Offering 600 lumens and depth rated below 600 feet, the DGX 600 Handheld Light features a true out-the-front 600 system lumens (1100+ raw LED lumens) of cool white 6500°K light in a tight 8° beam. Twist the light head portion for ON/OFF activation with a triple O-ring seal. Using the supplied lithium-ion 18650 rechargeable battery, this compact light has a burn time of about 60 minutes . According to CREE, the DGX 600 has one of the highest performing single-die LEDs that is commercially available, the XLamp XM-L2 U2 LED, and is single-mode driven to prioritize light output over burn time. We are not exaggerating when we say this handheld light throws more punch than many of the previous generation of canister primary lights in the water today. Considering the Dive Gear Express price, durability and light output the DGX 600 represents an excellent value!

Incorporating an optical quality glass lens with a triple o-ring seal between the head and body, the light is IP68 rated to { 656 ft | 200 m }. The switch design is twist ON/OFF at the head; unscrew the head completely from the body to load the battery. We designed this light with very tight tolerances to ensure the extreme depth rating so you will notice the activation does take effort. The tail has a sturdy rear tie-point for a bolt snap or use the included lanyard. The light has an electronic circuit to maintain constant light output as long as possible and provides reverse polarity & over temperature protection; meaning the DGX 600 can also be used briefly as a dry flashlight on the surface. Use the TTI-1004 Generic Mounting Bracket (Small) for helmet mounting this light. The anodized aircraft aluminum body measures { 5.3 x 1.6 x 1.4 in | 135 x 40 x 35 mm } (length x head diameter x tube diameter) with a dry weight of { 8.4 oz | 238 gm } including the battery.

In The Box -- The DGX 600 TWIST light head and triple O-ring seal body with three O-rings pre-installed on the body, plus a lanyard and a set of three spare O-rings. The package also includes a lithium-ion 18650 protected 3.7V battery and 110/220V 50/60Hz mains charger with US flat blade plug on the power cord - an EU round mains plug adapter is available separately.

There isn't a manual, however there is not much to know. To load batteries, unscrew the head from the body until the two pieces separate and then insert the batteries in to the body, negative end first such that the positive end will be pointing toward the light head. Hold the head and screw the body clockwise back together all the way until it stops. To turn off, twist the body counterclockwise until the light goes off then continue to twist the body one half revolution. Once assembled, the twist-on light should require a maximum of about one full revolution to turn on or turn off. If the O-rings look dry, leave them in place but smear a very small amount of silicone lubricant on the part of the O-ring surface you can see. If the O-rings start looking flat, then replace them with the included spares. Do not store the light for extended periods with the batteries remaining inside the body. You might also benefit from reading How to Use a New Twist-On Handheld Dive Light.

The DGX light includes a generic battery and charger, but any good quality protected-type 18650 battery and charger is suitable. They all pretty much work the same way and are interchangeable. Some batteries ship with a small adhesive cover on the ends or a sealed with a clear (not blue) plastic shrink wrap, if so remove and discard. Place the battery in the charger, matching the positive and negative indications on the sides of the battery to the same indications on the charger, and then plug in the charger. If the battery is properly positioned in the charger, a red light will illuminate and then some time later change color to green when done. Charging time varies considerably depending on the pre-existing charge level of the battery, typically 2 to 3 hours but can be as long as 4 to 6 hours for a depleted battery, and it's normal for batteries to get warm while charging. Best practice is never leave charging unattended then once the light turns green, unplug the charger and remove the battery.

Burn times with the supplied battery are a conservative estimate for technical diving use. Burn times can vary widely because we observe that most brands of lithium-ion 18650 batteries grossly over state their power rating claims.

Light is brighter than other ...
Oct 6, 2023
Light is brighter than other "higher lumen" advertised lights. I found this 600 lumen light to be brighter than my other lights that were supposedly 800-1000 lumens. Easy to use by twisting and comes with all the chargers and accessories you need. I've never had it accidentally turn on by getting bumped. The beam is narrow (8 deg) and pierces better than wide beam lights. I take this light with me on every single dive I do.

