There is a reason why some types of lighting are called emergency lighting. It is because, they are highly reliable and amongst the few sources that can be trusted in an emergency situation. The definition of emergency has changed quite a bit in recent times and lighting for emergency has to stay up to date with it as well. When you are thinking of investing in such lighting there are some things that you need to keep on top of your mind.
The first thing about emergency lighting is the ease of their use. They shouldn't comprises of overly complicated circuits. The lighting equipment should be extremely portable, which will allow you to carry it easily, wherever it is required. Along with portability, the ease with which the lighting can be manipulated or customized is an important usage factor. For example, LED modules are usually seen handled by a control circuit that is simple and quite easy to use. These control boxes allow you to have several flash patterns that can alternately be used. Some LED light bars come with as many as 15 flash patterns with alternating colors that not only enhance the brightness, but also are more attention-grabbing, which is an important quality for lighting to be used in emergencies.
Another important feature of emergency lighting is the power consumption. This is expected to be as low as possible. This is also the reason why light emitting diodes are preferred instead of halogen or xenon lights. LEDs hardly waste any energy in the form of dissipation of heat. Also sufficient brightness is provided by simple 1W LED bulbs which can be used in arrays to provide intense light with low beam temperature. Low power consumption will also allow you to carry less batteries or power sources especially on emergency or camping expeditions when such lighting can be used. This is one reason why LED emergency light bars are used more often these days compared to normal flashlights, in crisis situations like floods or other natural disasters.
Emergency lighting should also be good for use in different weather conditions. It is common to find, LED modules which are epoxy coated to save them from the effects of moisture. Similarly, polycarbonate coating is also used in some cases, to diminish the effects of harsh weather. Lighting used in emergencies has to function in exactly the same way in bad weather conditions as it does normally. Lighting used on ambulances, fire engines, highway patrol cars and cop vans should be luminescent and effective in all situations. Brightness of lighting is also important especially under hazy and foggy conditions, where visibility is of prime importance.
Apart from low power consumption and intense brightness, emergency lighting should also be picked for longevity. This lowers the cost of the lighting which is important. Thermoplastic surfaces of the LED modules allow them to be resilient. Chrome deflectors and lenses are used along with these to enhance the visibility of the lighting anyway. These developments in construction offer good choice for those selecting lighting for emergency situations.
