Even though headlamps are an option that’s on the rise, flashlights are still the best source of light for many different needs – each time the strongest portable beam is needed, when dexterity and light precision are priorities and for the purpose of signalling, to name a few. That being said, technology developments have led to high battery efficiency and more convenient, lighter and brighter flashlights that can serve their purpose for a long time.
The Various Uses of Flashlights
It is a challenge to narrow down the uses of flashlights since they are so many. First of all, there are types that are great for general use. Size and performance are not an important factor here, as long as the light is readily accessible at all times. This is for those instances when you would use it to throw light at an item or person for a short period and without any urgency. Next, there are everyday carry flashlights (EDC). These are supposed to be small and practical since you need to have them on you at all times.
And the last and probably the most useful type is the wide beam flashlight – a tool used for work, outdoor recreation, searching and of course, if by any chance you find yourself in danger these can be real lifesavers. A wide beam flashlight has different brightness settings, a great lumens output, and it is a highly resistant, waterproof type of flashlight. When you are out and about – camping, hiking, fishing and whatnot, the wide beam flashlight should be on your must-bring list. A lot can happen in the great outdoors, and whether you need it to find someone, something, to light your path or to signal that you needs rescuing, having it on you can be of great help. Moreover, besides for outdoor adventures, a wide beam flashlight can come in handy during blackouts or natural disasters too.
Important Flashlight Performance Data
- Light Output – This feature is measured in lumens. What it actually shows is the intensity of the light coming out of the flashlight itself, on the highest brightness mode powered by new batteries. Light output ranges from modest 20 lumens (ideal for book lovers who read at night) and go up to 3500 lumens for wide beam flashlights (terrain and search needs).
- Beam Distance – Measured in meters. This feature shows how far the light will shine before it diminishes to the equivalent of a full-moon-light. This distance can vary and can be controlled with the brightness setting most flashlights have.
- Run Time – Understandably, this is measured in hours. It measures the time needed for the light output to drop to 10% of the rated output on new batteries. There are models that have a light output which over time decreases or in some cases remains fairly constant and then suddenly decreases.
- Impact Resistance – This is again measured in meters. The impact test entails the flashlight being dropped six times onto concrete at the rated distance. The goal here is to make sure that the light remains completely functional after some accidental drops.
