A dyno torch, dynamo torch, or squeeze flashlight is a flashlight or pocket torch which generates energy via a flywheel. The user repeatedly squeezes a handle to spin a flywheel inside the flashlight, attached to a small generator/dynamo, supplying electric current to an incandescent bulb or light-emitting diode. The flashlight must be pumped ...
A set of modern LED flashlights. A flashlight or electric torch (Commonwealth English), usually shortened to torch, is a portable hand-held electric lamp.Formerly, the light source typically was a miniature incandescent light bulb, but these have been displaced by light-emitting diodes (LEDs) since the early 2000s.
Solar powered lights need not be manually recharged as in the case of conventional battery operated flashlights. [3] Pollution from discarded batteries used in normal flashlights is eliminated. [4] Solar powered flashlights can be used in remote locations where it is impossible to find any source of electricity except for solar power. [4]
Tactical lights can be handheld or mounted to the weapon with the light beam parallel to the bore. Tactical lights can also serve as a non-lethal weapon , used to temporarily blind and disorient targets [ 1 ] or, in the case of a large handheld flashlight, to be used as a blunt weapon .
An acetylene gas powered lamp produces a bright, broad light. Many cavers prefer this type of unfocused light as it improves peripheral vision in the complete dark. The reaction of carbide with water is exothermic and produces a fair amount of heat independent of the flame.
ATS officers-in-training crew a 90 cm searchlight in Western Command, 1944. A searchlight (or spotlight) is an apparatus that combines an extremely bright source (traditionally a carbon arc lamp) with a mirrored parabolic reflector to project a powerful beam of light of approximately parallel rays in a particular direction.
Solar-powered calculators are hand-held electronic calculators powered by solar cells mounted on the device. [1] They were introduced at the end of the 1970s. [2]Amorphous silicon has been used as a photovoltaic solar cell material for devices which require very little power, such as pocket calculators, because their lower performance compared to conventional crystalline silicon solar cells is ...
The term "blowtorch" applies to the obsolescent style of smaller liquid fuel torches. Blowtorches are typically a single hand-held unit, with their draught supplied by a natural draught of air and the liquid fuel pressurized initially by hand plunger pump, then by regenerative heating once the torch is in operating state.
