The Easter service is held at night and the holy light is given by our priests to the people waiting outside the church and then at midnight all candles are lit and we sing hymns, one basically that says "Christ is alive, resurected from the dead, beat death etc etc". We move our candles and we kiss the kiss of love. That's why all godparents buy their godkids ( I have 3!!! ) candles for Easter. These are special candles, decorated, with color, mine was pink and had little things hanging on pink ribbons...
Did you know that every year at Jerusalem, at the Holy grave, the light appears on its own, out of nowhere, shoots in the cave, banging from wall to wall as in sci-fi movies and only when an Orthodox priest of the "Greek" (not Greek in the nation sense of the word) church is there? Once an Armenian priest went in to get it after fights etc, and he waited until next day and nothing happened. At least that's what I heard the other day. Funny, huh?
For us Easter is more important than Christmas and we celebrate it more.
