TCP LED GU10 Glass Spotlight Bulb, 345 Lumen, 2700K Warm White

This single TCP LED GU10 Glass Spotlight Bulb gives 345 lumens of 2700K warm white light from around 4.4W, roughly a 50W halogen equivalent, in a durable glass body with a 36° beam. It is a non-dimmable, twist-and-lock GU10 rated for 15,000 hours, perfect for replacing a single blown halogen or LED GU10 in a kitchen, hallway or living room spotlight.

• Durable glass outer body

What this bulb is best for

Sold as a single bulb, this is the easiest option when just one GU10 has blown in an existing fitting and you want to match a warm 2700K glow without buying a full pack. It suits kitchens, hallways, living rooms and any GU10 downlight or spotlight bar.

How to fit it

1. Turn off the power at the light switch (or isolate at the consumer unit if working on the fitting).
2. Let the old bulb cool fully before touching it.
3. Twist the old bulb anticlockwise a quarter turn and remove it from the GU10 fitting.
4. Line up the pins of this TCP GU10 bulb and twist clockwise until it clicks into place.
5. Restore the power and test the light. GU10 LEDs run directly on mains voltage, so no transformer or separate driver is required.

Frequently asked questions

Why is this bulb rated for 15,000 hours rather than 25,000?

TCP sells GU10 bulbs in a few build variants; this single-pack glass version carries a 15,000 hour rating, which still works out at roughly a decade of typical evening use, while other TCP packs in this range are rated up to 25,000 hours.

Can I mix this single bulb with our existing TCP pack-of-2 or pack-of-5 bulbs?

Yes, all of our 345 lumen, 2700K TCP GU10 bulbs share the same brightness and colour temperature, so this single bulb will match visually even if the rated life differs slightly between packs.

Is a glass-bodied GU10 bulb safe to use?

Yes, glass is a common, safe material for GU10 LED bulbs and handles heat well; just avoid touching the bulb while hot and fit it the same way as any standard GU10.

What does 345 lumens replace in old halogen terms?

345 lumens is designed as a close match for an old 50W halogen GU10, so this LED is a straightforward drop-in replacement.
