Abstract
A lamp optic (100) for a lamp includes a proximal end (104), a distal end (106) and a longitudinal axis (L). The proximal end (104) has a proximal inner side wall (112) linearly extending toward the distal end (106) and intersecting a proximal flat portion (114). The distal end (106) has a distal inner side wall (120) linearly extending toward the proximal end (104) and intersecting a distal flat portion (122). The distal flat portion length (LD) is at least 25 percent of the proximal flat portion length (LP). A lateral side (108) extends from the proximal end (104) to the distal end (106). The lateral side (108) has a first skirt region (124) and a second skirt region (126). The first skirt region (124) and the second skirt region (126) extend linearly and successively from the proximal end (104) to the distal end (106).
