I don't know if you can run only two bulbs at a time. The advertising says "separate cords for each function", and usually, for 4 bulb lights, that means you can run 2 bulbs or 4 bulbs, but I don't know if that is true for this one. Ask the vendor. It should give you about the right amount of light for what you are wanting to do, if you can operate it with just 2 bulbs. Does your canopy allow you to hang the light inside the canopy?
