Review on ANC 4 Inch 120V IC Rated LED Recessed Low Profile Square Panel Light by Bim Cook

This is a great replacement for 40w halogen bulbs. Color and brightness look much cleaner. Although nowhere is it stated that the CRI is greater than 80+. I have a problem with a buzzing noise from power supplies. in my application. Junction boxes sit high on a shelf, out of sight. I can hear them clearly. They are on the dimmer. I connected 1 of 4 lamps to a desktop for testing purposes. It's not the dimmer. He doesn't make a sound. I could try a different dimmer or just toggle the default on/off. At the same time, they fade out well without flickering.
