    How do torches work?

    Today most torches, or flashlights, are designed to work with LED energy efficient bulbs and are battery powered, which can be either disposable or rechargeable.

    Standard Alkaline batteries are an affordable option normally providing between four and ten hours of light on one set, while lithium-ion rechargeable batteries will last till they require recharging.

    The different parts.

    • The outer casing / body can be made from materials like aluminium, plastic, or steel providing protection for the internal parts of the torch. The torch casing may include a textured surface or grips providing you a secure hold.
    • The Torch bulb, when switched on, provides your light source. Torches are normally supplied complete with the bulb which can be a standard incandescent bulb or an LED (light emitting diode) bulb. LEDs have a longer life span and are more energy efficient.
    • The torch Reflector is normally found at the back of the torch bulbs / LEDs and designed to direct and focus the light beam. Depending on the torches design and specific use the beam can produce a floodlight or spotlight light beam.
    • The torch lens or cover protects the bulb / LED from damage helping to distribute the light. Some torch designs have adjustable covers and lenses allowing you to change the pattern of the light beam.
    • The torch battery compartment is where one or more batteries are placed and accessible by a cover or screw cap. Battery compartments are designed to hold the exact number of batteries required to power the torch. Rechargeable torches will include a battery recharging port or a docking area for recharging the internal batteries.
    • Every torch will include a power button, switch, or twist mechanism to turn the torch on and off.

    The features of a torch may vary depending on the specific use the torch was designed for. It can be for everyday general-purpose use, industrial use, tactical use within security or for outdoor activities.

    Torch performance

    What do you expect from a torch or flashlight? Do you want a torch for everyday domestic use or is it needed for a specific purpose? Always consider what your specific needs are and what you need the torch to do as different applications may need various lighting solutions. Some models provide special features like adjustable focus, coloured LEDs and offer various accessories like diffusers and filters.

    Light Output

    Light output is measured in lumens (lm), which is the unit of measure of the total amount of visible light produced by a light source. Lumens measure the brightness of the light so the more lumens produced the brighter the light produced will be.

    LED (light-emitting diode) lights are a popular light source offering greater energy efficiency, better battery consumption, increased brightness, and better impact resistance than incandescent light bulbs.

    Torches

    Beam Distance

    The beam distance or throw tells you how far the beam of light has an effective reach. This is an important consideration when a torch or flashlight is used in applications where long-range visibility is vital.

    Beam Pattern

    The beam pattern of a torch explains how the torch light spreads the produced light. Some standard patterns of light distribution are, spotlight (focussed narrow beam), flood light (wide light distribution) plus adjustable light allowing you to switch between different light modes.

    Run Time

    This refers to how long a torch will operate continuously on a single set of batteries or a fully charged re-chargeable battery. A manufacturer will supply the runtime information for differing brightness levels.

    Impact Resistance

    Measures a torches ability to withstand drops and not cause any damage. Lights that have been impact tested have normally been dropped six times onto concrete at rated distances. A torch or flashlight that has been designed for robust and harsh environments will normally have a higher impact rating than standard torches.

    IP Rating

    IP Rating is a short description for Ingress Protection Rating which determines the level of protection an enclosure, in this case a torch, provides protection from intrusion by external environments like dust, dirt and liquids (levels of water resistance).

    Water resistance is important of the torch flashlight is used outside in all weather conditions, or in and around water it is rated using the IPX rating system. An IPX4 rated torch flashlight is splash resistant from all sides. IPX7 is resistant to temporary immersion withstanding up to 30 minutes at a depth of 1 m. IPX8 resistant to submersion up to 4 hours at a specified depth.

    Power your Torches

    AA batteries are one of the most common types of swappable power cells in circulation today. They are what we picture when we think of the standard size and shape of a replaceable battery.

    AA batteries are used in single cell devices or combined into pairs (or larger multiples) for powering larger but still portable consumer electronics. A versatile battery and available worldwide as rechargeable and non-rechargeable.
