– The incandescent flashlight: a traditional model that tends to disappear from shops because of its mediocre performance and its progressive ban by the European Union.
– The halogen torch: with lighting that can cover hundreds of meters, it also has a longer life than the incandescent.
– LED torch: the latest technology that offers both more energy-efficient lighting and more powerful (up to 1 km) than the other two solutions, while offering a much longer battery life (up to 10 hours).
– Power source: batteries, batteries or photovoltaic cells. Battery and battery power is by far the most widespread, while solar lamps are still relatively rare even though they are becoming more popular. Rechargeable batteries have a better range and are more convenient in remote areas.
– The color lighting: halogen lights have a warm tint pulling orange, while the LED lamps provide a rather cold white.
– The width of the beam : a wide beam is recommended to illuminate correctly at a short distance (the cellar of the house, for example), whereas a narrow beam has a long range and corresponds more to an external use.
– Light output: 10 to 1,000 lumens. The lumen is the criterion for selecting the LED lamps which now replaces the watt (incandescent bulbs).
