With multiple lighting modes including SOS and signal flashing, it offers flexibility for different situations. Its UV wavelength is well-suited for detecting fluorescent traces like pet urine, making it a practical choice for pet owners.

The flashlight is powered by a rechargeable 5000mAh lithium polymer battery, providing up to 20 hours of continuous use, and charges quickly via USB Type-C, so you won’t be left in the dark during extended use. Built from durable aviation aluminum alloy, this flashlight is water-resistant and drop-resistant, capable of handling rough outdoor conditions or accidental falls. Its compact size and anti-slip handle make it easy to hold and operate, even with gloves on.

This sturdy and multifunctional flashlight may be a bit heavier than simpler models at over 13 ounces, which might be noticeable during long use. It suits pet owners who need a reliable, long-lasting tool not only for urine detection but also for outdoor activities and emergencies, offering good value with its dual light modes and solid build.

The ULTRAFIRE UV Flashlight offers a UV Light Wavelength of 395-405 nm, which is effective for detecting pet urine stains even under indoor or street lighting.

The flashlight is constructed from premium aluminum, making it sturdy and durable. Its anti-abrasive surface treatment and non-slip textured grip enhance its build quality, while the IP65 rating ensures it is water-resistant and dustproof, suitable for various environments. The zoomable function allows users to adjust the focus, making it easier to inspect larger areas or specific spots, which is particularly useful for pet owners.

The flashlight is powered by a lithium-ion battery, included in the package, ensuring convenience and long running time.

Powered by two rechargeable lithium-ion batteries, it delivers around 2 hours of continuous use per charge, which is sufficient for typical home cleaning sessions. Its aluminum body enhances durability and provides a sturdy feel while being waterproof, allowing for indoor and outdoor use without worry. The included USB charger and batteries make it ready to use right out of the box, simplifying setup.

Weighing 1.48 pounds, it might feel somewhat heavy for prolonged handheld use. Additionally, the 2-hour battery life could require recharging during extended tasks. While it excels in brightness and range, the weight and battery runtime may be less comfortable for quick spot checks or frequent carrying.

Beyond pet urine detection, this flashlight is versatile and useful for curing UV resin, rock hunting, and even scorpion detection, demonstrating its broad utility. It is a bright, reliable UV light well-suited for finding pet stains, particularly if you value a durable build and rechargeable batteries.
