SLP's extruded Prismatic Pattern 19 lens offers the light control of an injection molded lens at a fraction of the cost. The 3/16" (4.7mm) square based male prisms suppress luminance at critical angles and delivers 92% of the light output to the 0-60 degree zone. Prismatic Pattern 19 is one of the best alternatives when brightness control is a consideration but parabolic louvers are not required.
