Filament bulbs with an E27 fitting feature visible LED filaments. This makes them look like traditional incandescent bulbs, but they consume much less energy. They are available in various shapes: pear (A60), ball (G45), globe (G95 and G125), and tube.
Amber-colored bulbs provide extra warm light from 2200 to 2500 K, while the clear versions offer 2700 K. Some models are dimmable or 3-step dimmable. The Philips MASTER Dim to Warm shifts to a warmer color temperature as you dim it, just like a traditional incandescent bulb.
