Lighting

Halogen lights are similar to an incandescent bulb, except the tungsten filament is sealed

into a small envelope filled with a halogen gas such as iodine or bromine. The problem with

ordinary incandescent filaments was its relatively short life. This early failure was due to

the tungsten filament burning hotter and thus decaying faster at the thinnest areas. In

Halogen bulbs, the lamp creates a recycling action in which the decaying and evaporating

tungsten redeposits back onto these hotter and thinner spots. Halogen lights can therefore

last up to two to three times longer than ordinary incandescent bulbs and they can also run

at much higher temperatures. Halogen worklights and torches give off a brilliant white light

and are often waterproof and dustproof. A halogen bulb is often 10 to 20 percent more

efficient than an ordinary incandescent bulb of similar voltage, wattage, and life

expectancy. This will allow a 60 watt bulb to provide nearly as much light as a non-halogen

100 watt bulb.

Good quality, high intensity spotlights typically use halogen globes and are ideal for

wildlife spotting. Halogen spotlights have very long, bright beams due to the light being

backed up by large silver mirrored reflectors.
