behaves with flashlights as they are with firearms: You should always at least one with you. The Torch Run is (still) not regulated or proven criminal. But to be not overwhelmed by the choice, here are some hints for purchase.
LED or xenon?
While a few years ago the choice between the LED module and xenon Glühfadentechnik had to be made, can now be fully advised for most applications to LED lamps. LEDs have overcome the teething problems at low light output, and inadequate heat dissipation.
The LED technology (Light Emitting Diode) In comparison to conventional bulbs much brighter, with smaller dimensions and weight. Light emitting diodes are microstructure solids and completely immune to shocks. They hold about 1,000 times longer than conventional bulbs and consume produce in relation to the luminosity less heat and less power.
light output and lifetime
An essential element of a light bulb is the light output. It indicates how efficiently the electric power (in watts) in a luminous flux (in lumens) can be transformed. Measurement of light output are lumens per watt. Under incandescent light, a large part of the supplied electrical energy is converted into heat. This is an advantage of the LED. They work without filaments and therefore generate much less heat. The operating principle is more efficient than incandescent bulbs in the area. The light output, ie the efficiency of an LED about three years ago was 50 lumens per watt. High quality modules achieve a yield of 100 lumens per watt. This compares to achieve about 15 lumens per watt bulb and a halogen spotlights about 30 lumens per watt. The life of an LED is typically 50,000 hours. Sometimes up to 100,000 hours. (A halogen spotlights about 1,500 hours) The life of an LED is caused by: temperature and electrical current. The higher the temperature, the shorter the lifespan.
The price segments
is not advisable from the purchase of an LED flashlight at the hardware store. Even if the price is enticing about 10 €, it is in most cases to be bought inexpensively Clearance product of an outdated technology.
the other hand, available for the amount of 50 to 80 € a high quality product of the latest generation. The chinese Fenix won in recent years, substantial market share. Currently, a complete series of Fenix flashlight on the market. These solutions are for all purposes to the right lamp. And at an unbeatable price-performance ratio.
little deeper you have to reach into the bag, if one is to sure-fire quality . Equip Lamps of the U.S. producer enjoy surefire for over 30 years an excellent reputation for indestructibility.
Fenix LD10
The Fenix LD10 is one of the smallest representative of the series. It is powered by an inexpensive and readily available AA battery. With the belt clip and the supplied cordura belt holster it is recommended as a companion for every day. The LD10 has a total of six light modes. Two of them in the turbo mode and four in normal mode. Clicking the negative switch allows light but no moment.

Fenix TK12 Fenix TK12 The
is typical for the compact class. It is larger than the LD10 and is powered by two CR123A batteries. When purchasing a lamp should not be forgotten that the security of supply of CR123A batteries in weak infrastructure regions of the world is not always guaranteed. Respectively. the cost will be high. The TK12 has a pressure switch for intermittent and continuous light. By turning the bezel can be set three different modes.

Fenix TK 45
The TK 45 not only sets new standards in terms of light output, but also for their futuristic design with the 3-way lamp head. Like all other Fenixlampen the TC 45 has a splash-proof, mattschwarzeloxierten aluminum body. Unlike other lights of Endkappenschalter more than two side-mounted function keys.
According to the manufacturer, the three R5 Cree LED modules have a total luminosity of 760 lumens. Fed, the TK 45 overnight inexpensive AA batteries, but can optionally be operated with batteries. The lamp has multiple lighting levels 8-760 Lumen, and various flash functions. It weighs about 500g and is 200mm long. The body has a diameter of 45mm.

SureFire E2D Defender (LED) lamps
If, in a range that may depend also on the life of them, there are products of the manufacturer SureFire probably no alternative. The highest quality standards and a philosophy, is not considered in how a product is cheaper, but only improved as it will stand behind SureFire. The price spiral starts at 150 € upwards.
