4 Ways Flashlights Help Modern Industries

Flashlights are an important survival tool and are useful in many outdoors practices. However, many people do not realize the vital role flashlights play in today’s technology-related fields. Flashlights have become indispensable in many industries and are helpful in the medical field as well. The inventors of LED lights in the 1990s were crucial to electrical, mining and medical practices. Included here are a few of the ways flashlights help different industries.

Medical

In the medical field, flashlights have proved indispensable. Previous incandescent bulbs were not as useful due to their propensity to raise temperature and only operate for a few hours before the bulb burned out. With the manifestation of LEDs (light emitting diodes) in the 1990s, our practice of illumination changed forever. Penlights are frequently used in the optometric practice as a means of checking pupillary response to light. Indications of pupillary distress can reveal proof of neurological problems or even tumors. Many lights are used when doing surgical procedures requiring the use of a scope.

Electrical and Plumbing

Use of flashlights for electrical or plumbing work has been vital for years. Due to the tight working conditions of many electricians or plumbers, having versatile lighting has been indispensable. With the birth of LEDs, electricians were able to have brighter light for work, while avoiding raising the temperature of their work area. Many lights are now able to be placed on flashlights that have bendable heads, making sight in compact areas easier.

Hazardous Areas

In many hazardous areas it can be dangerous to carry any kind of light. The danger of the slightest spark from your light causing a flame was too great. In recent days, the manifestation of non-incendive flashlights has made light in many situations safer. Non-incendive lights, also known as explosion proof or intrinsically safe lights, are designed in a manner so that any possible spark from the light is highly unlikely to set off any explosion outside of the light. These lights greatly increased the safety of working conditions within mines, chemical plants, grain elevators or the engine rooms of ships.

Diving

When diving, it is possible to reach depths where the sun literally “doesn’t shine.” Due to this complication, viewing deep in the ocean was very difficult for many years. With the birth of LEDs, lights were able to be manufactured to allow better viewing under pressure while deep in the ocean. Diving lamps must be watertight under pressure and can be used for night dives or supplemental light under extreme depths. Battery compartments of dive lamps must have a catalyst to recombine any hydrogen gas that is emitted from use, as it is impossible to have any kind of vent when underwater.
