More Efficient LED Flashlights Are Taking Over
Flashlights, called torches in British English, have been around for a long time. Hand portable illumination is clearly desirable in many situations. LED flashlights use the latest LED lighting technology to produce a better product in almost every way.
The first flashlight was introduced in 1899. It was made possible by the development of portable batteries with paste electrolyte instead of liquid as had been used before. Early flashlights, along with most of them for the next 100 years, used incandescent bulbs.
Incandescent bulbs heat a wire till it glows by sending electricity through it. The wire is inside a glass bulb. This process is very inefficient compared to LEDs. The bulbs have pretty short working lives. Dropping the flashlight tends to make the working life even shorter.
Flashlights can be made with fluorescent bulbs. Their efficiency is between incandescent bulbs and LEDs. Even though they are bulky and easily broken, there used to be a niche for them. Now that LEDs have come down in price, fluorescent flashlights have pretty much disappeared.
The invention of the white light LED (light emitting diode) changed the flashlight game. Colored LEDs have been around for awhile, but are not generally suitable for use in flashlights. White light LEDs are incredibly efficient producers of light. They are shock resistant and have long service lives.
The major restraint on market success of LED flashlights has been their relatively high cost. Until the last couple of years they were so expensive that they were not used except for special applications. Their cost has been going down continuously and has reached the point where they are almost always the flashlight technology of choice, except in cases where extremely low cost is important.
LED flashlights can be much smaller than incandescent flashlights with the same light intensity and battery life. This is partly because a small LED can put out more light than the same size incandescent bulb. An even bigger factor is that the greater energy efficiency of the LED allows it to operate for the same amount of time with a much lower weight of batteries.
If you look around you will see some creative designs for LED flashlights. The old headlamp has been reinvented in a much more compact, comfortable form. There are modular units that can be several flashlights or put together to form a brighter light. Key chain flashlights are now actually usable. There is a model that straps to the arm. Six LEDs spread around the strap illuminate whatever the arm is pointed to.
LED flashlights are taking over the market. They represent a superior technology with a price that is now reasonable. It is hard to think of a reason to use any other kind.
Create A New Photography Style Using Led Flashlights
Flashlight photography is an emerging technique being pursued by photographers. Using a flashlight in photography allows a photographer a new avenue of imagination and creativity for the photographer. When used correctly, LED flashlights can mimic natural lights and create effects not possible in photo imagining and manipulation software. LED lights allow the light source to be directly controlled by the photographer’s vision. The following are some basic equipment tips and techniques.
The Right Camera
The single-lens reflex camera, or SLR, uses a mirror to accurately reflect to the photographer the same scene that the camera does. The digital SLR, or D-SLR, has the same capabilities as the film SLR, but uses a memory card instead of film. Either type of camera is great for flashlight photography because you can adjust the shutter to a long speed, which is perfect for LED light techniques.
LED Light Tips and Techniques
It is helpful to use a lot of LED lights to get a good quality picture. LED lights tend to be on the small side, and don’t give off a whole lot of light. But don’t worry – LED lights are fairly cheap and you can get dozens of them for just a dollar or so.
LED lights are wonderful hard lighting sources, because the light of LED flashlights is extremely focused. A photographer can use the LED flashlights by placing one or more flat on the ground in order to light up the bottom of an object or some other specific focal object. If you need LED lighting going upward, stack LED lights on top of each other in tripod fashion.
Another way to use LED flashlights is to use self-adhesive Velcro to make a hook strap that wraps around the lens of your camera. Allow two extra centimeters slack for attaching some loop Velcro. Connect the loop side to the hook side with the adhesive side facing outwards. Next, attach the LED lights to the adhesive side one at a time until you cover the entire strap, and voila! You now have your very own LED lighting source for pointing LED light directly at objects, and you hardly spent a dime.
Natural Photography and LED Lights
Combining LED lights with other flashlights, natural light or camera lights can achieve interesting experimental effects. Try using a flashlight held in front of your camera flash with no direct sunlight. The combined lights can add a natural warmness to your photo, making your photo interesting and unique. Another experiment is using different white balances through different colored gels or color filters in front of white LED lights. This technique can simulate several white balances of natural light. LED lights can also be used to “paint” light across an image by using a slow shutter speed and sweeping the LED flashlight across the scene.
Using macro techniques, where the lens to subject distance is much closer than usual, LED flashlights allow the photographer to mimic and/or enhance night shots. This method can allow an aesthetic white balance in spot lighting photography sessions.
