What this bulb is best for

345 lumens at 2700K is bright enough to properly light a living room, bedroom or hallway while keeping the warm, relaxed tone people expect from home lighting. It's a good choice where you want noticeably more brightness than a basic 250 lumen bulb but don't need a dimmer.

How to fit it

1. Turn off the power at the switch before you start.
2. If you're replacing an old bulb, let it cool down fully first.
3. Twist the old bulb anticlockwise a quarter turn and pull it free.
4. Push the new TCP GU10 bulb in and twist clockwise until it clicks into place.
5. Restore power at the switch.

GU10 bulbs run directly on mains voltage, so there's no transformer or separate driver to fit - it's a like-for-like swap in your existing fitting.

Frequently asked questions

Is this 345 lumen TCP bulb dimmable?

No, this particular bulb is the non-dimmable version. If you want to use it with a dimmer switch, choose our TCP 345 lumen 2700K dimmable glass bulb instead, linked below.

Is 345 lumens noticeably brighter than a 250 lumen bulb?

Yes - 345 lumens is around 40% more light output than a 250 lumen bulb, which is a worthwhile step up if a room has always felt a little dim.

Is a pack of 2 enough, or should I buy more?

A 2-pack suits a small fitting such as a pair of wall lights or a single small downlight run; for a full room of four or six spotlights, you'll likely want two or three packs.

How is this different from the glass version?

This bulb has a white-finished outer body rather than an exposed glass lens - the light output and colour are the same as our glass-bodied 345 lumen bulbs, it's simply a different look for the visible part of the bulb.
