I'm wiring my aquariumlet up for light. It's one of those standard 3x20W puck light sets, but I only need one light. I want to wire up a cooling fan using one of the other light terminals. The light set has a transformer that outputs 12V 0.5A, and each puck is 20W max. My CPU cooling fan wants 12VDC 0.08A. Presumably, the light is AC, so I've got me a bridge rectifier. I'm not sure I got the right one, it was what the guy behind the counter recommended based on my needs. It says: GI W02G 644M Even if it's not perfect, he says I likely won't burn it out. He also said though, that it will likely put out something closer to 14V. So: do I need anythnig else for this circuit? A resistor?
