ULANZI 100W RGB Portable LED Video Light - High-Power COB Handheld

Our review of the ULANZI 100W RGB Portable LED Video Light finds it a strong choice for creators who need a compact, powerful continuous light that can run untethered. The biggest reason to buy is its combination of a high-output 100W COB lamp and a built-in 111Wh battery, which delivers real wireless flexibility without sacrificing brightness or color control. In testing, the unit proved easy to mount, simple to adjust with the stepless knob and LCD, and versatile enough for run-and-gun shooting, small studio setups, and on-location interviews.

Key Features

• 100W High-Power Brightness: Powerful COB lamp beads produce strong, even illumination that fills small to medium scenes without harsh hotspots.
• Wireless Operation: The integrated 111Wh battery lets users work untethered for up to several hours at low settings, ideal for mobile shoots.
• Stepless Dimming: A smooth adjustment knob allows precise control of intensity, making subtle exposure changes quick and repeatable.
• Adjustable Color Temperature: Tunable 2700K to 6500K color range covers warm to daylight tones, useful for matching ambient light or creative looks.
• Mini Bowens & LCD Display: The Mini Bowens compatibility expands modifier options, while the LCD gives real-time confirmation of settings.
• Compact, Portable Design: Metal construction and a lightweight form mean the light is easy to carry and mount on stands or handheld for spot lighting.

Who It's For

This light is best for independent videographers, content creators, and small production teams who need a high-output portable fixture that can run on battery power. Its combination of COB output, stepless dimming and a broad color temperature range makes it well suited to interview work, on-location product videos, and ambient fill lighting.

Those who should look elsewhere include large studio productions that require banked lighting systems or users who need integrated DMX control and advanced wireless ecosystem features. If you need extremely long continuous full-power runtimes without swapping batteries, a mains-only fixture would be a better fit.
