These aren’t the same as the Ultra Definition series they mentioned, unfortunately. They lack the dim to warm feature that makes those desirable. RAB is the only manufacturer I’m aware of that makes 3000k dim to warm A19 bulbs for the US market.

The RAB bulbs have a weird stair step warm-then-cool when turning on and off. They also have a huge non-linearity when dimming. That makes the Philips version more desirable, but they’re 2700k.
