The Parathom Advanced classic range of lamps from Osram feature high colour consistency thanks to narrow binning, as well as low energy consumption (around 80% less than conventional lamps) due to their LED technology. If you need a powerful lamp, then the 21W LED is a suitable alternative for a traditional 150W incandescent lamp, and is easy to retro fit due to its compact design. The Parathom Advanced classic lamps are suitable for general illumination and the warm white colour emits a glow particularly well-suited to living areas in homes, care homes or nursing homes.
