Whether you're recording YouTube videos, producing TikTok content, photographing portraits, filming interviews, or creating mobile video productions, the NEEWER Basic GC21B offers a versatile combination of portability, adjustable lighting, and convenient mounting options.

Innovative Inflatable LED Lighting Design

The NEEWER Basic GC21B features an innovative inflatable LED light design that provides a different approach to portable photography and video lighting.

Instead of relying on a rigid conventional light-stick body, the GC21B uses an inflatable structure designed for compact storage and convenient transportation.

This makes it useful for creators who need to carry lighting equipment between locations.

The inflatable body is constructed from TPU and silicone, providing a flexible protective structure around the internal lighting components.

The light should be inflated and handled according to the manufacturer's instructions to avoid damaging the material or internal components.

90cm Inflated Length

When inflated, the NEEWER GC21B reaches approximately 90cm (35 inches) in length.

This elongated form factor provides a practical lighting shape for portraits, interviews, product photography, and video production.

The light can be positioned vertically or horizontally using suitable mounting arrangements.

Its inflated length makes it useful for creative lighting setups where a longer light source is preferred.

Compact Dimensions Before Inflation

Before inflation, the NEEWER GC21B measures approximately 22 × 12 × 2.5cm.

These compact dimensions make it convenient to store in suitable camera bags, backpacks, and equipment cases.

The included storage bag provides an additional carrying solution.

The compact uninflated design is particularly useful for travel photographers, vloggers, and mobile content creators.

Ultra-Lightweight 260g Construction

The NEEWER GC21B has a stated weight of approximately 260g (9oz).

This lightweight construction makes it easy to transport between shooting locations.

It is particularly useful for creators who want to minimize the weight of their photography and video equipment.

The supplied specifications do not clarify whether the stated weight includes the magnetic stand, charging cable, and storage bag.

320 LEDs with 21W Maximum Power

The NEEWER GC21B features 320 LEDs with a maximum stated power output of 21W.

The LED array is designed to provide adjustable illumination for photography and video recording.

This makes the GC21B useful for portrait lighting, interview setups, product photography, podcasts, and social media content creation.

The exact distribution of LEDs between warm and cool color channels has not been specified.

Maximum Illumination of 1300 Lux at 0.5m

The NEEWER GC21B delivers a stated maximum illumination of approximately 1300 lux at 0.5m.

This output provides useful lighting for close-range photography and video applications.

The light can be used as a fill light, creative accent light, or supplemental light source depending on the shooting environment.

Actual illumination depends on distance, color temperature, brightness settings, and positioning.

The manufacturer-supplied lux measurement should not be assumed to apply equally to every color temperature setting.

Adjustable 2700K–6500K Bi-Color Temperature

The NEEWER GC21B supports a 2700K–6500K adjustable color temperature range.

This allows creators to switch between warm and cool white lighting.

Warmer settings can be useful for indoor scenes and atmospheric lighting, while cooler settings can complement daylight-style environments.

The adjustable color temperature provides flexibility for interviews, podcasts, product photography, portraits, and video recording.

It also helps creators adapt lighting to different environments and existing light sources.

0–100% Brightness Adjustment

The NEEWER GC21B supports 0–100% brightness adjustment.

This allows users to control the light intensity according to the subject and shooting environment.

Lower brightness settings can be useful for subtle fill lighting, while higher settings can provide stronger illumination when required.

The adjustable brightness makes the light suitable for a variety of photography and video applications.

CRI 95 Color Rendering

The NEEWER GC21B features a stated CRI rating of 95.

CRI measures how accurately a light source renders colors compared with a reference illuminant.

A high CRI rating is useful for portrait photography, product photography, interviews, and video recording.

This helps creators capture more natural-looking colors when the camera and lighting setup are properly configured.

Final color reproduction also depends on camera white balance, exposure, and post-production.

Built-In 7.4V 2500mAh Battery

The NEEWER GC21B includes a rechargeable 7.4V 2500mAh battery, equivalent to approximately 18.5Wh.

The built-in battery allows the light to operate without a continuous external power connection.

This makes it suitable for travel photography, outdoor filming, mobile content production, and location-based recording.

The manufacturer states up to approximately 50 minutes of runtime at 100% brightness.

Actual runtime can vary depending on brightness, operating conditions, temperature, and battery condition.

USB Type-C Charging

The GC21B supports charging through a USB Type-C interface.

The specified charging input is 5V/3A.

The manufacturer states an approximate full charging time of 120 minutes when using a suitable power source.

A USB Type-C charging cable is included in the package.

A wall charger is not listed among the supplied accessories.

12 Built-In Lighting Effects

The NEEWER GC21B includes 12 built-in lighting effects designed for creative video production.

The supplied examples include:

• Paparazzi

• Explosion

• Welding

• Defective Bulb

• CCT Flicker

• CCT Pulse

These effects allow creators to simulate different lighting environments during video recording.

They can be useful for cinematic scenes, creative social media videos, music videos, and experimental content production.

The complete list of all 12 effects has not been provided in the supplied specifications.

0.98-Inch Color Display

The NEEWER GC21B features a 0.98-inch color display.

The display provides information about brightness, color temperature, battery level, and selected lighting modes.

This makes it convenient to review and adjust settings during photography and video recording.

The integrated display reduces the need to rely on external equipment for basic lighting adjustments.

Built-In Magnetic Mounting

The NEEWER GC21B features an integrated magnetic mounting module.

This allows the light to attach to suitable ferromagnetic metal surfaces.

Magnetic mounting provides flexibility when setting up lighting in compatible environments.

It can be useful for temporary lighting positions, studio setups, and creative background illumination.

Always verify that the magnetic connection is secure before releasing the light.

Magnetic Stand with 1/4-Inch Mount

The package includes a magnetic stand featuring a standard 1/4-inch mounting thread.

This allows the light to be attached to compatible photography and video support accessories.

Suitable equipment may include tripods, light stands, and mounting arms with the appropriate interface.

This provides additional positioning options when direct magnetic mounting is not suitable.

The exact weight capacity of the magnetic stand has not been separately specified.

Hanging Straps for Flexible Positioning

The GC21B includes integrated hanging straps designed for vertical or horizontal suspension.

This provides an alternative mounting option for compatible shooting environments.

The straps can be useful when positioning the light in areas where a conventional stand is impractical.

Always confirm that the suspension point is secure and suitable for the light's weight.

Ideal for Mobile Content Creation

The NEEWER GC21B is particularly suitable for creators who frequently work outside a permanent studio.

Its compact uninflated dimensions, lightweight construction, rechargeable battery, and multiple mounting options make it practical for mobile video production.

It can be used for interviews, travel vlogs, podcasts, social media videos, and other creative projects.

The inflatable design also makes it convenient to store between shooting sessions.
