SATCO Lighting S28602 4W, JCD LED, 3000K, G9 Base, 120-130V, Carded

The S28602 is a JCD-shape LED with a G9 base, so it drops into any fixture built for a G9 bi-pin bulb, the two-loop-pin base common in small chandeliers, sconces, under-cabinet pucks and accent fixtures. Two things still decide the swap: line voltage and physical clearance in the socket cup. It runs on 120-130 volt line power, so it goes straight into standard North American 120V circuits with no transformer. If the fixture is a 12-volt G4 or GY6.35 low-voltage type, this is the wrong bulb.

3000K, which reads as a soft warm white, a bit crisper than the 2700K of a classic incandescent and well short of the neutral 3500K to 4000K range. If the rest of the fixture or the room is running 2700K, this one will look slightly whiter side by side. For a multi-lamp chandelier or a run of sconces, lamp the whole group at 3000K rather than mixing.

The S28602 draws 4 watts. G9 halogens in decorative fixtures typically ran 20 to 40 watts, and an LED at 4 watts is doing the work of a small halogen in that family, not the big one. If the fixture was lamped at the high end, expect a step down in output; at the low end it is a close match. The wattage cut is where the value is on a fleet of chandeliers or a lobby with dozens of G9 sockets.

Dimming performance is not something to assume on a G9 LED. The S28602 is specified as a 4 watt, 3000K, 120-130 volt G9 lamp, and dimmer compatibility is a separate rating. If the fixture is on a dimmer, plan on either confirming the lamp's dimming rating before you commit a large order, or lamping dimmed circuits with a bulb specifically listed as dimmable. Putting a non-dimmable LED on a leading-edge dimmer gives flicker and shortens life.

Clear. That matters more on a G9 than on most lamps, because these sit in open chandelier arms, exposed candelabra fixtures and glass-shade sconces where the bulb itself is visible. A clear lamp gives you the sparkle and visible filament-style look through cut glass or a clear shade, and it also means a bare socket will show the LED chips. In a fixture with no shade at eye level, that is the trade.

JCD is the shape designation for the squared-off capsule body that pairs with a G9 base and runs on line voltage, 120-130 volt in this case. JC generally refers to the smaller low-voltage capsules on G4 or GY6.35 pins, which need a 12-volt transformer behind them. Look at the socket: two thin straight pins is low voltage and the wrong family, two looped wire pins spaced for a G9 is what the S28602 fits.

Carded, meaning individually blister-carded for retail-style handling rather than loose in a bulk sleeve. For a property manager stocking a maintenance cart or a contractor pulling a handful for a punch list, that packaging keeps the pins protected and the lamps identifiable on the shelf. The manufacturer part number is S28602.
