Millisecond-precise lanyard synchronization via standard DMX512. Connect the GFC005 transmitter to any lighting console and program lanyard color changes, flashing patterns, and brightness cues directly into your show file. No proprietary software. No custom protocol. Just industry-standard DMX.
The same protocol that controls stage lighting, LED walls, and moving heads — now controlling LED lanyards.
DMX512 (Digital Multiplex with 512 channels) is the worldwide standard for controlling entertainment lighting equipment. Every professional lighting console — from grandMA to Hog to Chamsys to Avolites — speaks DMX512 natively. The protocol transmits 512 individual control channels over a single 3-pin or 5-pin XLR cable, with each channel carrying a value from 0 to 255.
The GFC005 transmitter converts DMX data into RF signals that LED lanyards receive and execute. Because the RF transmission reaches all lanyards simultaneously (not sequentially), every unit responds within milliseconds of the DMX command — regardless of whether there are 200 units or 50,000 units in the audience.
There is no Wi-Fi dependency, no network configuration, and no app installation. The lanyards simply listen for the RF signal and display the color, brightness, and mode specified by the DMX channel assignment. This makes DMX control the most reliable and lowest-latency option for live event synchronization.

The hardware that connects your lighting console to every LED lanyard in the venue.
Five steps from unboxing to audience synchronization. No proprietary workflow — designers work in their familiar console environment.
Plug a standard 3-pin DMX cable from your lighting console's DMX output to the GFC005 transmitter input. Apply DC power. The unit auto-detects the DMX signal — no dip switches, no menu navigation. A status LED confirms the DMX connection.
Each lanyard listens to three consecutive DMX channels: Channel 1 controls Red (0-255), Channel 2 controls Green (0-255), Channel 3 controls Blue (0-255). For zone control, assign different channel groups — e.g., channels 1-3 for VIP section, 4-6 for general admission, 7-9 for stage crew.
Program lanyard cues just as you would any DMX fixture. Create color presets, fade effects, strobe sequences, and chase patterns. Because the lanyards respond to standard DMX values, you can use your console's effects engine — bumps, fades, tempo-sync — without additional hardware or software.
Each lanyard is pre-configured at the factory to receive the GFC005 signal. There is no pairing process, no app download, and no Wi-Fi network. Audience members simply wear the lanyard — it is already registered with the transmitter and ready to respond to DMX commands.
Execute your pre-programmed cues during the performance. The lanyards change color in perfect synchronization with the stage lighting, video content, and audio timeline. Because the RF transmission is instantaneous and the GFC005 buffers the last received DMX value, lanyards maintain their color even if the console is temporarily disconnected.
All GFH models can be configured for DMX control. Some models, however, are better suited than others depending on your event goals.
Custom Acrylic + Sublimation
The strongest visual impact of any model. Custom-shaped acrylic badge laser-cut to your logo or design. When paired with DMX control, thousands of branded shapes change color in perfect unison — creating a living brand installation across the entire audience. The combination of unique badge shapes and synchronized lighting draws maximum attention from attendees, cameras, and social media.
Nylon + ABS
The only model with LEDs on both the strap (8 on strap + 2 on badge) and the badge. Because the strap itself lights up, the wearer becomes part of the light show — not just the badge. This makes GFH-001 the preferred choice for large-scale events where the audience needs to be visually unified across a stadium or arena. Reliable 433MHz RF with 250m range.
Round Medal
DMX control is available for GFH-003, but its strongest application is as a standalone medal with push-button control. The 10-LED circular array and interchangeable fabric sleeve make it ideal for VIP passes, awards, and commemorative souvenirs. For an elevated experience, consider a dedicated branded mobile APP (GFC008) — attendees can control their medal's color and flashing patterns from their phone, adding a social and interactive dimension to the event.
GFLAI has been manufacturing LED products in Shenzhen since 2005. Every component — from the LED module and battery compartment to the GFC005 transmitter — is designed, assembled, and tested in our facility. There is no subcontracting, no third-party assembly, and no quality gap between your order and the product shipped.
This vertical integration is what allows us to offer DMX-controlled LED lanyards at factory-direct pricing. When you order from GFLAI, you are buying from the source — not from a distributor marking up a white-label product.
FCC, CE, RoHS, and KC certified. DDP shipping to the US, UK, EU, Canada, and APAC markets.
Real-world deployments where DMX control made the difference.
30,000 GFH-001 lanyards across 12 tour dates. GFC005 connected to grandMA3 console. Lanyard colors cued to each song's lighting look — white for ballads, RGB cycling for anthems. During the encore, a slow red fade swept across the entire audience, synchronized with the LED screen fade-out.
"The production team programmed lanyard cues alongside moving heads and LED walls — same console, same timeline, no extra hardware."
5,000 GFH-005 custom acrylic badges with artist logos. DMX control allowed the lighting director to match lanyard colors to each award category — blue for music, gold for film, green for television. Because the GFC005 provides millisecond sync, camera cuts showed consistent audience colors without frame mismatch.
"Every camera angle showed the same audience color at the same moment — critical for broadcast consistency."
2,000 GFH-004 acrylic lanyards for a global brand launch. Three DMX zones separated the main hall into brand color sections. During the CEO's keynote, all lanyards transitioned from the brand's signature blue to the new product color — creating a visual narrative that the audience experienced collectively.
"The zone control meant different audience sections could display different colors simultaneously."
