Satco Lighting S21309 – Frequently Asked Questions
1) Is the S21309 a warm or cool light, and will it match bulbs already in the building?
It runs 4000K, a neutral white, not the warm yellow of an incandescent candelabra lamp. If the other fixtures on a floor are 2700K or 3000K, this one will read noticeably cooler and whiter next to them. For corridors, lobbies and commercial spaces standardized on 4000K it matches; for residential chandeliers replacing incandescents, expect a visible color shift.
2) What does the 90 CRI rating on the S21309 actually get me?
90 CRI means colors render close to how they look under a reference source, so paint, wood finishes, fabric and skin tones hold up. That matters in hospitality dining rooms, retail display, healthcare exam and patient areas, and any spec that calls for 90+ CRI. Standard LED lamps commonly sit around 80 CRI, so this is the higher-fidelity option for those applications.
3) Can I run the S21309 on 120V line voltage without a driver or transformer?
Yes, it is a 120 volt lamp and operates straight off standard North American line voltage. No external driver or transformer is needed. It is not intended for low voltage 12V candelabra systems.
4) Does the frosted finish on this Satco candelabra LED hide the diodes?
The S21309 uses a frost finish rather than clear glass, which diffuses the light and softens the individual emitters so you do not see hot spots through the envelope. Choose frost where the lamp sits behind a sheer shade or is viewed directly in an open chandelier; choose a clear lamp only if you specifically want the visible filament look.
5) What exact Satco part number do I order for the 4000K frosted candelabra LED?
Order MPN S21309 from Satco. That number covers the 5.5W CA10 frost lamp with candelabra base at 90 CRI, 4000K, 120V. Satco lists adjacent S-numbers for the same lamp in other color temperatures, so confirm the number rather than the description when you are standardizing a building on one color.
