PE plastic and acrylic LED lightboxes look similar in product photos but there is a difference between PE plastic and acrylic LED lightbox in commercial use. Here is the honest comparison.
PE plastic lightboxes are built from a single continuous mould with no bonded joints. Acrylic lightboxes bond a separate panel into a metal frame, and that bond is where the problems start.
As temperature changes between venues, the acrylic and metal expand at different rates. Over months, the bond weakens, the panel shifts, and the illumination becomes uneven near the edges. By month four or five, many acrylic displays look noticeably tired.
PE plastic absorbs impact rather than cracking. There are no joints to fail because there is no interface between separate components. The display looks identical in year three to day one.
This is why Boardsy backs every Standing Light Box with a lifetime build guarantee.
