It cannot be denied that the humble light bulb is one of the modern conveniences that has changed the way we live. At the simple flick of a switch we can have instant, trouble-free illumination. I’m sure there are few among us who would care to return to using smelly, dirty animal fat candles, oil lamps or gas lighting. It has been the practice for many years to cover naked light bulbs with shades and in fact many people really did not like seeing the bulbs at all. Exposed light bulbs were only seen in industrial factories and warehouses and certainly not in home interiors. All this has now changed as we are seeing exposed light bulb fittings being used not only for hospitality lighting but for lighting in the home too.
