Answer 1

The best that we have today is, of course, petroleum based wax. The standard candle, he says, would burn 120 grains of spermaceti an hour. That's 8g. Bored Chemist worked out for us that this means that it burns 2.16mg - or about 2 thousandths of a gram - of spermaceti every second.

If we know how much energy is in a gram of this stuff we can work out its wattage, which is essentially energy - in joules - per second of the candle.
