Common extra features include adjustable-focus beams, star-cutout projection patterns, color-changing LEDs with a remote, sound-reactive modes, USB ports for power/charging, and tilt/rotation for directional projection.
Some table lamps list ETL or UL as their industry certifications/listings. At least one LED bulb entry notes it has no industry certification, though it does list compliance with federal efficiency standards.
Small lights are powered by batteries for compact flashlights, mains electricity (plug-in) for many night and table lamps, and USB power for some small projectors and desk lights.
Listings include replaceable LED bulbs (including A19 LED types), incandescent bulbs, and fixtures with integrated/non-removable LED modules.
Common specs include lumens and color temperature (for example, an A19 LED listed at 800 lumens, 2700K), listed bulb wattages (e.g., 5W for some nightlight sockets), and flashlight performance details such as beam reach (about 27 meters) and runtimes (up to about 53 hours for larger included lights).
Many table and desk lamps list dimmable controls or 3-way settings (low/medium/high or full-range dimming). Color-changing bulbs typically offer multiple light modes and remote control; some basic nightlights and simple lamps remain single on/off.
Color-changing A19 LED bulbs are controlled by the included remote (no app or Wi‑Fi required). They offer 16 RGB colors plus two white color temperatures, dimming, and multiple named light modes such as gentle, energetic, wave, smooth, and standard. The remote can control multiple bulbs from roughly up to 20 feet.
