Power supply specs

Hi all, I am looking to add some lighting to my printer off one of the 12v connections on the power supply.

Here is the power supply: [folgertech.com]

as can be seen in the link :
Output Voltage: 12V DC
Output Current: 0~30.0A

I am curious is that 30A is per output connection, or the PSU as a whole? I currently have 2 of the 3 12v outputs connected to the ramps, and the other one is connected to the extruder fan so it is always on. I am just curious if I will be able to put a ~7.5 Watt LED lamp on the 3rd connection in addition to the fan. According to the reviews on the lamp it only draws 0.5 amps, and the specs for the lamp say it can draw up to 0.8 amps.

Here is the lamp [www.amazon.com]

Yup I am an idiot, 12v * 30A = 360W.... which is what its rated for. I think it could power that LED lamp.

Add to that, the supply does not have three outputs - it's simply three sets of screws connected to tha same output . . .
