Satco Lighting S28787 – Frequently Asked Questions
1) Can the Satco S28787 A19 LED bulb be used on a dimmer switch?
No. The S28787 is a non-dimmable lamp, so it should only go in fixtures on a standard on/off switch. Put it on a dimmer and you can get flicker, buzz, or early failure. If the room has dimmers, specify a dimmable A19 LED instead.
2) Is 4000K too cool for apartment living spaces?
4000K reads as a neutral to cool white. It suits corridors, laundry rooms, stairwells, garages, back-of-house and work areas where you want a crisp look. For apartment living rooms and bedrooms where tenants expect a warm residential tone, a 2700K or 3000K lamp is the better call. The S28787 is only built in 4000K, so standardizing a building on it means standardizing on that cooler appearance.
3) What voltage does this Satco A19 LED run on, and can I use it in a commercial 277V fixture?
The S28787 is a 120 volt lamp. Use it on standard line-voltage 120V circuits only. For 277V lighting circuits common in commercial panels you need a lamp rated for that voltage, or a 277V-rated fixture with an integral driver.
4) Is the Satco S28787 clear or frosted?
Frost. The soft white coating diffuses the LED sources so you do not see hot spots or individual diodes through a shade or an open fixture. If you need a visible-filament clear look for decorative exposed sockets, this is not that lamp.
5) Is the color rendering on this bulb good enough for retail or healthcare spaces?
CRI is 80+, which is the standard grade for general-purpose lighting: corridors, offices, common areas, storage, and MRO work areas. Where color accuracy is specified, such as retail merchandising or patient exam areas calling for 90 CRI, you should spec a high-CRI lamp instead.
6) Where can I get the spec sheet for Satco S28787?
Satco publishes a PDF spec sheet for the S28787 covering the lamp's electrical and photometric data, available at https://media.distributordatasolutions.com/269/xlsx_satco/ab1dfc761bff329c3bc4101d9943b4cbb243f858.pdf. Useful if you need documentation attached to a submittal package.
7) How much does a Satco S28787 A19 LED weigh for bulk shipping estimates?
Each lamp weighs 0.11 lb, so a case quantity stays light. Worth knowing if you are palletizing a building-wide relamp, since the box volume, not the weight, will drive your freight.
