The question has already been answered. But I doubt that there are equivalent lamps on the market that can produce the same amount of light of 2600 lm with 110 volts. The only thing that will work is to buy a transformer that transforms the mains voltage from 110 volts to 220 volts and can provide an output power of at least 150 to 200 watts. This will allow the two lamps to be operated with the bulbs supplied. The two lamps are not dimmable. Among other things, I also use dimmable bulbs in the two lamps, but these can only produce a maximum luminous flux of 1200 lm.

It is simply a lampshade with an on/off switch without any other electronics. I.e. the bulbs would have to support 110V. The bulbs supplied are designed for 220V.
