WINDFIRE Dive Light Scuba Diving Flashlight, Super Bright Rechargeable Waterproof Torch with Power Indicator, 3 Modes Underwater Lights, Scuba & Snorkeling Safety Dive Lights for Night Diving

Got this to increase the visibility when diving underwater in the Harbor. My friend lost his phone the other day, and we were sure it was within 20 feet of the dock. I used this and it held up pretty well at under 10 ft. I was able to see the floor of the harbor, and I ended up locating the iPhone within 30 minutes. The battery life, build quality, and illuminance make this well worth considering for any type of diver.

Needed two lights for night dive certification made 5 dives 3 to 100+ feet it never leaked only actually used it the first dive because I had left my primary light locked out and needed this one to see while I fixed it. I do seal the o rings and threads with silicone grease every time I open it.

Amazingly bright light, better than more expensive rentals at the dive shop, helps with visibility into coral during the day and spectacular nighttime performance. Unfortunately it seems flaky; the on/off button started working only intermittently after 3 uses and one full recharge following a night dive to only about 45 ft. We are outside the return window and if I could have exhanged it for a “not flaky” one it would have been a 5-star review. I dive warm water (no gloves) but imagine this would be a real hassle in colder water with gloves.UPDATE: the seller contacted me after reading my initial review and offered to refund the purchase price even though the flashlight is outside Amazon’s 30-day return window (I bought it for a 2-week dive trip). I am very impressed by the seller, SENDAI, and have asked instead that they replace the flashlight as I really like it and hope it was just a one-off. Boosted my review to 4-stars for the stellar customer support. I will update this review again after I receive it and have the opportunity to use it underwater again.

I have two of the lights and have had them since early 2024 and love them. We live in the Caribbean seven months a year so I use them five or six days a week. In the last two or three weeks I’ve struggled charging them. Until yesterday I could move them around in the charger until the red light came on signifying it’s charging. As of yesterday, I can get neither of the batteries to charge? Has anyone else had this problem and does anyone know who I should contact?

This light is AWESOME and I highly recommend it! First, it's a great value for the price I paid ( about $39 USD ). I bought this light for a trip to Bonaire ( Feb 2025 ) for use during the daytime to see inside and underneath the corals and to see the reds, oranges and yellows that you can't see down around 70 to 80 feet. Several people noticed how bright it was and commented when we got back to the boat. And while I don't recommend you do this, I used it to clank my tank a bunch of times to call other divers over to come see stuff and it held up just fine for some 15 dives (some as deep as 80 feet). The battery lasted fine for two full dives using it intermittently but it started to run down on the 3rd dives. It uses an 18650 battery (which is easy to find on Amazon) so just buy more (with same or higher mAh rating) and swap the batteries if you want light for more than two dives in one day. I can't begin to tell you how much stuff I was able to see using this light.

I had decent hopes for this light. But within the first few minutes those hopes quickly faded. It started when I attached it to my weight belt with a key ring and rope through the backend hole. I put the belt around my waist for fitment. As I adjusted the belt I watched the white rubber ring that goes around the on/off button bounce off into the white pea rock in my yard to be lost for good. I looked for it in vein. But thought to myself that if it came off that easy. It might have been a shipping holder or something. Because there’s no way a critical piece of this light would come off that easy.Very first breath-hold dive with it.As I dropped down about 25 feet on my first freedive of the day I tried to look into some ledges , just to check the brightness. It wouldn’t turn on at all. At this time I noticed small bubbles pushing out of the area where the white rubber ring had fallen off. I was not happy. As I headed to the surface bubbles continued to push out of the on/off button area. Then the light actually turned on! But only for a moment. Then off again. I looked into the lens and to my dismay I could see a slight amount of water inside the lens. I dove again and noticed the light had turned on by itself and now I couldn’t turn it off. It’s not safe to have a bright reflective object next to your crotch when diving in the ocean. Knowing this light was officially toast after my second dive I headed for the boat to get my smaller backup light that I luckily brought with me.That was two days ago. I just opened it at home to take a look. The inside of the light is completely rusted and oxidized as the battery leaked and destroyed everything.I won’t even ask for a replacement or my money back. I don’t even care for the $50 or so it cost. Just trying to make note to others before they make the same mistake.

Very good!!

It has a pretty straight beam. That is based on using it in a water filled quarry with 8-10’ visibility. It worked afterwards and we will have to wait for more dives to test durability.
