Lux: The central illuminance should be between 160,000 and 40,000 lux. Light field diameter: The D50 diameter should be at least 50% of D10. Colour rendition: For the purpose of distinguishing true tissue colour in a cavity, the colour rendering index (Ra) should be between 85 and 100.
In October 1957, the D-17 was introduced, followed by the D10 and the D12 in 1959, in which year Allis-Chalmers made as many as 50 model configurations of the D10, 12, 14, and 17. The Model D17 was developed as a replacement for the WD45 as a four-plow tractor. The D17's styling closely followed the smaller D14.
For example, D50 has a CCT of 5003 K ("horizon" light), while D65 has a CCT of 6504 K (noon light). This is because the value of the constants in Planck's law have been slightly changed since the definition of these canonical illuminants, whose SPDs are based on the original values in Planck's law.

The difference between ICHRAs and QSEHRAs is who they cover. While they offer similar coverage, QSEHRAs can only be offered by small businesses with fewer than 50 full-time employees. Companies of ...
D50, the mass-median-diameter in particle-size distribution measurements, considered to be the average particle size by mass D50 (film) , working title for a Tamil-language film D50 (radiotherapy) , the half maximal inhibitory dose, representing the dose of light or ionising radiation that is required for 50% inactivation of a tumor cell population
D50 in medicine is the half-maximal dose: the dose that produces 50% of the maximum response. [1] It may specifically refer to the radiation dose required to achieve a 50% tumor control probability .
