7W Dimmable LED Tubular Filament Bulb T30L - Clear E27 3000K

This 7W dimmable LED tubular filament bulb has a T30L shape measuring 185mm tall by 30mm diameter, with a clear glass envelope and an E27 Edison screw base. Two vertical LED filaments run the length of the tube, delivering 820 lumens of 3000K warm white light that replicates the appearance of traditional incandescent filament bulbs whilst consuming significantly less energy.

Designed for use in exposed pendant fittings, wall sconces, table lamps and ceiling pendants where the bulb itself forms part of the design, the elongated tubular profile suits industrial-style wire cages, minimalist bare-holder pendants and mid-century modern fittings. The bulb is fully dimmable, allowing output to be reduced from full 820 lumens down to a low ambient glow depending on the dimmer used. The clear glass shows the filament structure when lit and unlit.

The E27 base fits standard UK Edison screw lampholders and the 30mm diameter allows the bulb to sit within narrower pendant shades and fixture cages without protruding. At 185mm length, the bulb extends further than standard A60 shapes, so check fixture height and clearance before purchasing. The LED technology provides up to 15,000 hours rated life compared to 1,000-2,000 hours for equivalent halogen or incandescent tubular bulbs, and the 7W draw replaces a 60W incandescent output.

Is this bulb dimmable?

Yes. The bulb is designed to work with most leading-edge and trailing-edge dimmers. Dimmer compatibility can vary by manufacturer, so if you experience flickering or minimum brightness issues, test with a different dimmer model or contact us for recommendations.

What fixtures does the T30L shape suit?

The 185mm length and 30mm diameter work well in exposed industrial pendant cages, minimalist bare-holder pendants, narrow wall sconces and table lamps where the bulb is visible. Check that your fixture has at least 200mm vertical clearance to accommodate the bulb length.

How does the light output compare to a traditional incandescent?

This 7W LED produces 820 lumens, equivalent to a 60W incandescent tubular bulb. The 3000K colour temperature gives a warm white tone similar to halogen, not the cooler daylight white of some LED bulbs.

What is the rated lifespan?

LED filament bulbs typically offer 15,000-25,000 hours of rated life. At three hours per day usage, this translates to approximately 13-22 years before the output degrades to 70% of initial lumens.
