IP-B820 vs IP-B1620: What Is the Difference?

Although both fixtures share the same design concept and many control features, they serve different installation requirements.

The IP-B820 is better suited to compact layouts and installations requiring more individual positioning flexibility.

The IP-B1620 is useful when designers need longer linear lighting sections and fewer physical breaks across a larger stage or architectural surface.

They can also be used together when a design requires different bar lengths within the same visual system.

RGBA 4-in-1 LED Color System

Both models use an RGBA 4-in-1 LED system.

RGBA combines:

• Red
• Green
• Blue
• Amber

inside the lighting system.

The addition of amber expands the available color palette and is particularly useful when creating warmer colors for applications such as:

• Weddings
• Hotel events

• Stage backgrounds
• Decorative installations

At the same time, RGB combinations allow the fixtures to create saturated colors for concerts, nightclubs, DJ stages and entertainment productions.

2000K–10000K Adjustable Color Temperature

A major feature of the IP-B820 and IP-B1620 is the wide:

2000K–10000K adjustable color temperature range.

This allows the same fixture to adapt to different environments.

For example:

Warm color temperatures can be used for:

• Weddings
• Hospitality events
• Banquet halls
• Decorative environments

More neutral or cooler settings can be useful for:

• Exhibitions
• Corporate stages
• Product presentations
• Modern architectural lighting

This flexibility helps reduce the need to use completely different fixtures when an event requires both decorative color effects and different white-light appearances.

20° Beam Angle with Optional 10° and 40° Optics

The standard beam angle is:

20°

while:

10° and 40° options

are available.

This gives lighting designers more flexibility when planning different installation distances and coverage requirements.

10° Beam

Suitable when a narrower and more concentrated beam is preferred.

20° Beam

A balanced option for general stage, wall wash and event applications.

40° Beam

Useful when wider surface coverage is required.

Selecting the correct beam angle should depend on installation distance, target area and desired lighting effect.

Splicing Design for Creative Stage Structures

One of the defining features of this series is the ability to splice multiple bar lights together.

Instead of treating every fixture only as an independent uplight, designers can use multiple units to create larger visual structures.

Possible arrangements include:

• Straight lines
• Long continuous bars
• Corners
• Rectangular frames
• Geometric patterns
• Stage borders
• DJ booth structures
• Exhibition booth outlines
• Architectural linear designs

This makes the IP-B820 and IP-B1620 suitable not only for illumination but also for visual stage design.

Combining shorter and longer fixtures can provide additional flexibility when building custom structures.

Battery-Powered Lighting for Faster Event Installation

Both products use rechargeable 18650 lithium battery systems.

The IP-B820 has a:

13,200mAh battery

21,000mAh.

Battery operation is especially useful for projects where power cables would be difficult, unattractive or time-consuming to install.

Typical examples include:

• Wedding venues
• Hotel ballrooms
• Temporary events
• Exhibition booths
• Outdoor events
• Building entrances
• VIP events
• Corporate functions

Battery-powered operation can also help keep event spaces cleaner by reducing visible cable runs in certain installations.

Selectable Runtime Modes

The fixtures provide selectable time modes including:

Max / 3 / 4 / 5 / 6 / 7 / 8-hour modes

This allows users to select an operating mode according to the required event duration.

For event companies, this is useful because different projects may require very different runtime priorities.

A shorter event may prioritize stronger output, while a longer event may require extended battery operation.

Multiple PWM Frequencies for Professional Applications

Both models provide selectable PWM frequencies:

• 800Hz
• 1000Hz
• 2000Hz
• 4000Hz
• 12000Hz

Adjustable PWM provides greater flexibility when the lights are used in environments involving cameras or different control requirements.

For productions involving video recording, broadcast cameras, livestreaming or photography, the appropriate PWM configuration can be selected according to the camera and production setup.

Wireless Control Options

The IP-B820 and IP-B1620 support multiple control methods:

• RDM
• 2.4G
• WDMX
• IR
• APP

This makes the fixtures suitable for both professional control environments and fast temporary installations.

Wireless control is especially useful when fixtures are installed:

• Across large wedding venues
• Around exhibition booths
• Along building walls
• In locations where signal cables are inconvenient
• Across temporary event structures

• 

WDMX G3, G4 and G4S Compatibility

Both models support wireless WDMX “G” compatibility with:

G3 / G4 / G4S

This provides additional flexibility for professional event companies already using compatible wireless lighting control systems.

For rental companies and production teams, wireless DMX can significantly simplify temporary layouts where running long signal cables would otherwise take additional installation time.

RDM Support for Professional Lighting Systems

RDM support helps integrate the fixtures into professional lighting control workflows.

For technicians working with larger event systems, RDM capability can simplify fixture configuration and system management compared with installations that rely entirely on manual access to every fixture.

This is particularly valuable when many IP-B820 or IP-B1620 fixtures are distributed across a venue.
