The first torch light was introduced in 2009, and the name was ANSI FL1 standard torch light. During launching the torch light was tested in different stages and phases. The testing factors and performance measuring factors are mentioned below.
Output of Light
The light output is measured in lumens. In this factor we measured the intensity of the light outputting from the torch light. For checking it out the new batteries, and in the torch light, and run it on the highest brightness. The standard torch light always shows the multiple settings of the torch light, and these settings help in judging the intensity of the light easily.
Measure Beam Distance
The distance of the torch light is measured in meters because it is the length of course. In the beam distance we measure how far the shining of the torch light can travel, or spread. The torch light shines diminishes to the equal distance of the light from the full moon. The full moon light is considered as the standard illumination for careful and safe outdoor travels.
Rechargeable Torch Light
One more important thing you need to consider is whether the light is a rechargeable torch or not? If it is rechargeable then good to go, because you don’t need to spend much money on the purchasing of the batteries every time. In case if the light is not rechargeable then of course you have to buy the battery for everytime and it may cost you money.
Run Time of the Light
The key factor of estimating the performance is the backup timing, the backup of the light measures in the hours. That how many hours the torch light can give you light in the darkness. The best way of measuring the battery timings is, check how many cells of the battery dropped in the first hour. This is the easiest way to measure the battery timings.
Is it Waterproof?
The torch light should be waterproof, because if it is waterproof, then you can spend it with a long life. I think it is the important factor you should see before purchasing the torch light. Because sometimes the water can drop on the torch light and it may cost you money. So it is good to go with the torch light if that is waterproof.
