In Germany, all lodges use candles. Three on the altar and one on each column. In higher degrees the number of candles grow and oil lamps add to the candles in some degrees. The highest number is our VIII° festive work with about 100 candles. I never saw candles waxing the bible, but from time to time they are waxing the floor. I even bumped into a column myself and hit down the candle. But a lightbulb can burn through too during the ritual. The risk is a bit higher, that's for sure, but in our ritual the light is carried by the WM and the wardens from the altar to the columns, and they spread light in the truest sense of the word.
We do have electric light for non-ritual lighting, so older brothers can find their seats and the ardens can read their ritual (it is read here, not memorized).
