You can't calculate how many volts with that information; you could calculate the energy - 60 watts for 15 minutes is equivalent to 54,000 joules.
The electricity in lightning can have a potential of around 100 million to 1 billion volts. This high voltage is what generates the intense heat and light associated with lightning strikes.
There are no volts in a light. A light consumes power.
The effects of being shocked by 13200 volts of electricity is probably death.
