led light strips power consuption
From the data sheet you linked: "Working Current/meter: 0.35-0.4A"
So 5 meters should be just about 2 amps.
So I don't see a problem - the data sheet is wrong about power, but right about current.
I suspect that the data sheet is claiming that the light output (1440 to 1560 lumens) is equivalent to a 95 watt incandescent. Since a pretty standard value is 1600 lumens for a 100 watt bulb, this seems about right.
