LED Bulbs: Choosing the Right Cap Type and Output

The lamp cap type is the connector between the bulb and the fitting. The most common UK residential cap types are E27 (large Edison screw, used in pendants, table lamps and floor lamps), B22 (bayonet cap, standard in many traditional UK ceiling fittings and table lamps), E14 (small Edison screw, used in chandeliers, candelabra fittings and smaller decorative lamps), GU10 (two-pin twist-lock, standard for recessed spotlights and surface spotlights), and G9 (two-pin push-fit, used in wall lights, smaller ceiling fittings and some pendants).

Lumination stocks LED bulbs from Lampfix and Magnalux in all of these cap types. Both are specialist UK lighting component suppliers. Browse by cap type: E27 LED, B22 LED, E14 LED, GU10 LED, G9 LED, G4 LED.

Lumen Output: Replacing the Wattage Guide

When LED bulbs replaced incandescent and halogen sources, the wattage-to-brightness relationship changed fundamentally. A 60 W incandescent bulb produces approximately 800 lumens. An LED equivalent produces the same 800 lumens at 8 to 10 W. A 50 W halogen GU10 produces approximately 400 lumens; an LED GU10 equivalent produces the same at 4 to 5 W. Use lumens (not watts) to compare bulb brightness. Lumination lists lumen output for all LED bulbs in this range and the team can advise on the correct output for any specific fitting or room.

Dimmable LED Bulbs: Compatibility Considerations

For LED bulbs to dim correctly on a dimmer circuit, both the LED bulb and the dimmer switch must be compatible. LED dimmable bulbs require a trailing-edge (electronic) dimmer switch, not an older leading-edge (resistive) type. Always check the minimum load of the dimmer against the total wattage of all LED bulbs on the circuit. Lumination stocks dimmable LED bulbs from Lampfix and Magnalux and the team can advise on dimmer switch compatibility for any specific bulb and circuit.

Frequently Asked Questions

The most common LED bulb cap types in UK residential lighting are E27 (large Edison screw), B22 (bayonet cap), E14 (small Edison screw), GU10 (two-pin twist-lock), and G9 (two-pin push-fit capsule). E27 and B22 are the two most common UK cap types in pendants, ceiling lights and table lamps. GU10 is the standard for spotlights and recessed downlights. E14 is used in chandeliers and candelabra fittings. G9 is used in wall lights, smaller ceiling fittings and some pendants. Less common types include G4 (miniature low-voltage capsule), GX53 (flat cabinet lamp) and R7 linear (used in older floor uplighters and security lights). Lumination stocks LED bulbs in all of these cap types from Lampfix and Magnalux. Free delivery applies to all bulb orders over £75.
To choose the correct LED replacement bulb, you need three pieces of information from the existing bulb or fitting: the cap type, the wattage (to calculate the equivalent lumen output needed) and whether the circuit has a dimmer. The cap type is stamped on the base of the existing bulb. The lumen output of the LED replacement should match the incandescent equivalent: a 60 W incandescent needs an LED of 800 lumens, a 40 W incandescent needs 450 lumens, a 50 W halogen GU10 needs 400 lumens. If the fitting is on a dimmer circuit, the replacement bulb must be explicitly marked as dimmable. Lumination lists all three specifications for every LED bulb in the range and the team at the Taunton showroom can confirm the correct replacement for any specific fitting.
For living rooms and bedrooms, 2,700 K warm white is the standard recommendation. It produces the relaxed, residential quality that most UK homeowners associate with comfortable evening light and matches the expected interior temperature of traditional British interiors. For kitchens, bathrooms and home offices where visual clarity and colour accuracy are more important, 3,000 K to 4,000 K neutral white is preferable. At 3,000 K the light is warm-neutral and still flattering. At 4,000 K it is a clean bright white suited to task areas. Avoid very warm 2,200 K decorative filament temperatures for task areas and avoid very cool 5,000 K to 6,500 K daylight spectrum for living rooms and bedrooms. Lumination lists colour temperature on every LED bulb in the range. With 1,797 or more Google reviews at 4.8 stars, customers trust these specifications.
No. Only LED bulbs explicitly marked as dimmable are compatible with dimmer switches. Non-dimmable LED bulbs on a dimmer circuit will typically flicker, hum or fail to dim smoothly, and in some cases may be damaged. Dimmable LED bulbs are available in all standard cap types from Lampfix and Magnalux through Lumination. The percentage of LED bulbs available in dimmable versions has increased significantly in recent years and most commonly used cap types (E27, B22, E14, GU10, G9) are available in dimmable formats. Always check the dimmer switch compatibility: dimmable LED bulbs require a trailing-edge (electronic or capacitive) dimmer switch, not an older leading-edge (resistive) type designed for halogen. Lumination stocks LED-compatible trailing-edge dimmers from Magnalux alongside the dimmable bulb range.
