Vintage Filament ST64 — Aesthetic, placement & honest limits
The ST64 shape — tall, rounded, with a visible spiral filament — is the defining bulb of industrial and vintage interior styles. It works best in open fittings where the bulb is fully visible: bare pendant drops, wire cage pendants, exposed Edison clusters, and open-shade table lamps. At 2700–3000K, the light is warm and amber-toned, closer to candlelight than daylight — ideal for living rooms, dining areas, and bedrooms where atmosphere matters more than raw brightness. At 40W, this is a decorative bulb first; if you need strong task lighting, pair it with additional sources or choose a higher-lumen option. The filament design means the light is omnidirectional — it casts a soft glow in all directions rather than focusing light downward like a spotlight.
Installation is a direct E27 screw-in replacement — no tools or rewiring required. Rated at 50,000 hours, this bulb will outlast most fittings it goes into. It is rated IP20 and suitable for dry indoor use only — not for bathrooms or outdoor fittings. If your fitting has a dimmer switch, verify dimmability before ordering.

Common questions
Is this a real incandescent bulb or an LED filament?
+
This is an LED filament bulb — it uses LED technology shaped to look like a traditional incandescent filament. You get the same warm amber aesthetic as a classic Edison bulb, but with significantly lower energy consumption and a much longer lifespan (50,000 hours vs. ~1,000 hours for a true incandescent). True incandescent bulbs are being phased out across the EU under energy regulations.
Will the filament be visible in my fitting?
+
Yes — the ST64 has a clear glass envelope, so the spiral filament is fully visible when lit. This is intentional: the bulb is designed to be seen. It works best in open or cage-style fittings. In a fully enclosed shade, the filament effect is lost and a standard LED globe would be a better choice.
How bright is a 40W filament bulb — is it enough for a room?
+
A 40W LED filament produces a soft, ambient glow — enough for mood lighting in a living room or dining area, but not sufficient as the sole light source in a kitchen or workspace. For rooms where you need functional brightness, use this bulb as a decorative accent alongside ceiling or task lighting.
What fitting types work best with the ST64 shape?
+
The ST64 suits any open E27 fitting: bare pendant drops, wire cage pendants, industrial wall lights, and open-shade table lamps. It also works well in multi-bulb chandeliers and Edison cluster arrangements. Avoid fully enclosed shades — the filament effect is the point, and enclosing it defeats the aesthetic.
Does the ST64 bulb get hot to the touch?
+
LED filament bulbs run significantly cooler than true incandescent bulbs, but the glass envelope does warm up during use. It should not be touched while lit or immediately after switching off. This is normal and does not affect performance or safety under standard indoor use conditions.
