Hum noise when dimmed. If using in a chandelier with many bulbs, i imagine it would be pretty loud. Made sure they we’re * in tight but still no go. These lights are likely not suitable for enclosed fixtures.

Energy efficient and doesn't seem to be inconvenient in anyway due to it's shape. They freshen up spaces that really need more light. I both two more for my unfinished storage area in the basement.

Two of the bulbs flicker on 3-4 parts of them. Less than four months of use, i only have three that are functioning properly. The circuit board and emitters are wide open to damage.
