I bought this to look for golf balls that get launched into the woods. Extremely bright and effective! Definitely worth the price. Charger works and charges to full decently fast.

Is really nice and strong light

Works well as far as I can tell very bright

This is a small, high quality black light flashlight. It is heavy and very well made. It produces a strong 16 watt beam of intense UV light. The unit is waterproof and is rechargeable. The flashlight comes with a USB cable for recharging. It is made of high quality aluminum and is very durable. I use it for detecting traces of urine left behind by my old incontinent cat. Works just great.Damon M Tatem

This is a super bright light. No doubt there. It is rechargeable and the battery is an 18650 which are fairly common these days. I keep extras on hand and charge them in an external charger so there's no down time for the light. If you wanted to charge the light with the plug in USB cable, you simply unscrew the head and it reveals the plug in.The size is good for my hands, and I love the tail end switch. But... what I don't like is the click combination to turn the light off, to find another brightness setting, and to activate the strobe. None of which is complicated but I really prefer a one click on, and a on click off.This comes with a case but it's a hard case. I like that it has a molle type strap on back but the "lid" of the case is hard and is awkwardly bulge-y on your side.One final note, this is not the first Ultrafire light I've owned. I had another brand new one that fell as I pulled it out of its holster, hit the ground, and never worked again. However, Ultrafire customer service was awesome to deal with and I had a new light within about a week. You can be confident that their customer service has your back.

Good versatile flashlight

Solid build, easy to use, and works exactly as expected. Definitely recommended.

There's always something wandering around our ranch after dark, and I wanted a light that could really reach out and illuminate those unwanted visitors. Well, this little monster certainly delivers!This ULTRAFIRE 501GX puts out a claimed 600 lumens of green LED light, with a 520–530nm wavelength. I was honestly surprised by how much light comes out of something this compact. The beam is strong, bright, and has some impressive reach. It's exactly the kind of visibility I wanted for checking out those darker areas around the property.I also really like the included accessories. The Picatinny rail mount, pressure switch, and adjustable mounting options make it much easier to get the light positioned where I want it. The hidden USB-C charging port is another nice feature, especially since I prefer rechargeable gear.Where It Lands: Small package, impressive brightness, and plenty of useful mounting accessories. I'm really happy with the beam strength and overall versatility. Those four-legged troublemakers around the ranch won't be quite so hard to spot after dark!

What initially drew me in was this light hit all the big boxs, I wanted a slim design, green laser, double sided clip and I loved the battery indicator and orange color. One big thing that wasn’t listed anywhere was a base magnetic. This was critical for me but given this light hit all box’s I was willing to gamble see if it had one and if not I was willing to put one on myself. Lo and behold when I received it I found it does in fact have a base magnetic making this light absolutely perfect! Unfortunately this light at this time doesn’t advertise this feature and I couldn’t find a single review video of this light. This light is also a fraction of the price compared to similar flashlight available, time will tell how well it holds up.

This is my second Ultrafire flashlight and it's excellent like the first one. Only this one is single function. No bells and whistles, no multi-light settings. Just on and off. At the tail of the light. There's also no focal adjustments. It's just a practical, bright light. That shines a long way and keeps excellent beam integrity while doing it. And it comes with a lanyard you can attach if you want. As far as how much charge it has left, a small LED light above the charging port comes on briefly when you turn the light on. Green, yellow or red. Flashing red when critical. When charging, it goes from red to green. It also comes with a real marvel and surprise. Another light in true EDC fashion. A keychain light with three modes and a tiny little digital percentage LED readout of how much energy it has left. Two brightness levels and on the third click, a strobe. It's so small, but so darned powerful and capable! Very much like the other EDC light I got from them. So anyway, what a treat to get that light with the bigger power-beam flashlight. Which is bigger than the small ones I have several of, but smaller than the normal large flashlights, if that makes sense. The case is aircraft aluminum and has some nice machining on it to allow you to get a good grip on it. The charging ports of both lights are waterproofed with a silicone cover and take the usual USB-C plug. And they included one for each light. The main light is waterproof to two meters and impact resistant at one meter. Considering the two light combo and the performance of each, I think this set is an excellent value.

