perhaps a naive question, but has anyone brought this subject up with
Industry Canada? I have a difficult time understanding why a
"commercial" product is designed to a lower standard than a
consumer/residential device. In my mind, a commercial ballast would
require more stringent emi limits given the likelihood they'd be used in
much higher concentration (office buildings, factories etc).
