Satco Lighting S21375 – Frequently Asked Questions

1) Will the Satco S21375 LED fit a double contact bayonet (BA15d) socket?
Yes. The S21375 is built with a double contact bayonet base, so it drops into a DC bayonet socket, the two-pin push-and-twist type with two bottom contacts. It will not fit a single contact bayonet or a medium screw socket.
2) Can I run the Satco S21375 on 120V building power without a driver or transformer?
Yes. It is a 120 volt lamp, so it wires straight into standard line voltage. No external driver, transformer or low voltage supply is needed. Do not put it on a 12V or 24V circuit.
3) What light output and color does the Satco S21375 T6.5 LED bulb give?
400 lumens at 4000K, a neutral white that reads cleanly against both warm and cool surroundings. The glass is clear, so the filament-style source stays visible and the beam is a bit more sparkly than a frosted bulb would be.
4) How much energy does the S21375 save over the incandescent DC bayonet lamp it replaces?
It pulls 4 watts for 400 lumens. For a property manager swapping out incandescent indicator and fixture lamps across a building, that is a large per-socket cut in draw while keeping the same bayonet socket and the same 120V circuit, with no fixture rewiring.
5) What shape is a T6.5 bulb and where does it get used?
T6.5 is a slim tubular envelope, roughly 6.5 eighths of an inch across, about 13/16 inch in diameter. Combined with the double contact bayonet base and 120V operation, the S21375 suits tight tubular fixtures, exit and indicator applications, and decorative housings where a wider A-shape or globe lamp will not physically clear.
6) What part number do I order for the Satco 4W T6.5 DC bayonet LED in 4000K?
Order Satco S21375. That MPN covers the 4 watt clear T6.5 LED with double contact bayonet base, 4000K, 400 lumens, 120V. There is one configuration, so nothing else needs specifying on the order.
7) Is the Satco S21375 only sold in clear, or is there a frosted version?
Clear is the only finish offered on the S21375. If your application needs diffusion to hide the source, a clear lamp behind a frosted or diffused fixture lens is the way to get it here.
