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.

TP-Link smart bulbs are not dimmerable LED, it can't work with dimmer switch.

 

Various brands of dimmerable bulbs used in mixture are likely to lead to compatibility problems, they may flicker or buzz. 

 

Hope someone can share their story.

I just installed the dimmer switch and I’m having a buzzing issue at lower levels.  Were you able to find a brand that worked?  I have the ecosmart dimmable daylight LEDs right now since they were the most affordable.  I don’t want to waste money and multiple trips to the store looking for bulbs that don’t exist...

The fixture is over a vanity and has 8 bulbs, so I think the number of bulbs buzzing at the same time is what makes the sound so noticeable.

seems that there is no compatibility list, while cause the HS220 is a dimmer switch, theoretically, as the led is dimmeable and the load is lower than the power consumption of HS220, it can work with it.
