What installation requirements are needed for E10 versus E14 cabochon lights?

The installation requirements for E10 and E14 cabochon lights differ primarily in the size of the mounting hole required and the specific hardware needed, though they share some common installation steps.

Reasoning:

The core difference stems from the physical size of the bulbs. E10 bulbs have a base diameter of 10mm, while E14 bulbs have a 14mm base. This size difference dictates the hole that must be drilled in the mounting material. For E10 cabochons, you need to drill a 14mm hole, whereas for E14 cabochons, you need a larger 20mm hole. Some sources also note a 16mm hole for E10 cabochons, but 14mm is the most consistently cited standard.

Common Installation Steps:

Despite the different hole sizes, the installation process is similar for both types. After drilling the appropriate holes, you push the lamp holders through from the back of the material. For both E10 and E14, the maximum thickness of the mounting material is generally 10mm. If the material is thicker, a 40mm diameter area must be rebated on the back to accommodate the lamp holder, leaving a thickness of 1-10mm. Finally, the cabochon base is screwed onto the lamp holder to secure it.

Hardware Compatibility:

It is crucial to ensure that all components are compatible. E10 and E14 bulbs are not interchangeable and require different lamp holders and bases. For example, an E14 cabochon base is only compatible with E14 fittings and is not compatible with E10 fittings. Similarly, specific socket adaptors are available for different base sizes.

Conclusion: To install E10 cabochon lights, drill a 14mm hole; for E14 cabochon lights, drill a 20mm hole. For both types, the mounting material should be no thicker than 10mm, and you must use the correct, non-interchangeable lamp holders and bases for each bulb size.
