SerBion Light Socket Outlet Adapter, 3 Prong Light Socket Adapter, Polarized Light Bulb Outlet Socket, to Plug Adapter for Garage Porch

I’m a sucker for simple fixes that save me from running new cable. The SerBion light socket adapter is exactly that kind of tool: screw it into an existing E26/E27 lamp holder and you suddenly have a pass‑through bulb socket plus two outlets on the sides. In spaces like garages, attics, closets, and sheds where a light socket is all you’ve got, this little adapter can be the difference between “not possible” and “plug it in right now.”

What it is and why it’s useful

This is a compact adapter that converts a standard Edison socket into a small power hub: a bottom E26 socket for your bulb and two side outlets for accessories. On my unit, one side is a grounded 3‑prong receptacle and the other is a polarized 2‑prong. That layout covers most low‑power devices I’d want to run near a light fixture—think cameras, Wi‑Fi extenders, small chargers, or LED shop lights—while still keeping a lamp in play.

SerBion rates the adapter at 1250 W/10 A total, with the bulb socket limited to 60 W. The housing is flame‑retardant PBT with brass contacts, and it includes over‑temperature, over‑current, short‑circuit, and over‑voltage protection. It’s a tidy package that aims to do a specific job: add a couple of outlets without opening a wall.

Setup and first impressions

Installation is straightforward: cut power, remove the bulb, screw the adapter into the socket, add your bulb back, and plug in your device. The threads on my sample engaged cleanly, and the adapter seated flush in both a porcelain keyless lampholder and a metal fixture with a shade removed.

The body is lightweight plastic, but it doesn’t feel flimsy. The receptacles have a firm grip on plugs—strong enough to inspire confidence, but not so tight that you’re fighting gravity on a ceiling fixture. The overall diameter (about 3.8 inches) is wider than a bare bulb base, so if your fixture has a tight decorative shade or a narrow opening, check clearance before committing.

One important note: there’s no pull chain or on‑device switch. If your fixture is controlled by a wall switch, that switch controls power to both the bulb and the outlets. If you need the outlets to be live all the time, install the adapter in a socket that’s on constant power.

In use: where it shines

I used the adapter in three scenarios:

• Garage ceiling socket powering an LED bulb, a small USB charger for a battery inflator, and a Wi‑Fi access point.
• Attic lampholder feeding a low‑wattage LED bulb and a compact humidity sensor.
• Workshop utility light socket driving an LED bulb and a plug‑in LED shop light.

In each case, the adapter stayed cool to the touch under light loads. With two low‑draw devices and a 9 W LED bulb, I measured only a slight warmth at the body after an hour—nothing I’d call concerning. The bottom bulb socket’s 60 W limit sounds tight, but for LED or CFL bulbs it’s a non‑issue. If you’re still using a 60 W incandescent, stick to the rating; better yet, swap to LED and give yourself more overhead.

The side outlets are placed opposite each other, and orientation matters. If you want the outlets facing a particular direction, thread the adapter in until snug, then back off slightly to line it up. Do this with power off and make sure there’s still good contact; don’t leave it loose enough to wobble. Overhead plugging can be awkward on a ladder—short, flexible cords help.

Safety, capacity, and the limits to respect

The 10 A/1250 W rating is generous for small electronics but not meant for heavy appliances. Avoid space heaters, large dehumidifiers, shop vacs, air compressors, or anything with a substantial motor. Surge protection isn’t part of the package; if you’re plugging in sensitive electronics, add a small surge protector downstream—but still honor the 10 A total limit.

A point many people miss: a 3‑prong receptacle implies a safety ground, but a standard Edison lamp socket doesn’t provide a dedicated grounding path. Treat the 3‑prong outlet here as a convenience receptacle, not a guaranteed equipment ground. I don’t use it for tools or devices that explicitly require a grounded outlet; I keep it to double‑insulated chargers, camera power supplies, and LED lights. If your application truly needs a grounded receptacle, install a proper outlet on a grounded circuit.

This adapter isn’t weatherproof and isn’t intended for damp locations. If you’re using it outdoors, it needs to live in a covered fixture with a proper weatherproof shade and gasket. Even then, I keep it to dry, protected areas.

Build quality and durability

The PBT housing is a good choice for heat resistance, and brass contacts are standard fare for decent conductivity. Under normal loads, I didn’t notice discoloration, softening, or play developing at the joints. The contact points for the bulb are solid and didn’t flicker when I lightly tapped the fixture.

It’s not industrial‑grade—if you expect frequent plug/unplug cycles on a daily basis, you’ll put more wear on it than it’s designed for. Use it as a set‑and‑forget adapter, not a quick‑change outlet.

Fit and compatibility notes

• Shade clearance: The 3.8‑inch diameter can interfere with tight shades or domes. You may need to remove a shade or use a larger one.
• Plug clearance: Wide “brick” power supplies can block the other outlet; slimmer plug heads work best.
• Hanging weight: Avoid heavy transformers hanging from the adapter; use strain relief for cords if needed to prevent leverage on the socket.
• Switch control: Plan for whether you want switched or unswitched power. Smart bulbs or timers can help if you need the light on a schedule while keeping accessories powered.

What it’s great for

• Security cameras, smart doorbells (via plug‑in transformers), and Wi‑Fi extenders near a porch or entry—only in dry, covered fixtures.
• LED shop lights, work lights, and chargers in a garage or attic without outlets.
• Seasonal decor like string lights where you want a bulb and a plug at the same point.

What it’s not for

• High‑draw appliances and motor loads (heaters, vacuums, compressors, large dehumidifiers).
• Areas exposed to moisture or condensation.
• Applications requiring a code‑compliant grounded receptacle.

Pros and cons

Pros
- Adds two outlets plus a pass‑through bulb to any E26/E27 socket
- Simple installation and compact profile
- Reasonable 10 A total capacity for low‑power accessories
- Heat‑resistant housing with basic electronic protections
- Useful in spaces where running new wiring isn’t practical

Cons
- Outlets are controlled by the same switch as the bulb; no independent control
- Not weatherproof and not intended for damp locations
- Ground on the 3‑prong outlet isn’t a substitute for a properly grounded circuit
- Bulky wall‑wart plugs can block the second outlet
- Overhead plugging can be awkward in tight spaces

Bottom line

The SerBion light socket adapter does exactly what it promises: it turns a lonely light socket into a small, practical power hub without tools or rewiring. Used within its limits—low‑draw devices, dry locations, reasonable plug sizes—it’s a handy, inexpensive way to solve everyday power needs in basements, garages, attics, and sheds.

Recommendation: I recommend it for anyone who needs to power small, low‑wattage accessories where only a bulb socket exists and who understands the caveats about switching, load limits, and grounding. If you need a permanent, fully grounded, or outdoor‑rated solution, skip the shortcut and have a proper receptacle installed. For quick, safe, low‑power adds, this adapter is a smart, useful upgrade.
