So far this year I've replaced most of my fluorescents with 30 of the 4'-LED tubes from Rockler. When they go on sale again ($8 ea.) I'll replace many of the remaining fluo-tubes I have in my shop. These are the "plug & play" type. I have a 4-tube (2- ballast) fixture right above my lathe. I just had to replace the ballast last week. At $20 a pop I hope all my other ballasts hold up, because I have six more 4-tube industrial fixtures in my shop that were removed from a commercial demolition and are probably at least thirty years old.
