Part of the point is to learn from your experiences. Therefore, this IS worthwhile to try.
Besides, do the math. Normally you might leave your daylight bulbs on, say, 6-8 hours min to well light your corals? How about instead, leave half the lights on 12 hours and have it on a light rail. Anyhow, it does work.
If it didn't, light rails wouldn't be so available at hydroponics store.
