The Correct Kind Of UV Flashlight for Finding Pet Urine Stains

February 26, 2016  

When searching for a solution to discover pet urine spots in your home, it can be overwhelming. There are LOADS of options and brand names to select from. Nevertheless, sadly not all are made equal.

First of all there are the fluorescent tube lights, which can work, but they typically need you to be so close to the spot in order to see it fluoresce that finding the stain is challenging to begin with.

The good news is the new type of LED UV flashlights makes finding stains a lot easier with a stronger and more focused beam of UV light. Nevertheless, good LEDs are not inexpensive to manufacture particularly at the lower wavelengths which are needed to make the proteins in urine spots glow successfully.

You’ll find a great deal of UV LED Flashlights being offered under the $20 price tag which are positioned as pet urine detectors, but upon closer inspection you’ll often find that they do not point out the UV wavelength (a number in nanometers or “nm” for short) since it’s at the wrong end of the spectrum nearer to actual visible light (around 390-400nm). This wavelength range can make some stains fluoresce, but it’s not very good at it and often overwhelms the already minimal stain fluorescence with bright purple visible light. Not practical at all when looking for urine spots around your home – so always keep an eye out for the real wavelength output.

The manufacturers of these UV Flashlights often make use of gimmicks such as a large quantity of LEDS (sometimes as much as 51 LEDs!) as marketing tactics to make the flashlight look powerful and as though it will give out a really strong UV beam. Well, with that quantity of LEDs shining away it will definitely be bright, but unfortunately this isn’t going to help if it is with the inexpensive 390-400nm LEDs; the bigger number just compounds the problem these wavelength LEDs have in the first place because a larger amount of visible light is output when more LEDs are introduced.

So what’s the solution?

Making use of LEDs that output a lower UV wavelength of 365-370nm is the trick. The downside here is they are FAR more pricey to make and so you will be hard pushed to find a suitable UV Flashlight containing these lower wavelength LEDs under $30 let alone $20!

There are expert level UV flashlights utilized in forensic science and other expert areas, but these range in the $200+ price bracket – well above the budget plan for the average animal owner who just wants to find some animal stains in their home.

The best way is to get a solid UV flashlight with 365-370nm that contains the optimum amount of LEDs – just enough to give good results yet not so many that the price becomes too expensive. UV flashlights designed this way are remarkably rare and hard to find, especially ones with a quality construction.

A flashlight of this design will need to be used in the dark – no lights on and after sunset, but it definitely works really effectively and will rescue you from wasting an awful lot of cash and aggravation from either buying an incredibly pricey expert UV flashlight or from chasing one inexpensive UV flashlight after another hoping to obtain effective results each time.

We hope this post assists you on your journey to successfully finding and eradicating those pet urine spots at home!
