I'm interested in building a sort-of sonoluminescence "light bulb" for fun. Something that could be turned on or off with the flick of a switch. Obviously, the brighter the light emitted, the better. Here are my questions: Will single bubble or multi bubble sonoluminescence produce more light? How can I get the brightest possible light? Basically the only three factors would be single or multi bubble, liquid used, and gas used, I think. How bright will I be able to get it? Enough to light up a dark room a little, or no chance?
