Bare Philips HPI-T 400W burner Complete spectral distribution of the light emitted from a bare HPI-T 400W burner ran on a 400 W HPS ballast. In this condition the arc tube radiates 38.9 klm and its light color is characterized by a CCT of 5462 K for a CRI of 52.6 Ra8. This high color temperature combined with a mediocre color rendering is caused by a too low burner cold-spot temperature. Keywords: Miscellaneous