I have a bit of a love/hate relationship with flashlights that have a dozen different modes. Sometimes I just want to turn on a flashlight without clicking through low, medium, high, strobe, SOS, disco party, and whatever else someone decided it needed. This Ultrafire gets major points from me for keeping things simple: on and off. That's it. More importantly, it's extremely bright. This is definitely designed as a long-throw flashlight, with a concentrated beam that reaches an impressive distance rather than flooding a huge area immediately around you. I can see this being particularly useful for camping, checking a large yard or property at night, walking outdoors, or anytime you need to see what's happening farther away. That's also consistent with other users' experiences with the unusually long, concentrated beam. The flashlight itself feels substantial and well made without being ridiculously oversized. There's also a simple color-coded battery indicator, so it's easy to get an idea of how much charge remains. USB-C charging is another big plus. But the unexpected bonus is the little rechargeable EDC keychain flashlight that comes with it. I initially considered that an extra, but it's surprisingly useful in its own right. It's tiny, very bright for its size, has multiple light settings, and even has a digital battery percentage display. The flashlights were both almost fully charged on arrival and I stuck the tiny one into my purse immediately. This feels like two genuinely useful flashlights rather than one flashlight with a throwaway bonus accessory. The main light is powerful, straightforward and built for distance, while the little EDC light handles the everyday stuff.

This was a much nicer flashlight than I was expecting. With that being said, it would not be a good "around the house" flashlight. This light produces a very thin and concentrated beam. It is perfect for long distance use. The thin beam and full-brightness on/off output is perfect for that use. The good news is the keychain light it comes with is also a fantastic bit of kit for up close. The option to choose a bright-white light or a soft-white light is perfect. The soft white option is great for inside The build quality of the main light is what surprised me. The light has a spring for each side of the battery so it stays lit if you drop it. The electronic in the head appear to be potted to help against water intrusion and impacts. The tail click button is recessed below a metal rim on the back of the light so you can stand the light up vertically on a table. This light works great for ceiling bouncing because the reflector lens is very deep. It's hard to accidently blind yourself by looking at the light when it's on. This is a good light for the specific use of seeing things far away.

I got this flashlight for my husband, and he really likes it. 🔦 It is a nice flashlight and has a good, solid feel to it. He likes having a bright flashlight like this around for when he needs one. It is rechargeable with USB C, which is really convenient, and I like that it has a tail switch that makes it easy to turn on and off. The design is also nice and compact enough that it doesn't feel like you're carrying around something huge. One funny thing is that he actually really liked the little keychain light that came with it. 😂 I wasn't expecting that to be his favorite part, but he thought it was really handy and has been enjoying having it. I'm really happy I picked this up for him. The flashlight itself is nice, and the little keychain light was a fun bonus that he ended up really liking. 🔦😊✨

Very impressed with this green LED flashlight. The beam is bright, focused, and provides excellent visibility at night without the harsh appearance of a traditional white flashlight. The 520–530nm green light is easy to see and works especially well when you need to illuminate an area at a distance. The flashlight itself feels solid and well constructed. It’s comfortable to hold, easy to operate, and the 600-lumen output provides plenty of usable light for outdoor nighttime activities. The beam has good reach while still providing enough illumination to clearly see the surrounding area. I also appreciate that this comes as a kit rather than just the flashlight by itself. Everything works together well, making it convenient to keep ready with the rest of my outdoor gear. Overall, this is a powerful, practical green flashlight with good build quality and impressive nighttime performance. It does exactly what I wanted it to do and has been reliable so far. Excellent value and an easy five stars.

While this flashlight is marketed mainly for hunting, I got it so my son and I can watch for animals at night. We like to sit on our deck when it's dark and watch for deer, foxes, raccoons, and bears. Using a regular flashlight scares the animals off, but they barely notice the green light. The light is far reaching so we get a good view into the woods behind our house at night with this flashlight. It's small and fits easily into a pocket, making it easy to take on nighttime walks as well. I accidentally found out how well it enhances your vision when I tested it inside. I washed my floor that morning, but by evening the flashlight picked up every tiny crumb and cat hair from the day. The light uses a rechargeable 18650 battery, which are pretty easy to find if the included one eventually needs to be replaced. I've used it maybe 5 times for about a half an hour to an hour each time and still had almost half a charge on the battery. It's got a solid build without being heavy. This has been fun to use for critter spotting, so I imagine it would be great for hunting.
