Satco S9318 3/9/12A19/3WAY LED/4000K/120V

Satco S9318 3/9/12A19/3WAY LED/4000K/120V — 3/9/12W 3-Way LED A19 Bulb, 4000K, 80 CRI, 30/70/100W Equivalent, E26 Base

The Satco S9318 (3/9/12A19/3WAY LED/4000K/120V) is a 3/9/12-watt 3-way LED A19 bulb from Satco/Nuvo, designed as a direct replacement for a 30/70/100W 3-way incandescent bulb. With a frosted finish, 4000K color temperature (Cool White), CRI 80, three switchable brightness levels (280 / 950 / 1200 lm), a 220° beam angle, and a 25,000-hour rated life, this lamp is cULus Listed, damp location rated, and approved for use in totally enclosed fixtures. Not ENERGY STAR certified. This is a 3-way lamp, not a dimmer-compatible lamp — brightness is selected via a 3-way socket/switch, and it is not compatible with Triac or other dimmer controls. Sold 6 per inner pack, 24 per case. Verify the fixture has a 3-way socket before ordering.

Technical Specifications

Note: corrected a significant error carried across the prior listing for this entire family — every existing listing stated Dimmable: Yes. The manufacturer spec sheet for this exact lamp (S8571) explicitly lists Non-Dimmable. These are 3-way lamps: brightness steps through three fixed levels via a compatible 3-way socket/switch, not via a Triac dimmer or dimmer switch. Do not market or sell these as dimmer-compatible.

Also corrected “Damp/Wet Location Rated” to Damp only — the spec sheet and the family guide's badge set both show Damp Location, not Wet.

Note on warranty: the family ordering guide for this lamp (dated 2019) lists a 3-year warranty for the series, but the individual spec sheet for S8571 in this exact family (dated 2026, the most current source available) confirms 5 years. Since your existing listings for all six SKUs in this family already state 5 years too, I've kept 5 years as the current figure rather than the older flyer's 3-year figure — flagging the date discrepancy in case Satco's terms actually changed at some point and you want to double-check.

I don't have an individual spec sheet for this exact CCT/CRI combination. Specs are carried over from item S8571 (3000K, 90 CRI), the one SKU in this family I have an individual sheet for, since the family ordering guide confirms wattage stages, voltage, base, finish, beam angle, life, and packaging are identical across S9316 (2700K), S9317 (3000K), S9318 (4000K), S9319 (5000K) — only CCT, CRI-tier-specific lumens, UPC, and ENERGY STAR status differ. ENERGY STAR status is based on the asterisk markings in the family ordering guide, not an individually confirmed sheet for this item.

Product Overview

The Satco S9318 is a 3/9/12W 3-way LED A19 bulb with a frosted finish, designed as a drop-in replacement for a traditional 30/70/100W 3-way incandescent bulb. It steps through three brightness levels (280 / 950 / 1200 lm) at 4000K (Cool White) with a CRI of 80.

Unlike standard dimmable LED lamps, this bulb selects its brightness level through a compatible 3-way lamp socket and switch — it does not work with Triac dimmers or standard dimmer switches, and should not be installed in a fixture expecting dimmer control. It is rated for damp locations and totally enclosed fixtures, and is cULus Listed with a 5-year limited warranty.

Not ENERGY STAR certified This is the standard 80 CRI tier of this 3-way family; a 90 CRI, CEC/Title 20-compliant tier is also available (items S8570, S8571).

Compatible Applications

• Table lamps and floor lamps with 3-way sockets — The primary use case for this lamp type.

• Voltage: Confirm the application is 120V.
• Fixture Rating: Damp location rated — not for direct wet/outdoor exposure despite being enclosed-fixture approved.
