LED light bulbs. LEDs (light-emitting diodes) use about one tenth of the energy for a given light output when compared with normal incandescent bulbs,instant start-up time and have a lifetime typically of 30000 hours. These bulbs use arrays of individual LED elements,each fitted with a lens that shapes the output to a broad cone. The GU10-fitting bulbs are designed for use as domestic ceiling lights running on mains electricity voltage | |
