There are several types of reflective sheeting. Engineer grade is the most common and is known as a type 1 film. Super engineer grade is a type 2. High intensity is the brightest glass bead film and is a type 3. The first prismatic film is a type 5. The brightest film is a type 8 and is often called crystal or diamond grade. We have charts on each of the films below. Exact intensities will vary by manufacturer but the charts below are a good guide. Also, please note that the Type 3 High Intensity chart also defines observation and entrance angles.
