Most of us are familiar with the classic pear-shaped household bulb, but what is a squirrel cage bulb? These bulbs appeared in the earliest years of the 20th century, when lighting companies were competing to develop metal filaments. The carbon or metal filament was threaded up and down using support hooks until it resembled a squirrel cage, hence the name.
Back in fashion – the attraction
Today, squirrel cage bulbs are making a comeback, with increasing popularity in restaurants, bars, and homes. Still using the classic 100-year-old design (including the dimple of blown glass) these bulbs are mesmerising to look at. Their warm-glowing filaments have a calming effect similar to a traditional wax candle, or fireplace.
Lyco sell a selection of squirrel cage bulbs in either E27 Edison Screw or B22 bayonet cap fittings. One notable thing about these bulbs is their 2000K colour temperature. This is warmer in hue than standard 2700K incandescent lamps, which helps in creating a restful mood. To emphasise their fireside effect, some models also have gold-tinted glass.
Choosing the right fitting
An often ignored aspect of choosing a light fitting is the type of bulb to be used. The perfect foil for a decorative bulb can only be an open or clear-finished fitting. The Ricky Ceiling Pendant is ideal for a squirrel cage bulb, and makes a great choice of ceiling light for stylish restaurants and bars.
The Edit Crate 4 Light Bar Pendant acts as the perfect bulb-display cabinet. This modern statement light is ideal for showing off squirrel cage bulbs, and is stunning over a kitchen island or counter. The warmth of light and gorgeous-looking bulbs will set the scene for intimate meals or midnight snacks.
Back to the future
In recent years, comparatively new technologies such as LED have forever changed artificial lighting. However, there’s still demand for the high-quality light of a filament bulb. Most incandescent bulbs have been phased out by EU legislation for their inefficiency, but the squirrel cage bulb has returned. This bewitching lamp delivers light from a bygone age, and reminds us that not everything is lost.