This is my first DGX ...
Aug 30, 2020
This is my first DGX brand light. Up until now I have only used LED lights powered by off the shelf disposable batteries. While they do offer flexibility if your batteries die at an inopportune time or location, they leave some room for improvement in the brightness category. I currently own two Princeton Tec LEDs. One uses 8 c-size batteries and the other uses 4 AA-size batteries. While both are very bright and have served me well, they both have negative aspects. The larger light is heavy and bulky. The smaller light is pretty handy in size and power, however it’s plastic and it could easily be crushed or cracked in a gear locker or on the dive boat. I snagged the DGX 600 and I do not regret it. I tied a snap to it tec/caver fashion. The entire light is built like a tank. It’s made to last the test of time, the worst a cave can throw at it, or the rigors of tec diving. The threads engage easily and appear to be machined to very tight tolerances. The o-rings definitely engage the light head and provide a very secure feeling when twisting the light on and off. This light isn’t going to accidentally unscrew itself. I do wish there was a way they could provide a positive click at the very end to know just where the “break” is for on and off. I dove a rock quart this weekend and started off with my larger 3 led Princeton Tec 8-C light. After 50’ it gets dark down there. The PT cut the darkness with ease, but man what a heavy light. I switched to the DGX and what a difference. The beam is tight and very bright. The light output was on par, maybe even brighter than the 3 LEDs on the bigger light. The form factor is much easier to use as well. Clipped off to a ring on my BC, this light isn’t nearly as cumbersome or clunky as that big light cannon. Overall, I’m pleased with this light. I plan to buy the DGX 800 and run it as a primary (I don’t do a lot of night diving).

Good price, great light
Mar 6, 2020
What a great light. I've had and tried several others, but this DX600 is a good size, great light output, and pretty good battery life. I liked so much that after a few years bought a second one as a back up.

Best compact dive light for the money
Jul 4, 2019
I’ve bought several compact dive lights and this is the best one for sure. The rechargeable batteries are readily available and the same ones I use in my headlamps for nightly chores. It is rugged and durable. The beam is well designed with a wide enough flood portion and a very bright central spot beam. I bought a push button as well but prefer the twist to turn on version.

Great Light
Apr 16, 2019
The DGX 600 TWIST is a great light, I have two of them. Bright enough for recreational diving in Puget Sound's dark waters, lite-weight and easy to pack. I also own the DGX 800, which is slightly brighter and uses two batteries, but I actually recommend the DGX 600 instead. The difference in brightness between the 600 and 800 is not very noticeable, and the failure modes are also different. When batteries get low, the DGX 600 starts to dim, but you probably won't even notice it on an hour-long dive and fully-charged battery. The DGX 800, on the other hand, demands a minimum voltage level or it starts to cut out; when one or both batteries get low or old, the 800 has a stroboscopic failure mode until it goes out entirely -- a problem I haven't seen with the DGX 600. The DGX 600 is really a nifty little light.

  • The DGX 300 Mini Light features a true out-the-front 300 system lumens (600+ raw LED lumens) with 30 minute burn time using a rechargeable 14500 battery. Using a quality AA size disposable alkaline battery you will get about double the burn time with half the lumens.
  • The DGX 600 Handheld Light features a true out-the-front 600 system lumens (1100+ raw LED lumens) with 60 minute burn time using a rechargeable 18650 battery.
  • The DGX 600 Button model is also available in a VIDEO version that features a diffused no-hot-spot 120° beam perfect for use with underwater video, but is otherwise identical to the tight 8° beam version.
  • The DGX 800 Handheld Light features a true out-the-front 800 system lumens (1100+ raw LED lumens) with 90 minute burn time using two rechargeable 18650 batteries.
  • The DGX 800 has a longer body incorporating two batteries means the increased power of the DGX 800 is 30% brighter with 50% longer burn time.

The DGX 600 is available in your choice of BUTTON or TWIST style activation. The choice between twist-on or button-on styles is mostly a matter of personal preference, although the TWIST version has a ultra deep depth rating. If you are mounting the light, we recommend the BUTTON style. If the light is being carried as a handheld backup to a primary, we recommend the TWIST on style.

Various LED dive light suppliers use different methods of determining light output, plus expressing them in different forms of measurement. What matters is the visible light from the LED that bounces off the reflector and passes through the lens. The quality of the reflector and lens, as well as the actual amount of power delivered by the battery have a major affect on the amount of light that reaches the target. Dive lights would be better described by the system lumens (sometimes called out-the-front or OTF lumens), which is the amount of visible light emitted by the entire system of battery, bulb, reflector and lens. Describing any LED dive light in terms of the radiant lumens specification of the entire light output for a raw LED module (including IR and UV wavelengths we can't see) at maximum power under laboratory conditions can be very misleading. Unfortunately we have to mention the radiant lumens value because most other dive light suppliers use only the bigger number to inflate their descriptions.

The DGX800 light has a driver working voltage from 3.0V to 13.0V, and thus is suitable for use with its two battery body. Our DGX600 series light heads have a working voltage on the LED driver of 3.0V to 4.2V, suitable for their one battery body. Although they look similar and will fit together mechanically, the DGX600 light head must NOT swapped on to a two battery body. If you mount a DGX600 light head on a two battery body, the electronics in the DGX600 head may burn out and then light will no longer come on.
