I have seen multilble ballast failures from power quality over the past few weeks. our area is experiencing a heat wave, and I am sure PQ is affected. These are 208volt 400W MH high bays that appear to be 20 years old. Customer reports 2 fixtures stopped working at the same time... (on 1 circuit) and another 3 fixtures on another circuit, later on the same day. But no other damage in this facility.
any thing that can be done to prevent this ??
(let please NOT discuss upgrading to T5 high bays)
