Choosing lighting for an interiors project can be difficult, especially when there is so much variety out there. However, once you’ve finally chosen a fitting, you find yourself lost, once again, as you struggle to decide on the most appropriate bulb for the space. The below guide explains the differences between filament and LED bulbs, hopefully making that choice much easier for you.
B22 Filament Bulbs (aka ‘Squirrel Cage Bulb’)

B22 Filament Bulbs
The B22 filament bulb is the classic incandescent bulb, intended as a decorative feature in vintage style light fittings. The low energy efficiency, short lifespan and warm, orange glow make it unsuitable as the main source of light in a room, however, dimming the bulb reduces energy consumption, while exposing the delicate filaments to make it a unique feature in your home.
B22 Filament
Need to know:
• Low efficiency
• Energy rating E
• 180 lumens
• 2300K Extra Warm
• 60W
• Up to 3,000 hours lifespan
B22 LED Filament Bulbs

Our Small B22 LED filament bulb is an energy efficient, longer lasting alternative to an incandescent filament lamp. It has a B22 bayonet cap. The colour temperature is slightly cooler, making it suitable for use in kitchens and other spaces that require brighter light. The extended lifespan makes it a good investment as replacements will be few and far between.
B22 LED Filament
Need to know:
• High efficiency
• Energy rating A++
• 750 lumens
• 2700K Warm White
• 8W
• 80W equivalent
• Up to 25,000 hours lifespan
E27 LED Filament Bulbs

Our E27 LED filament lamp is a great substitute for an incandescent filament bulb as this LED bulb has a high energy efficiency rating and warm white colour temperature, similar to the original bulb. It is perfect for decorative, mood lighting in a dining area as it is dimmable, allowing it to provide sufficient brightness while still creating a soft, ambient glow. It has an E27 screw cap.

Key points:
Lumens (lm): Brightness is measured in lumens rather than wattage. The higher the lm value, the brighter the bulb.
Wattage (W): This is the amount of energy used, not the brightness. While the brightness of incandescent bulbs can often be determined by the wattage, LED bulbs do not work in the same way, which is why we measure the lumens. A 60W incandescent bulb is comparable to an 10-12W LED bulb as LEDs give out much more light while using less energy. See table below for more information.
Kelvin (K): The colour temperature of a light is measured in Kelvins, on a scale of 1,000-10,000K; commercial and residential bulbs usually fall between 2,000-6,500K. The lower the value, the warmer the light; the below table illustrates this.
