yeah, hence the whole ansi bit (American National Standards Institute)

Not every product you use has been approved by a Standard assessment organization.. but that doesnt mean the product isnt safe.. . They run about 150 degrees cooler for starters. When is the last time a digi has caused property damage? I dont think safety should be a huge issue when purchasing a digital ballast as long as its used properly.. imho they are far more superior to any magnetic ballast and the benefits far outweigh the negatives..
