A flashlight (often called a torch outside North America) is a portable hand-held electric light.

The source of the light is usually an incandescent light bulb or light-emitting diode (LED).

A typical flashlight consists of a light bulb mounted in a reflector, a transparent cover (sometimes combined with a lens) to protect the light source and reflector, a battery, and a switch.

These are supported and protected by a case.

The lumen (symbol: lm) is the SI derived unit of luminous flux, a measure of the total quantity of visible light emitted by a source.

Luminous flux differs from power (radiant flux) in that radiant flux includes all electromagnetic waves emitted, while luminous flux is weighted according to a model of the human eye's sensitivity to various wavelengths.

Lumens are related to lux in that one lux is one lumen per square meter.

A headlamp (known as a head torch in the UK) is a light source affixed to the head for outdoor activities at night or in dark conditions such as caving, orienteering, hiking, skiing, backpacking, camping, mountaineering or mountain biking.

Headlamps may also be used in adventure races.

Headlamps are often used by workers in underground mining, search and rescue, surgeons, and by other workers who need hands-free lighting.

The ampere (SI unit symbol: A, dimension symbol: I), often shortened to "amp", is a unit of electric current.

In the International System of Units (SI) the ampere is one of the seven SI base units.

It is named after André-Marie Ampère (1775–1836), French mathematician and physicist, considered the father of electrodynamics.

Eye protection is protective gear for the eyes, which comes in many types depending upon the threat that is to be reduced.

The threats can be particles, light, wind blast, heat, sea spray or some type of ball or puck used in sports.
