10 Best Black Light Flashlights 2025 in the United States

The ESCO LITE Escolite UV Flashlight is a solid choice if you need a black light primarily for detecting pet stains, bed bugs, and other household uses. It features a 395nm UV wavelength, which is effective for showing pet urine and certain stains, although it only works well on dry urine, so you might miss fresh spots. With 51 UV LEDs delivering up to 600 lumens, it covers a wide area, making it easier to spot stains or fluorescent materials quickly. This brightness level is quite good for a handheld black light.

Powered by three AA batteries (not included), it offers about 5 hours of runtime. Rechargeable batteries are not recommended, which may be inconvenient if you prefer rechargeable options. The flashlight’s body is made from aerospace-grade aluminum, providing durability and heat dissipation, plus it has an IP44 rating for water and dust resistance—good for occasional outdoor use.

Its compact size (around 6 inches long and weighing under 6 ounces) and included wrist strap make it easy to carry and use with one hand, fitting nicely in a pocket or bag. This portability adds to its convenience, especially for tasks like camping or inspecting hotel rooms. While it excels at common tasks like pet stain detection, scorpion hunting, or checking fluorescent items, it is not suited for wet stains or rechargeable battery users. Although well-built, it lacks advanced features some high-end black lights offer, such as adjustable wavelengths or built-in recharging. For everyday household and outdoor UV needs, the ESCO LITE Escolite offers strong light output, good durability, and ease of use at a reasonable price.

The light output comes from 51 UV LEDs, ensuring a bright and comprehensive coverage, which is particularly useful for inspecting wider areas or finding scorpions and minerals outdoors. However, it's important to note that it's powered by 3 AA batteries, which are not included in the package. This could be seen as a minor inconvenience since you will need to purchase the batteries separately.

The flashlight is made of durable aluminum, giving it a robust build quality that can withstand regular use. Despite its sturdy construction, it remains lightweight and portable, weighing only 1.76 ounces and featuring a compact design that fits easily in your pocket. This makes it convenient for carrying around for tasks like hotel cleanliness inspections or detecting pet urine in your car.

With a lifespan of 15 years for the LEDs, this flashlight is built to last. It also offers a range of versatile uses beyond pet urine detection, such as authenticating currency, curing UV resin, and even identifying unwanted substances in cosmetics. However, its reliance on batteries could mean frequent replacements if used extensively. The product also comes with a 1-year manufacturer's warranty, adding an extra layer of assurance.
