Has anyone found any led bulbs that don't flicker, hum or buzz when installed with the HS220 and dimmed? I have 2 HS220s controlling 11 recessed lights in the living room. I've tried varying BR20 bulbs from brands, Philips (they Buzz), Sunco (they flicker) and Giant Eagle (they buzz). I initially thought I found the holy grail of bulbs in the Philips when I installed one and heard no buzzing and experienced no flickering. However when 11 of them were installed the buzzing is quite audible when dimmed. I'm due to try some Hyperikon bulbs as well.
Does anyone have any recommendations on a no buzz, hum or flicker solution? I've tried tech support with regards to the HS220 and the only bulb recommended was the TP-Link smart bulbs which defeats the purpose of having a smart switch.
Further, does anyone know the type of dimmer technology used in the HS220? Is it similar to the ELV dimmers that are in the Lutron products? This information does not appear to be disclosed in the supporting information on the HS220 and tech support has not been helpful in identifying the type of dimmer used.
