The Ulanzi LM25 is a small 50 g LED light that snaps onto the DJI Osmo Nano or Osmo Action 6 with a magnetic quick release. The mount works on both sides, so another module can go behind the light. It offers four colour temperatures from 2900 to 6700 K, CRI 90–94 and flicker-free PWM dimming, and runs up to 14 hours at the lowest level. Side 1/4″ thread, magnetic back.
The Ulanzi LM25 clicks onto the DJI Osmo Nano or Action 6 in one move, so the light is always right next to the lens – for close-ups, low light and travel.

Both the front and the back of the light have a quick release mount that fits DJI Osmo Nano and Action 6 cameras. You can put the light between the camera and another module, such as a display or a neck mount, and the setup stays compact.
Even light on your face.
Fill light after sunset.
Close-up details without shadows.
Snaps onto a phone by its back.
Both magnetic mounts fit the quick release system of DJI Osmo Nano and Action 6 cameras. Add another module behind the light, such as a display, a cap clip or a neck mount. Press the light on gently until the mount clicks into place.

A 1/4″ thread on the side lets you put the light on a handle, mini tripod or extension pole. Useful when you want the light away from the camera to light the scene from another angle.

The silicone back pad hides a MagSafe magnet. Attach the light to a flat metal surface or to the back of a MagSafe phone; other phones need a magnetic ring (sold separately). On a phone, line the light up with its magnetic ring.

One button switches between 2900, 4500, 5600 and 6700 K, the other between four brightness levels. From a warm evening tone to cool daylight, the light adapts to the scene.

Brightness is controlled by PWM, so you see practically no flicker in your footage. At 0.3 m the light delivers 450 lx, and with a CRI of 90–94 it renders skin tones faithfully.

The built-in 500 mAh (1.85 Wh) battery lasts about 14 hours at the lowest level and about 75 minutes at full power. It charges via USB-C (5 V / 1 A) in about 1.3 hours; a silicone plug protects the port.

The light measures 6 × 3.25 × 2.6 cm and weighs about 50 g. It takes almost no space on the camera and fits in any pocket, ready for portraits, trips and product shots.

The light resists splashing water from any direction but must not be submerged. Operating and storage temperature is −10 to 40 °C. Four indicators on the side show the battery level. Magnetic mounting on a phone or metal surface is meant for static shots or slow movement; for fast action use the quick release.
