For recreational and technical divers who want a bright, focused beam that holds up to real saltwater pressure. Submersible to 100 m, glove-friendly, and rechargeable over USB-C.
Long throw for open water and wrecks. At 1,100 lumens with a 788 m beam, the DL30 reaches well beyond the few metres most compact dive lights manage. The focused 3 degree spot cuts through plankton-heavy and silty water, so you pick up a reef wall, a wreck line, or your buddy's signal from a distance.
Made for real diving, not splash resistance. The DL30 is submersible to 100 m, sealed to IP68 with a double O-ring and a thickened tempered glass lens. Nitecore backs the depth rating with a third-party 100 m submersible test certificate, so the number on the box is one that has been pressure-tested.
The throw that finds detail at distance. Turbo runs 1,100 lumens to 788 m at 155,420 candela, dropping to a steady 650 lumen Mid that still throws 612 m for four hours. Spearfishers and night divers get a tight cone that holds its shape underwater, the kind of beam that picks a fish out of a ledge or marks a descent line in low visibility.
Four brightness levels, one simple cycle. Step from 350 lumens for close gauge reading up to 1,100 lumens for a full wreck sweep, all on a single button so you keep one hand free for your line or camera.
Built for wrecks, caves and overheads. The 3 degree spot beam stays narrow and directional underwater, so wreck and cave divers can light a single passage or pick out a tie-off point without washing out the whole space. The same focused cone makes a clear distance signal to a buddy or a surface cover team.
Slip on the diffuser for soft, even light. The included diffuser turns the tight spot into a wide, glare-free flood. Underwater photographers and videographers use it to fill a scene evenly and lift the foreground, and it doubles as an omnidirectional beacon or a soft reading light for gauges and dive computers.
The wrist lanyard keeps it with you. Clip the included lanyard around your wrist for hands-free work on a reel, a camera, or a search pattern, and the light stays put if you let go to deal with your kit.
IP68, double O-ring, pressure-tested. The DL30 is rated submersible to 100 m and carries a third-party 100 m submersible test certificate, so the depth claim is verified rather than assumed. Two spare O-rings come in the box, which lets you swap a seal as part of your post-dive service routine.
Care is simple. Rinse the light in fresh water after every saltwater dive and keep the O-ring grooves clean and lightly greased, and the seal stays reliable dive after dive.
Aero grade aluminium with a hard-anodized shell. The DL30 is machined from aero grade aluminium alloy and finished in HAIII hard-anodizing, the durable surface that stands up to knocks against a wreck and the corrosive bite of salt water. A thickened tempered glass lens with a double-sided coating protects the LED and keeps light transmission high.
Rated for a 1 m impact. Drops onto a boat deck or a rocky entry are part of diving, and the DL30 is impact resistant to 1 m for that kind of routine knock.
Operation you can feel through 5 mm gloves. The single oversized button gives a clear, positive click underwater. Long press turns the light on and off, short press steps through the brightness levels, so you control everything by touch without hunting for a tiny switch or twisting a head.
Flashing modes for team work. SOS plus four flashing patterns at 1,100 lumens give you distinct signals for grouping a team or marking your position in low visibility.
A colour ring around the button shows your charge. The circular power indicator glows blue from 70 to 100 percent, green from 30 to 70, red from 5 to 30, and flashes red below 5 percent. You read your remaining runtime in a glance underwater and plan your turn before the light runs low.
Up to 6 hours on a single charge. The included NITECORE NL2153R 21700 battery holds 5,300 mAh, giving 2 hours at full 1,100 lumens or 6 hours at 350 lumens, enough for a full day of dives at a sensible setting.
USB-C built into the battery. The charging port sits in the cell itself, so you top up with the supplied cable and no separate charger. The 21700 is removable, which means a charged spare gets you straight back in the water for a second or night dive.
Submersible to 100 m, IP68 sealed, and backed by a third-party 100 m test certificate rather than an unverified splash claim.
1,100 lumens and 788 m of throw at 155,420 candela, well past the short range of most pocket dive lights.
A focused 3 degree spot for distance and an included diffuser for an even flood, useful for photo, video and gauge reading.
USB-C built into a removable 5,300 mAh 21700, so you recharge with one cable and carry a spare for back-to-back dives.
Bright, glove-friendly light for night dives and peering under ledges, with a charge indicator so you plan your turn.
A tight 788 m throw and one-handed control, so you keep a hand on your gun and pick fish out of structure.
Clip on the diffuser for an even white flood that lifts the foreground and reduces hot spots in your footage.
High output, long runtime and a focused beam for locating objects and people in low-visibility water.

The DL30 is rated submersible to 100 m and sealed to IP68, with the depth backed by a third-party 100 m submersible test certificate. It works equally well at the surface and topside, so the same light handles a shore swim, a snorkel, and a deep dive.
Yes. The DL30 uses a single oversized button you can feel and press through 5 mm gloves. A long press switches it on and off and a short press steps through the brightness levels, so there are no small switches or twisting heads to manage underwater.
Rinse the light in fresh water after every saltwater dive and let it dry. Keep the O-ring grooves clean and lightly greased, and swap in one of the two included spare O-rings if a seal shows wear. Charge the removable battery over USB-C with the supplied cable.

LOVE THIS FLASHLIGHT. This is my 5th purchase from NITECORE in the past few months. As ALWAYS, build quality is EXCEPTIONAL. I won't be using it as a dive light but it is now my EDC flashlight.

As a professional rescue diver, finding a reliable dive light was always challenging. My previous lights often dimmed or failed at critical moments underwater. The DL30 completely changed that. Its focused 1100-lumen beam penetrates murky waters effectively, significantly improving my ability to conduct search and rescue operations. The robust build, double O-ring seal, and 100-meter waterproof rating provide absolute peace of mind, especially in deep and intense dives. USB-C charging is convenient and reliable. Highly recommended.
I'm a marine biologist, and accurate underwater lighting is vital for my research and documentation. Previously, I faced issues with uneven illumination and frequent battery changes. Since switching to the DL30, my dives are noticeably smoother. The included diffuser attachment provides perfect lighting for photography and close observations. Its durable, corrosion-resistant design holds up well against saltwater conditions. Easy USB-C charging and long battery life save time and simplify my workflow considerably.
