What is a GU10 bulb?
A GU10 bulb is a mains-voltage lamp with a twist-and-lock base, commonly used in spotlights and recessed fittings. The bulb is inserted into the socket and rotated slightly to lock it in place. GU10 bulbs are widely used in kitchens, bathrooms, hallways, and commercial spaces across the UK.
What is the highest wattage GU10 LED bulb?
Most GU10 LED bulbs range between 3W and 7W. Higher-wattage LED versions are uncommon because modern LEDs achieve high brightness with low power consumption. Instead of wattage, brightness should be compared using lumens, with brighter GU10 LEDs typically offering 400–500 lumens.
What are the best GU10 LED bulbs?
The best GU10 LED bulbs offer a combination of good lumen output, consistent colour temperature, and reliable build quality. Features such as dimmability, wide or narrow beam angle, and high colour rendering can also be important depending on the application. Choosing LED-rated fittings helps ensure long-term performance.
Why do my GU10 LED bulbs keep blowing?
If GU10 LED bulbs fail frequently, the cause is often an incompatible dimmer switch, voltage fluctuations, or poor heat dissipation within the fitting. Using LED-compatible dimmers and ensuring adequate airflow around the bulb can significantly improve lifespan.
How long should a GU10 LED bulb last?
High-quality GU10 LED bulbs typically last between 15,000 and 25,000 hours. Their lifespan depends on operating conditions, heat management, and driver quality. Compared to halogen GU10 bulbs, LED versions offer a much longer service life with reduced energy consumption.
