    Flicker of Modern Lighting Technologies Due to Rapid Voltage Changes by Stefano Lodetti, Izaskun Azcarate, José Julio Gutiérrez, Luis Alberto Leturiondo, Koldo Redondo, Purificación Sáiz, Julio J. Melero, Jorge Bruna

    Published 2019-03-01
    “…The obtained results show a high dispersion in the response of the modern lighting technologies and high values of flicker perception, although with a lower sensitivity than the incandescent lamp. The results led the authors to propose the definition of a new immunity test to be added to the lamp immunity protocol IEC TR-61547-1, to ensure that newly produced lamps cause limited irritation to grid users.…”

    Observing Nightlights from Space with TEMPO by James Carr, Xiong Liu, Brian Baker, Kelly Chance

    Published 2017-06-01
    “…A spectral retrieval algorithm will estimate the contributions from sources in a spectral library to map out the usage of various types of lighting (e.g., Hg vapor, high and low pressure Na vapor, LED, fluorescent, and incandescent) over North America. We calculate the sensitivities of such nightlight retrievals using the measured properties of our flight detectors and optics, and conclude that TEMPO will complement well the VIIRS Day-Night Band for the study of artificial lighting at night from space by offering a new and powerful capability to discriminate between lighting types.…”
