High-Power 40W COB LED with Full 360° HSI Color Tuning
You can now create bold, professional studio visuals without setting up heavy, bulky lighting fixtures. The Ulanzi 40W RGB LED Light utilizes advanced Chip-on-Board (COB) technology to deliver dense, uniform beam output across the full 360-degree HSI color spectrum. Because you can control hue, saturation, and brightness with high precision, dialing in dramatic hair lights, dynamic background accents, or creative key lighting for YouTube videos is seamless. If you need an ultra-compact pocket-sized light for mobile vlogging instead, explore our Ulanzi LM01 RGB Light.
Tunable Bi-Color CCT with High CRI 95+ Color Fidelity
Do not compromise on natural skin tone accuracy when switching from atmospheric RGB lighting to clean white light. This versatile COB studio light features broad color temperature tuning for every environment:
Broad 2500K to 6500K Range: First, transition smoothly from warm tungsten lighting to cool, crisp daylight.
Pro-Grade CRI 95+ Rating: Next, high color rendering guarantees true-to-life skin tones and accurate product presentation.
Specialized FX Lighting Scenes: Finally, trigger built-in creative lighting effects like Lightning, Candlelight, TV, and Strobe to elevate cinematic video concepts.
Included DC Power Adapter & Dual Power Versatility
You will no longer experience sudden power cutoffs during critical live streams or long interview shoots. This bundle comes complete with a high-capacity DC power adapter for uninterrupted mains power in studio setups. Furthermore, the light supports Type-C fast charging protocols, letting you power the unit using high-wattage power banks or V-mount batteries when shooting on location. For reliable studio positioning, attach this COB light directly to our sturdy Ulanzi Heavy Duty Video Tripod.
Active Cooling Quiet Fan & Standard Mount Compatibility
Do not let overheating or loud equipment ruin your audio recording. The Ulanzi 40W RGB LED Light features an intelligent silent cooling fan that dissipates heat efficiently while maintaining ultra-low noise levels suitable for sensitive directional microphones. In addition, its universal 1/4″-20 mounting socket and mini reflector bayonet let you attach softboxes, diffusion domes, and light stands quickly during fast-paced production schedules.
