Thats because there's a big inductive load in the starter.
The voltage induced by the ballast or starter to start the
Flourcent lamp is higher than the input voltage.
The motors on the pump or power head are not that much different from the 
computer fan motor on the ps and cpu.
The filiment in your light bulb is a very low resistance
load until it heats up. For a very short time the current is high and it 
probally overloaded the electronics in your ups. Then its resistance goes 
high and reduces the current, unless its a backwound filiment.
Watts are Watts, nothing more than a function expression of power
output of the device.
The loads mentioned by the mfg. and warned about are reactive loads. 
Inductive or capacitive!
In either case the ups is not suitable for any substained
power outage. It wont last long enough.
I hope you do win the lotto, maybe you could pass around a few bucks???:)
