Aramox Diving Flashlight 18000 IPX8 Dive Lights 500M Underwater LED Flashlight Submersible Lights for Outdoor Under Water Sports

UPDATE! Lasted 4 years before button failure. Everything else seems fine, tho i can't replace the buttons easily. Just gonna buy it again.---Its been over a year now!Blindingly bright! Very solid build.Absolutely needs to be underwater while in use for more than a minute. It was accidentally turned on in my bag and it melted some of the plastic around it. Maybe a V2 of the light should have recessed buttons for safety.As others have said, batteries with the raised positive ends are needed. I couldn't find any but i had tiny neodymium magnets handy and that works surprisingly well. Like i thought they'd slide off but they don't.Lubed up the threads upon receiving and have taken it down to 50ft many times without problem. But i also haven't had any QC issues so YMMV.

I used this for underwater photography as a flood light for my 10-day diving trip so I used it at up to 25m depths over 20-30 dives.Great flood light, could illuminate a large area enough so it's even lighting when I take pictures of critters. Works at depth, very bright, choice of colors (to try to counter the blue shift underwater) and level of lighting. Also the red light was helpful since some sharks are insensitive to red light and you can get a good look without scaring them.On the down side at the highest white-light setting it was so bright it seemed to disturb my subjects, so use it with care for marine species! [I used only the lower levels unless I needed the bright light and only for short periods too much to the light]Also make sure you recharge after every dive, the batteries don't last long at this level of output!Like others at first I didn't know how to open it. It opens at the base of the wider part like other flashlights but it's VERY tight, so we had to screw on the handle and then use the handle to open the battery area.Enjoy!

This is a great little light. I use it for all applications. It’s a fog style so its really wide angle. Underwater work great for clear water and cave diving. It does not work well in murky water like Gulf of Mexico because the particles in the water pick up the light and I cant see anything since its so wide angle. I like my 10 degree light for spearing. I took this bad boy into a cave in florida and its perfect. The only flaw I found was that people reported it would randomly turn off and it did this to me as well. I found out that you have to put an extreme amount of force twisting it closed otherwise it will turn off while using. Just fyi.

Do not buy. In short, not the product listed and broke within ten minutes of 'on time', never even saw outside the house.Taking it out of the box you can tell that the casing is pretty well built, but you can also see quite clearly that the electronics parts were cheaply manufactured and assembled. In fact, in the lense there were soldering waste loosely banging around and the led modules aren't even in the same orientation as in the images on the listing. Inserted my newly bought 18650 batteries that cost just under the amount of the flashlight, and quickly realized the sun was in the palm of my hand. Turned it off after figuring out the buttons, maybe two minutes of "on time" total. The next day turning it on was a failure, almost. I had to smack the thing against my hand for a few minutes to change the light from flickering to on. After this, it worked for about ten minutes when I turned it back off. Charged the batteries again for good measure, and now I am on four hours of pretty consistently attempting without success to turn the thing on at all.Picture one is the proof that you aren't getting the flashlight you bought, and pic two shows the soldering waste in the lense, which is represented by the two noticeable grey flecks.

These flashlight are awesome. Great switch design is extremely water proof. Perfect for night diving. The two color flasher is also a great safety feature. Looks like a police officer. This will get somebodies attention fast in an emergency. It must be stressed that these lights need to run submerged underwater when running in highest intensity, otherwise it could easily start a fire. Always remove at least one battery for shipping and above water transport (like in your car trunk). This is the best flashlight ever built.

Purchased to replace the last one I had for 5 years before it flooded on a dive. This light withstood the pressures well below 130fsw. Definitely recommend this light if you’re on a budget.

I have more than my share of dive lights ranging from big name ones to cheap imitations, this one is by far the best.******It uses button top batteries******I put it in a bucket of water and let it sit, it has a usable light runtime of about 45 to 50 minutes on full, 70 minutes on the next lower setting. The included handle was too small for my dry gloves so I modified a soft hand light mount and it worked perfectly.The beam is wide and even which makes it great as a video light and the buttons require some pressure to push so the light won't turn on in your pocket.. The slot for the handle is a standard photo mount size so it can be used above water as well.I saw some comments about cross threading issues but its no different then any other light. It has a double o ring seal and includes extra o rings, I have no fears of it flooding at depth.Only thing I wish it had was a loop for a lanyard
