Satco Lighting S21348 – Frequently Asked Questions
1) How much light does the 5.5W Satco T10 LED put out, and what incandescent wattage does it replace?
450 lumens at 5.5 watts. That output sits in the range of a 40 watt incandescent, which is the typical lamp pulled out of a tubular showcase, picture light, or sign fixture. Draw drops to about one seventh of the incandescent it replaces.
2) Can I put the Satco S21348 on a dimmer?
Yes, it is a dimmable LED. Pair it with an LED-rated (ELV or forward-phase LED) dimmer rather than an old incandescent-only control - at 5.5 watts a single lamp sits below the minimum load of many legacy dimmers, which shows up as flicker or a dead bottom end of the range.
3) Is the light from this Satco T10 LED warm or cool, and will it match the other lamps in my building?
3000K, which reads as a soft warm white - warmer than a 3500K or 4000K commercial white, cooler than the 2700K of a classic incandescent. If your other fixtures are lamped at 2700K the difference will be visible side by side, so standardize a space on one color temperature.
4) Why would I pay for a 90 CRI bulb instead of a standard LED?
The 90+ CRI rating on this T10 means colors render close to natural light, which matters in retail display cases, hospitality spaces, artwork and picture lighting, and anywhere skin tones or merchandise color are being judged. Standard LEDs run around 80 CRI and flatten reds. For back-of-house or utility use the premium buys you nothing.
5) Is the Satco S21348 a clear or frosted bulb?
Frost. The glass is diffused, so you see an even glow instead of the filament-style points you get from a clear lamp. That is the version to use where the bulb is exposed in a showcase or sign and you do not want glare or visible hot spots. If you want a decorative filament look, a clear T10 is the other choice.
6) What is this Satco T10 LED bulb made of, and is the glass real glass?
Yes, real glass over a nickel plated aluminum base and heat sink. The aluminum handles thermal dissipation, which is why a tubular LED this small can run enclosed in a showcase or picture fixture. Whole lamp weighs 0.06 lb, so it puts almost no load on a socket in a hinged or swing-arm fixture.
7) Where do I find the full photometric spec sheet for Satco S21348?
Satco publishes a PDF spec sheet for the S21348 5.5W T10, and it is linked on the product record. For submittals, cite the lamp as Satco S21348, 5.5W T10 LED, frost, medium base, 90+ CRI, 3000K, 120V.
