Satco item S3917 · UPC 045923039171
This is Satco S3917, a T7 / T6.5 / bayonet lamp on a Intermediate screw (E17) base. If you are replacing a bulb, the Satco number on the old sleeve or the fixture label is the surest way to match it — order by S3917 and you get the same lamp.
Appliance and indicator bulbs: what T7 / T6.5 / bayonet means
Small tubular bulbs built for heat and vibration inside appliances. Many use a double-contact bayonet (BA15d) base rather than a screw base, so the base type matters more than the wattage when matching a replacement.

Base: Intermediate screw (E17)
Intermediate screw (E17) is between candelabra and medium — common in appliances and some ceiling fans. The base has to match the socket exactly — wattage and colour temperature are choices, but the base is a fit.
Where this lamp is used
- Refrigerators, freezers and range hoods
- Microwave and oven cavities
- Sewing machines and indicator panels
Buying more than one
Most Satco lamps are stocked in multiples and many are sold by the case. Bulbs in a shared fixture age together, so relamping the whole fixture at once keeps colour and brightness matched and saves a second trip up the ladder.
