LED flashlights are a newer, more efficient and more practical type of flashlight. Despite some disadvantages of this technique, the pros seem to outweigh the disadvantages. Downsides of LED flashlights that was when they first came on the market has declined as production becomes more cost effective and LEDs become more powerful.
Long Battery Life
A LED flashlight batteries last much longer than the batteries in an ordinary flashlight, which is an important factor when buying a flashlight for emergency use. Flat batteries will not be of much use in an emergency. A LED flashlight provides battery life measured in tens of hours rather than just hours of an incandescent flashlight provides. See waterproof headlamps reviews.
Long-lasting, Bright Light
The bulb in the LED flashlight lasts many times longer than the incandescent lamp in a traditional incandescent flashlight. The life of the lamp itself is over 100,000 hours, which means you never have to functionally replace it. Brightness is also an advantage. The light quality from an LED flashlight is usually much more intense than the light you’d get from an old flashlight.
High Initial Costs
The initial cost of an LED flashlight is more than other flashlights you normally see in the store. This cost can be frustrating or offensive if you plan just to use the flashlight in an emergency. If you use the flashlight a lot, making life cost less of a factor.
Limited Lighting Distance in Older Models
Some models of LED flashlights illuminate longer than traditional flashlights. However, older-model LED flashlights do not illuminate objects as far away as traditional flashlights going. Lighting distance could be problematic if you need a flashlight in an outdoor situation where you are trying to see as far away as possible.
