Two light box types dominate storefronts: the fabric/frame box (often called a kapok box) and the vacuum-formed acrylic box. Most buyers cannot say which one they need — but three questions settle it.
Question 1: Will you change the graphic often?
Fabric boxes stretch a printed textile or soft film over a frame, so artwork can be swapped in minutes without touching the structure. Vacuum-formed boxes use a moulded acrylic face — changing the graphic means remaking the face. Frequent promotions, seasonal menus and rotating campaigns point to fabric.
Question 2: Is it outdoors year-round?
Vacuum-formed acrylic is a rigid 3D shell: it resists rain, wind and impact, and holds its shape for years. Fabric faces are tensioned and can sag, crease or discolour with prolonged UV exposure. For outdoor storefronts and convenience-store chains, choose vacuum-formed.
Question 3: Flat and slim, or three-dimensional?
Fabric boxes are usually slim and completely flat, giving a clean modern panel. Vacuum-formed boxes are three-dimensional — up to 30–40 cm of relief — which reads better from across a street and can carry a product shape or logo form.
Practical notes
- Both types need even backlighting; ask for the LED pitch and driver power, not just "with LEDs".
- Check the waterproofing of the power enclosure and cable joints — this is the most common outdoor failure point.
- Double-sided vacuum-formed boxes are available for projecting signs read from both directions.
