SATCO Lighting S21353 8W T10 LED, Frost, Medium Base, 90 CRI, 3000K, 120V

3000K is warm white, a touch cooler and cleaner than the 2700K of an old incandescent and clearly warmer than the 4000K neutral white common in offices and back of house. If your corridors, units or guest rooms are already standardized on 3000K, this one drops in without a visible color break. If they're on 2700K, expect a noticeable difference when the two sit side by side on the same fixture run.

The S21353 is a 90 CRI lamp, meaning color rendering of 90 on a 100 point scale against a reference source. That matters where people judge color under the light: retail and merchandise displays, hospitality guest rooms, art and picture lighting, bath and vanity mirrors where skin tone shows, and healthcare spaces. Most commodity LED sits around 80 CRI, where reds go flat and finishes look muddy. For a back of house corridor or a storage room, 90 CRI is money you don't have to spend.

8 watts at 120 volts. That's the actual draw at the socket, which is what you count when you're loading a circuit or a dimmer bank across a lot of fixtures, not an equivalency figure.

Satco S21353 is the number to give. It's the 8 watt frost T10, medium base, 90 CRI, 3000K, 120 volt, and it ships in the frost finish only. Satco uses different S numbers for each color temperature and finish in the T10 line, so quoting S21353 pins down the warm white frosted version specifically.
