Current surges knocking out LED drivers

An installation of LED lamps in refrigerated space (inside reach-in glass doors on grocery cooler) has seen high failure rate of LED lamp drivers (AC to DC). LED lamps are powered by a branch on the same phase (but separate branch circuit) as anti-sweat door heaters totalling 30A. Separate installation of controlls on door heater circuits have solid state relays opening and closing the 30A door heater circuits on a frequency of about 1HZ.

Could the voltage spike associated with each OFF cycle of the door heater circuits be causing the LED drivers to fail even though they are on a different branch circuit? e.g. the voltage spike would have to be traveling through the service panel and out the LED light branch to reach the drivers. It is a small store with not a lot on the panels (not a lot of other systems to damp out the voltage spike).
