Ballasts: 12 of 21
.
What is electromagnetic interference?
Electronic ballasts, because of their high frequency operation, generate a small amount of interference with radio reception, etc.. The federal government mandates limits on the amount of EMI generated by appliances etc.. and all ballasts are required to stay within these guidelines
How can I further limit EMI?
However, in special situation—laboratories, hospitals etc..—where sensitive electronic equipment is used, it may be necessary to specify further reduction in electromagnetic interference. This can be achieved by metal shielding of fixtures and ballasts
