GU10 LED Bulb 3W — Choose 24° Narrow Spot or 120° Wide Beam, Warm or Cool White
A GU10 LED spotlight bulb available in two beam angles — 24° (narrow spot) and 120° (wide flood) — and two colour temperatures (warm white and cool white), for use in recessed downlights, track fittings, and surface-mounted GU10 spots. 3W, 250–499 lm, 50 000-hour rated lifespan, 220–240V. CE certified.

Beam Angle — The Decision That Determines Where the Light Goes
Beam angle is one of the most underestimated variables in downlight selection — and one of the most consequential. The same bulb, in the same fitting, at the same wattage, will produce a completely different result depending on whether it is a 24° or a 120° version. The 24° narrow spot concentrates all 250–499 lumens into a tight cone: the illuminated area on the floor or surface below is small and bright, with a sharp edge and high contrast between lit and unlit zones. This is the right choice for accent lighting — highlighting artwork, a shelf, a kitchen worktop section, or an architectural feature where you want a defined pool of light. The 120° wide flood spreads the same lumens across a much larger area: the light is softer, the edges are diffuse, and the overall effect is closer to general room illumination. This is the right choice for ceiling grids in living rooms, hallways, and bedrooms where you want even coverage without visible hotspots. Both variants are available in warm white (~2700–3000K) and cool white (~6000K) — the beam angle and colour temperature choices are independent of each other.
A common mistake is to use narrow-angle spots in a ceiling grid intended for general lighting — the result is a series of bright circles on the floor with dark zones between them, rather than even illumination. Conversely, using wide-angle floods for accent lighting produces a washed-out effect with no definition. Match the beam angle to the purpose: narrow for accent and task, wide for ambient and general. If you are replacing existing GU10 bulbs, check the beam angle printed on the current bulb before ordering.

Common Questions
How do I know which beam angle my current GU10 bulbs are?
+
The beam angle is usually printed on the base or side of the bulb, often as a number followed by a degree symbol (e.g. “24°” or “120°”). It may also appear on the original packaging. If you cannot find it, look at the lens on the front of the bulb: a narrow, deep lens typically indicates a spot angle (24°–36°); a wide, shallow or flat lens typically indicates a flood angle (90°–120°). If in doubt, the 120° version is the safer default for general room lighting.
Can I mix 24° and 120° bulbs in the same ceiling grid?
+
You can, but it requires deliberate planning. Mixing beam angles in the same grid without a clear purpose will produce uneven illumination — some areas brightly lit, others in shadow. A deliberate approach would be to use 120° bulbs for general ceiling coverage and 24° bulbs in specific positions aimed at a feature wall, a kitchen island, or a display shelf. Keep the colour temperature consistent across all bulbs in the same room to avoid a patchy appearance.
Is 3W bright enough for a kitchen or bathroom?
+
For a kitchen or bathroom used as a primary work or grooming space, 3W per fitting is on the lower end — particularly with the 120° wide beam, where the lumens are spread over a large area. In a grid of 6–8 downlights, the combined output will be adequate for general use. For task-critical areas (directly above a worktop or mirror), consider a higher-wattage GU10 or a 24° narrow spot that concentrates the available lumens onto the specific surface.
What is the illuminated area diameter for each beam angle at standard ceiling height?
+
At a standard ceiling height of 2.4m: a 24° beam produces an illuminated circle of approximately 1.0m in diameter on the floor. A 120° beam produces a circle of approximately 4.8m in diameter — effectively covering the entire floor area of a small room from a single fitting. These are approximate values; the actual spread depends on the specific optics of the bulb. Use these figures as a starting point for spacing calculations when planning a ceiling grid.
Will this bulb fit in a fire-rated downlight housing?
+
Yes — this is a standard GU10 bulb and will fit in any GU10 downlight housing, including fire-rated versions. The fire rating applies to the housing, not the bulb — the housing is designed to maintain the fire integrity of the ceiling regardless of which GU10 bulb is installed. Ensure the housing is rated for the wattage of the bulb (3W is well within the range of any standard GU10 housing). If you are installing in a new build or renovation, check that the housing carries the appropriate fire rating for your ceiling construction.
