SATCO Lighting S21258 8W G40 LED, Clear, Medium Base, 90 CRI, 3000K, 120V

Yes. The S21258 is wet location rated and listed for indoor or outdoor use, so it can go in an exposed porch fixture, a covered entry, or an outdoor string setup on 120V. It is also enclosed rated, which matters on sealed jelly-jar and vapor-tight fixtures where a non-enclosed-rated LED cooks itself and dies early.

Yes, the S21258 is a dimmable LED filament lamp. Filament LEDs dim smoothly with warm-toned output, which is why they get specified for exposed-bulb vanity bars and pendants. It is not a three-way lamp, so it will not step through the levels in a three-way socket the way a 30/70/100 incandescent does.

3000K is warm white, a touch cleaner and brighter looking than the 2700K of an old incandescent globe but still on the warm side. In a vanity or guest bath it reads as crisp without going blue. Paired with 90 CRI, skin tones and finishes render accurately, which is the reason hospitality and multi-family specs call for 90 CRI at the mirror. If you are matching existing incandescent globes elsewhere in the building, 2700K is the closer match; this one is a single fixed color, not CCT selectable.

Burning position is universal, so it runs base up, base down, or horizontal with no effect on rated life. That covers pendants, wall sconces pointing sideways, and open vanity bars over a mirror. Rated life is 15,000 hours.

Yes, the 8W G40 is Title 24 compliant, which is what a California multi-family or residential job needs for the lamp to count toward high efficacy. It is also FCC compliant. It is not DLC listed, so it will not qualify under DLC-based commercial rebate programs.

The S21258 is clear glass with a visible LED filament, so the filament is exposed and it is meant for fixtures where the bulb is part of the look: open vanity bars, cage pendants, exposed sconces. Light spreads 300 degrees, close to all around, so it lights a room evenly rather than throwing a beam. If the bulb sits at eye level in a seated area and glare is a concern, a frosted or white G40 is the better call for the same socket.

The lamp is glass with a nickel plated aluminum base. Nickel plating on the screw shell resists the corrosion and socket seizing you get from plain brass-plated shells in damp baths and exterior fixtures, which matters if you expect to relamp that socket again in a few years. The lamp is wet location rated for those spots.
