E27 4.5 W LED rustic bulb in a vintage style, gold, warm white This brand new LED bulb achieves a high level of energy efficiency thanks to the highly efficient LED technology. Thanks to the gold-coloured glass bulb, its filament look is very reminiscent of the time when the traditional light bulb was created. The extra warm white luminous colour resembles classic candlelight and creates a warm and very cosy atmosphere.
