>>Short Wave Black Light
There are more than 1 type of UV (black light) lights. Generally, there are short wave lights and long waves lights. The long waves lights are from 315 to 400 nm - often called UVA. They are used for a variety of things, such as pet stains, scorpions, drivers licenses, carpet inspections and a lot of other uses. Both short-wave and long-wave tubes require filters to block the small amount of visible light the tubes would otherwise produce. Short-wave tubes use a separate filter, which must be made of a specialized kind of glass (one of the factors that makes short-wave lamps more expensive than long-wave ones). Some long-wave tubes incorporate the filter as part of the glass like us, while others use a separate, inexpensive filter
Short wave UV light is used most often for mineral observation and detection (sometimes short wave light is called UVC). We have here a small, portable, 4 watt, hand held short wave light. The wavelength is 254 nm. We have had these made especially for Black Lights USA. Let us explain a little more. Short wave lights are available, but they are expensive, often ranging in many hundreds of dollars per light. In the past we have not carried them because we do not feel that casual Mom, Dad or collector wants to spend hundreds of dollars to show their kids fluorescent minerals. It is one thing to spend $25 or so and another to spend $300. As far as that goes, the average person might not want to spend hundreds for themselves either! Now we offer an inexpensive short wave light that can be used for a variety of jobs, without breaking the bank.
Collecting fluorescent minerals is a popular hobby and experienced collectors can use fluorescence for identification purposes. At night or in dark mines or caves, fluorescence can be used to find certain mineral deposits and is a viable prospecting technique. fluorescence is not a common phenomenon being found in only certain minerals. If two minerals are similar and yet one is listed as a possible fluorescent mineral, a fluorescence test could prove important. However if an unknown mineral does not fluoresce, it should not so quickly be dismissed as not being the suspected fluorescing mineral, unless that mineral is reported to always fluoresce. Fluorescence is not usually an absolute property found in all specimens of even a named fluorescent mineral, but there do exist some minerals that are so reliably fluorescent that fluorescence is the best test to use.
This light even has a white flashlight at one end. That way you can see the mineral in UV and then see what is looks light in white light. This is an exceptional advantage.
Short wave lamps which are available to collectors can be very entertaining and useful to identify minerals, however it is dangerous to look at the short wave light source (it can cause blindness) and they should not be used without adult supervision.
This 6 inch short wave light takes 4 AA batteries - we do not supply batteries. Please understand that this UV light is not bright like a $250 UV light - so it will not cause the fluorescence like the expensive ones do.
We are excited to offer you, an affordable short wave light at the low price of:
