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 An incandescent lamp globe at 3 200 K has luminance ~1 L; a clear sky is ~0.94 L. Superseded by cd/m² in SI photometry. 1 L = 10⁴/π cd/m².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 Microcandelas per square metre
The microcandela per square metre (µcd/m²) equals 10⁻⁶ cd/m². Used in precision dark-sky photometry and in measuring the luminance of unlit passive surfaces. OLED deep-black levels are typically 0.0001-0.01 cd/m², about 100-10 000 times larger than this scale. 1 µcd/m² = 10⁻⁶ cd/m².
