About Stilbs
The stilb (sb) equals 1 cd/cm² = 10⁴ cd/m². The CGS luminance unit. A candle flame has luminance ~0.5-0.6 sb; a frosted incandescent bulb ~10 sb; a xenon short-arc lamp up to 170 000 sb. Named from the Greek στίλβω (to glitter). Found in pre-1970 photometry texts. 1 sb = 10⁴ cd/m².
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.
