When looking for a solution to locate pet urine
First of all there are the fluorescent tube lamps, which can provide results, but they usually need you to be so near to the spot to be able to see it fluoresce that locating the stain is challenging to begin with.
The good news is the new breed of LED UV torches makes locating stains much easier with a more powerful and more concentrated beam of ultra violet light. Nonetheless, good LEDs are not cheap to produce particularly at the lower wavelengths which are required to make the proteins in urine stains fluoresce successfully.
You'll find a great deal of UV LED Flashlights being offered under the $20 mark which are marketed as pet urine detectors, but upon closer examination you'll typically discover that they do not discuss the UV wavelength (a number in nanometers or 'nm') due to the fact that it's at the incorrect 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 typically overwhelms the already minimal stain fluorescence with bright purple visible light. Not useful at all when looking for urine stains around your home - so always keep an eye out for the real wavelength output.
The producers of these UV Flashlights occasionally use tricks such as a big amount of LEDS (occasionally as much as 51 LEDs!) as marketing techniques to make the flashlight sound impressive and as though it will have a very strong UV beam. Well, with that quantity of LEDs present it will definitely be bright, but sadly this isn't going to help if it is with the cheaper 390-400nm LEDs; the larger number merely compounds the difficulty these wavelength LEDs have in the first place because an increasing amount of visible light is output if more LEDs are added.
So exactly what's the solution?
Utilizing LEDs that output a lower ultra violet wavelength of 365-370nm is the trick. The drawback here is they are A LOT more pricey to produce and so you will be hard pushed to discover a decent UV Flashlight including these lower wavelength LEDs under $30 not to mention $20!
There are expert level UV flashlights made use of in forensic science and other expert areas, but these range in the $200+ price bracket - well above the spending plan for the average pet owner who simply wants to find some pet stains in their home.
The trick is to get a decent UV flashlight with 365-370nm which contains the correct amount of LEDs - just enough to give good results but not so many that the cost comes to be to high. UV flashlights such as this are surprisingly rare, and is why the 'PeeDar' was created; to fill this gap with a quality well thought out solution which we can all afford.
A flashlight of this design will have to be used in the dark - no lights on and after sunset, but it will function very effectively and will save you wasting an awful great deal of money and irritation from either purchasing an extremely pricey expert UV flashlight or from trying one cheap UV flashlight after another expecting to obtain decent results each time.
We hope this post helps you on your path to successfully locating and removing those pet pee stains in your home!
