LED Bi-Color Inflatable Air Tube Light Neewer GC21B 21W 2500mAh

The Neewer GC21B is a portable inflatable LED bi-color tube light offering continuous, soft illumination for photography and video. With 21W power and an integrated 2500mAh rechargeable battery, this cordless air-filled lamp delivers adjustable color temperature across bi-color range and diffuse output suitable for close-up fill, interviews, and ambient event lighting. The lightweight, inflatable design deflates for compact storage and inflates quickly on location, combining easy transport with usable battery-powered light where mains power is not available.

Advantages

The LED bi-color tube light provides uniform, soft illumination with adjustable color temperature, reducing harsh shadows and the need for additional diffusion. Built-in battery operation enables cordless use for on-location shoots and outdoor events. The inflatable construction minimizes storage volume and simplifies packing for travel. Integrated controls offer direct adjustment of intensity and color balance, and the lamp’s 21W output balances brightness and battery runtime for many continuous-light scenarios.

How to use
