In a clear glass pendant, a clear globe ceiling light, or a chandelier with open arms, the amber glow of a 2300K bulb adds warmth and character that a cooler bulb cannot replicate. The teardrop (Edison) shape is the classic filament form — H14cm × Ø6.5cm, which fits comfortably in most E27 pendants and ceiling fittings. At 350lm and 4W, this bulb is suitable for accent and ambient lighting rather than task lighting — it is not a high-output bulb. Dimmable with a trailing edge dimmer switch; a standard leading edge dimmer may cause flickering. Rated for 20,000 hours. 220–240V only — not suitable for 110V circuits.\u003c\/p\u003e\n\u003cp style=\"font-size:15px;line-height:1.8;margin:0 0 28px 0;color:#121212;\"\u003eWorks best in fittings where the bulb is visible or partially visible — clear glass pendants, open chandeliers, exposed ceiling lights, and adjustable arm wall lights.

The visible filament runs the length of the tube, giving a linear glow that looks particularly good in exposed-bulb wall lights, adjustable arm lamps, and open chandeliers. Like the teardrop version, this bulb is 2300K — an amber, candlelight tone that is noticeably warmer than the standard 2700K warm white. At 350lm and 4W, it is suited to accent and ambient lighting rather than task lighting. Dimmable with a trailing edge dimmer switch; a standard leading edge dimmer may cause flickering.

line-height: 1.8; margin: 0 0 16px 0; color: #121212;\"\u003eThe 60° beam angle is the defining specification here. Where a standard 36° GU10 spot concentrates light onto a narrow area, this wide flood version spreads illumination across a broader ceiling plane — reducing dark patches between fittings in kitchens, hallways, and open-plan spaces. At 560lm from 5W, output is higher than a typical 5W GU10 spot (380–400lm), a result of the aluminium heat-sinking and ThermoTec thermal management built into the lamp body. The 1.5kV surge protection adds reliability in installations where power spikes are a concern. Colour temperature is fixed at 3000K — warm white, slightly cooler than 2700K, which suits kitchens, bathrooms, and workspaces where a clean neutral tone is preferred. Not dimmable: if a dimmer circuit is in place, use the dimmable GU10 variant instead.\u003c\/p\u003e\n\u003cp style=\"font-size: 15px; line-height: 1.8; margin: 0 0 36px 0; color: #121212;\"\u003eThis bulb works best in recessed downlights, surface-mounted spotlights, and track fittings where wide, even coverage is the priority.

At 4000K, the light is neutral — neither warm nor cold — with a clean, crisp quality that improves visual clarity and colour accuracy. This makes it the correct choice for task-heavy environments: kitchen worktops where food preparation requires accurate colour rendering, bathroom mirrors where grooming requires even shadow-free light, home offices where screen glare and eye fatigue are a concern, and commercial or retail spaces where product colours need to read accurately. In a living room or bedroom, 4000K will feel clinical compared to 2700K or 3000K — it is not the right choice for atmospheric or relaxation lighting. At 60° beam angle and 520lm, the output and spread suit general ceiling illumination rather than accent or spot work.

The cap type is identical (GU10 push-and-twist), so it fits the same fittings. The colour temperature will differ: most halogen GU10s run at 2700–3000K, so switching to 4000K will produce a noticeably cooler, crisper light.

The 4000K cool white tone is neutral and crisp — suited to kitchens, bathrooms, home offices, and task areas where visual clarity matters more than warm ambience. At 60° beam angle, light spreads broadly across the ceiling plane rather than spotting a single point, which reduces dark patches between fittings in multi-downlight circuits. Dimmable — compatible with LED trailing edge dimmers. Standard leading edge dimmers are not recommended and may cause flickering. If you are unsure what type of dimmer you have, check the switch plate: a trailing edge dimmer is usually labelled TE or LED.

If your existing fitting takes an SGU10 compact fluorescent, this 7W LED is the correct replacement: same base, same output level (650lm), a fraction of the running cost. At 3000K warm white, the tone is soft and relaxed — suited to living rooms, bedrooms, and hallways where a warm, comfortable light is preferred over a crisp neutral or cool white. The 90° wide beam distributes light broadly across the room rather than concentrating it in a spot, which makes it well suited to general ambient lighting rather than task or accent use. Not dimmable — output is fixed at one level. Rated 30,000 hours, which is longer than most standard LED GU10 bulbs (typically 25,000 hours).\u003c\/p\u003e\n\u003cp style=\"font-size: 15px; line-height: 1.8; margin: 0 0 36px 0; color: #121212;\"\u003eBefore ordering, confirm your existing bulb is marked SGU10 — not GU10.

The 6400K daylight tone is the coolest in the residential LED spectrum — a blue-white light that mimics natural daylight, maximising visual clarity and alertness. It is the correct choice for spaces where accurate colour rendering and sharp contrast matter: kitchen worktops, bathroom mirrors, home offices, art studios, and commercial environments where product colours need to read accurately under artificial light. In a living room or bedroom, 6400K will feel stark and clinical — it is not suited to atmospheric or relaxation lighting. For those spaces, 2700K or 3000K warm white is the appropriate choice. The 60° wide beam distributes light broadly across the ceiling plane, reducing dark patches between fittings in multi-downlight circuits. Not dimmable — output is fixed. ThermoTec™ heat management and EnFiniti™ lens technology deliver consistent output and low glare over the rated 25,000-hour life.

The 4000K cool white tone is neutral and clear: not as warm as 2700K or 3000K, not as clinical as 6400K daylight. It reads well in kitchens, bathrooms, utility rooms, and commercial areas where visual clarity matters more than atmosphere. The 90° wide beam distributes light very broadly — broader than a standard 60° flood — which suits open-plan spaces and rooms where even, shadow-free coverage across the full ceiling plane is the priority. Polycarbonate construction. Energy rating B — the higher wattage (7W vs 5W) accounts for the lower rating relative to A+ models; the trade-off is higher lumen output.

At 460lm from 5W, output is slightly lower than a standard 5W GU10 (typically 500–600lm) — a result of the extended barrel geometry. The 4000K cool white tone is neutral and clear, suited to kitchens, bathrooms, and task areas. Dimmable — use a trailing edge (LED-compatible) dimmer switch. Standard leading edge dimmers may cause flickering.
