The UltraFire UV Flashlight operates in the wavelength range of 395-405 nm, which is effective for detecting pet urine, curing UV glue, and leak detection. Its light output is noted to be 30% brighter than many competing blacklight flashlights, making it useful in various lighting conditions, whether indoor or outdoors. This brightness can be beneficial for tasks such as pet stain detection or spotting leaks that may otherwise be missed. However, it's positioned as a tool for specialized tasks, so its brightness might not suffice for other general UV applications requiring higher intensity.

The flashlight is powered by a single Lithium-Ion battery, which is included. This battery type is known for offering good longevity and consistent power, but users may need to ensure they have a charging solution handy, especially for prolonged usage. Durability is a highlight, with the flashlight's aluminum construction boasting an anti-abrasive surface and IP65 water-resistant and dustproof rating, making it suitable for a variety of environments and ensuring it stands up to regular use. Additionally, the adjustable zoom function allows focusing the light from wide to narrow beams, adding to its versatility.

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.
