EMNOOTI 2-Pack E26 Light Socket Adapter - Converts Medium Screw Socket to Two Outlets With Pull Chain Switch - UL Listed, White

Why I reached for this socket adapter

In older basements and utility rooms, a single bare-bulb fixture is often the only power source. Rewiring for outlets is overkill for short-term needs, and multi-step adapters get messy fast. I tested the EMNOOTI socket adapter as a clean, quick way to turn one E26 lamp holder into two plug-in outlets while keeping the light. It’s a simple idea: screw the adapter into a standard medium base socket, plug in devices, and use the pull chain to switch just the bulb—no electrician required.

Design and build

The adapter arrives in a two-pack, finished in white so it visually blends with typical porcelain or thermoplastic lampholders. The body is urea resin, which is a hard, heat-resistant plastic commonly used in fixtures. It feels rigid rather than rubbery; I wouldn’t call it premium, but it doesn’t flex or creak.

Key details:
- Two 2-prong (ungrounded) AC outlets
- One E26 medium bulb socket on the front
- Pull chain that controls the bulb only
- UL Listed
- Ratings: outlets up to 660W at 125V; bulb socket up to 250W

The copper connector and aluminum screw threads seat cleanly in the lampholder. Contacts feel positive, and there’s no wobble once tightened into a standard fixture. Note that the outlets are two-prong only; you cannot insert a 3-prong grounded plug.

Installation and setup

Setup took less than a minute:
1. Turn off power to the fixture at the wall switch or breaker.
2. Remove the existing bulb.
3. Thread the adapter into the E26 socket and hand-tighten.
4. Reinstall a bulb into the adapter’s front-facing socket.
5. Restore power and test the pull chain.

In my tests, the adapter worked right away—no flicker, no arcing sound, and no loosening under normal bulb changes. The pull chain is short but standard. If your fixture is high or awkward to reach, add a bead-chain extension to make operation easier.

A few fitment notes:
- The adapter adds some depth to the fixture. If you’re using a shade or globe, make sure there’s enough clearance for both the adapter and a bulb.
- Because the outlets are on the body, plugs with large wall-wart transformers may crowd the bulb area. Using a short two-prong extension (sometimes called a “pigtail”) can help.

How the switching actually works

This is important for planning your setup:
- The pull chain controls only the light bulb in the adapter’s socket.
- The outlets are always on whenever the lampholder is energized.
- If the lampholder is controlled by a wall switch, turning the wall switch off kills both the bulb and the outlets. With the wall switch on, you can turn the bulb on and off via the pull chain while the outlets remain powered.

This model is great where you want the outlets powered but don’t want the bulb on all the time—think a basement camera, a plug-in shop light, or seasonal string lights.

Performance in everyday use

I tested the adapter with:
- A 9W LED bulb in the front socket
- A small LED shop light (about 30W)
- A USB power adapter for a Wi‑Fi camera

With all three running, the adapter body became slightly warm but never hot, and there was no buzzing. The pull chain has a definite snap to it—on the stiffer side out of the box. It didn’t misfire, but it’s not a silky feel. After a few dozen pulls, it loosened slightly while still giving a solid click.

Electrical behavior was stable. No visible dimming or flickering when a device was plugged into or unplugged from the outlets, and no unexpected trips at the breaker.

Safety, ratings, and limitations

This type of screw-in adapter can be a tidy solution, but it’s essential to respect the limits:
- Outlet rating: up to 660W at 125V total. That’s roughly 5.3 amps. Do not run high-draw appliances like space heaters, large dehumidifiers, or shop vacuums through this.
- Bulb rating: up to 250W. Incandescent bulbs near that rating run hot, and most modern fixtures don’t need that much light output. I stuck with LED bulbs under 15W.
- No grounding: The two-prong outlets are ungrounded. Only use devices that do not require a ground pin. Avoid tools and appliances with a 3-prong plug unless you are using appropriate, code-compliant measures elsewhere (in general, don’t defeat grounding).
- Environment: Best for dry locations. If you’re using this near a garage door or porch light, ensure the fixture is rated for damp or wet locations and use appropriately rated bulbs.

A UL listing is reassuring; it means the product design and construction have been evaluated to specific safety standards. Still, it’s not a license to overload or misuse. Keep loads modest and connections tidy.

Ergonomics and usability

• Pull chain feel: Slightly stiff but positive. If you struggle with short chains in high fixtures, add a longer bead-chain; it improves leverage and reduces the effort needed.
• Outlet accessibility: The two outlets make sense for low-profile plugs. If you’re plugging in two bulky bricks, plan on a short 2-prong splitter or pigtail to prevent crowding.
• Visual footprint: The adapter isn’t discreet, but in a basement, attic, or utility room it looks entirely at home.

Build quality and durability

The housing is rigid and seems appropriately heat-resistant. The threaded base and internal contact feel consistent when tightening into different lampholders. Over time, urea resin can be more brittle than some modern plastics, so I wouldn’t subject it to repeated drops or over-torque. Installed and left alone, it should hold up well. After a week of daily use with the pull chain, I noticed no loosening or slop.

Use cases where it shines

• Adding temporary outlets in basements, attics, or closets without running new cable
• Powering plug-in shop lights while keeping a bulb in the same fixture
• Feeding a small security camera or Wi‑Fi router in a utility space
• Seasonal lighting, like string lights in a garage or covered porch (observe damp-location requirements)
• Quick workaround while waiting for a permanent outlet installation

Cases where I wouldn’t use it

• High-wattage appliances (heaters, large dehumidifiers, air compressors)
• Any tool or appliance that requires a ground pin
• Enclosed fixtures with very tight clearances or poor ventilation
• Locations requiring tamper-resistant or GFCI-protected outlets

If you need a grounded outlet or GFCI protection, the right solution is to install a proper receptacle on a suitable circuit.

Practical tips

• Use LED bulbs to minimize heat and leave more headroom for the outlet load.
• Keep total outlet load well under 660W; I aim for 250–300W combined to be conservative.
• Add a chain extension for easier, gentler pulls.
• If your plug blocks the bulb, use a short two-prong extension to reposition it.
• Periodically check that the adapter remains snug in the socket.

The bottom line

The EMNOOTI socket adapter does exactly what it promises: it turns a standard lamp holder into a modest-capacity power hub with a controllable light. Build quality is solid for the category, the UL listing adds confidence, and installation is as easy as changing a bulb. The two big caveats are the lack of a ground (two-prong only) and the modest power rating—this is for light-duty loads, not shop heaters or heavy tools. The pull chain feels a bit stiff but reliable, and the form factor works well in open fixtures commonly found in basements and utility rooms.

Recommendation: I recommend this adapter for anyone who needs a fast, inexpensive way to add ungrounded outlets at a light socket for low-power gear—LED shop lights, small chargers, string lights, or a camera—while keeping bulb control at the fixture. If you require a grounded receptacle, higher power capacity, or code-compliant permanent outlets, skip this and install a proper receptacle instead.
