You are not looking for low light capability, rather you want the camera not to try to make the night scene look like day.
You want a night setting that specifically lives with the inadquate lighting as opposed to compensate for (boost the sensitivity for or open up the lens for or slow down the shutter for) the inadequate lighting. This way the Osborne lights themselves will come out right (and it is impossible for people's faces to come out right at the same time). If you have manual settings you would try something like the heavy overcast day setting and shoot away.
You can practice at home by getting out a string of colored Christmas lights, plugging them into an outdoor outlet, draping them against your house, and doing some outdoor night shooting. You will probably find a camera setting that can be left the same and get good results no matter how far you stand from the illuminated string of lights.
