SATCO Lighting S21257 6W G40 LED, White, Medium Base, 90 CRI, 4000K, 120V

Yes. The S21257 is an enclosed rated lamp, so it can go in a closed globe or sealed fixture without voiding the rating. It also carries a Wet location rating and is listed for indoor or outdoor use, which covers covered porches, vanity globes, and exterior fixtures that take splash.

Dimmable, yes. Three-way, no. It is a single-output lamp, so if you put it in a three-way socket you will get one light level regardless of switch position. For three-way table lamps you need a lamp specifically listed as three-way.

4000K is a neutral white, noticeably cooler and cleaner than the 2700K warm white most residential fixtures use, so mixing it on the same vanity bar or fixture row will read as a mismatch. The 90 CRI rating means color rendering is high, which is what you want over bathroom mirrors, retail displays, and hotel vanities. The color temperature is fixed, not CCT selectable.

Any orientation. Burning position is universal, so base-up in a ceiling globe, base-down in a pendant, or horizontal in a vanity bar all work. The 320 degree beam spread means it throws light nearly all the way around the lamp rather than in one direction, which is what you want in an exposed globe fixture.

Yes, it is listed as Title 24 compliant, and it is FCC compliant. It is not DLC listed, so if your utility rebate program requires a DLC qualified product, this lamp will not qualify for that program.

It is an LED filament lamp in a G40 globe shape with a white finish, so the filaments are diffused rather than showing as visible amber strands. Construction is glass with a nickel plated aluminum base.

Average rated life is 15,000 hours. On a bathroom or corridor fixture running roughly 12 hours a day that is about three and a half years between relamps, which is why property managers standardize on one lamp across a floor rather than changing them one at a time.
