About Megalux
The megalux (Mlx) equals 10⁶ lx. Reached only by extreme short-range sources: a short-arc xenon lamp at 5 cm produces ~1-10 Mlx; pulsed photographic strobes at close range several Mlx. The full solar disc on Earth's surface gives ~100 klx - far below 1 Mlx. 1 Mlx = 10⁶ lx.
About Lumens per square inch
The lumen per square inch (lm/in²) equals 1/0.00064516 lx ≈ 1 550 lx. Used in US optics and LED backlight datasheets when specifying output over small aperture areas. Rare in general lighting but found in US optical engineering catalogs and LCD backlight specifications. 1 lm/in² = 1/0.00064516 lx.
