Where the G80 spiral sits symmetrically inside a round globe, the ST64 spiral stretches vertically through the glass — the filament appears to float inside the bulb, visible from all angles. This makes it particularly effective in single bare pendant drops and industrial wall lights where the bulb hangs at eye level and the full silhouette is on display. At 40W and 2700–3000K, the light output is warm and ambient — suited to living rooms, dining areas, and bedrooms where mood matters more than brightness. It is not a task light; for functional illumination, pair it with additional sources. The omnidirectional filament casts a soft glow in all directions with no harsh shadows.\u003c\/p\u003e\n\u003cp style=\"font-size:16px;line-height:1.8;margin:0 0 28px 0;color:#121212;\"\u003eDirect E27 screw-in replacement — no tools or rewiring required. Rated at 50,000 hours and significantly more energy-efficient than a true incandescent of equivalent brightness. IP20 — dry indoor use only, not suitable for bathrooms or outdoor fittings.

The G80 is a round 80mm globe — the spiral sits symmetrically inside a sphere. The ST64 is a tall teardrop shape — the spiral stretches vertically through the glass, giving it a more elongated, architectural look. Choose G80 for a rounder, more classic decorative effect; choose ST64 for a taller, more dramatic silhouette in pendant drops and wall lights.\u003c\/p\u003e\n\u003c\/details\u003e\n\n\u003cdetails class=\"ld-faq\" style=\"border-bottom:1px solid rgba(18,18,18,0.08);padding:12px 0;\"\u003e\n\u003csummary style=\"display:flex;justify-content:space-between;align-items:center;cursor:pointer;list-style:none;\"\u003e\u003ch4 style=\"margin:0;font-size:15px;font-weight:500;color:#121212;display:inline;\"\u003eIs the spiral filament more fragile than a straight filament?\u003c\/h4\u003e\n\u003cspan style=\"color:#b8972a;font-size:18px;font-weight:300;\"\u003e+\u003c\/span\u003e\u003c\/summary\u003e\n\u003cp style=\"color:rgba(18,18,18,0.65);font-size:15px;line-height:1.7;margin:10px 0 0 0;\"\u003eNo — LED filaments, whether straight or spiral, are solid-state components with no moving parts. They are significantly more robust than traditional incandescent filaments, which could break from vibration or impact.
