A flashlight a person’s savior when there are blackouts or power failures. They are of great help for emergencies during night. They are best sources of light when there is interruption in power supply or, where lighting is required. Installation of flashlights is mandatory at certain places like schools, hospitals and other places to light up the places in case of power shortage or blackouts. Flashlights are needed everywhere right from homes and offices to hospitals and schools. Incandescent bulbs are used in older models of flashlights, but the latest ones use LED flashlights for lighting. Today many people are going for LED bulbs, as the awareness for energy-efficient and greener technology is growing at fast pace.
Buying flashlight is definitely making big decision, especially big ones that need to cover huge areas like schools and hospitals. But how do you know what you have selected is the right and best choice for your requirements. Flashlight is an investment whether it is purchased for home or hospital. A little knowledge of working and concept of flashlights are required to decide on the one that best suits your requirements.
If you are planning to buy a flashlight then you need to consider two basic things, intensity and brightness apart from price, color, shape and size. Candle power is unit used for measuring brightness of the flashlight. But simply buying flashlight because it is offered with highest candle power will only result in early draining of battery power. Buying a flashlight based on the lumens is definitely considered as a better buy.
Buying high lumen flashlights is more advisable than high candle power flashlights. High lumen flashlights are superior to high candle power flashlights, you can understand it only when you know what exactly lumen is and on what basis it is calculated. Lumen is a measure of light output from any light emitting device like flashlights. In other words it is a standard unit to measure light spread over a specific area. Brightness is spread over equally in large areas when lumen power of a flashlight is high. LED bulbs are reputed for higher lumen flashlight output than any other filament bulbs making them energy- efficient. Lumen/watt rating of LED bulb is high resulting in higher efficiency and low power consumption. Hence, when looking for a lumen flashlight, you need to look for one with more lumens to get that perfect and evenly spread brightness in large areas.
Lumen flashlights are available in various models in the market where number of lumens in each flashlight differs with each model. Number of lumens required by you in a flashlight depends on its usage and area that needs to be lighted. Common range of lumen flashlights are 10 to 100.Places that need minimum lighting can use 10 lumen flashlights, little darker places where more of brightness and intensity is required a 30 lumen flashlight is good enough, if you are interested in lighting distant areas then a 100 lumen flashlight is required. Using LED lumen flashlights can increase battery life by three times where bulbs need no replacement for life time. You can use flashlight for hundreds of hours before batteries get drained out and needs to be replaced. These flashlights are not only energy-efficient, but also release less amount of heat when compared to flashlights with incandescent bulbs. Hence it is sensible to buy a lumen flashlight with high lumen watt rate to increase life of battery.
