Please help. I have an old house without ground wiring. I have replace all the electrical plugs with 3prong types to accomodate our modern appliances. Recently a heat wave (over 105 degrees) seemed to cause the 4foot florescent light fixtures in my work shop to flicker and not fully light. Thinking it may be the ballasts, I replaced them all (cheap Home depot varity) I also put all new tubes T12 for the new T12 ballasts. However the same situation persisted. I went out this morning when the temp was 30 degrees cooler, all all went on without any delay. Please tell me if this is strictly due to the fact that I have no ground and/or that the ballasts have thermal protection and when it gets that hot in my un-insillated work shop the ballasts act up?? Any help and advice will be greatly appreciated. Thank you!
