SATCO Lighting S21364 8W ST19 LED, Clear, Medium Base, 90 CRI, 3000K, 120V

Yes, it dims. One caution for a retrofit: it draws 0.067A, so a handful of these on one circuit may not hold the minimum load an older incandescent dimmer needs to run smoothly. On a hospitality or restaurant job where the whole room is going to LED filament, plan on LED-rated dimmers. The lamp is not a three-way bulb, so it will not step through levels in a three-way socket.

It replaces a 60 watt incandescent. The lamp draws 8 watts and puts out 800 lumens, so you get the same light off roughly an eighth of the load. On a property with a lot of decorative fixtures, that is a meaningful drop in connected load per socket: the bulb pulls 0.067A at 120V.

3000K is warm white, the color of a soft white incandescent rather than the yellow of a 2700K vintage lamp or the neutral look of 3500K and up. At 90 CRI, colors render close to natural, which matters where finishes, food, wood tone, or merchandise are on display. Practical warning for a property manager: 3000K will read noticeably cooler and cleaner next to 2700K lamps on the same run of fixtures, so switch a whole space at once rather than one socket at a time.

Clear glass with an LED filament, so the filament strands are visible through the bulb. That is the point of an ST19 shape: it goes in open cage fixtures, pendants, and exposed-socket lighting where the lamp itself is part of the look. The 300 degree beam spread means it throws light nearly all the way around rather than in a forward cone, which suits a bare-socket pendant or a chandelier. If glare from an exposed filament is a concern in a workspace, choose a frosted lamp instead.

Rated 15,000 hours average. On a lobby or corridor fixture running 12 hours a day, that is roughly three and a half years between changes; on a 24/7 exterior or stairwell circuit, closer to a year and eight months. That is the number to plan a relamp cycle around when you are standardizing a building on one lamp.

No. The S21364 is not DLC approved, so it will not clear a rebate program that requires a DesignLights Consortium listing. Specify it on its merits, 8W for 60W equivalent output at 90 CRI, and budget the project without a DLC rebate line.

Fixed at 3000K. It is not a CCT selectable lamp, so there is no field switch to move it to 2700K or 4000K. For a distributor or MRO buyer standardizing a facility, that is actually the advantage: every S21364 out of every case is the same 3000K at 90 CRI, with no chance of a lamp arriving set to the wrong position.

Yes, it is lawful for sale in California. The lamp is also FCC compliant, which matters where a filament LED sits near AV, radio, or sensitive electronics and RF noise would be a problem.

Glass envelope on a nickel plated aluminum base. Nickel plating on the screw shell resists the corrosion that eats plain brass shells in exterior and damp sockets, which lines up with the lamp's wet location rating and its indoor/outdoor listing. It is still glass, so it is not the choice for a high-impact or vandal-prone fixture.

Satco S21364. That single number covers the 8W ST19 clear LED filament lamp, medium base, 90 CRI, 3000K, 120V. There is only the clear finish, so there is no second option code to specify on the order.
