I'm installing 120v LED recessed lights in a room, and I'm concerned about them wearing out prematurely. I've had bad luck in the past with florescent lights on the same circuit as the refrigerator. I think it's the power fluctuations caused by the motor stop/starts.
Similarly, I notice whole house fluctuations when the central A/C starts/stops. My theory is that the transformers and circuitry in the bulbs are vulnerable to these fluctuations, and I worry the same about the $80 fixtures.
Would an inline surge protector, placed between the wall switch and the lights, help prolong their life? I'm not interested in a whole house surge protector, since it's expensive, and the motors are on the inside.
