T45 LED Filament Tube Bulb E27 2W–8W — Warm & Cool White, 220V, 50,000h
T45 tubular 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 elongated tube shape with a visible straight filament suits industrial pendants, bar-style wall lights, and horizontal fittings where the bulb silhouette is part of the design. Integrated LED — no bulb to buy separately.

T45 LED Filament — Tube shape, efficiency vs the 40W incandescent & wattage guide
This is the LED filament version of the T45 tube — same elongated shape and visible straight filament as the 40W incandescent T45, but using 2–8W instead of 40W and lasting 50,000 hours instead of ~1,000. The practical difference is significant: at 8W, this bulb produces a similar lumen output to the 40W incandescent while consuming 80% less energy and lasting 50 times longer. The T45 shape is defined by its length — typically 140–180mm — which makes it the natural choice for horizontal fittings: bar pendants over kitchen islands, multi-arm wall sconces, and industrial ceiling bars where a round globe would look out of proportion. The straight filament runs the length of the tube, creating a clean linear light source that reads as both functional and decorative. At 2W, it is a pure accent bulb; at 6W–8W, it becomes a practical everyday source for wall lights and smaller pendants. Warm white (2700–3000K) suits residential spaces; cool white (6000–6500K) suits kitchens and workspaces.

Common questions
What is the difference between this LED T45 and the 40W incandescent T45?
+
Both have the same T45 tubular shape and visible straight filament. The 40W incandescent uses traditional filament technology — higher energy consumption (~40W), shorter lifespan (~1,000 hours), and a slightly warmer, 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 for the most authentic vintage feel; choose this LED for the same look with modern efficiency.
Will the T45 tube fit inside a standard pendant shade?
+
The T45 is longer than a standard A60 or G80 bulb — typically 140–180mm in length. It will not fit inside most enclosed shades and is designed for open fittings where the tube is visible. Always check the internal dimensions of your shade or fitting against the bulb length before ordering. In a bar-style or open pendant, the tube hangs freely and the filament is fully visible.
Is 8W enough for a wall light used as a reading light?
+
An 8W LED filament produces approximately 600–700 lm — sufficient for a bedside reading light or a wall light used for ambient and light task lighting. For a wall light used as the primary source in a larger room, consider pairing two wall lights or supplementing with a ceiling source. For pure ambient use, 4W–6W is comfortable.
Can I use the T45 in a multi-arm fitting with horizontal sockets?
+
Yes — the T45 is specifically well-suited to horizontal and angled sockets in multi-arm fittings. The tube aligns naturally with the arm direction, creating a clean, intentional look. 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 arms for a consistent result.
Does the T45 filament flicker at low wattage (2W)?
+
No — LED filament bulbs reach full brightness instantly at all wattages, including 2W. If you experience flickering after installation, the most common cause is an incompatible dimmer switch. This bulb requires a standard on/off circuit. If your fitting has a dimmer, verify dimmability before ordering or replace the dimmer with a standard switch.
