Purpose & Fit

The Satco S3911 is a 15W incandescent indicator lamp with a T7 tubular envelope and an E17 intermediate screw base.

Accessory Impact

No accessories, adapters or software are included with this bulb; the package contains only the lamp itself. Buyers who need a different base type, a lower voltage rating or a longer service life will have to source a separate product that matches those requirements.

Build & Daily Use

The clear glass envelope and intermediate screw base allow straightforward installation in compatible sockets without tools. Rated for 2500 hours of operation, the lamp will require periodic replacement in continuous-use applications, so keeping a spare on hand avoids unexpected downtime.

Questions about this item

How often will the 15 W T7 incandescent need replacing at its 2500-hour rated life?

At 2500 hours rated life the bulb lasts roughly 250 days if run ten hours daily, so plan on annual replacement under typical use.

What limit appears first when the 15 W 130 V lamp runs continuously?

The filament reaches its 2500-hour rated endurance before any other constraint, so lifetime is the primary limit under sustained operation.

How much heat and noise does the 95-lumen clear bulb produce all day?

Incandescent operation converts most of the 15 W into heat with virtually no audible noise, so expect warm surfaces and silent running.
