Antique style replica light bulb Nice filament, the packaing says its a carbon filament, but it is most likely a single coiled tungsten filament. It has lots of support wires to keep it in the coiled shape, unlike real carbon filaments, and it is visibly coiled. Still a nice lamp. 60 Watts, longlife (number of hours not given), lumen output unknown, but not much. Keywords: Lit_Lighting

Nice filament, the packaing says its a carbon filament, but it is most likely a single coiled tungsten filament. It has lots of support wires to keep it in the coiled shape, unlike real carbon filaments, and it is visibly coiled. Still a nice lamp.

60 Watts, longlife (number of hours not given), lumen output unknown, but not much.

What is the Voltage ratings? What kind of Edison Screw does this bulb have?

I think that looks neat Cool

It's 230 V, E27 base

I bet this lamp still has a hard vaccum instead of the gas filling. Such a shape for a tungsten filament (Which is very similar to the shape of the filaments of the miniature/nightlights vaccum incandescent lamps) will cause it to lose much of its heat in a gas filled lamp by the thermal conductivity and currents of the gas and only the part of the filament that is mount up will glow. See www.lamptech.co.uk of more information about this.

Yes, it is surely a vaccum lamp. The glass doesn't get hot as it would in a gas filled lamp.
