Buying Guide: Choosing the Right E10 or E14 Bulb

Selecting the correct bulb for cabochon or signage lighting starts with identifying the cap type your system uses. Most cabochon and fairground installations rely on either E10 or E14 bulbs, both of which offer secure connections with lampholders and provide consistent illumination for decorative features. E10 bulbs are typically used for compact cabochons and tighter display layouts, while E14 bulbs offer a slightly larger format for bolder, more traditional fairground effects.

The choice between LED and incandescent bulbs depends on the aesthetic you want to achieve. LED bulbs deliver bright, efficient and long-lasting performance with minimal heat output. They are ideal for commercial displays or when low running costs and durability are priorities. Incandescent bulbs remain popular for installations requiring a classic warm look or vintage fairground feel, offering a softer glow that some designers prefer for heritage-style projects.

Bulbs in this category also come in clear, coloured and diffused finishes. Clear bulbs give strong, focused illumination and are commonly used inside cabochon lenses to highlight their shape and colour. Coloured bulbs produce vibrant, themed lighting and are often chosen for feature displays, while diffused bulbs help create softer, more even illumination in exposed fittings. Larger G45 bulbs, where included, provide a rounded decorative look for open installations and retro-styled displays.
