Pack of 2: Full-Spectrum Incandescent Bulb – 60W E27 (Edison, Spiral ST64)

Rediscover light in its most natural form.

Our Edison-style ST64 bulb uses a traditional spiral tungsten filament to produce a beautifully warm glow and a smooth, continuous spectrum across the entire visible range, from violet and blue through to deep red.

Unlike a typical white LED, which combines a concentrated blue peak with phosphor-generated wavelengths, incandescent light is produced naturally through heat. The result is a continuous, red-rich spectrum without the sharp spectral peaks commonly found in LED lighting.

When dimmed, the filament becomes cooler and the light grows progressively warmer, reducing its blue-light output and shifting further toward amber, red and infrared. This makes it particularly suited to relaxed evening spaces, bedrooms and low-light environments after sunset.

The classic ST64 shape and glowing spiral filament provide a timeless Edison-style appearance, whether used as an exposed feature bulb or behind a suitable shade.

Why choose incandescent?

• Smooth, continuous visible-light spectrum

• Naturally warm and red-rich illumination

• No pronounced blue peak

• Becomes warmer as it is dimmed

• Authentic glowing tungsten filament

• Classic Edison-style ST64 design
