Sofirn SR23 21700 Torch

The Sofirn SR23 Dual Light Flashlight is a high-performance, multi-functional EDC tool designed for users who demand reliability, versatility, and premium build quality. It stands out in the crowded flashlight market by combining a powerful 3300-lumen white floodlight with a dedicated 365nm UV light—offering applications far beyond standard illumination.

The light’s primary white output is delivered via three high-efficiency TN-3535 cool white LEDs, each paired with a TIR (Total Internal Reflection) optic to produce a smooth, wide flood beam. This beam pattern is ideal for illuminating large areas such as campgrounds, emergency scenes, or indoor spaces. The 365nm UV emitter, while smaller in size, is engineered for strong, focused output—perfect for detecting fluorescent substances like scorpions, urine trails, or counterfeit banknotes. The absence of a ZWB (UV blocking) filter means the UV light is fully unfiltered, maximising intensity for detection purposes.

Operation is intuitive thanks to the dual side switches—one for the white light, one for the UV light. Each switch provides stepless dimming via a smooth ramp function, allowing users to adjust brightness seamlessly from near-total darkness to full turbo. The regulated driver ensures consistent output across the entire battery range, preventing brightness drop-off as the battery depletes.

The USB-C charging port is located at the base and features a thick, durable cover that stays firmly in place. The charge status is indicated by a red LED during charging, turning green upon completion. A full charge takes approximately 1 hour and 40 minutes.

While the light performs exceptionally well overall, some users may notice a greenish tint in the white beam, especially at lower outputs. This is due to the specific emitters used (TN-3535), which are rated at 6500–7000K but measure closer to 5500–5700K with a slight green bias. While the light is efficient and bright, users seeking warmer, higher-CRI (Colour Rendering Index) white light may find this less ideal. However, for tasks requiring high visibility and wide coverage, the brightness and beam quality more than compensate.

Despite this, the SR23 excels in real-world use. Whether you're camping, hiking, doing night-time inspections, or preparing for emergencies, the combination of a powerful white floodlight, a functional UV light, and a robust, user-friendly design makes it one of the most versatile EDC flashlights available.
