It emits a pure 365nm wavelength, which is ideal for a wide range of applications like forensic work, mineral hunting, leak detection, and pet stain identification. One of its standout features is its long battery life, offering up to 7 hours of continuous UV output on a single charge—more than twice the usual runtime of standard models, thanks to included high-capacity lithium-ion batteries and an intelligent charger.

Built from aircraft-grade anodized aluminum, this flashlight is sturdy and water-resistant (rated IP65), making it durable enough for outdoor or demanding environments. Its size is moderately compact (about 8.6 inches long and 7.2 ounces), balancing portability with a good grip and handling features like a lanyard and holster, which enhance convenience during extended use.

The package also includes helpful accessories such as a carry case, spare filter lens, and charging cables, supporting professional users who need on-the-go solutions. This flashlight is tailored for users needing longer operational times and better accessory support and might be more than what casual users or those with minimal UV needs require. If you need a reliable, high-quality UV flashlight with excellent battery life and durability for professional or serious hobbyist use, the uvBeast V3 365nm PRO is a strong contender; for everyday or simple tasks, its advanced features might be unnecessary, and a lighter or less expensive model could suffice.

The Hoxida UV Blacklight & High Lumens Flashlight combines two useful lights in one: a strong ultraviolet (UV) light and a bright white LED. The UV light shines about 13 meters, which is farther and clearer than many regular blacklights, making it great for spotting pet urine, scorpions, or checking for fluorescent stains. The white LED can reach up to 2000 lumens, bright enough for outdoor activities like camping or walking your dog at night.

It runs on a rechargeable lithium-ion battery that lasts up to 20 hours on low light, and charges quickly through a USB-C port. You can even use it to charge other devices if needed. The flashlight is made from sturdy aluminum, designed to handle rain and drops, so it’s reliable in tough conditions. It’s a bit heavier and bulkier than simple pocket flashlights, but that’s expected given its powerful features.

The controls are straightforward with two separate buttons for UV and white light, plus six lighting modes including strobe and SOS for emergencies. You can adjust the focus to zoom in or out, which helps when you need to see details up close or scan a wider area. This flashlight is a bright and long-lasting choice for detecting stains, pet accidents, or insects, and also doubles as a strong regular flashlight for outdoor and emergency use. While it is not ultra-compact, its price and versatility make it a solid choice for pet owners, outdoor enthusiasts, and anyone needing a dependable UV and LED flashlight combo.

The flashlight's small size (just over 2 inches in length) and lightweight (3.17 ounces) make it highly portable, fitting easily into a pocket or bag.

Additionally, it boasts an upgraded UV power, wider beam, longer working time, and a rechargeable battery, addressing common user frustrations with ease of use and reliability. The convenient double-click switch helps prevent accidental activation, adding to its practical design.
