Dusk to Dawn Bulbs

Employing the very latest microchip technology, these low-energy, mini-size 15 watt light bulbs not only use considerably less electricity than conventional bulbs, but also have the added feature of switching on automatically at dusk and switching themselves off again when day breaks. Ideal to give the impression that someone is at home even when the house is empty, you can fit them into porch or outdoor lights and, because of their compact shape, use them effectively and unobtrusively in indoor lamps and ceiling lights. The perfect replacement to existing filament bulbs they measure a mere 12cm in length and have standard bayonet fittings.
