They’re sold as a taller 12-inch glitter motion lamp and smaller mood lights of about 6 inches across (smaller items list roughly 3.85 in. high by 6.0 in. wide).
They use LED lighting: the smaller mood lights feature color-changing LEDs, while the taller 12-inch model is a glitter-filled motion lamp that produces an iridescent purple glow.
They include a 15-minute auto-shutoff mode, presented as a nightlight feature in the product descriptions.
Smaller (~6 in.) mood lights are battery-powered and portable—suitable for desks, bedrooms, playrooms, or travel. The taller 12-inch glitter motion lamp is larger and intended mainly as decorative room or display lighting.
They’re sold individually (single smaller mood lights and the taller glitter motion lamp) and also as a two-pack containing two smaller color-changing mood lights.
They’re recommended for children ages 6 years and up.
No assembly is required—the lights come ready to use. LED bulbs are indicated as included for some listings; batteries are either included for certain small models or listed as required for others, depending on the model.
