ECN Forum Forums General Topics of the Trade General Discussion Area Is that ballast Bad?

Sorry, I missed the efficiency question in my first post.

Based on the fact that the leakage usually indicates excessive temperature mainly caused by some internal fault, it very likely that the ballast is inefficient and drawing more than rated current. You could check actual current draw against the marked rating, assuming the label is still readable.

Such a ballast would tend to cause me greater concerns than how efficient it is.
