S4U L1 Monitor Light Bar

Light your desk, not your screen. The S4U L1 Monitor Light Bar mounts on top of your display and throws a focused beam onto your keyboard and workspace while keeping your monitor free of reflections.

The aluminum light bar uses 60 high‑quality LEDs with adjustable color temperature from warm 2900K to cool 6000K, so you can switch from relaxed browsing to focused work lighting. Brightness is fully dimmable, and the optional wireless remote lets you make adjustments without reaching over your monitor.

Powered by a simple 5V USB‑C connection, the L1 fits naturally into modern setups for gaming, coding, and office work.
