My partner Joe was troubleshooting "cycling" fluorescent lights in a restaurant yesterday and replaced the electronic ballasts. The lights were 8' pairs in WP fixtures, no vents for heat to escape. They were mounted above the cooking areas in the kitchen and the old ballasts were hot enough to burn your hand.
Today they call back, same symptoms.
I say heat. Fixtures that breathe better or have higher temp ballasts may be a solution.
Agree? Disagree? Any ideas?
Thanks in advance...
