eRqILUJI 2 Pack, Light Socket to Plug Adapter, Convert Light Bulb Socket to Outlet Adapter (White).

A quick way to add power where only a bulb exists

I keep a couple of socket-to-outlet adapters in my kit for those odd spots that have a light fixture but no receptacle. This two-pack of white adapters from eRqILUJI has become my go-to for quick, low-power tasks—stringing patio LEDs, powering a small fan in a crawlspace, or plugging in a circuit tracer when I’m mapping a panel. They do one simple job: screw into a standard E26 light socket and present a grounded, three-prong outlet (also compatible with two-prong polarized plugs). Within that scope, they’re straightforward, sturdy, and surprisingly handy.

Design, build, and rating

The adapters are compact, all-white, and made from flame-retardant, heat-resistant plastic with copper conductors. The housing feels solid, the Edison threads are clean, and the outlet face has firm tension on the plug blades—no wiggle or sag with normal-sized plugs. The integrated one-piece body means there aren’t exposed seams or plates that flex, which is reassuring when you’re working above your head.

They’re rated for 125 V at 10 A (1,250 W). That rating matters. I treat these as a convenience outlet for light-duty loads: chargers, LED lighting, a Wi-Fi camera, a small box fan, or test equipment. Anything with heating elements or large motors—space heaters, hair dryers, air compressors, many shop vacs—is a no-go. Respecting the 10 A limit isn’t just about the adapter; it’s also about the lamp holder and the branch circuit you’re connecting to, which may not be intended for sustained high current.

Installation and fit

Using the adapter is about as easy as it gets:
- Turn off the switch or breaker to the fixture.
- Remove the bulb and inspect the socket for heat damage or looseness.
- Thread the adapter in by hand until it seats snugly—no need to overtighten.
- Restore power and plug in your device.

On a variety of fixtures—porch lampholders, a bare-bulb basement socket, and a ceiling lampholder in a closet—the fit was secure and the outlet aligned predictably. The small size helps in tight spots, but keep in mind that any plug you insert will add depth. In enclosed or decorative fixtures with tight shades, there may not be clearance for the adapter and a plug; I had to remove a glass globe on one porch fixture to use it. Also consider cord strain: a heavy cord hanging from a ceiling socket is not ideal. I prefer to use these where the cord can be supported or kept short.

Grounding reality check

The receptacle on the adapter accepts three-prong plugs. Whether that ground pin is actually bonded to a building ground depends on the fixture wiring. Many lampholders are two-wire only (hot and neutral) with no equipment grounding conductor. In metal fixtures with proper grounding, the ground path may be present; in older or plastic fixtures, it often isn’t.

I verified this using a simple outlet tester. On two fixtures, I saw a valid ground indication; on another, it reported an open ground. That’s not a fault of the adapter—it can’t create a ground where none exists—but it’s important to know. If your application requires a grounded connection, test the outlet first. When in doubt, use only double-insulated devices, a GFCI-protected extension cord, or relocate the device to a known grounded receptacle.

How it performed

I ran several practical tasks across a couple of weeks:

• Patio LED string lights: Plugged into a porch lampholder historically used for a single bulb. The adapter made it easy to power a multi-outlet extension with the lights and a small photo-sensor. Everything stayed cool to the touch, and the switch controlled the string lights as expected.
• Circuit tracing: Screwed the adapter into a ceiling lampholder, plugged in a tone generator/circuit tracer, and mapped the breaker quickly without needing an intermediate lamp-to-outlet dongle. Clean, simple setup.
• Small fan and phone charger: In a basement storage area, I used the adapter to run a 20-inch box fan on low and charge a phone. Combined load well under the 10 A limit. No audible buzzing, no warmth at the adapter body after an hour.
• Wi-Fi camera (5 V adapter): No issues, minimal wattage, and I appreciated being able to power the camera from a switched circuit for quick resets.

I intentionally avoided plugging in anything with a large inrush or high continuous draw. These adapters are not a substitute for a permanently installed receptacle; they’re a quick, low-power solution.

Safety and usage tips

• Respect the 10 A rating. Stay well under it for continuous loads.
• Avoid heat-producing appliances and large motors.
• Keep cords supported to prevent leverage on the socket.
• If using outdoors, keep the adapter and plug connections in a covered, dry location. This is not a weatherproof device.
• Use a receptacle tester to check for proper hot/neutral orientation and ground. Don’t assume a valid ground exists.
• Switch off the fixture before installation or removal.
• Inspect old lampholders for brittle insulation or looseness before trusting them with any load.

Where it shines

• Temporary or seasonal power: holiday lights, patio LEDs, event decor.
• Service tasks: powering test gear, charging a drill battery in a space with only a bulb socket, or running a camera temporarily.
• Rentals and quick fixes: adding a spot to charge a phone or run a small fan without modifying wiring.
• Attics, basements, closets, and sheds: lots of lampholders, few receptacles.

The two-pack format is convenient; I tend to leave one in a commonly used location and keep one in the toolbox.

What I’d change

• Orientation options: A rotatable outlet face or a right-angle variant would help with tight fixtures and cord routing.
• Indicator light: A small power-on indicator would be useful at a glance.
• Tamper-resistant shutters: Not essential for pro users, but a nice safety addition in households with kids.
• Clearer ground guidance: A note on verifying ground would prevent misuse and set expectations.

None of these are deal breakers, but they’d elevate the design and usability.

Alternatives and context

If you need a permanent, code-compliant receptacle, hire an electrician to add one to the circuit. There are also screw-in lampholders with built-in outlets and a bulb socket, but those add bulk and don’t solve grounding limitations. For outdoor or damp areas, a proper GFCI receptacle with an in-use cover remains the right long-term solution. This adapter is best viewed as a temporary or light-duty convenience, not infrastructure.

Verdict

The eRqILUJI socket adapter does exactly what I need it to do: turn an E26 lampholder into a useful, three-prong receptacle for low-power tasks with minimal fuss. Build quality is solid, installation is as simple as screwing in a bulb, and the compact size fits more fixtures than bulkier alternatives. The 10 A rating, variable grounding depending on the fixture, and lack of weatherproofing set clear boundaries—but within those, it performs reliably and safely.

Recommendation: I recommend this two-pack for homeowners, renters, and DIYers who occasionally need power where only a bulb exists. It’s an inexpensive, practical tool for temporary, light-duty loads—string lights, chargers, small fans, and test equipment—so long as you verify the circuit, respect the 10 A limit, and keep it dry. If your use case demands a permanent, grounded receptacle or high current, look elsewhere; for everything else, these earn a spot in the toolbox.
