Crompton ST64 LED Light Bulb Dimmable B22 5W (40W Eqv) Warm White Vintage
Is it really an LED, or is it a traditional incandescent bulb? You'd certainly be forgiven for asking the question.
The four slender LED filaments clearly visible inside this ST64 squirrel cage bulb are designed to mimic those of the popular antique traditional bulbs that were banned by the European Union in February 2016.
In the wake of this wide-ranging ban on inefficient incandescent light bulbs, manufacturers have been forced to find a way of preserving the popular antique aesthetic while abiding by the EU's definitions of efficiency.
The LED ST64 bulb pictured above is part of a range that has been developed by Crompton Lamps to do exactly that.
The result is a bulb that offers the best of both worlds, with the gorgeous aesthetic of Edison's traditional design powered by 21st century electronics.
Where this modern LED bulb only uses 5W, the older versions it replaces would have used around 40W to produce the same 410 lumens.
Add to this a far superior nominal lifetime of 10,000 hours (as opposed to 1,000 hours) and this LED bulb has the potential to reduce your lighting bill by up to 90%, without compromising your decor in any way.The antique-bronze finish that has been applied to the envelope of this particular bulb reinforces its vintage appeal yet further, lending it an extra warm white glow that looks even more authentic when the bulb is dimmed.
