Contact us with your light box dimensions and planned bar quantity for a recommended driver configuration. Three Lengths for Different Light Box Designs Choose from 212mm, 319mm and 480mm bars to match different light box dimensions and installation layouts. The three lengths share the same DC24V platform and plug-in connection concept, making it easier for production teams to standardize their lighting system across different display sizes. Modular Linkable Design — Scale Without Complexity Each LED bar features plug-and-connect terminals, allowing multiple units to be linked together without complex wiring. Simply connect bars in series and power the run from a single DC24V driver. No soldering, no wire management headaches — just a clean, professional installation every time. High Output Illumination — Up to 2000lm per Bar From 900lm (9W / 212mm) to 1400lm (14W / 319mm) to 2000lm (20W / 480mm), choose the output level that matches your light box depth and diffusion requirements. The 20°×60° asymmetric optical lens directs light toward the display surface and helps improve light distribution inside the light box. Final uniformity depends on frame depth, diffuser material and LED spacing. 4 CCT Options — Match Any Brand Environment Available in four color temperature ranges — 2800–3200K, 3700–4300K (neutral), 4700–5300K, and 6000–7200K (daylight) — so you can match the exact lighting mood required for retail, exhibition, or advertising applications. Every bar is factory-binned to the same CCT, ensuring consistent color across all panels in your display. Faster Installation — Reduce Labor Time on Every Project The modular connection system significantly reduces installation time compared with individually wired LED modules. Snap connections lock securely and allow single-bar replacement without rewiring the entire run — critical for trade show and retail environments where downtime is not an option. Aluminum Housing — Long Lifespan, Reliable Performance The all-aluminum body dissipates heat efficiently, protecting LED performance over a rated 50,000-hour lifespan. Consistent brightness season after season — reducing replacement costs and maintenance overhead. Linkable Connector System — Plug-In Daisy Chain Polarity-keyed — no reverse-connection risk Secure latch lock — stays connected even with cable movement Daisy-chain up to 5 bars per driver run No soldering, no wire stripping — plug and go Compatible with standard DC24V commercial LED drivers Need a custom connector configuration for OEM or bulk orders?
