Types of Torches
This light is designed for tactical use, for example in the military or police force. Some models can be mounted to a weapon. They’re generally smaller than typical models, and emit a lot of light. A lot of models are made from aluminium for robustness.
These are small devices shaped like a pen. They’re often used in the medical industry to check areas of the mouth, throat and to assess pupil response.
Keychain and clip torches
These are smaller, more lightweight models which offer even more portability thanks to the keyring/clip. This means it can be attached to anything, from a set of keys to a rucksack – ideal for activities such as camping.
These feature a lithium-ion battery which can be charged once it’s flat, instead of having to be replaced. This reduces the cost of buying batteries and means they’re more environmentally friendly. Models that can be recharged are generally more expensive, but they often provide more light.
Right angle torch
This light is affixed to a headpiece, so it can still illuminate surroundings while leaving the user’s hands free. It’s ideal for outdoor activities such as caving, hiking and camping, as well as work environments to increase productivity and quality.
Powering the torch
