Voltage question for K8055 USB experiment board

Hi there, im wondering if someone can tell me what sort of voltages/amps i can use for an external power source for my K8055 card? I have built a disco-lights system for a dancing game, and have got the design and code working with superbright LEDs, but after much testing, i have found these will only suffice for the speakers, which flash on the beat of the music. the cabinet lights will need to be more powerfull, so what i want to use is maybe some 6 or 12 volt halogen bulbs (4 in total, plus the speaker LEDS on a resistor) - is this possible without using relays? i’m trying to keep the wiring as simple as possible.

Thanks in advance
