light is a type of lighting device which uses batteries instead of electricity to produce light. These devices have been around since the 19th century, but they were not widely used until the early 20th century when it became possible to cheaply mass produce them. Today there are several types of battery powered led lights available. Some of these include:
LED (light emitting diode) – A semiconductor device that emits light when voltage is applied to its terminals. LEDs are very energy efficient and produce less heat than incandescent bulbs or fluorescent lamps. They are inexpensive, durable, long lasting and last a lifetime without needing replacement. LEDs are found in many household items such as flashlights, computer monitors, street signs and even some toys!
CFL (cold filament halogen) – A type of LED that produces light only at temperatures between 0°F and 140°F (-30°C and 60°C). CFLs are generally found in kitchen appliances such as coffee makers, ovens, stoves, etc. They use low power consumption and do not require any special cooling system. Most CFL bulbs will work with just one bulb.
Incandescent – A type of light bulb that produces light when an electric current passes through a thin filament wire which is located inside a high intensity inert gas so the filament does not burn up too quickly. After the filament gets energized it produces heat which then makes the filament white hot which then produces light and this cycle keeps happening until the electricity is shut off.
One of the major benefits of battery powered led lights is that they use power very efficiently. This means that you can use one battery powered light for much longer than you could use a standard incandescent or halogen light. As an example, if you were to set up two identical standard light bulbs, one that uses electricity and one that uses batteries, the battery powered light would produce the same amount of light or perhaps even more than the standard light bulb that uses electricity. When you use battery powered lights, you also do not have to worry about extension cords or having to find a close electrical outlet.
Since the light is also much thinner than the standard incandescent or halogen lights it can fit into much tighter places and it is perfect for working on equipment, making repairs or even setting up a makeshift mini-stage for a puppet show! (For greater flexibility in positioning the light, some battery powered lights can be mounted onto a ball-joint. The base of the light can then be screwed onto a tripod to make it easier to aim the light in one direction or another).
Another benefit of battery powered lights is that they do not produce a lot of heat and are much safer to handle when working on live electrical equipment. For these reasons they are commonly used by professional electrical technicians and electricians who often work on or around live wires. These lights are also great for automotive work or doing repair work in hard to reach areas where an electrical outlet is not nearby. Just make sure that the batteries you use are top quality (such as Duracell, Energizer, Panasonic or Kodak) and that they are installed properly.
It is also a good idea to keep a few spare batteries on hand so you can switch them out in case some of the batteries accidentally get drained during an extended period of use.
While the cost of these lights might be higher than traditional incandescent or halogen lights they typically last much longer and save money in the long run. If you are using your light for a task that is done only occasionally like an attic or storage room then you may want to consider plugging it in so you don’t have to worry about changing batteries or possibly forgetting to change them. However, if you anticipate that you will be using your light on a regular basis (such as at the kitchen table while doing homework or reading) then battery power is definitely the way to go.
Battery powered lights are available in many different styles and sizes to accommodate whatever purpose you have in mind. While these lights might not be appropriate for every situation, if you think they will come in handy at some point then it is probably a good idea to keep a few on hand because you never know when the need may suddenly arise!
Battery powered lights are also an excellent choice for people who do a lot of camping or spend time outdoors. They can serve as practical flashlights in case of an emergency (like a power outage), provide warmth and comfort when reading at night or even act as a portable mini-stage for impromptu puppet shows on those long, rainy days. The possibilities are endless.!
