G9 led bulb

Lumination's G9 LED bulb range covers 2 W to 4 W outputs covering 200 to 400 lumens in dimmable and non-dimmable formats. Every bulb is listed with lumen output, colour temperature, beam angle and dimmability. Brands include Lampfix and Magnalux, both specialist UK lighting component suppliers.

G9 LED Bulbs: Specifications and Applications

G9 is a two-pin push-fit capsule used in wall lights, smaller ceiling fittings, some pendants and bathroom mirror lights. The most common applications are wall lights, smaller ceiling fittings, bathroom mirror lights and some pendant light fittings. When selecting a G9 LED replacement, confirm the lumen output required for the fitting and whether dimmability is needed. Lampfix and Magnalux supply G9 LED capsules in dimmable and non-dimmable formats at 2,700 K and 3,000 K.

Lumination stocks Lampfix and Magnalux LED bulbs across all cap types. Both brands are specialist UK lighting component suppliers chosen by Lumination's buying team for reliable lumen output, consistent colour temperature and confirmed dimmability on the appropriate variants.

Choosing the Right G9 LED Bulb

The key specifications to confirm when choosing a G9 LED bulb are: lumen output (the brightness, replacing the wattage guide of older incandescent bulbs), colour temperature (2,700 K for warm white, 3,000 K for warm-neutral, 4,000 K for neutral white), beam angle (where relevant for directional bulbs), and whether the bulb is dimmable. Dimmable G9 LED bulbs require a compatible trailing-edge dimmer. G9 bulbs fit into a ceramic holder and must not be touched with bare fingers during installation as skin oils can cause hot spots on the capsule glass.

LED Bulb Energy Savings Versus Halogen

LED G9 bulbs consume 80 to 90 percent less energy than equivalent halogen or incandescent bulbs for the same lumen output. A fitting previously using a 50 W halogen can run an LED equivalent at 5 to 7 W for the same light output. At the UK average electricity rate, a single fitting running 6 hours per day saves approximately £6 to £8 per year per lamp position. For a kitchen with 8 GU10 downlights or a chandelier with 10 E14 lamps, the annual saving across all positions is significant. Lumination lists wattage and lumen output for all LED bulbs so you can calculate the saving for your specific installation.

Frequently Asked Questions

A 4 W G9 LED capsule replaces a 40 W halogen G9 for equivalent lumen output. A 40 W halogen G9 produces approximately 400 to 500 lumens. A quality 4 W LED G9 from Lampfix delivers 350 to 400 lumens, which is the correct replacement range. This represents a 90 percent reduction in energy consumption for equivalent light output. For wall lights with multiple G9 holders (three or four holders in a single fitting), switching from 40 W halogen to 4 W LED per capsule reduces the combined power from 120 to 160 W to 12 to 16 W, a significant reduction at current UK electricity rates. Lumination lists the lumen output and colour temperature for all G9 LED options in the range so you can confirm the correct replacement before ordering. With 1,797 or more Google reviews at 4.8 stars, customers rely on Lumination for accurate bulb replacement specifications.

Most G9 LED capsule bulbs from quality suppliers including Lampfix are designed as direct dimensional replacements for halogen G9 capsules and will fit into existing G9 holders without modification. The pin spacing of G9 is standardised at 9 mm and all G9 LED capsules use the same spacing. However, some older or very compact wall light fittings have restricted space around the G9 holder that may not accommodate certain LED capsule body shapes. If replacing G9 halogen with LED in a compact fitting, check the body dimensions of the LED capsule against the available clearance in the fitting. Lumination lists the body dimensions of G9 LED capsules on the product page. If in doubt, the Taunton showroom team can advise on compatibility for specific fitting models before ordering.

G9 LED capsules fitted in bathroom-rated fittings (IP44 or IP65) are safe for bathroom zone use, as the fitting's IP rating protects the lamp holder and bulb from moisture. The G9 LED bulb itself does not require an IP rating as it is fully enclosed within the IP-rated fitting body. If you are replacing a G9 halogen bulb in a bathroom wall light or mirror light, the fitting must carry an appropriate IP rating for the bathroom zone (IP44 for Zone 2, IP65 for Zone 1). Never replace a bulb in a bathroom fitting without first confirming the IP rating of the fitting is appropriate for its position. Lumination lists IP ratings for all bathroom fittings that use G9 lamp holders. Free delivery applies to all G9 LED bulb orders over £75.

Dimmable G9 LED capsules are available from Lampfix and Magnalux. For G9 LED bulbs to dim on a dimmer circuit, both the bulb must be marked as dimmable and the dimmer switch must be a trailing-edge LED-compatible type. G9 LED circuits are often low wattage (4 to 16 W for a three to four lamp fitting), which can fall below the minimum load threshold of some dimmer switches. Confirm the minimum load rating of the dimmer switch before installing dimmable G9 LEDs. If the total wattage is below the dimmer minimum, flickering and premature failure of the bulbs or driver can result. Lumination's team can advise on the correct dimmer switch for specific G9 circuits and wattage totals. Magnalux supplies LED-compatible trailing-edge dimmers through Lumination alongside the dimmable G9 bulb range.

Lumination stocks G9 LED capsule bulbs from Lampfix and Magnalux. Lampfix supplies G9 LED capsules in 2 W and 4 W outputs in dimmable and non-dimmable formats at 2,700 K warm white and 3,000 K warm-neutral white, with body dimensions designed to fit standard G9 holders. Magnalux supplies G9 LED options with strong lumen output consistency across batch production, suited to applications where colour temperature uniformity across multiple wall lights or ceiling fittings is important. Both brands are selected by Lumination's buying team for confirmed lumen output and reliable dimmability. Lumination has been stocking G9 LED replacements since LED technology became viable for capsule lamp formats and the team at the Taunton showroom can confirm the correct specification for any G9 fitting.
