These decorative light bulbs, popular though they were, were deemed to be too inefficient by the European Union and subsequently banned in February 2016.
For those of you already lamenting the demise of these light bulbs - never fear. Their enduring popularity led Crompton to develop this new range of LED ST64 equivalents.
Each light bulb in the range delivers form and function equally with the same gorgeous, retro styling no longer stymied by the restraints of outdated filament technology.
The tungsten filaments found in these older light bulbs have given way to four LED filaments, resulting in a gorgeous, traditional aesthetic that belies the light bulb's ultra-modern specification. These filaments, albeit similar in appearance, are much more efficient and robust than their traditional counterparts. Where a traditional light bulb might use approximately 40W to produce 410 lumens, these modern LED light bulbs use just 5W. This - coupled with the light bulb's vastly superior nominal lifetime of 10,000 hours - has the potential to reduce lighting bills by up to 90%.
The antique-bronze finish applied to this ST64 squirrel cage light bulb lends it an extra warm white colour that really reinforces its vintage aesthetic, particularly when the light bulb is dimmed to lower levels.
What are Antique Filament light bulbs?
Elegant yet industrial, intricate yet masculine, antique filament light bulbs evoke the memory of Edison's early design and recreate the aesthetic of the Victorian age. Hung from the ceiling in exposed clusters or used in singular, shaded fittings, these light bulbs manage to be both simple and sophisticated with the raw beauty of the filament elevated to the fore of their design.
Features a BC-B22d bayonet (22mm) cap base.
