ST64 LED Filament Bulb E27 2W–8W — Warm & Cool White, 220V, 50,000h
ST64 Edison-style LED filament bulb with E27 screw cap, available in four wattages (2W, 4W, 6W, 8W) and two colour temperatures — warm white (2700–3000K) and cool white (6000–6500K). The visible filament gives the classic Edison aesthetic at a fraction of the energy of a traditional incandescent. Integrated LED — no bulb to buy separately.

ST64 LED Filament — Vintage look, low energy & choosing your wattage
This is the LED version of the classic ST64 Edison bulb — same teardrop shape, same visible filament, same warm amber glow, but using a fraction of the energy and lasting up to 50 times longer than a true incandescent. The key difference from the 40W incandescent ST64 in our range: this bulb is designed for efficiency first. At 2W–8W, it produces a soft to moderate ambient light — ideal for pendant fittings, wall sconces, and table lamps where the filament is part of the visual design. The filament is fully visible through the clear glass envelope, so it works best in open fittings where the bulb can be seen. In an enclosed shade, the filament effect is lost and a frosted globe LED would be a better choice. Warm white (2700–3000K) gives the most authentic incandescent feel; cool white (6000–6500K) is available for spaces where a crisper light is preferred, though it is less common in filament-style fittings.
Wattage guide: 2W for pure accent and decorative use, 4W for bedside and hallway lamps, 6W–8W for table lamps and wall lights used as primary sources in smaller rooms. Direct E27 screw-in replacement, no tools required. IP20 — dry indoor use only. Check dimmability before ordering if your fitting has a dimmer switch.

Common questions
What is the difference between this LED ST64 and the 40W incandescent ST64?
+
Both have the same ST64 teardrop shape and visible filament aesthetic. The 40W incandescent uses traditional filament technology — higher energy consumption, shorter lifespan (~1,000 hours), slightly warmer and more organic glow. This LED version uses 2–8W, lasts 50,000 hours, and produces a consistent colour temperature from the first switch-on. Choose the 40W incandescent if you want the most authentic vintage feel; choose this LED if you want the same look with modern efficiency and longevity.
Is 8W bright enough for a pendant light in a living room?
+
An 8W LED filament produces approximately 600–700 lm — equivalent to roughly a 50–60W incandescent. For a single pendant in a living room, this is comfortable ambient lighting but may not be sufficient as the sole light source in a larger room. For a multi-bulb cluster or chandelier, 8W per bulb across 3–5 sockets will produce a well-lit space.
Why is cool white available in a filament bulb?
+
Most filament bulbs are chosen for their warm amber glow, but cool white (6000–6500K) is available for spaces where a brighter, crisper light is needed — a kitchen with an industrial pendant, a home office with an Edison-style desk lamp, or a retail display. The filament is still visible, but the light output is noticeably cooler and more energising than the warm white variant.
Can I use multiple ST64 bulbs in a chandelier or cluster pendant?
+
Yes — the ST64 is one of the most popular choices for Edison cluster pendants and multi-arm chandeliers. Ensure all sockets are E27 and that the total wattage does not exceed the fitting’s rated maximum. Use the same wattage and colour temperature across all sockets for a consistent look and even light distribution.
Does the LED filament look the same as a real incandescent filament?
+
Very similar, but not identical. LED filaments are slightly more uniform and consistent in appearance — they don’t have the slight irregularities of a hand-wound incandescent filament. When lit, the warm white variant is visually very close to a traditional incandescent. The main practical difference is that LED filaments reach full brightness instantly and maintain consistent colour temperature throughout their lifespan, whereas incandescent filaments can shift slightly as they age.
