The Helius DH03 is a professional IPX8 diving flashlight engineered for underwater exploration, marine inspection, and night diving. With a 50m 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 15W XM-L2 LED, the DH03 delivers bright, penetrating light for clear underwater visibility. Unlike standard multi-mode lights, it features stepless dimming, allowing you to smoothly adjust brightness from 0% to 100% for precise control in any condition.
The DH03 features a waterproof switch with integrated battery status indicators: white for standby, green for full battery, and red for low battery. This smart design ensures you always know your power status before diving.
Powered by a single 21700 battery (4800mAh), the DH03 offers an impressive runtime of 6 to 12 hours. Weighing only 179g and measuring 136*38*37mm, it is compact and portable, making it easy to carry and operate during extended dives. The bold waterproof rubber ring provides an extra layer of security against water ingress.
