Vintage look, LED engineering
The LUMIFARO ST19 LED bulb keeps everything people love about the old tubular Edison bulb — the tall teardrop silhouette, the clear glass, the visible filament — while replacing the fragile, heat-spewing wire with LED filament technology. Because the glass is clear rather than frosted, this is a bulb meant to be seen: in open cages, bare-socket pendants, wire fixtures and vintage-style sconces, the filament pattern itself becomes the decorative element. The classic proportions, 140 mm tall and 64 mm in diameter, keep it in scale with most decorative fixtures designed for the ST19 shape.
Light quality and distribution
This bulb produces 500 lumens at 3000K, a warm white that reads as cozy and residential rather than clinical. Its CRI of 80 keeps wood grain, brick, skin tones and plated food looking natural — important in dining rooms, cafés and retail displays. The photometric data shows an average beam angle at 50% of 323.8°, an almost fully spherical spread: light wraps around the bulb rather than being funnelled into a tight spot, which is exactly what you want from an exposed decorative bulb. The spec sheet's illumination table confirms how that output behaves with distance, showing average and maximum lux values from 1 m all the way to 10 m.

Electrical and dimming notes
Wiring is straightforward: this is a 120-volt LED bulb that drops into a standard line-voltage socket, no driver or transformer to add. On the dimmable side, the manufacturer notes that these LED bulbs work with most dimmers and that dimmers are generally rated for a maximum of 150 watts of LED bulbs — with a strong recommendation not to exceed 80% of that capacity, to avoid flicker when the dimmer is at its lowest setting. Because each ST19 draws only 5 watts, a single dimmer can comfortably carry a long run of decorative sockets, which is a real advantage for a chandelier, a row of pendants over a bar or a stairwell circuit. Keep the total load within the recommended margin and the dimming curve stays smooth and quiet.
Where it earns its place — and documentation
Think of every fixture where the bulb is part of the design: a trio of glass pendants over a kitchen island, a black metal cage sconce in an entry hall, a farmhouse chandelier in a dining room, bare-socket string lights over a patio, or the exposed lamp holders behind a café counter, a bakery display or a barber station. Property managers and contractors appreciate the 5-watt draw and the 2-year warranty when a building has dozens of decorative sockets running long hours.
