Brightness ranges from about 800 lumens for some A19 bulbs up to 4,200 lumens for the 2'×2' flat panel, with many bulbs listing around 1,100–1,200 lumens.
Most smart bulbs use the standard Edison medium screw base (E26). Common shapes include A19 and BR30, and the selection also includes integrated/non-removable LED fixtures.
The selection includes multicolor bulbs that offer millions of colors, plus tunable-white options that adjust across warm-to-cool color temperatures.
Many bulbs support full-range dimming; others list distinct preset brightness levels or simple on/off control. A few require compatible in-fixture dimmers or a compatible hub to access dimming features.
