The Effects of Lamp Spectral Distribution on Sky Glow over Observatories
NAVAL OBSERVATORY FLAGSTAFF AZ
Pagination or Media Count:
Using a wavelength-generalized version of the Garstang 1991 model, we evaluate overhead sky glow as a function of distance up to 300 km, from a variety of lamp types, including common gas discharge lamps and several types of LED lamps. We conclude for both professional, and especially cultural visual, astronomy, that low-pressure sodium and narrow-spectrum amber LED lamps cause much less sky glow than all broad-spectrum sources.
