The first 2D halogen flashlights were made in 1984, and since then several manufacturers have created halogen models. Halogen bulbs create large concentrated pools of light, and the light can be very bright and have a crisp white result. The make up of a halogen bulb includes a mixture of inert and active gases. Halogen light bulbs can create a brighter and more concentrated light because of the fact that the active gases recycle the tungsten (metal the filaments are made of) back onto the filament. This makes the filament hotter and ultimately brighter.

Halogen flashlights have thicker glass, which is hardened to produce a much stronger bulb. The light projected from halogen bulbs is truer to natural color characteristics than some of the fluorescent lights which produce yellow, rose or orange toned light casts. Halogen bulbs also tend to be smaller, which make them ideal for some of the small pocket sized flashlights, but they can also work well in large spot industrial sized flashlights.

Halogen flashlights can be considered more durable because of the make up requirement they have to function properly. Halogen bulbs are not encased in glass, but inside of a quartz envelope. The quartz envelope is very small, and quite close to the tungsten filament which produces the heat. If the encasing was made of glass, the heat would cause it to break. The quartz encasing makes for a stronger and more durable flashlight, and it also protects the bulb and filaments from breakage.

Long Life of Halogen flashlights
Many standard flashlight bulbs burn out over a reasonable period of time. The reason a light bulb burns out is because the heat energy stressed on the filament eventually causes a spot to develop and this stress causes the filament to break. The halogen bulbs recycle the tungsten atoms and replace them back onto the filament over and over again, which helps the filament to last longer. The end result is a brighter, more energy efficient and longer lasting light bulb.
