turn for focusing that’s really smooth, and like the option to have different beam programmes to suit preference. This makes it possible to use black lights to find antifreeze splashes to help investigators reconstruct automobile accident scenes. Notice the Red/Yellow '20' and the little multiple fibres that are now revealed under a high quality UV light source. The powerful 18 watt Kobra LED black light flashlight emits 385-395nm UV light to will make it easy to unveil anything hidden from the naked eye.

It is a safe form of invisible UV light and is used to energise and activate the STARGLOW range of products. i can see where the house builders repaired holes in the drywall, specs of lint on my black sweater, teeth that have been capped and remaining original teeth show up bright white.Fluorescent tube based black lights generally produce the best results when compare with LED based alternatives. However, they only offer a short effective working range (illumination distance) and require mains-powered operation to deliver their best results, both of which limits their use and practicality. The bitter flavoring of tonic water is due to the presence of quinine, which glows blue-white when placed under a black light.

But aside from the novelty aspect they also have a variety of practical uses inside the house and out that you never thought of! Minerals and gemstones are most commonly made fluorescent or phosphorescent due to the presence of impurities. This means you will see far more detail and in a greater range of colours than any other wavelength.

The emperor scorpion normally is dark brown or black, but it glows a bright blue-green when exposed to black light. Unlike more powerful ones, if accidentally turned on, there is no risk of the LED generating too much heat in your pocket. The frequency of UV light emitted by Black light units should ideally be 365-370nm; exactly the right frequency to make UV Revealing products such as STARGLOW UV Paints fluoresce brightly and energise Glow-in-the-Dark products, so they perform at their very best.

With the Integrated floodlight that shines effectively up to 135 feet, you can inspect entire rooms for pet urine stains quickly. Torches operating in the wider 390nm – 405nm range generally use poor quality ‘cheap’ UV LEDs which produce too much unwanted visible ‘purple glare’ (spill) and too little in the way of a useful UV light.

Long wave UV lights have filters which screen out a lot of the visible light they produce, but not all. Because of that, the black lights we use as hobbyists are a great way to produce long wave UV light. Notice that with this 'pure' UV frequency the '20' and fibres are much brighter than with any other frequency. Some flowers are "ultraviolet" colored, which you cannot ordinarily see, but may observe when you shine a black light on them. Far too much visible violet light (interference) produced due poor quality UV LEDs thus producing a poor quality result, with much of any fluorescence generated masked by the visible purple glare.

Torches outputting UV in the 380nm range perform much better and produce superior results, with a much reduced ‘visible’ (spill) output. This is not the best UV lamp if you simply want to walk around shining your UV light on the ground to find minerals that glow. This is the second E12 V2 that I have purchased from Torch Direct (first one for my wife, this one for me).In case of theft your valuables can easily be traced to you if you’ve marked them with a special UV marker. We just got a puppy and I pulled mine out to check for any spots I may have missed while were potty training him.
