Key Product Advantages
- IP68-Rated Deep-Water Performance
The DL01 is rigorously tested and certified to IP68 waterproof standards, withstanding sustained submersion at depths of 100 meters (328 feet). Double O-ring seals at every junction point, precision CNC-threaded end caps, and a reinforced lens assembly ensure zero water ingress under sustained hydrostatic pressure. The magnetic tail switch eliminates mechanical penetration points — a critical engineering advantage over traditional push-button designs that degrade under pressure cycling.
- High-Output P50 LED with Precision Optics
The P50 LED core generates 1400 lumens of pure white light at 7000K color temperature, cutting through turbid water with a 270-meter beam range. The high-transparency optical lens is engineered with a wide-angle beam profile that provides both a concentrated hotspot for long-distance object identification and sufficient spill for peripheral awareness — essential for underwater navigation and buddy visibility.
- Glove-Friendly Magnetic Switch with Mode Memory
The magnetic tail switch requires zero mechanical travel — a simple tap or press cycles through modes even with 5mm or 7mm neoprene gloves. Five fully independent modes (High → Medium → Low → Strobe → SOS) are accessible in sequence, with intelligent mode memory that recalls your last-used setting. A long-press (2 seconds) instantly shuts off the light from any mode, eliminating the need to cycle through all settings. After 15 seconds of continuous use in any mode, a single press returns directly to off — a time-saving feature for frequent on/off diving tasks.
- Aircraft-Grade Aluminum Construction
Machined from T6061 aluminum alloy billet and treated with a military-grade Type III hard anodized finish, the DL01 withstands the corrosive effects of saltwater, high humidity, and repeated pressure cycles. The body exhibits excellent thermal conductivity, effectively dissipating heat from the LED even during extended high-mode operation — a critical performance characteristic that cheaper polymer-body diving lights cannot match.
- Intuitive Battery Status Indicator
A four-stage LED indicator ring provides real-time battery state: blue (80–100%), green (40–80%), red (10–40%), and flashing red (below 10%). This eliminates the guesswork of underwater battery management — divers can assess remaining runtime with a single glance and plan their ascent accordingly.

常见问题解答
How does the DL01's magnetic switch compare to a traditional mechanical switch for diving?
The magnetic switch is a superior solution for diving applications. Unlike mechanical switches that rely on physical penetration through the body (requiring dynamic O-ring seals that degrade over time), the magnetic switch operates through the sealed aluminum wall with zero moving parts exposed to water pressure. This eliminates the most common failure point in diving lights — switch seal degradation. Additionally, the magnetic actuation requires no finger dexterity, making it operable with 5mm or 7mm neoprene gloves, in cold water, and under high pressure where mechanical buttons can become stiff or unresponsive.
What is the actual burn time at each brightness level?
In controlled laboratory testing using the included 21700/3000mAh cell at 25°C ambient temperature: High mode (1400LM) delivers approximately 3 hours of regulated output before stepping down; Medium mode provides approximately 8–10 hours; Low mode extends to 20+ hours. Strobe and SOS modes, due to their intermittent activation patterns, can operate for significantly longer. Actual runtime varies with water temperature (cold water accelerates battery discharge), battery age, and charge cycle count.
Can the battery be replaced underwater or while wearing gloves?
The DL01 uses a single 21700 lithium-ion cell accessed through the tail cap. While the battery is user-replaceable, we do not recommend opening the flashlight underwater or in humid marine environments, as moisture on the O-rings or threads can compromise the seal upon reassembly. For multi-dive sessions, we recommend charging between dives or carrying a second fully assembled DL01 unit. The tail cap threading is coarse-pitch for quick operation and features anodized threads to prevent galling.
What is the beam pattern — spot, flood, or hybrid?
The DL01 employs a fixed-focus wide-angle optical lens that produces a hybrid beam pattern: a defined central hotspot for long-range target identification (effective to 270 meters in clear water) combined with a graduated spill beam that provides approximately 60 degrees of peripheral illumination for situational awareness and buddy tracking. There is no adjustable focus mechanism — the fixed design eliminates a secondary water ingress path and ensures consistent beam quality at all depths.
What maintenance is required to ensure long-term waterproof performance?
After each saltwater dive, rinse the DL01 thoroughly in fresh water with the tail cap fully tightened. Periodically (every 10–15 dives or before extended storage): remove the tail cap, carefully extract the O-rings using the provided O-ring pick, clean the O-ring grooves with a soft brush and fresh water, inspect O-rings for cuts, flattening, or cracking, apply a thin layer of silicone grease (included in the spare kit) to each O-ring before reinstallation, and lubricate the tail cap threads lightly. Store the flashlight with the tail cap slightly loosened to relieve O-ring compression during long-term storage. Replacement O-ring kits are available from SUPERFIRE and authorized distributors.
