The other solutions are right in that you'd need some high power transmission to be practical

but

if you harness solar power during the day and use battery power at night, you could drive some, but not many, bulbs. More photovoltaics and parallel batteries would be needed to scale. But, it would be able to amplify the RF signal and effectively drive the bulbs by radio. I would recommend driving a near-field radio and not off of WiFi if you're going for any aesthetic effect. You could even drive it with the ambient audio (there are some integrated devices already like this, but wired).
