light bulb for room

Most room bulbs use the E26 medium screw base; some decorative bulbs use the smaller E12 candelabra base. Common shapes include A19 and A15 for general use, A21 for larger fixtures, and C7 for small decorative or night bulbs.

Typical options include warm/soft white (around 2700 K) and daylight (about 5000 K). Some listings do not specify a color temperature.

Brightness in listings ranges from very low decorative values (around 16 lumens) up to about 800 lumens for common 60W-equivalent bulbs. Listed watt-equivalents span roughly 4 watts up to 60 watts.

Options include fully dimmable bulbs (full-range dimming), LED color-changing bulbs with remotes for dimming and mode control, and simpler single-setting LEDs that operate as on/off only.

Some incandescent bulbs are listed as suitable for wet locations, while several LED bulbs are marked for damp locations or specifically rated for outdoor dusk-to-dawn use.

Some bulbs offer color-changing control via a remote, automatic dusk-to-dawn sensors for hands-off outdoor operation, and rechargeable battery-backup bulbs with built-in flashlights that remain on during power outages.

Some LED bulbs are marked as meeting federal efficiency standards and list limited warranties (for example, 3-year or 5-year limited warranties). Several incandescent items state no applicable warranty and do not list a federal efficiency standard.
