Finally had a chance to use this this past weekend on a dive. Followed all the instructions and charged fully before getting to the dove site only for this to be completely USELESS as it does not turn on. Buyer beware!!! Do not buy. Just had to replace it because it is a hunk of junk!

Solid flashlight with waterproof switch and intuitive controls.The GoZebra D20 flashlight is designed to be used underwater but is a good general-purpose EDC flashlight as well. The unit uses a single, high-capacity 3200 Mah 18650 cell. Operation is dead simple with button presses giving increasing light levels and a long hold button push to turn the light off. You can also do a quick double press to lock the light out while being transported. It comes with the 18650 battery included, a charging USB C cable, extra silicone O rings, and a diving lanyard.The unit is charged with an internal USB C port which is water sealed by the tail cap. The body is very smooth and could have used some knurling for a better grip but the long lanyard cord will keep it attached to the diver. The bottom tail cap is perfectly level so it can be used as a stand-up lamp if desired.Build quality is good with a solid, thick-walled aluminum body and hardened mineral glass lens. See the attached pic of it easily supporting a 40 lb weight on one end. All in all an excellent light.

This is the third Chinese dive light I have bought from Amazon and by far the best. I had a 2500 lumen and 5000 lumen that were barely different in brightness. But this one, rated at 13000 lumens is BY FAR BRIGHTER than the others and with the discount less expensive than the others. Is it really 13000 lumens? I have no idea.It uses TWO 5000mah batteries, which gives it its brightness. Its 8 inch length is perfect IMO and makes it easy to hold underwater. A nice feature is you hold the button to turn it off, and it turns back on at the brightness level it was at when you turned it off-you don't need to cycle through all the brightness levels.The beam is a little wider than the others, about as white, but MUCH brighter.It's durable and weighty with the batteries installed, heavy in a good way, not too heavy. I wouldn't want to get conked on the head with it!Comes with everything as advertised.I recommend it, you won't regret it.

Good little light that is bright enough to use under water even in the daytime as well as a great light for night dives. I only gave it four stars because the push button switch is too easy to turn on inadvertently, especially when you put it in a pocket. This is a problem during day dives when I don't realize it is turned on. It is not a problem during night dives as I turn it on and leave it on the entire dive. Charged battery lasts throughout a one hour night dive.

I purchased this light to take on a camping trip in August because I needed a rechargeable waterproof flashlight and this light fit the bill. The lowest mode on this flashlight was way brighter than my uncle's trusty O'l Maglite and way more compact (not to mention rechargeable and waterproof). I have been using it around the house ever since, it's been very useful for checking the yard at night while letting the dogs out, as well as taking my dogs for a walk.The D10 has become my new favorite flashlight. If you're involved with a job/ task that deals with wet situations this is a great option because it's waterproof. I submerged it in a 5-gallon bucket of water and left it sitting in the lowest setting and 4 hours later this flashlight was still running. This light performed flawlessly. When you switch this light into the highest setting, it's like having a piece of the sun in the palm of your hand. The Cree XHP 70.2 LED used in this flashlight is a serious powerhouse that is capable of punching out 4500 lumens. This LED provides a warm light mimicking the color of daytime. It's very useful having a piece of the sun in the palm of my hand. The included 21700 battery (size of battery) is rated at 5000mah (amount of juice on the battery) providing great run time. The 4-hour run time claimed is accurate. The low setting on the Gozebra D10 can stay illuminated without getting hot, giving its user up to 4 hours of light for whatever application is needed. However, on medium or high it does get quite warm, but with the built in ART technology, it will automatically kick the brightness down to prevent overheating.The D10 would make a great choice as a primary or secondary flashlight while diving (always carry 2 flashlights). Given its sleek compact design, weighing in at just over 9oz, about 5 and 1/2 inches long this flashlight can be easily placed in a bc pouch or wherever desired. The amount of power coming from this flashlight will surely gain the attention of fellow divers, if needed. The Gozebra D10 is equipped with double silicone O rings and comes with well-greased threads on both ends that provide a tighter seal allowing for better waterproofing, ensuring that your flashlight stays dry. The Rotary switch design (L, M, H) makes one handed use very easy. The lanyard that comes with this light fastens securely to the tail cap. The orange peel reflector projects a very nice beam of light with a good amount of flood (the amount of light surrounding the lighted area) with a good amount of throw (the distance the light is projected) making this light a great option.I own a few flashlights that I use regularly around the house, and I must say the D10 is one that I've been grabbing ever since I received it. The Gozebra D10 is a great flashlight for everyday use and would make an excellent choice as a primary or secondary dive light.
