The Cree LR4 series is designed for new construction only and requires the use of the Cree H4 architectural housing and your choice of finish in the LT4 trims. Two models are available, the LR4-15 which is a moderate recess unit with a 15 degree shield angle and the LR4-30, a deep recess unit with a 30 degree shield angle. Please note that we offer the LR4 as the light engine only or in a package with the H4 housing and an anodized trim piece for easier ordering.
