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 An incandescent lamp globe at 3 200 K has luminance ~1 L; a clear sky is ~0.94 L. Superseded by cd/m² in SI photometry. 1 L = 10⁴/π cd/m².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 Millilamberts

The millilambert (mL) equals 10/π cd/m² ≈ 3.183 cd/m². Historically used in the United States to specify projection screen luminance and oscilloscope phosphor brightness. A projection screen with luminance 1 mL ≈ 3.18 cd/m². Largely superseded by cd/m² and foot-lamberts in modern display standards. 1 mL = 10/π cd/m².
