DH1 is a reliable, affordable, purpose-built spearfishing light. It cuts through murk, reaches deep into caves, and lasts a full dive — and then some. If you need a video light, look elsewhere. If you need a no-nonsense hunting light that does one job well, this is it.
FAQ for XTAR DH1 1600 Dive Light
The DH1 1600 combines three features critical for successful spearfishing: (1) 5° ultra-narrow beam concentrating 1600 lumens into a tight cone that penetrates murky water and dark reef crevices; (2) 355m throw enabling long-distance scanning of kelp edges, sand patches, and structure before committing to a dive; and (3) mechanical locking switch preventing accidental activation during gear transitions or when wedged against rocks in tight spaces. Spearfishers consistently praise its build quality and performance in real-world hunting conditions.
The DH1 features a two-stage mechanical lock: rotate the switch collar to the locked position, and the button is physically blocked from depression. Unlike electronic locks that can fail due to water intrusion or battery depletion, the mechanical lock is immune to electronic faults. This is essential for spearfishing, where the light is frequently clipped to harnesses, stowed in kayak hatches, or wedged against rocks during lobster extraction. Accidental activation in these scenarios drains batteries and can spook target species.
Yes. The DH1's extreme throw (355m) and narrow beam make it effective for cave line following and wreck penetration where long sight lines are common. Always carry a backup light in overhead environments.
The DH1 uses a single 21700 Li-ion battery (included), providing up to 2.5 hours runtime at maximum output. Compared to 18650, the 21700 offers 30–40% more capacity in a similar form factor, reducing battery swaps during multi-dive days. Compared to 26650, the 21700 is more compact and widely available globally—critical for spearfishers traveling to remote destinations. The DH1 does not accept 18650 or 26650 due to physical size constraints.
Yes. The DH1's Type III Anodized Aluminum Alloy Casing resists saltwater corrosion and biofouling accumulation. Double O-ring seals maintain IPX8 integrity through daily rinse cycles.
