About Lamberts
The lambert (L) equals 10⁴/π cd/m² ≈ 3 183 cd/m², the luminance of a perfect diffuse surface emitting 1 lumen per square centimetre. The CGS practical luminance unit. An incandescent lamp globe at 3 200 K has luminance ~1 L; a clear sky is ~0.94 L. Superseded by cd/m² in SI photometry. 1 L = 10⁴/π cd/m².
About Picocandelas per square metre
The picocandela per square metre (pcd/m²) equals 10⁻¹² cd/m². A theoretical subunit for precision photometric standards and astrophysical brightness modelling. Even the darkest measurable surfaces in calibrated laboratories have luminance many orders of magnitude above this scale. Used only in radiometric standard traceability chains. 1 pcd/m² = 10⁻¹² cd/m².