What you need to know about LED flashlight
It is true that everyone living in this contemporary society benefits from LED flashlight. One can use LED flashlight for camping, hiking and other kinds of outdoor activities. On one hand, a large number of consumers are enjoying the enormous benefits and convenience brought by LED flashlight. On the other hand, even more sellers have already successfully made profits from LED flashlight business and are attempting to earn more money in the next decade. But still there is something you need to know about LED flashlight.
To begin with, you need to pay enough attention to the battery type and battery life of LED flashlight. It is widely accepted that LED flashlight is more efficient than traditional incandescent flashlight. Although LED flashlight is an energy-saving electrical device, it does not mean that LED flashlight has an exceptionally long battery life. As a matter of fact, the battery life of the particular LED flashlight is affected by many factors which include the battery type, the number of LED’s, the amount of light given off, the rated power, etc. Generally speaking, there are two kinds of batteries: alkaline battery and lithium battery. Compared with alkaline battery, lithium battery is more expensive but it lasts longer and performs better in low temperatures. Of course, apart from battery type, other factors also have a big impact on the battery life of LED flashlight.
Secondly, you need to understand lumen and pay much attention to the lumens of LED flashlight. We know that light is usually measured by the special measurement unit of lumen. But lumens only tell a small part of the truth since lumens are measured at the centre of the beam. Thus, it is easy to understand why two different LED flashlights with the same lumen show quite different results. You may find that a keychain flashlight with one LED gives out quite bright light to the centre of the beam but fades quickly at the edge of light while a LED flashlight with several LED’s may give out the same amount of light to the centre of beam but it stills projects quite bright light to the outer circle of light. In other words, these two LED flashlights have the same lumen but one may give out more light than the other. Therefore, you do not need to take lumens of LED flashlight seriously since lumens do not tell you how much light it will give out in total.
Finally, you need to play enough emphasis on the effective projection distance of LED flashlight. Just like a coin has two sides, LED flashlight also has some drawbacks. One of the most drawbacks is that LED flashlight can not throw light as far as one incandescent flashlight. However, most consumers are not annoyed by this factor since most of them use LED flashlights to see things relatively close to them. Of course, if you are especially critical about the effective projection distance, you need to note it whenever you are about to choose one LED flashlight.<
The Truth About UV Animal Urine Detector Flashlights
When trying to find a solution to find pet urine spots in your home, it can be overwhelming. There are A LOT of products and brands to select from. However, sadly not all are made equal.
First of all there are the fluorescent tube lamps, which can provide results, however they usually require you to be so close to the stain in order to see it fluoresce that finding the stain is hard to begin with.
Luckily the new breed of LED UV flashlights makes finding urine stains much easier with a more powerful and more concentrated beam of UV light. However, good LEDs are not cheap to produce especially at the lower wavelengths which are required to make the proteins in urine spots fluoresce efficiently.
You will see that a lot of UV LED Flashlights being offered under the $20 price tag which are marketed as urine detectors, however on closer inspection you’ll often discover that they do not discuss the UV wavelength (a value in nanometers or “nm”) since it’s at the wrong end of the spectrum closer to actual visible light (about 390-400nm). This wavelength range can make some spots fluoresce, however it’s not proficient at it and often overwhelms the already limited stain fluorescence with bright purple visible light. Not useful at all when searching for urine spots around your house – so be sure to watch out for the true wavelength output.
The manufacturers of these UV Flashlights sometimes make use of gimmicks such as a large amount of LEDS (in some cases as much as 51 LEDs!) as marketing techniques to make the flashlight sound powerful and as though it will output a really strong UV beam. Well, with that many LEDs shining away it will definitely be bright, however unfortunately this is not going to help if it is with the cheaper 390-400nm LEDs; the larger quantity simply compounds the difficulty these wavelength LEDs have in the first place because a larger quantity of visible light is output if more LEDs are added.
So exactly what’s the solution?
Utilizing LEDs that output a lower UV wavelength of 365-370nm is the trick. The drawback here is they are FAR more costly to manufacturer and so you will be hard pushed to discover a good UV Flashlight containing these lower wavelength LEDs under $30 not to mention $20!
There are professional level UV flashlights used in forensic science and various other professional areas, however these range in the $200+ price bracket – well above the budget plan for the average animal owner who just wants to find some animal spots in their house.
The best way is to look for a solid UV flashlight with 365-370nm which contains the right amount of LEDs – just enough to do the job well yet not too many that the cost ends up being to expensive. UV flashlights such as this are bizarrely hard to find, and is why the “PeeDar” was made; to fill this gap with a trustworthy well considered solution which doesn’t break the bank.
