Model: GL-R550 Retro 550 LED Bar

Key Features:

Plug-and-Play AC Power:
Simply plug into any standard US outlet (100–240V) and you're ready to go. No batteries to charge, no power interruptions mid-show — just reliable, consistent output all night long.

Professional DMX512 Control with RDM:
Works seamlessly with all major DMX consoles right out of the box. The built-in RDM function lets your console communicate two-way with the fixture — no more walking to the stage to troubleshoot.

4 Channel Modes to Match Any Setup:
Whether you're running a simple 4-channel RGBW wash or a full 44-channel zone-controlled show, the GL-R550 adapts to your rig. Choose from CH04, CH13 (default), CH35, or CH44.

10 Individually Addressable RGB Zones:
Dial in precise color control across 10 separate RGB zones plus 5 white zones for eye-catching, dynamic effects that stand out at any event.

Master/Slave Sync:
Daisy-chain multiple GL-R550 bars with a standard 3-pin DMX cable. Set one as master and every other bar locks in sync instantly — perfect for DJ booths, stages, and uplighting rigs.

Ultra-Smooth 32-Bit Dimming:
Say goodbye to choppy fades. 32-bit linear dimming delivers silky-smooth 0–100% transitions on every channel, every time.

Three Powerful Built-In Effect Engines:
Color dyeing, explosion bursts, and auxiliary light effects are all built in — no laptop or extra software needed.

Benefits:

Whether you're lighting a wedding reception, corporate event, nightclub, or backyard party, the GL-R550 gives you the professional-grade output and control that mobile DJs and event lighting pros demand. Durable metal construction, flexible DMX channel options, and powerful dual-source lighting (COB + 5050 beads) means you can walk into any venue and deliver a stunning show with confidence.

Master/Slave Setup (No Console Needed):

Connect two or more GL-R550 bars with standard 3-pin DMX cables, daisy-chained.
Set one fixture as Master — this unit controls the show.
All other fixtures automatically become Slaves and mirror the master in real time.
Works for gradients, pulses, color jumps, sound-active, and auto-run effects.

⚠️ Important: Only set ONE fixture as master per chain. Multiple masters will cause all fixtures to flash out of sync.
