RX7s Gas Discharge Lamps
A RX7s gas discharge lamp is a high pressure gas discharge lamp, filled with metal halides. Metal halide bulbs are relatively compact and emit an excellent light. Furthermore, thanks to the ceramic technology, the color is very stable. The RX7s gas discharge lamp has the shape of a transparent glass bar with caps on both ends of the bar. The RX7s light bulb has a built-in UV filter that prevents discoloration. This category includes the Philips MASTERColour CDM-TD, the Sylvania Superia CMI-TD and the Osram Powerball / Vialox.
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.
