Questions about this product
Which Cameras Will the Ulanzi SL03 Work With?
The Ulanzi Spark Lite SL03 uses a universal single-contact hot shoe. This means it can fire on many cameras that use a conventional hot shoe with a centre trigger contact. Because it is a manual flash, it does not require brand-specific TTL communication
What Comes with the Ulanzi Spark Lite SL03?
The standard Ulanzi SL03 package includes: Ulanzi Spark Lite SL03 Camera Flash USB-A to USB-C Charging Cable User Manual The flash uses a built-in rechargeable battery, so separate AA or AAA batteries are not required.
Why Choose the Ulanzi Spark Lite SL03?
The biggest advantage of the Ulanzi SL03 is portability. At only around 43g, it is considerably smaller and lighter than a traditional speedlight. It can easily remain in a small camera bag or even a pocket, making it ideal for photographers who do not want to carry large lighting equipment. The 90° adjustable head is another important advantage. Unlike many tiny flashes that only point directly forwards, the SL03 can be tilted upward for bounce lighting. When used indoors near a white ceiling or wall, bounced flash can create softer and more natural illumination than direct frontal flash. It also combines a conventional flash with a 5600K continuous LED light, making it useful for both photography and short video or close-up work.
