About Picocandelas
The picocandela (pcd) equals 10⁻¹² cd. A theoretical subunit used only in precision photometric standard traceability and single-photon detector characterisation. The faintest LED indicator in standby mode (~10 µcd) is one million times brighter. Appears in calibration chain documentation. 1 pcd = 10⁻¹² cd.
About Megacandelas
The megacandela (Mcd) equals 10⁶ cd. The range for powerful searchlights and lighthouse optics: a large maritime lighthouse lens emits 1-10 Mcd; military anti-aircraft searchlights of WWII reached 1-2 Mcd; modern LED lighthouse arrays 2-5 Mcd. 1 Mcd = 10⁶ cd.
