ULANZI LED Video Light Waterproof IP68 Mini Cube - Compact Fill Light

In this review the ULANZI LED Video Light Waterproof IP68 Mini Cube is assessed as a compact, purpose-driven lighting kit for creators who need portable, reliable illumination. The biggest reason to buy is its combination of true waterproofing to 32ft and a daylight balanced 5500K output with 95+ CRI, which makes it useful for both underwater and on-camera work. The review finds the unit best for run-and-gun shooters, vloggers, and underwater hobbyists who value small size and a full accessory kit.

Key Features

• Waterproof IP68: The enclosed lamp body with a magnetic charging interface provides full waterproof protection to 32ft, letting users shoot in wet conditions without exposing the charging port.
• Daylight Balanced 5500K: Accurate color temperature and 95+ CRI deliver natural skin tones and reliable color for photos and video.
• Dimmable Output: Four brightness levels from 25% to 100% make it easy to adjust light intensity for close-up micro photography or wider fill light needs.
• Portable Mini Cube: At about 41mm x 41mm x 38mm and 70g, the cube fits into most gear bags and is convenient for on-camera or action rig use.
• Accessories Included: The kit includes gels, diffuser, honeycomb, barn door, snoot, storage bag and mounting hardware to cover a wide range of creative setups.

Who It's For

The ULANZI Mini Cube is ideal for vloggers, travel shooters, and underwater hobbyists who need a small but capable light that can attach to cameras, rigs, or metal surfaces. Its IP68 rating and compact size make it especially useful for action camera users and those who shoot in wet or outdoor environments.

It is less appropriate for extended studio shoots or situations requiring many hours of continuous high-output lighting without access to charging, since the built-in 800mAh battery runs about 1 hour at full power. Users needing very high output or long runtimes should consider larger, dedicated fixtures.

Pros & Cons

Pros

• Very portable cube design with useful mounting options including a built-in magnet and 1/4" 20 screw hole.
• Good color fidelity from the 5500K, 95+ CRI LEDs for natural-looking photos and video.
• Comprehensive accessory kit adds versatility out of the box and increases creative options.
• Full waterproof IP68 construction protects the unit and charging port for underwater use.

Cons

• Battery life is limited at full power (around 1 hour) so users may need to recharge between long sessions.
• Some customers report mixed functionality experiences, so occasional quality control issues can occur.
