The Helius DH05 is a professional IPX8 diving flashlight engineered for underwater exploration, marine inspection, and night diving. With an impressive 100m depth rating and a durable aluminum alloy body, it is built to withstand the pressures of deep water while delivering reliable illumination.
Equipped with a high-performance SFT40 LED, the DH05 delivers 2000 lumens of bright, penetrating light. Whether you are navigating a wreck, checking reef structures, or working in murky conditions, the focused beam cuts through the dark water for clear visibility.
The DH05 features a waterproof switch button with integrated battery status indicators: white for standby, blue for full battery, and red for low battery. This smart design ensures you always know your power status before diving. A bold waterproof rubber ring provides an extra layer of security against water ingress.
Powered by a single 21700 battery (4800mAh), the DH05 offers an impressive runtime of 6 to 12 hours. It supports multiple modes including High, Mid, Low, and SOS, with a convenient long-press to turn off from any mode.
