Abstract

Spectral and photometric time-averaged measurements at nominal lamp power rating are presented for pulse operated HPS lamps of several manufacturers and different sodium concentrations. The choice of pulse and cycle parameters, which determine the optimal ratio between pulse and simmer powers are discussed. Spectra at various operating conditions as well as curves relating CCT, luminous flux and color rendering index with pulse cycle parameters are presented. Acoustic emissions were measured and are briefly discussed.
