best energy saving light bulbs

These bulbs are sold as replacements for 60W and 75W incandescents. Watt-equivalents in the selection include 60W and 75W, and actual energy use across models runs roughly 8.0 to 10 watts.

Most options provide around 800 lumens (typical for a 60W equivalent). Other available outputs in the selection include about 1100 lumens, 760 lumens, and a backup bulb that provides 650 lumens when in outage/backup mode.

The selection includes warm soft‑white (about 2700 K) and daylight/cool white (about 5000 K) options, tunable or variable color-temperature bulbs, and multicolor/full‑color (RGB) bulbs for vivid color settings.

Manufacturer-stated lifespans in the group vary: several options list about 13.7 years, some smart bulbs are rated around 22 years, and a dusk‑to‑dawn option is listed up to about 22.8 years (based on typical usage assumptions provided by the manufacturers).

The selection is mainly A19‑shaped bulbs with one A21 option, all using the standard Edison medium screw base (E26); overall lengths reported across models range roughly from 4.33 inches to 5.63 inches.

Dimming support varies: many bulbs are fully dimmable with compatible dimmer switches, several smart bulbs allow dimming and scene control via apps or voice assistants, and other models are single‑setting (on/off) or offer remote‑controlled color and mode presets.
