It is a high intensity light or lamp that cast even illumination over a broad area.

Spotlight is a specific spot, floodlight is a large area, thus the use of SPOT or FLOOD.

So that aircrafts do not crash into it.
The most common use of a floodlight is in today's society to illuminate outdoor playing fields for sports such as football, basketball, cricket, rugby and many other fields.

A spotlight has a narrow beam that concentrates light on a small area. A floodlight is built so that the light spreads over a wide area. With a spotlight you will see things further away in front of you however it will leave everything beside you in the dark with a floodlight the reverse is the case.
Standard running lights. A floodlight on the mainsail is just a good, wise tactic.
Watts = Volts x Amps for an incandescant bulb. So Amps = 600/120.
The spotlight bulb has a different pattern cut into its lens that concentrates the light output into a tight central pattern. A floodlight lens pattern distributes the light output to a larger outside diameter there by spreading the light into a wide flood pattern. The spotlight has a higher light intensity output than the floodlight output.
If the light is operating at 110 volts, and P = I x E, then I = 300/110, or 2.5 amps.
