This Waco Illumination Holder is a standard electrical accessory designed to hold a light bulb with a B22 (Bayonet Cap) base and connect it to the electrical circuit. Bayonet cap holders are common in many regions due to their secure, twist-and-lock mechanism. The 5A / 250V rating ensures the holder can safely manage the electrical load for various bulb types up to a theoretical maximum power of 1250W ( or ), which is more than sufficient for modern energy-efficient lighting. Furthermore, its black colour is ideal for installations requiring a specific aesthetic, such as matching dark cables or mounting on dark ceilings.

B22 Illumination Holder Benefits and Features
- B22/Bayonet Cap Specific: Designed for the common B22 bulb base, offering a secure twist-and-lock connection.
- Standard Electrical Rating: The 5A / 250V specification is suitable for most domestic and commercial lighting circuits.
- Durable Construction: Typically made from robust, high-quality materials (like nylon or bakelite) for long-term reliability and safety.
- Black Colour: Provides a standard, neat, and unobtrusive finish for various lighting applications.
- Universal Frequency: Compatible with both 50Hz and 60Hz power systems.
Step to Follow For Wiring the B22 Illumination Holder
Preparation:
- Safety First: Firstly, ALWAYS turn off the electrical supply at the main circuit breaker before touching any wires or beginning installation.
- Cable Preparation: Subsequently, strip the ends of the power cable wires (Live, Neutral, and Earth, if applicable) to the appropriate length specified by the holder terminals.
- Gather Tools: Moreover, have a screwdriver (flat-head and/or Phillips, depending on the terminal screws) and wire strippers ready.
How to Wire the B22 Illumination Holder:
- Separate Holder: To begin with, carefully dismantle the lamp holder body to expose the internal terminal block (this usually involves unscrewing the skirt or base).
- Connect Wires (Crucial Step): Then, connect the wires to the correct terminals:
- Live (L): Connect the Live wire (often Brown or Red) to the central terminal in the holder. In B22 holders, it is critical that the Live wire connects to the central contact/plunger.
- Neutral (N): Connect the Neutral wire (often Blue or Black) to the terminal that connects to the outer contact/plunger.
- Earth (E): If a metal lamp holder is used, connect the Earth wire (Green/Yellow) to the dedicated Earth terminal. For a fully plastic/nylon holder, no Earth connection is required on the holder itself, but the earth wire must be safely terminated nearby if present in the cable.
- Secure Screws: Furthermore, tighten the terminal screws firmly to ensure a secure electrical connection.
- Reassemble: Subsequently, reassemble the lamp holder body and ensure all parts are securely fastened.
- Test: Finally, switch the power back on and test the light with a compatible B22 bulb inserted.
Cleanup:
- Ensure all wiring off-cuts are safely disposed of.
- The holder requires no regular cleaning other than the occasional wipe down if it’s exposed.
A Few Scenarios Where the Product Can Be Used:
- As a batten holder (where the holder screws directly to the ceiling) for B22 bulbs in utility areas.
- In pendant light fittings, where a B22 bulb is suspended.
- To replace a damaged B22 lamp holder in any existing light fixture.

Health and Safety
Due to the risk of electric shock, installation must be performed with the power completely isolated. If you are not familiar with electrical wiring, consult a qualified electrician. Do not exceed the maximum current rating of 5 Amps or the maximum voltage of 250 Volts. Ensure the Live wire is connected to the central terminal for safety. Do not touch any exposed terminals while the power is on.
