Liquidleds 4W Long Tube Spiral LED Bulb E27 in Ultra Warm

About this product

Few filament bulbs make an impression on scale alone. The dimmable 4W Long Tube Spiral LED Bulb delivers 225 lumens of 2000K ultra-warm light through 290mm of amber glass in an E27 fitting, replacing a traditional 25W incandescent with ultra-high colour accuracy. The spiral coil runs from one end of the tube to the other, and at this length, the filament ceases to be a detail and becomes the whole statement. Backed by a 3-year warranty.

The Amber Effect

The coiled filament runs the full length of the long tube, lit to a deep amber gold through the tinted glass. The extra length gives the spiral far more visual presence than the medium versions: a longer, slower burn of amber warmth rather than a compact point of light. At its lowest dim setting on a trailing-edge dimmer, the coil glows with a barely perceptible amber warmth, stepping back smoothly with flicker-free performance across the full range. Switched off, the elongated tube with its visible spiral reads as a deliberate sculptural object in any open fitting, with a scale that compact tubes simply cannot match.

Where It Belongs

Tall feature pendants, statement floor lamps, and double-height exposed-bulb fixtures where scale is a real part of the design brief. In hospitality, restaurant feature lighting and boutique hotel lobbies wanting a taller, more dramatic filament bulb than a medium tube can offer are natural settings, as are double-height entryways and heritage dining rooms where the bulb needs to fill a larger vertical space on its own. Loft apartments and converted spaces with high ceilings, built around a handful of exposed feature bulbs and stairwell pendants, are strong residential applications, where the extra length fills the void more convincingly than a globe.
