GU10 LED Bulb 2700K — Narrow Spot, Warm White, Halogen Replacement
At 3.3W and 345lm, this bulb delivers the same output level as a standard halogen GU10 at a fraction of the running cost — rated A+ energy efficiency with a 15,000-hour life, which is approximately 12 times longer than an equivalent halogen. The 2700K warm white tone is soft and amber-leaning: the closest LED equivalent to the light quality of a traditional halogen, suited to living rooms, bedrooms, and dining areas where a relaxed, atmospheric light is the goal. The 36° narrow spot beam concentrates light precisely onto a defined area rather than spreading it broadly — the correct choice for accent lighting, display shelving, artwork, and directional downlights where a focused pool of light is needed. For general room illumination across multiple fittings, a 60° wide flood beam would give more even coverage. Not dimmable — output is fixed at one level. If a dimmer circuit is in place, this bulb will flicker or fail prematurely.
Push in, twist to lock, switch on — no electrician required for a like-for-like bulb replacement. Confirm the cap type is GU10 (push-and-twist, not GU5.3 or MR16) before ordering. Browse the full LED bulbs collection or read our indoor lighting guide.
Common questions
Is this a simple replacement, or does it need an electrician?
+
No electrician needed. This is a GU10 (push-and-twist) bulb — push in, twist to lock, switch on. If the fixture is already hardwired, replacing the bulb does not touch the circuit.
What is the difference between a 36° spot and a 60° wide flood GU10?
+
A 36° spot concentrates light onto a defined area — good for accent lighting, display shelving, artwork, and directional downlights where a focused pool of light is needed. A 60° wide flood spreads light broadly across the ceiling plane, reducing dark patches between fittings in multi-downlight circuits. For general room illumination, 60° is usually the better choice. For accent or directional work, 36° gives more control.
Can this be dimmed?
+
No — this bulb is non-dimmable. Fitting it on a dimmer circuit will cause flickering or premature failure. If you need dimming, browse our dimmable GU10 alternatives in the LED bulbs collection.
Is 2700K the right colour temperature for my space?
+
2700K is extra warm white — soft, amber-toned, and close to the light quality of a traditional halogen. It is the best choice for living rooms, bedrooms, and dining areas where a relaxed, atmospheric light is the goal. For kitchens, bathrooms, or task areas where a crisper, more neutral light is preferred, 3000K or 4000K would be more appropriate.
Is this a direct replacement for my existing halogen GU10?
+
Yes — this 3.3W LED is a direct replacement for a standard halogen GU10 in terms of lumen output (345lm) and cap type (GU10 push-and-twist). The main differences are energy consumption (3.3W vs typically 35–50W for halogen) and lifespan (15,000 hours vs approximately 2,000 hours for halogen). The 2700K colour temperature is the closest LED equivalent to the warm tone of a halogen bulb.
