The light intensity was 16,000-18,000 lux at 50 cm from the light source. To obtain reproducible light intensity, the irradiation power at the fiber outlet was measured using a digital lux tester. Light from the television was 10-20 lux. To reduce blackfly activity, dim (less than 50 lux) torchlight was directed up from beneath the chamber as the only illumination. The floodlighting system, with a density of 2000 lux, has been inaugurated in 2008. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license.
