About Meganits
The meganit (Mcd/m²) equals 10⁶ cd/m². The scale for extreme light sources: outdoor LED video walls at peak brightness reach 3-10 Mcd/m²; laser exit apertures are typically 10-10 000 Mcd/m²; the solar disc at zenith has luminance ≈1 600 Mcd/m² (1.6×10⁹ cd/m²). Used in laser safety and high-power illumination. 1 Mcd/m² = 10⁶ cd/m².
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 An incandescent lamp globe at 3 200 K has luminance ~1 L; a clear sky is ~0.94 L. Superseded by cd/m² in SI photometry. 1 L = 10⁴/π cd/m².
