A19 Spiral Filament — The compact decorative bulb, 2700K & where it excels
The A19 spiral filament combines the most universal bulb shape with the most ornamental filament style. Where a straight filament reads as classic and understated, the spiral coils visibly inside the clear glass — creating a three-dimensional pattern that catches the eye even when the bulb is off. At 2700K, this is one of the warmest colour temperatures in the range — closer to candlelight than standard warm white, producing a deeply relaxed, amber-toned glow that suits bedrooms, living rooms, and dining areas where atmosphere is the priority. The A19 shape (approximately 60mm diameter, 110–120mm length) fits inside most enclosed shades as well as open fittings, making it the most versatile spiral filament option in the range. Unlike the G80 or ST64 spiral, the A19 does not demand an open fitting — it works wherever a standard E27 bulb fits, while adding a decorative layer that a plain frosted LED cannot. At 40W, the output is soft and ambient — not a task light, but a considered light source for spaces where the quality of light matters as much as the quantity.
Direct E27 screw-in replacement — no tools or rewiring required. Rated at 50,000 hours. IP20 — dry indoor use only. Check dimmability before ordering if your fitting has a dimmer switch.

Common questions
What is the difference between the A19 spiral and the A60 straight filament?
+
Both use the same A-shape glass envelope and E27 cap. The A60 straight filament has a clean, linear filament — classic and understated. The A19 spiral has a coiled helix filament that creates a more complex, three-dimensional visual effect. Choose straight filament for a subtle decorative touch; choose spiral if you want the filament to be a visible design element. The A19 designation refers to the filament style in this context, not a different bulb diameter.
Is 2700K noticeably warmer than 2700–3000K warm white?
+
Yes — 2700K is at the warmer end of the warm white range. Bulbs rated 2700–3000K can vary between manufacturers; a fixed 2700K is consistently at the amber end of that range. The difference is subtle but noticeable side by side — 2700K reads as slightly more golden and candlelit, while 3000K is a cleaner, slightly brighter warm white. For bedrooms and living rooms where you want the warmest possible light, 2700K is the better choice.
Will this bulb fit inside a fabric lampshade?
+
Yes — the A19/A60 shape is compact enough to fit inside most standard fabric shades. Check that the shade’s internal diameter is at least 65–70mm and that the bulb does not touch the shade material — contact between a warm bulb and fabric is a fire risk. The spiral filament will cast a warm glow through the shade fabric, creating a soft, diffused light effect.
Can I use this bulb in a bedside lamp with a switch on the cord?
+
Yes — a standard on/off cord switch is fully compatible with this bulb. It is not compatible with dimmer switches or rotary dimmers. If your bedside lamp has a dimmer built into the cord or base, verify dimmability before ordering or replace the lamp with a standard on/off switch version.
How does the spiral filament look when the bulb is switched off?
+
The spiral filament is visible through the clear glass even when the bulb is off — the coiled helix sits inside the glass envelope and catches ambient light. In an open fitting or a lamp with a clear or open-top shade, the bulb reads as a decorative object even when not in use. This is part of the appeal of spiral filament bulbs over frosted or opaque alternatives.
