IES (Illuminating Engineering Society) profiles help you achieve a realistic light emission pattern, giving your art an extra dose of realism. The profile you choose will be visible both in real time 3D view and in Photo Tuning. IES profile selection is available for inner lights (point lights, spot lights) but not for external lights (portal lights).
