Yes, I think it would work since most if not all oxigen generating plants go through their sexual cycle (flowering) during the night.
What spectrum of light do your bulbs give in your refugium?
Spectums in the blue side cause vegetative growth in plants, while red causes your plants to flower or produce nodes, seeds, bulbs or whatever. This is because light during the earlier months of the year (spring and summer) have a large ammount of blue in it and this is where the plant would normaly grow heavily to prepare to reproduce in the later months of the year(autumn, fall, winter) when the spectrum turns reddish.
