SATCO Lighting S12402 5W LED A15, Clear, Medium Base, 4000K, 90 CRI, 120V

Both are allowed. The 5W A15 is an enclosed rated lamp, so sealed globes and jelly-jar fixtures are fine, and it carries a Wet location rating for indoor or outdoor use. It also burns in any position, so base-up, base-down or horizontal sockets all work.

The Satco S12402 draws 5 watts and replaces a 40W incandescent, delivering 450 lumens at 120 volts. Current draw is 0.042A, so on a 15A circuit the load per lamp is negligible if you're relamping a whole building.

4000K is a neutral white, cooler and cleaner looking than a 2700K warm incandescent and warmer than a 5000K daylight lamp. At 90 CRI color rendering is high, so finishes, paint and skin tones read accurately, which is why it gets specified in corridors, lobbies and healthcare spaces. If the rest of your fixtures are 2700K or 3000K, this lamp will look visibly whiter next to them. Color temperature is fixed, not selectable, so order the same 4000K across the group you want to match.

Dimming is supported on the 5W A15. Three-way is not: it's a single-level lamp, so in a three-way socket it will light at one output only. For three-way table lamps you need a lamp built for it.

Yes, it's an LED filament lamp behind a clear glass lens, so the filament strips are visible, the way a clear incandescent looks. That suits open-shade fixtures and exposed sockets where the lamp is part of the look. If you want the light source diffused and hidden, pick a frosted or satin lamp instead.

Close to it. Beam spread is 320 degrees, so output is nearly omnidirectional, which is what you want in a chandelier, ceiling fan kit or open sconce where the lamp has to light upward as well as down. It's not a directional reflector lamp, so don't use it where you need a controlled spot.

Yes. Satco lists the 5W LED A15 as lawful for sale in California. It is FCC compliant as well. It is not DLC listed, so if your utility rebate program requires a DLC qualified product, this lamp won't qualify for that incentive.

Rated average life is 15,000 hours. On a 12 hour per day common-area schedule that works out to roughly three and a half years between relamps, which is the main reason property managers swap incandescent A15s out of stairwell and exterior fixtures.

Construction is aluminum and glass, with a glass lens. Aluminum in the base section carries heat away from the LED; the glass envelope is rigid and won't yellow the way some plastic lenses do, but it is breakable, so for areas where impact is a concern a polycarbonate-lens lamp is the safer spec. Each lamp weighs 0.05 lb.
