Ulanzi LM21 Magnetic Fill Light for MagSafe Phones

The Ulanzi LM21 Magnetic Fill Light snaps onto your phone in one move, giving you soft, flattering light for selfies, vlogs and live streams. It works directly with MagSafe phones, and the included magnetic adapter ring lets non-magnetic phones use it too.

This pocket-sized ulanzi fill light weighs only about 66g. It folds down to 7.1 × 6 × 2cm, so it fits in a pocket, bag or camera kit.

Tap to switch between warm, neutral and cool white light, then turn the dial to set the brightness you want. With a CRI of 95 or higher, skin tones and products look natural on camera.

Key Features

• Magnetic Snap Attachment: The light attaches instantly to MagSafe phones, or to non-magnetic phones with the included adapter ring. You can set up a shot in seconds without clamps or tripods.
• Pocket-Sized Foldable Design: It measures 7.1 × 6 × 2cm folded and 17.7 × 6 × 2cm extended, and weighs about 66g. It is easy to carry everywhere and light enough that it will not weigh down your phone.
• Touch Switch and Stepless Dial: Tap the touch-sensitive switch to change color temperature and turn the dial to adjust brightness smoothly. You can fine-tune the light without opening any menus.
• 180° Flip Design: The light extends by 4.5cm and flips beyond 180°, so it can light you from the front or the back. This gives you more angles for selfies, product shots and creative setups.
• Three Color Temperatures: Choose warm 2500K, neutral 5600K or cool white 8000K to match your scene. A CRI of 95 or higher keeps colors accurate and natural.
• Fold and Extend for Multi-Angle Lighting: Adjust the light direction freely to suit your shooting scenario. You can get softer, more even fill light without moving your phone.
• Type-C Charging: The built-in 500mAh battery charges through a Type-C port. Runtime is about 1.2 hours at maximum brightness and about 8 hours at minimum brightness. You can also connect a power bank to keep shooting while it charges.
• Built-In Desktop Stand: Use the LM21 as a quick stand for hands-free viewing on your desk. One accessory covers both lighting and phone support.
• Magnetic Back for Extra Setups: The back side attaches to ferrous surfaces, so you can mount the light on metal objects for creative setups.
• CE, RoHS and FCC Certified: The light meets international safety and quality standards, which supports safe everyday use.
