Liquidleds 4W Long Tube LED Bulb E27 Porcelain in Warm White

About this product

A long, smooth, white tube that glows from end to end rather than from any visible component inside it. The dimmable 4W Long Tube LED Bulb E27 Porcelain delivers 300 lumens of 2700K warm white light in an E27 fitting, replacing a traditional 30W incandescent with ultra-high colour accuracy. The fully opaque porcelain coating conceals everything inside, turning the tube's entire 290mm length into a single, even light source. Backed by a 3-year warranty.

The Porcelain Effect

The porcelain coating eliminates every trace of the LED array, spreading light uniformly along the full length of the tube with no hotspots, no variation in brightness, and no visible detail from any angle. The result is closer to a glowing rod than a traditional bulb: a consistent column of warm light that wraps gently around the fitting rather than projecting from a visible source. Switched off, the smooth, matte-white surface gives the tube a sculptural, almost ceramic quality. It looks intentional at rest, well suited to open pendants and exposed-bulb installations where the tube needs to contribute to the room even when the light is off. Its 290mm length makes this effect more pronounced than shorter porcelain variants, since there is simply more of the glowing surface on display. A trailing-edge dimmer lets brightness step back smoothly, with flicker-free performance across the full dim range.

Where It Belongs

Modern pendant clusters, minimalist chandeliers, and open lamp designs are where a long, uniformly lit tube suits the design intent better than a visible filament would. In commercial settings, boutique retail and hospitality fitouts that build a sculptural lighting scheme around a few visible bulbs, gallery and exhibition spaces where shadow-free, even light is a genuine requirement, and spa and wellness environments that want a calm, diffused glow rather than a sparkling one are strong fits. Modern bathroom mirror fittings, bedroom pendants, and residential spaces wanting consistent warm light along a long, slim profile are natural applications.
