ORCATORCH D710 Scuba Diving Light, 3000 Lumens Super Bright Underwater Flashlight with 6 Degrees Narrow Beam, IP68 Waterproof Night Dive Torch 150 Meters Submersible Light (Black)

Orcatorch D710 dive light is the best back up light i’ve used so far. It works well during my night dives. Battery lasts long enough for multiple dives in one day and it charges super quick too. I like how it came with a spare battery. It’s super compact and very convenient to use. Not to mention that it matches my gear’s color scheme. I’m glad it was made in a pretty metallic pink :”)

The media could not be loaded. D710:Overview. I wanted a new backup dive light that could be used for a primary in warm clear conditions. A light that could continue the dive if I had my primary fail in the cold dark depths of my home waters in Puget Sound.So how did the D710 do?In the case: It comes with spare o-rings, a lanyard, two 5000 MAH 26700 OrcaTorch branded batteries, a lithium USB charging cable, an instruction manual, a warranty card, and a carrying/storage case. (Boltsnap shown not included)Build and design: It’s built tough. The overall quality feels durable and solid in hand.The titanium alloy button design should keep it watertight.The tube threading is square cut and screws together with ease.The D710 uses an eggshell reflector, which reduces the 6-degree spot effect and provides a blended spot/halo beam.The ribbing and branded orange rubber band look great and provide plenty of grip.Triple O rings for a watertight seal.Depth Rated 150m IXP-8154.9mm x 36mm x 27mmThe button has an LED that indicates the battery level.Green is >30%Red is under 30%Red Flashing is <10%Power and charging: It’s powered by a single efficient 5000 MAH 21700 battery.The light includes two batteries & USB-C cable for charging.No dedicated battery charger is required.Reverse polarity Protection.Over-discharge protection functionStorage Case: Functional soft storage case includedSimple: The light is intuitive and easy to use. Simply click on and click off. From off, one click of the button will bring you to high mode. Another tap will bring you to the medium and then low setting. Holding down the button activates the high setting until depressed.User Interface: * High 3000 Lumens with 1 hour 40 min runtime* Medium 800 Lumens with 3 hours 40 min runtime* Low 400 Lumens 7 hours 40 min runtimeButton Lock Feature: Holding the button for five seconds locks the button. Two quick pushes unlock the light for use.Attachment points: Options for securing. There is a single attachment point on the tail of the light. You can use the provided lanyard or in my case, a 316SS Boltsnap secured with #24 cave line.The Boltsnap was not included with the D710 but Orcatorch does offer one for purchase separately called the SH02 Boltsnap Hook.Beam: The Luminus SST-70 emitter creates a medium-sized throwy 6-degree spot that blends with the halo.3000 claimed lumens on high.Max Runtime 5 hours 45min23750 Stated CandelaColor Rendering Index (CRI) of >706500 Kelvin Color SpectrumFinish: Strong anodizing. The finish shows little wear after multiple dives.Final Thoughts:Pros:•Powerful and high sustainable outputs•Throws light beam very far away•Solid build quality•Perfect Size•On/Off Button makes for easy one-handed use.•Includes TWO 21700 5000 MIH batteries and USB C cable charger. Added value.•Long Runtime allows for multiple dives before needing a recharge.•Bright enough to serve as a primary light on clear-water recreational dives-USB C battery makes for simple charging without needing a dedicated charger.-Intelligent Multiple Electronic Circuit-The ability to go to high mode by holding down the button is a nice and usable feature-battery indicator lighting makes it easy to know when to recharge or change out your cells.-Nice zippered and padded storage case is included.-Good valueCon’s:-No Strobe Feature-If the lock function is neglected the light can easily activate on accident.-It's theoretically possible the button is activated or affected by pressure at depth. No issues to date.-Relatively low color rendering index (CRI) rating >70-Button designs are potentially less watertight than twist-on designs.-I prefer a more pronounced and defined spot. The Eggshell reflector defuses the spot on the D710. I wish it used the smooth reflector the D530 uses.

I own a couple of the Orcatorch handheld lights. My current backup light / every-dive light is the D530. The D710 has a similar switch and lockout feature, but sports 3 (and a special super bright turbo) brightness modes. I like the option for 3, because high is usually too bright for a night or overhead environment dive, but the option to go high and low with the happy medium 800 lumen setting is nice. Cycling through the different brightness modes is easy, as is powering off. I dislike lights that make you do something "seconds" based to shut the light off, where it is easy to lock out or enter an "SOS" mode. This one is simple. Press once: high, once more: medium, once more: low, once more: off. Hold the button from the off position till the light flashes twice and it is locked. The button won't do anything once locked until you press it rapidly twice. There is a battery life indicator led on the button. I never saw anything but green.This light was used on my first Great Lakes dives. The water was cold and the dives were deep. Since the water was so cold (38 degrees F at the coldest), the dives were relatively short. Since the dives were short, I couldn't really gauge the battery life. I had the D710 down to 180 FFW and used it with dry gloves. Even with dry gloves, the button was easy to actuate. I'm looking forward to using it in warm ocean diving, as I believe this is my new "every dive" light, and backup for more technical dives. I would suspect rinsing the button thoroughly with fresh water while actuating after salt water dives will be necessary. But this should be done anyway with special attention to buttons.As for my pictures, my camera battery was acting up (due to the cold), so the two underwater clear photos are all I have. As far as the light warmth and beam, I found it to be softer and perhaps a bit warmer than the D530. I prefer it over the D530, as a super bright center dot is harsh to me. The dot is visible, but not harsh, and the halo is quite full.As for the case, this is the first Orcatorch I've bought that comes with a case. This one has two 21700 batteries included, with room in the case for both batteries. This is great, as even with the lockout setting I'd rather travel with the battery out and the case has room for both. Loose batteries in a bag is not ideal. The batteries charge by USB-C, which is pretty handy. I can have one charging on the boat with a battery pack, or USB from a plug adapter while diving with the other. The battery has a light at the top indicating charging (red) or charged (green). The cable that comes with the light is kind of short, but I'm not going to nitpick that, as these cables are starting to become ubiquitous. Due to the bigger battery than the D530, the light is a bit bigger, and longer. I think the size is quite manageable. Fits in my pocket and has a spot at the end for a bolt snap. I don't tend to use the lanyards, so into the trash that goes.All in all, this light is great and reasonably priced. I wouldn't recommend using it on land, as it gets quite hot on the high mode. I believe it has some circuitry to protect if it gets too hot. This was not possible to test in the cold water I dove it in.
