Osram HCI-T (Powerball)
The Osram Powerball HCI-T lamps have an excellent color display, are very efficient and have an excellent color stability. The average lifespan of these gas discharge lamps is around 15.000 burning hours. Due to the ceramic design, the Powerball HCI can withstand more heat than the HQI (Powerstar) gas discharge lamps. Thanks to the UV filter used in the lamps, the compact Osram Powerball HCI-T bulbs are well below the maximum permitted UV values according to IEC 61167. The filter protects illuminated objects from discoloration.
The colour code is a combination of the colour rendering index (CRI) and the colour temperature (K). The first number refers to the CRI (1 = very poor colour rendering, 9 = maximum accuracy). The second and third numbers refer to the colour temperature. For example, a light with a colour code of 830 has very good colour rendering and produces a warm white light.
