100w a19 bulb

Most listings show about 1,600 lumens output while actual power draw is listed as either 12W or 15W depending on the model.

Single-color options commonly include 3000K, 4000K and 5000K. Some selectable models list five temperatures: 2700K, 3000K, 3500K, 4000K and 5000K.

They use the standard Edison medium screw base (E26) and are A19-shaped bulbs.

Some listings show a CRI of 80, while selectable or higher-accuracy models list CRI 90.

Overall lengths in the listings range from about 4.29 inches to 4.65 inches.

They’re described as general-purpose bulbs for fixtures like floor lamps, ceiling fans, pendants, sconces, post lights and standard rooms; many listings also note a damp-location rating for outdoor use.

Listings note these are 100W-equivalent bulbs that meet federal efficiency standards, contain no mercury, and use 12W or 15W of actual power—reducing electricity use compared with a 100W incandescent.
