ThruNite TH20 520LM Rechargeable LED Headlamp – Compact Power for Everyday & Outdoor Use
The ThruNite TH20 is a lightweight, high-performance headlamp designed for camping, hiking, DIY tasks, night running, and everyday carry. With up to 520 lumens and a 67 m beam distance (with 14500 battery), it offers both powerful illumination and soft, diffused light for close-up work such as reading, tent lighting, or gear checks.
Featuring a Cree XP-L V6 LED and an orange peel reflector, the TH20 produces a wide, floody beam that reduces glare and hotspots, making it comfortable for extended use. The intuitive side switch gives you instant access to Firefly, Low, High, Turbo and SOS, plus smooth, logarithmic brightness adjustment so you can dial in exactly the right amount of light for your task.
Power is flexible and convenient: use a common AA battery (NiMH/alkaline) for up to 250 lumens, or a 14500 Li-ion cell for the full 520-lumen output. This versatility makes the TH20 ideal for travel and emergencies, as AA batteries are easy to find anywhere. With Firefly mode at just 0.3 lumens, you can get up to 60 days of continuous runtime, perfect for preserving night vision or use as an ultra-long-lasting emergency light.
Built from aircraft-grade aluminum with a Type III hard-anodized finish, the TH20 is tough enough for demanding outdoor conditions. It is IPX8 waterproof (submersible to 2 m) and impact resistant to 1 m, so you can rely on it in heavy rain, on the trail, or in the workshop. The compact body (100 mm x 24 mm x 24 mm) and low weight (76 g without battery, about 96 g with) ensure all-day comfort and easy packing in a bag or kit.
The included adjustable headstrap with soft rubber holder keeps the light secure and comfortable on your head, leaving your hands free for climbing, setting up camp, fishing, repairs, or emergency situations. Neutral white and cool white versions are available so you can choose warmer, more natural tones or a cooler, crisper beam depending on your preference.
