Osram 20W Warm White LED Frosted GLS Bulb - Screw Cap


One of the first to pioneer energy efficient lighting, Osram have released the Parathom Advanced classic range of lamps that feature high colour consistency as well as low energy usage (around 80% less than conventional lamps). The powerful 20W LED lamp is a suitable alternative for traditional 150W incandescent lamps, and has an impressive output-to-energy-consumption ratio. Suitable for general illumination, these lamps produce a warm white colour which emits a yellow-tinged glow that is particularly well suited to domestic applications. A life expectancy of 15,000 hours means that these lamps require very little maintenance over time.
