KOBAIBAN A3 Magnetic Light Box 3 Modes 🖼

This A3 magnetic light box offers a bright, portable tracing surface for crafters and artists who need an even, reliable workspace for tracing, diamond painting, weeding vinyl, and sketching. With multiple color modes and stepless dimming, it helps reduce glare and eye strain while allowing precise control over illumination during detailed tasks.

Key Points

The panel supports three color temperatures: white, warm white, and warm yellow, letting you pick the tone that best suits paper thickness and ambient light. Long-press the physical button for stepless dimming up to a maximum of 5400 lux according to the manufacturer, or short-press to step through six preset brightness levels. Physical buttons are included to avoid accidental touches while working on intricate pieces. The surface is scratch-resistant, though sharp tools should be avoided to preserve the finish. A built-in auto-memory function restores the last used setting to save time when you resume a project.

Benefits

The internal 4000 mAh battery provides portability with about 4+ hours runtime at maximum brightness and approximately 8+ hours at medium brightness, making it easy to work without being tethered to a wall outlet. USB-C fast charging restores power in around 3.5 hours, and the stable USB-C port is more robust than older micro-USB connectors. The four supplied magnets and magnetic holder keep papers, stencils, or X-ray films in place even when the board is slightly tilted. Anti-slip silicone feet add steadiness on desks or laps during prolonged sessions.

Usage Recommendations

For fine tracing or diamond art, start with the warm white mode to reduce contrast harshness, then adjust brightness slowly with a long press until edges are clearly visible without glare. Use the short-press preset levels when you need quick changes between tasks. The padded carrying bag lined with soft anti-scratch fabric helps protect the panel during transport and makes it straightforward to carry to classes, meetups, or crafting events. Consider that the illuminated area fits A3-sized sheets and most diamond painting kits, while the ultra-slim profile allows easy storage in portfolios or backpacks.

Note that while flicker-free technology is included to help lower eye fatigue, extended sessions may still require occasional breaks for comfort. The product comes with a simple illustrated guide to help set up and operate the light board.
