Powerful Diving Light
The Nitecore DL30 is a powerful diving flashlight with incredible brightness and throw, making it an essential tool for illuminating the depths during underwater adventures. With a max brightness of 1100 lumens and a throw of up to 861 yards, the DL30 can be submersed up to 109 yards underwater, making it perfect for cave diving, scuba diving, or even snorkeling. It also features a 3-degree spot beam angle to provide precise and direct illumination while underwater.
2 Lighting Modes
This versatile flashlight offers two modes: Lighting and Flashing. Lighting mode provides four adjustable brightness settings while Flashing mode includes five options, such as SOS, Quick Flashing, and three frequency settings for various signaling needs. The DL30 also comes with a diffuser, allowing it to double as a beacon or provide softer lighting when required.
Rechargeable and Durable
The DL30 can be charged via its USB-C rechargeable battery that can provide a runtime of up to 6 hours. A circular power indicator is located around the DL30’s power button that will change colors depending on its remaining battery life. Built for rugged underwater use, the DL30 features thickened tempered glass and a hard-anodized finish, giving it an IP68 waterproof rating and impact resistance of up to 1 meter. The included wrist lanyard ensures secure handling during dives, making it an indispensable companion for any diver.

Customer Reviews
While the DL30 has all of the Nitecore attributes of a well-built and solid flashlight, it is very poorly thought out as a dive light. I have been scuba diving for over 30 years, and have used many different dive lights. The DL30 has a max throw of 861 yards, which is nearly a half-mile. For a dive light, this is absurd. Any diver knows that underwater visibility approaching 100 FEET is considered excellent. Even the SUN only effectively penetrates about 220 yards into the ocean (look up euphotic zone). This means that any dive light could only theoretically illuminate an object about 110 yards away, because the light then has to travel back to the diver.
The beam profile on the DL30 is exceedingly narrow. It has a tighter beam than the P30i or the MH40 Pro, which are both marketed as long-throw hunting lights on land. Rather than nicely illuminating a coral reef, a sandy bottom, or the wall on a wall dive, it puts a severe hot spot on whatever it’s pointed at (and completely unusable for any photography).
The DL30 turns on to the full 1,100 lumen output each time, and then needs to be dialed back. Dive lights should come on at the lower output first, so they can be eased up as needed, rather than going from 'off' to shockingly bright right away. Any dive light should also be more of a flood light instead of a spot light, since most divers care about what’s 10 or 20 feet in front of them, and not something they could never see a half mile away.
The threaded diffuser is a nice touch, to ensure that it stays in place while being used. The lanyard holes also allow the pressure inside the diffuser to equalize as you change depth (absolutely necessary). The illuminated power ring surrounding the power button is a nice visual indication of battery life. The removable battery is also a good thing, for quick change-outs between dives, and it also prevents a completely dead battery from requiring that the whole light get replaced.
For the price, it’s not a bad light, but the advertised beam angle of 3 degrees is ridiculous for a dive light. An underwater spot beam shouldn’t be any narrower than about 12 degrees, while an ideal flood beam should be around 60 degrees for good illumination. The best thing this light is useful for is signaling a boat on the surface, or someone on shore, but not as a primary dive light. The photo I took shows the actual beam pattern, with the DL30 in hand. My rating is for the DL30 as a dive light, not a generic flashlight. It seems like the people who designed this have never actually been scuba diving at night (or at any time).
