Ulanzi SL03 Spark Lite Camera Flash Light(White)

The Ulanzi SL03 Spark Lite Camera Flash Light (White) is a pocket-sized external flash with a built-in constant LED light for cameras with a universal hot shoe mount. It offers manual power settings from 1/1 to 1/8, a flash color temperature of 6500 K, a 90° tilting head, and a rechargeable battery with a capacity of up to 500 full-power flashes.

The SL03 Spark Lite is a compact flash unit for creators who want to keep an external light source in their bag or pocket at all times. Weighing just 43 g, it doesn’t add much weight to a small camera setup, yet it offers significantly more controlled lighting than a camera’s built-in flash.

The flash operates in manual mode and offers four power levels: 1/1, 1/2, 1/4, and 1/8. This is useful for portraits, close-ups, product photography, or indoor snapshots where you want to add light without a large system flash.

The flash head can be tilted up to 90° upward, so indoors you can bounce the light off the ceiling or a wall to achieve a softer result. The integrated constant LED light can serve as an auxiliary light, a focus light, or an emergency light for short videos.

The built-in 300 mAh battery charges via USB-C and, according to the manufacturer, can handle up to 500 full-power flashes. Its compact design and simple controls make the SL03 a practical accessory for travel, street photography, everyday shooting, and light product photography.
