I don't believe there is that much saving trying to go down the 28 watt lamps or going to electronic ballasts. You may wish try going to a brighter lamp. the standard t8 stuff is 3500k, try going to 4100k and reducing to two lamps. That should not be problem because the t8's are parallel feed type lamps. If you can reduce one lamp, now that is 32 watts not 6 watts, with that you will see savings. Also try to reduce the hallways to one lamp. Many of the large retailers are do this to reduce energy costs.
