About Candelas
The candela (cd) is the SI base unit of luminous intensity. A standard wax candle emits ~1 cd; a 60 W incandescent bulb ~60 cd (assuming Lambertian emission); a 1 W white power LED ~100 cd peak in a 5° beam. Defined since 2019 by fixing K_cd = 683 lm/W at 540 THz. 1 cd = 1 lm/sr.
About Nanocandelas
The nanocandela (ncd) equals 10⁻⁹ cd. The scale of extremely faint bioluminescence: a single luciferin-luciferase reaction emits around 1-10 ncd; dark-adapted firefly flashes peak at a few hundred ncd. Also the range for cooled avalanche-photodiode sensitivity characterisation. 1 ncd = 10⁻⁹ cd.
