We are in the process of replacing approximately 7000 lamps throughout our school district. The current lamps range from T8 to T12, all sorts of ballast magnetic, instastart, electronic. I am looking to go with an Eiko,17 Watt, ballast bypass, direct wire,dual ended lamp. Most of the district's lighting is 277 volt, and most of the rooms run off of two switches, with a shared neutral. I'm not really sure if we have a lot of voltage spikes, but I can say during a heavy lightning storm our power will dim briefly, without going out completely. Any ideas or suggestions to be aware of before starting this project? Such as surge protectors on panels, is eiko a good brand, is type B the way to go?
