This is not a huge sale, saving you about $5 on this four pack, but hey, it’s still a sale. They are dimmable 16 million colors and warm to cool whites(2500K-6500K). Set your bulb to automatically adjust its color temperature to match natural light patterns from dawn to dusk. Explore endless lighting possibilities to create your favorite light effects for everything from a dinner party to a late-night study session. Great for holiday decorations. Monitor real-time energy usage. Drive down energy consumption without losing quality (60 W equivalent). Use timer or schedules to set your lights to automatically turn on and off whenever you want, such as waking up with a soft glow in the morning with sunrise offset. These are pretty good smart light bulbs, sure they aren’t super bright like a 75W or 100W light bulb, but these are going to be bright enough for most rooms.
