XTAR SD1 16340 Lantern

The XTAR SD1 is a lightweight, compact lantern built to withstand the rigours of outdoor life while keeping your pack weight minimal. Weighing just 27 g when empty and measuring 23 mm in diameter by 66 mm long, it slips into a pocket or small backpack compartment without adding bulk.

A standout feature is its superior weatherproofing. Tolerating water depths up to 100 m, the SD1 can be hung in driving rain without fear of damage—a level of protection that outperforms many other camping lanterns. When you’re setting up camp in a downpour or deploying a beacon in wet weather, this durability ensures reliable illumination when you need it most.

The lantern offers four colour options—white, red, green and blue—each available in constant or flashing modes. While the light output is fixed and there is no brightness or colour‑temperature adjustment, users find that the clear separation of colours provides enough flexibility for signalling, ambience or night‑vision preservation during low‑light activities.

Battery compatibility gives you flexibility; the lantern accepts either CR123A or protected 16340 cells. With a 650 mAh 16340 battery, you can enjoy up to five hours on white constant light. The impact resistance of 1.5 m means it survives accidental drops from a backpack or when placed on uneven ground.

Overall, the XTAR SD1 delivers reliable lighting in harsh weather conditions without compromising pack weight or convenience. Its main drawback—lack of brightness control—is balanced by its rugged construction and dependable performance in the elements.
