Is emergency illumination between 15 and 50 Lux?

1 lux is the requirement of EN 1838 for escape routes 0.5 lux for open area's. Areas of high physical risk, or the control rooms of dangerous plant and production lines, need emergency lighting to enable them to be shut down safely. BS5266 Part 1: 1999 defines that emergency lighting should provide 10% of the normal lighting level at the hazard, with a minimum of 15 Lux.
