Diving Light Showcase - Nitecore DL10 and Acebeam D20

 

While many flashlights on the market today feature impressive waterproof ratings, most would not last long if taken on a fully underwater task. For that, a diving light is needed. Thorough waterproofing design allows diving lights to operate at greater depths for much longer than ordinary LED flashlights.

As the manufacturers of some of the world's top LED flashlights, Nitecore and Acebeam have taken on the task of making their own underwater diving models. See below for J2LEDFlashlight's "deep dive" on the Nitecore DL10 and Acebeam D20 dive lights.

These lights will reach their limit at extreme conditions and are not suited for extreme or professional grade diving. However, for casual to mid-technical dives, they will go above and beyond in the underwater illumination department. From capturing pictures of a coral reef to scuba diving, they are designed with features ideal for lighting up the watery world around you.

Nitecore's first diving light, the DL10 is specially designed for underwater activities and photography. It features an auxiliary red LED that can be turned on alongside the main LED to provide supplemental soft light for bringing colours out underwater. Two easy to reach side switches let you control both LED modes with ease.

The DL10 is also unique among dive lights by coming with an attachable diving pointer (~165 mm / 6.5 inch), useful for underwater probing and signaling. This diving light is fully submersible up to 30 metres, making it sufficient for recreational diving and photography.

The Acebeam D20 is a step up from the DL10 in terms of raw power. On high it will deliver a peak brightness of 2700 lumens to light up the depths for 2 minutes before stepping down to a still powerful 1000 lumens. The light outputs at a highly focused angle to maximize beam distance. A single side switch allows for easy one-handed control while underwater.

It comes with a micro USB rechargeable 21700 battery, and it is also compatible with 18650 batteries, although performance will be lower. This light is depth rated to 200 metres, making it able to withstand deeper dives.

⦁ LED: 1 x CREE XHP35 LED with lifespan of 50,000 hours
⦁ Max output 2700 lumens when powered by 1 x 21700 rechargeable battery
⦁ Max beam distance: 296 meters (land)
⦁ Peak beam intensity: 22000cd
⦁ Max run time: 7.5 hours
⦁ Two brightness settings plus SOS mode
⦁ Stainless steel side switch for one-hand easy operation
⦁ Included 21700 Battery with built-in Micro-USB charging port included (IMR21700NP-510A battery power bank, 5100mAh)
⦁ Built-in side power indicator
⦁ Ultra-clear tempered glass lens with anti-reflective coating, which achieves a 98.3% light transmittance
⦁ Smooth reflector for max light output
⦁ Highly focused beam for maximum distance
⦁ Digitally regulated output- maintains constant brightness
⦁ Over-heat protection to avoid high-temperature of the surface
⦁ Aircraft grade aluminum body structure, premium type III hard anodized anti-abrasive finish
⦁ Depth rated submersible to 200 meters
⦁ Impact resistance: 1.2 meters