A flashlight like this will have to be used in the dark – no lights on and after sundown, however it will work really effectively and will rescue you from wasting an awful lot of money and stress from either purchasing a super costly professional UV flashlight or from trying one cheap UV flashlight after another hoping to obtain decent results each time.
We hope this post assists you on your journey to successfully finding and eliminating those pet urine spots in your home!

Finding The Point Of Entry In The Dark Without A Flashlight
Finding The Point Of Entry In The Dark Without A Flashlight
What do these people have in common besides the first letter of their first name?
• John has been a successful salesman in the technology field for longer than he can remember but his company finally gave up the battle with the economy and closed its doors. He hasn’t had to do a resume or apply for a job in more than 20 years.
• Jane was married to her husband for over a century and he suddenly died of cancer. She hasn’t ever managed family finances and has no one to help her.
• James grew up never knowing who his biological parents were. He never really felt loved and couldn’t love somebody else enough to make any relationship work. He is getting divorced for the fourth time.
• Jessica is being bullied at school but everyone thinks she is exaggerating just to get attention. To make matters worse, she has ADHD and her mother is out of work and can’t afford the expensive medication that helps Jessica focus.
• Jackie is really a girl in a boy’s body and really confused as to what to do about it. No one else seems to understand the emotional horrors of this physical dilemma.
• Jacob is a highly educated music director at a large traditional church. People are complaining about the difficulty of following his complicated church music; everyone seems to prefer the more progressive “karaoke” style of singing.
• Jenny is stuck in a creative, helping career with a non-profit organization, being stymied and held back by an overly conservative bureaucracy in the community that won’t recognize the problems she sees and wants to correct.
Today life has grown way past a series of little problems to solve in order to survive. We now all have one thing very much in common: Problems are becoming more complex and complicated and we are all getting overwhelmed in trying to resolve the volume and frequency of the unfamiliar and painful situations that are constantly bombarding us. We are trying to find a point of entry to begin to resolve these problems, but frantically searching in the dark without a flashlight. The bumps, bruises and bleeding are getting worse.
Seeing a problem clearly—especially the complex and complicated ones—is always half the solution. But today, that seems to be much easier said than done. Never-the-less, the intense difficulty of what we are all trying to do here, has to really sink in beyond mental philosophy…because that IS the flashlight that helps us see the point of entry.
When we finally see what is going on—that we are perched on a cliff and are posed to fly or fall—we realize we are being forced to face our most basic insecurities. The flashlight we are looking for is the realization that the awful pain of problem-solving has become worse than it needs to be because we have such a hard time letting go to what we believe will work. Oddly, most of the things we believe to be true are exactly what is holding us back from flying off the cliff, being very stuck in the fear of falling.
Here are our opening characters’ flashlights to show them their points of entry:
• John must open up to the possibility that he has allowed himself to get too comfortable in the wrong job. His unemployment may be an opportunity for him to “grow up” and start doing something that will help him fulfill his real purpose in life, such as helping others find their way out of such a conundrum.
• Jane is being forced to confront a main problem in life she has comfortably avoided—money management. And financial advice today is abundant and much cheaper than it has been, which is probably what got us in the current crisis; so, she can work both ends of the stick together for her solution.
• James has to do the one thing in life that is the hardest to do—to learn to love himself when all his evidence is to the contrary. But, the truth of the matter is, you can’t do the only thing that nurtures and sustains good relationships—unconditional loving—until you see that life is already doing that for you, with all your flashlight battery-zapping shortcomings, flaws and wrong-doings.
• Jessica won’t be the first kid to survive with ADHD without the meds. By simply forcing herself to focus on understanding that bullies bully out of jealousy and frustration with their own mental suffering, the sting of her own suffering goes away. This frees her to succeed in doing what she is in school to do, which is learning how to succeed in her life work after school.
• Jackie has to stop trying to figure out something in his head, about which his heart has the only real clue. But that is usually seen as a cop-out by others. Getting to “So what?” is the flashlight to his difficult point of entry.
• Jacob simply has to let go to his main purpose—to help church members grow their feelings and spirit through music, however that works best and easiest. Listening to what others want and need is hardest to do when we “know better” because of our own knowledge and position. We are usually blind to this flashlight until we stumble upon it already lit in the darkness.
• Jenny is ahead of the curve with the rest of her cast. She already knows she really only has two choices, either of which will work: (a) To take a chance, fly the coupe and reach out to a more accepting audience, or (b) Shorten the distance between her hopes and fears and those so prevalent in her current audience. This is a hard choice because it is protected by the belief that you can’t have your cake and eat it too. “Says who?” is her point of entry flashlight.
John Lennon is still right: “There are no problems, only solutions.” We just need flashlights to find them in the dark.
