Great scuba lights
These are good lights for lighting up coral and fish underwater. They are a fill light with a nice wide beam. I've used them on night dives and again they provide plenty of light across a large area. Battery time is very good and they have lasted through four day dives (on about 50-80 percent of the dive) and a night dive (on for 100 percent of the dive). They are also robust and can take a beating too. The flashing feature is also useful for signaling the dive boat of your location if you come up away from the boat at night. Good value.

Reliable and well put together
I purchased two of the L12s thinking they would last until I was ready to invest in a full set of "higher quality" lights. So, here I am, 2 years later and couldn't be any happier with my lights and cannot justify spending $800 each for a new set of lights. These lights have proven themselves as a contender in the quality and durability of a higher priced light. How much have I used them? Good question!!! I dive on average every 2 - three weeks, I am a wreck diver so the lights are constantly in use. The average depth of my dives are about 75-80' reaching 100-120 on each dive. They have proven themselves!!! The output is amazing and as a designer of underwater lighting, I tested the LEDs and they are on point for output. By the way, I am writing this as I was looking at other lights and I am staying with what I have...don't be afraid of these lights, they are strong and easy to use.

Great Dive Lights for the Price!
My wife and each bought one of the Leton B-15 dive lights for our new underwater camera housings. We are very pleased with the heavy duty, quality build, and ease of operation. Overall, we liked these so much that we both ended up also buying this item's slightly bigger brother the B-24 separately in a different order. Amazon will only allow us to review one of the purchases from this company, apparently, so this review will be for both orders. TL;DNR Version: Highly recommended, More detail: Operation is simple with two buttons, but we really only use the main light mode button, not the colors or flash pattern (so far). The 8,000 lumens these lights provide is much brighter than our old lights were. Battery life is very good and both typically last us two or three dives if we use mostly the medium setting. The B-24 does eat up more of the available charge percentage on medium, but that hasn't been an issue for us so far. We recharge them at night on shore. The batteries are included, but we did need to buy a rapid charger that has both 110 - 240 volt adapter for travel. That was about $45, but charges eight batteries at a time. We usually can charge both sets of eight batteries overnight. Overall, we liked these so much that as I said, we both ended up also buying this item's slightly bigger brother the B-24, too, and carry one of each on each side of our dive camera setup. There is not much difference, frankly, in output. They are identical in terms of operation and controls. Good product at a reasonable price!

Comes with no way to charge the 4 specialized batteries
I’ve had these lights for a couple of months now, and only took them under water once. The good news there is they didn’t flood. My initial impression was “oh boy, these things are BRIGHT. The mounting hardware assembled easily, and I was able to get them mounted on my Gopro tray with no issues. My happiness with what was looking like a heckuva deal was diminished when I went to charge them. There is no charger. There is no charging cable. To be fair to Leton, it does say, way down in the page, on a single line mixed in with other text, no charger buy your own. But the video on the page shows a guy unscrewing the bottom cap, removing tray with the batteries in it, and there is a USB-C port on the tray. So, being fair to me, that’s a hoodwink. Unlike the guy in the video on the product page, my lights have no cap, no tray . . . just four 18655s that need to be charged SEPARATELY…in chargers YOU provide. Fortunately, I have some dive lights that use the same batteries, so I have a couple of chargers. But there are four batteries…in each light. 8 batteries total that I have to charge with 2 chargers that I just happen to have. Charging is going to take a five paragraph OPORD (for those who know what that is) and a month’s worth of planning. I don’t know what you would do if you missed the fine print and didn’t have a charger. Requiring each battery to be charged separately and not including a charger costs these lights 2 stars. I get that we’ve reached the age where hardly anyone is including chargers with electronics, but most dive light companies are at least building it in to the batteries (e.g., Orcatorch) or the case itself. There is no reason for Leton to cheap out like this. $99 should get you a charger or a built in charger. I’ll update this review when I get a chance to dive with them…probably next month…after I charge 8 batteries two at a time… UPDATE 9/9/25: Leton reached out to me regarding this review. We had a good back and forth discussion about how Amazon listing pages worked. A long story somewhat shorter, I learned that some of it, like the Product Showcase section where the video is, cannot be controlled by a vendor. They accepted that customers could be confused despite the underlying reference to a different light because there is no indication on the video itself which light is its subject. They have agreed to have an internal discussion about it to consider my recommendations. They also offered to send me a charger even though I told them that was not the goal of my post. Giving back one star because of the open-minded responsiveness of Leton. But do remember, the B24 light — as it comes from Leton — has absolutely nothing in the box that will allow you to charge its batteries and that even after you get a charger, each of the four batteries must be charged one at a time.

充電式なのに充電器が別売りなのが、不便だと思います。あと付属のヒモは長すぎて使いづらいので、別のものを買う必要が有ります。 ライトの性能は満足です。
