The No-Salt, Lowest-
Sodium Light Meals Book
That was The No-Salt, Lowest-Sodium Cookbook. Don decided to embellish the general work with some specialties and, with his wife, Maureen, created The No-Salt, Lowest-Sodium Baking Book.

If you want a high-use light, however, especially if you want a security light for
nightly dusk-to-dawn use, they can save you money. Norelco's Steve
Goldmacher gives this economic analysis for his company's 18-watt low-pressure
-sodium light: ...
A wedge-shaped film of air between two glass plates gives equally spaced dark
fringes, using reflected sodium light, which are 0.22 mm apart. When
monochromatic light of another wavelength is used the fringes are 0.24mm apart.

Lighting for Driving: Roads, Vehicles, Signs, and Signals
Because this wavelength is near to the maximum sensitivity of the human visual
system at 555 nm, as shown by the CIE Standard Photopic Observer, the low-
pressure sodium light source has the highest luminous efficacy of all the artificial
...
Refractive index for gemmological purposes is defined in terms of yellow
monochromatic light having a wavelength of 589.3nm (i.e. sodium light), and if a '
white' light source is used, the RI reading must be taken against the yellow/green
...

The Optical rotating power of organic substances and its ...
We shall consider first the most commonly used homogeneous light, the sodium
light. Every source of sodium light gives a continuous spectrum, in which,
however, the light of the sodium lines is enormously in excess. If now, smaller
rotations ...
This is due to the sodium light of salt. If now all light but the sodium light be
removed, the prismatic colors will no longer appear. We will find two bright yellow
lines in the whole spectrum, filling exactly the places held before by the two dark
...

American chemical journal
Several considerations have led me to give these numbers for sodium light.
Among them may be mentioned: (1) the ease with which sodium light can be
obtained in any laboratory; (2) sodium light can be used with any refractometer ; (
3) some ...
