![]() There are also florescent and LED options, with LED bulbs tending to be more efficient and long-lasting. The major differences between one black light flashlight and another is mostly in the strength of the UV (ultraviolet) light the flashlight emits. And many people also use a black light flashlight in hotel rooms, to look for signs of bed bugs and to make sure the room is as clean as the front desk claims. Professional cleaners and home inspectors use black light flashlights to look for leaks and cracks in the wall that may be undetectable to the naked eye. The latest black light flashlights are useful for identifying counterfeit money, turning up pests, rodents or mites, and also detecting soiled bedding, furniture or rugs. If you have a pet who has occasional accidents, for example, a black light helps identify stains that have faded into the carpet that you don’t even know is there. ![]() The best black light flashlights are useful for identifying a wide variety of things and are a good addition to your basic household toolkit. They may have been a fun accessory for an after-school show, but these days, the best black light flashlights are a useful tool to have on-hand to keep your house clean and germ-free.

Fluorescent paint, by its nature, cannot contain the UV hinhibotors that many paints ahve, that prevent fading in the sun. seems to be a good source as well, and I am sure there are more. If the vendor does a good job of explaining the various frequencies of UV light, that is a good sign that they know their stuff, and are more likely to be a good vendor. You only need to take care with the LED based ones. All UV tube type are great sources of UV lights, as are all the vapor-type bulbs. And keep in mind, that the seller is almost certainly unaware of the technology, so may be a legitimate looser in this process.įor paints, the big names, such as Wildfire, and Roscoe, certainly are reliable sources for both fixtures and paints. But, I emphasize that you really need to know your tech, and read all the seller's description. Amazon, provide that you only purchase "shipped by Amazon" has good return policies, and it is not unusual for them to just say keep it.

But, this page below is a very good resource to compare luminous paints. A picture is quite variable, depending on its exposure, as well as the intensity of the UV Light source, and the quality of the fluorescent paint.
