The lamps used then would almost certainly have been carbon filament types, 16 candle power was a very common type. They used about 60 watts and gave a very dull yellow/orange light by todays standards.
A modern 60 watt lamp would be much too bright and also much whiter, and nothing like the original.
Carbon filament lamps are still available but are very hard to find. A fleabay search is of very little help since most of the results will be for modern reproductions of early tungsten lamps and not carbon filament.
Most early lamps were available frosted at an extra charge, they were however EXTERNALY frosted and this external frosting tended to attract dirt, dust, grease and finger marks. INTERNAL frosting as is still used today was a later invention.
External frosting was achieved by dipping the bulb in hydrofluoric acid, internal frosting was by filling the bulb with the acid and then emptying and rinsing it before the rest of the manufacturing process.
Inferior external frosting was by coating the bulb with various materials, the heat of operation tended to destroy or remove the coating.
I doubt that you will find a modern carbon filament bulb that is frosted. Carbon filament bulbs are expensive, and hardly anyone wants to pay all that money for a carbon filament and then to hide it behind frosting.
By 1911 it is just possible that very early metal filament bulbs were used, in that case the modern but vintage style filament lamps sold everywhere would be a passable imitation. Frosted ones are rare, reason as above.
