Lembaran manik kaca retroreflective
Pita manik kaca menggunakan sfera kaca mikroskopik untuk membengkokkan dan memantulkan cahaya kembali ke sumber cahaya. Kerana ketidaksempurnaan dan permukaan melengkung dalam manik kaca,cadarmade with beads are less reflective than tapes made with prisms. Glass bead cadar are about 30 percent efficient. This is a disadvantage. However, there are three advantages that glass bead cadar has over most prismatic cadar. First, glass bead reflective cadar are much more affordable. This is because they are simpler to manufacture. Second, most glass bead sheeting are CAD cuttable meaning that you can cut letters, number and designs out of the tape and create reflective signs or graphics. Third, glass bead cadarreflect light back at wider angles. In other words, glass bead cadar are sort of like flood lamps whereas prismatic sheeting are more light spot lights.

Kepingan prismatik mikro
Prismatic is more efficient and returns about 80 percent of the light sent to it. Therefore it is brighter than glass bead tapes. Prismatic tape reflects light via man made prisms. Since the mirrors are flat and not curved they are more efficient. The light sent from the tape is more focused and can therefore travel farther still be seen.
