I have never heard of a 13 amp plug. However, each flood light would draw about 4 amps since you calculate amps by watts / volts. You just add amps to determine total load.

SAD lights are typically used for fish tanks or aquariums and these light usually generate about 73 lumens per watt. SAD lights in lamps generate more lumens then lights made for aquariums they normally generate about 10,000 lumens.
From halogen to LED you can divide by 4 to find the equivalent. Therefore an 80 watt LED would do the job.
It depends on the voltage and whether the lamps are actually 40 watts or 40 watt equivalent. Watts / volts = amps
If you have ten 20-watt lights running they take a power of 200 watts, continuously. If run for 5 hours they take 200x5 watt-hours of energy, which is 1000 watt-hours or 1 kilowatt-hour. That would register as 1 unit on a domestic electricity meter. This does not depend on the voltage of the lamps.
The voltage needs to be known to give an answer to this question.
The Malibu 4-Light Black Metal Flood Kit are made up of Four 50 Watt floodlights.
around 21,000 average 100 watt bulb is around 1400 lumens. That's 14 lumens per watt. 14X1,500 = 21,000
17000 watts per plug in

You can safely put 48 regular (incandescent) 40 watt lights on a 20 amp circuit. If at some future date you might place higher wattage lights in the circuit, you will want to limit the number of lights to 20.

About 80 lumens per watt of electric power is normal for LEDs.
