A external light control device for equatorially located building utilizes tilting external light shelves that are capable of tilting backward (toward the building) from a vertical orientation to reflect low am (or late pm) sun away from occupants, but are deployed at a tilt away from the building exterior to capture more sun closer to noon time. The structure preferably integrate IR rejecting coating for incident light which is re-directed by TIR surface disposed normal to the thin film layers in a multi-layer IR reflective coating. The panel may be monolithic or comprise tilting louvers, which can be metallic, dielectric, or TIR reflectors. The louvers preferably also tilt in response to the determined sun position with the panel to optimize light utilization.
