UV Flashlights Increasing In Popularity

The uv flashlight – also called a black light flashlight – has been increasing in popularity for several reasons.

Those who live in warmer climates like it, because it helps them find scorpions and destroy them before they get stung.

People who use glow-in-the-dark objects like the way it recharges the object, if it lost some of its glow-in-the-dark ability. For example, people who like to play disc golf after sunset.

And someone who likes to ensure the cash they take in isn’t counterfeit likes the uv flashlight because it helps them look for the security strip printed on $5, $10, $20, and $50 bills. If currency being viewed under a uv light doesn’t show a security strip, then it’s counterfeit.

HVAC specialists like the way a uv flashlight can help them find leaks, using special uv dye.

And pet owners like the uv flashlight for the way it helps them find where their pet spit up. For example, John Doe pet owner is on the way out the door, to go to work, when he sees his cat throw up on the carpet floor.  In a hurry, John simply wipes up the throw up, and figures he’ll do a more thorough cleaning when he gets home from work. However, once he returns home, after work, he can’t find the spot where his cat threw up. No problem, all he has to do is wait until it gets dark, and then shine his uv flashlight on the carpet.  It will cause the area where his cat threw up to luminesce or glow slightly.  Then he can see more clearly where to do a more thorough, deep cleaning of the spot.

What’s An LED?

The first example of LED usage one may remember is the alarm clock; LEDs were used for the displays. Other uses people may recall were red and green status lights, like on a pc. They would blink rapidly, to show that your hard drive, or CD-rom, was being accessed.  Some might call these “indicator” lights. By now, any home with a computer that gets on the internet via a router or DSL modem will have a room with numerous blinking and flashing LEDs – some red, some green.

LEDs are now much more common than they used to be. Just some examples are light bulbs, car brake lights, traffic lights at intersections, flash lights, lighted airport taxiways and runway, and freezers at the grocery store (the kind with the large glass doors.)

So why have LEDs become more commonplace? Well, for starters, researchers have proven the incandescent light bulb to be very inefficient. And tests have shown that LED lighting is much more energy efficient. Another reason LED lighting has increased in popularity, is that the cost to manufacture LEDs has steadily  been decreasing. They might be more expensive to purchase than the alternative, but since they last longer, it’s making more and more sense to go with LED lighting.

All this tells us that LEDs will continue to be become more and more common place in our everyday lives, as advancements continue to be made.
