Ulanzi SL01 | SL02 | SL03 Spark Lite Camera Flash Light
The Ulanzi Spark Lite series—SL01, SL02, and SL03—are ultra-compact, USB-C rechargeable camera flashes designed for portability and everyday use. All three offer a guide number of 8 (ISO 100), 4 power levels, and are compatible with most cameras via a universal hot-shoe. The SL01 is a basic flash-only model, ideal for minimalist shooters. The SL02 adds a constant LED fill light (1W, 5600K, CRI 95), making it suitable for both photos and video. The SL03 is the most advanced, featuring a hybrid mode (flash + LED), a tiltable flash head for bounce lighting, faster recycling times (as fast as 0.8 s), and a higher CRI of 97, offering more creative flexibility for photographers and content creators.
