ULTRAFIRE Black Light UV Flashlight, Super Power UV 395-405 nm LED WF-502B Blacklight Flashlights for Leak Detector, Pet Urine Stain, Bed Bug (Not Included Batteries)

An amazing product

Very nice for the price. I've been using a pocket UV flashlight powered by 3xAAA for the longest time for lures and circuit board work. Recently I changed to a different resin and that old flashlight just takes forever and burns through batteries like crazy. (AAA flashlight on left, this ultrafire on the right in photos) Was looking for an 18650 or 21700 powered flashlight since I have such batteries readily available. This thing kicks. Far more powerful and it has a focusable lens which is superb for when I only need to cure in a small area. It has no charging circuit. So you will need a way to charge your 18650 outside the device. Very solid construction. Pleasantly surprised. The clip is secured with screws not a tension ring. Total game changer. Never have to worry the flashlight escaped the clip. Size is nice imo. Good hand fit for holding normally. Little awkward if you want to hold it like a penlight though because it's back heavy. Only con: no lanyard/ring hole I would buy more of these for ice fishing (jigging glow in the dark lures) but without a way to secure it to my person I might have to pass. There are holes in the clip if you wanted to tie on there but then it gets funky not hanging straight.

This is a powerful UV flashlight that really does its job well. Whether you’re checking for pet stains, leaks, or other hidden messes, the beam is strong and clear, and it reveals details even in well-lit areas. The one thing to note: it requires a 18650 rechargeable battery, which isn’t something most people have lying around. You’ll likely need to order it separately, and it’s not included with the flashlight. Still, excellent performance overall—just be sure to have the right power source ready to go.

I wanted a cheap, single led, uv light for disc golf. The multi light affairs seem weak. I have a charger and a bunch of 18650 batts so this was perfect. It will be great for throwing at night or finding discs at night that I lost earlier. It charges my Eclipse discs in a snap. Noticed someone complained about batteries down below. You can get cr123a batteries at almost any grocery store and two should work fine . These are not rechargeable and therefore fairly inexpensive. I think they have less voltage and last a bit, while an 18650 will have higher output for shorter periods....at least I think that's how it works.

Love it

This item needs a special battery that is not included. I returned it.

This is a great UV flashlight. I use it for curing resin and also for charging up glow in the dark 3D printed things. For curing resin it doesn't do it instantly. You do have to hold the light over it for a little bit, but it does cure the resin. For charging up glow in the dark things - it's instant! It's crazy how good it works for that and definitely fun. Also... wow, you'd be surprised how much lint you probably have on your shirt. Haha. UV light picks up a lot of things that you may not noticed until you use one. Don't shine it on cheap hotel sheets. You'll never sleep again.

To start this review I’m using this light along with oil dye to find a slow leak in an engine. I’m using 2 brand new cr123a energizer disposable batteries in the light. Initially I was very happy with the light output. I then used it continually for maybe 15min to look for the leak. The light head did get hot like typical led lights do. The part that disappointed me is when I tried to use it again the next day. I turned it on and it lost 25%-50% of its original light output. I tried putting in 2 new cr123a batteries and I even tried a high drain 18650 and the diminished output still remains. Sadly I’m stuck with this light as I don’t have time to wait for another light. I may have to locally source another light. I guess if you do purchase this light don’t let it get hot use it intermittently and maybe it’ll last for you. I can only assume that the heat caused the lack of output problem as I didn’t drop it and I used brand new of the shelf disposable cr123a batteries.

I got this light to see how much of a crime scene the cats have left around the house. This light shows there’s a lot of crime in this house.

Product does not come with the batteries required to operate it.
