We built our house with attached garage/aircraft hangar 18 years ago and for the high ceiling side used what was recommended at the time, I believe "metal halide" units....... see attached pic. Because 3 have died, and I never liked the buzzing sound it's time to upgrade to LED. What has been mentioned are High Bay LED lights, been told they can be suspended from existing hooks and plug into existing overhead outlets. I have just begun research welcome any recommendations regarding how many K brightness, brands etc.
