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.

The installation is very convenient and easy to fix. The packing is also perfect and there is no extrusion damage.
