Premier A19 10W RGBW Bulb
Configuration (old format, will be converted to new template when applied)
See Tasmota documentation on how to configure RGBW lights to your needs.
Bought at Autozone, Dahlonega, USA. I could not find a photo on the internet, so I took a picture of my lightbulb. The photo is Public Domain.
Also, other than the PDF instructions, I could not find information on their website. I did buy these products at Autozone though, and it has Premier (with the same logo as Premier Accessories) printed on the devices.
