Core Overview
The SUPERFIRE DL02 is a high-performance professional diving flashlight engineered for extended underwater operations where runtime endurance is equally critical as raw output. Powered by a P50 LED delivering 2000 lumens with a 250-meter beam reach and backed by a massive 5000mAh 26650 lithium-ion cell, the DL02 achieves approximately 4.5 hours of regulated high-mode runtime — a 50% endurance improvement over comparable 21700-powered dive lights. This extended operational window makes the DL02 the preferred choice for technical divers executing long decompression stops, underwater photographers on extended shooting sessions, and commercial divers performing multi-hour inspection tasks.
Built from aircraft-grade aluminum alloy with an IP68 depth rating of 100 meters, the DL02 features the same proven magnetic tail switch, five-mode operation, and four-stage battery indicator system as the premium DL01 series — packaged in a slightly more compact 40 × 36 × 151mm form factor with a 205-gram dry weight. The 26650 cell format provides higher continuous discharge capability and greater total energy capacity, positioning the DL02 as the endurance specialist in SUPERFIRE’s professional diving line for B2B distributors serving technical diving shops, commercial diving contractors, and marine research institutions.
PRODUCT Characteristics
- Extended 4.5-Hour Runtime with 5000mAh 26650 Power
The DL02’s defining advantage is its 26650 lithium-ion cell rated at 5000mAh — delivering approximately 4.5 hours of continuous high-mode (2000LM) output, with proportionally longer runtimes at medium and low settings. This represents the longest single-battery runtime in the SUPERFIRE diving lineup, enabling full-day dive operations on a single charge. The higher continuous discharge rating of the 26650 format comfortably supports the 7.14A peak current draw at maximum output without voltage sag or thermal concerns.
- High-Output 2000LM P50 LED with 250M Beam Range
The P50 LED core generates 2000 lumens of white light at 7000K color temperature, with a 250-meter beam reach through precision-engineered wide-angle optics. Drawing up to 20W input (26.41W peak input power), the DL02 provides substantial illumination headroom for turbid water penetration, long-distance signaling, and underwater photography fill lighting. The optical lens maintains uniform beam distribution across the full output range, ensuring consistent beam quality whether operating at 2000 lumens or at lower conservation modes.
- Glove-Friendly Magnetic Switch with Advanced Mode Memory
The magnetic tail switch operates through the sealed aluminum body with zero mechanical penetration — the same proven architecture as the DL01 series. Five fully independent modes (High → Medium → Low → Strobe → SOS) cycle with a single tap, with dual quick-off features: a single press after 15 seconds of continuous use in any mode returns directly to off, and a 2-second long-press provides instant shutdown from any mode. Mode memory retains the last-used setting through power cycles, saving divers from cycling back to their preferred mode on each activation.
- Compact Form Factor with Dual Battery Compatibility
At 40 × 36 × 151mm and 205 grams, the DL02 is slightly more compact than the DL01 series despite housing the larger 26650 cell. The battery tube is also mechanically compatible with 18650 cells using an optional sleeve adapter, providing logistical flexibility for dive operations that have standardized on the 18650 format for consistency across multiple devices. This dual-compatibility design is particularly valued by dive shops and rental fleets managing mixed battery inventories.

常见问题解答
How do I choose the right SUPERFIRE lighting product for my application?
Choosing the right lighting tool depends on three key factors: brightness (lumens), beam distance, and runtime. For close-range tasks like equipment maintenance, reading, or camping, 100–400 lumens with a wide flood beam is ideal. For mid-range applications such as outdoor patrols, warehouse inspection, or job-site work, 400–1000 lumens with a balanced spot-and-flood beam works best. For long-distance needs — search and rescue, marine navigation, security sweeping, or large-area surveys — look for 1000+ lumens with a minimum 300-meter beam reach. Also consider the form factor: headlamps free both hands for task work; handheld flashlights offer more directional control; work lights with magnetic bases or rotating heads provide flexible hands-free positioning. If you need help matching a SUPERFIRE model to your specific use case, contact our product specialists for a personalized recommendation.
How do I properly charge and maintain the battery for maximum lifespan?
All SUPERFIRE rechargeable products use lithium-ion battery technology with built-in protection circuits. For maximum battery lifespan, follow these guidelines: avoid fully depleting the battery before recharging — lithium-ion cells prefer partial discharge cycles and perform best when kept between 20% and 80% charge; store the unit at approximately 50% charge if unused for extended periods (over one month); avoid exposing the product to extreme temperatures below -10°C or above 45°C during charging or storage; use the included charging cable or a quality-certified USB power source. Every SUPERFIRE unit includes overcharge and over-discharge protection, so the battery is safeguarded even if left connected to the charger after reaching full capacity.
Do you offer customization services?
Yes, we provide comprehensive OEM/ODM services. We can customize appearance, logos, packaging, functional modes (e.g., specific strobe frequencies), and even circuitry according to client requirements.
What quality certifications and warranty do SUPERFIRE products carry?
All SUPERFIRE products are manufactured in our ISO-certified facility and carry international certifications including CE, FCC, and RoHS. Professional-grade models additionally hold IECEx, or IP68 ratings as applicable. Every unit undergoes 100% functional QC inspection covering light output, mode cycling, charging circuitry, and visual defects before shipment. For B2B buyers, we provide manufacturer warranty coverage against defects in materials and workmanship, with spare parts availability throughout the product’s supported lifecycle. Pre-production samples and compliance documentation — including test reports and material certificates — are available for customer review before bulk orders.
Why choose SUPERFIRE over cheaper generic factory alternatives?
While generic factories compete on price alone, SUPERFIRE combines brand-level quality control with factory-direct pricing — a positioning that eliminates the trade-off buyers typically face. Our ISO-certified production line, 100% QC inspection rate, and international certifications (CE, FCC, RoHS) mean you receive consistent, compliant products batch after batch — not the variable quality common from no-name suppliers. Backed by 18+ years of brand heritage (Est. 2008), we offer OEM branding services that let you sell under your own label while leveraging our manufacturing expertise. Simply put: you get the product consistency and compliance of a brand supplier, at the cost structure of a factory-direct manufacturer.
