I have frequent power outages (I live in a rural area outside a city) I have a CyberPower UPS but what I want to do is have a lamp come on if I lose power and then go off when power restores. I don't know alot about electronics but I think what I want to do is simple right? Here's what I think I need to do but again I have little electronics knowledge I have a extra 5VDC/12VDC transformer that will be plugged into the surge only (When the power goes out those outlets loose power) and then a relay comes in to switch on the lamp (9W CFL which will be powered from the Battery Outlets) when the the DC 5V or 12V goes dead the relay will switch on the lamp which will get power from the battery backup outlets. I just need help with what kind of relay to get and how to wire the high and low-Voltage parts

Thanks
