Mechanical and Electrical Equipment for Buildings
If a diffusing coating is added to a sodium-vapor lamp, the entire glass envelope
becomes the light- emitting source. This reduces lamp luminance, and therefore
glare potential, drastically but also reduces output (and efficacy) by 6% to 8%.
Walter T. Grondzik, Alison G. Kwok, Ben Stein, 2011
High Quality Content by WIKIPEDIA articles! A sodium vapor lamp is a gas discharge lamp that uses sodium in an excited state to produce light. There are two varieties of such lamps: low pressure and high pressure.
