1Pc Underwater Strobe Signal Light Scuba Night Dive Marker LED Flashy Safety Lamp Firefly Diving Beacon Beam 200M Underwater 200 Hour Duration with Battery -White

Used this for a number of night dives during a dive trip to the Bahamas. Unit worked fine, and came with two batteries which was nice. I don't believe we dove deeper than 40 feet, so I can't attest to it's reliability at depth. I didn't have any failures in terms of it being water tight. It's not the brightest light by any measure, but it served its purpose and was worth the price. I also liked not having to throw away cyalume sticks after a couple uses.

Worked great at 40 feet for 37 min night dive in 65 degree F. LED is not super bright, but enough to identify dive buddy. Lanyard connection looks a bit weak, but there are multiple eyelets. I used a regulator mouthpiece zipties to secure it. Comes with extra battery.

Good product. Worked well on two dives. Only complaint is that after it warmed up it turned back on. Caught it when I got home but after you rinse it give it another hair turn so it doesn’t turn back on.

I thought it would have a longer lanyard or leash. The spare batteries are great to have. And some clown couldn't figure out how to install the batteries. The picture shows the batteries + side up. And there only 2 choices as to how to install them. So what if it was a 50/50 chance.

The light is very damn and virtually useless even with night diving in Clearwater. I'm not going to spend $6 to return a $9 light

Very small and not very bright blue light. Have not dove with it yet to get feedback from fellow divers as far as visibility. I'll keep you posted.

It's too small, not bright enough and not useful for diving at all. Use it on your key chain. I'm sorry I did not get to return it

What can I say it does what it's supposed to do it lights up flashers.

Purchased two of these for liveaboard last year where we new we were doing some night dives. Tested in the UK worked fine both, first night dives, one would not turn on and second one failed after 20 mins into dive.

Just back from a dive holiday in Egypt. The product worked well and is good value for money. It also came with a spare battery, which I did not expect. This is a good product for night dives or wreck dives in order to make it easier to distinguish between divers and also to see that that there are divers ahead.

I bought this to attach to my diving gear but it is almost invisible except at night when it is barely useful. It does not strobe and is definitely not a safety lamp.

Very hard to turn on and off with even slightly damp hands. Light hardly visible even at short distance unless in total darkness. Poor build quality. Would certainly NOT recommend to anyone.

Both Strobe lights failed after 1st dive1 Flooded due to a very poor design in O-Rings1 Never turned back on after 1st Dive even after changing the batteriesI'd avoid these if you don't want to waste you money
