Description

This G4 LED bulb is a compact bi-pin capsule designed to slot into low-voltage fittings in place of an older halogen capsule. It draws just 1.2W yet puts out 170 lumens at a clean 4000K cool white, with a wide 120 degree beam that spreads light evenly rather than concentrating it into a tight spot. American buyers will know the format as a G4 bi-pin lamp, a tiny two-pin capsule that runs on a 12V supply rather than direct mains. At only 20mm across and 31mm tall, it keeps a low profile inside enclosed and recessed fittings where space is tight.

Because it sits at a modest 170 lumens, this capsule suits accent and decorative duty rather than lighting a whole room. It works well in under-cabinet strips, display cabinets, cooker hoods, desk and reading fittings and the small multi-lamp fixtures that traditionally took G4 halogens. Several of these capsules grouped in a single fitting build up a useful pool of light, while one on its own gives a discreet, localised glow. The 4000K tone reads as a crisp neutral white that keeps surfaces and finishes looking true, which makes it a sensible choice for task corners and detail lighting where you want clarity without warmth.

The capsule runs on a 12V supply, either AC at 50Hz or DC, so it needs a matching low-voltage transformer or driver and does not connect to the mains directly. Colour rendering is rated at Ra 80, the cap is the standard G4 two-pin, and the body has a transparent finish. This bulb is non-dimmable, so it should be paired with a standard on or off circuit rather than a dimmer. Rated for around 20,000 hours and weighing only 2g, it is a long-life, low-energy swap for halogen capsules. We stock this G4 across a range of wattages and colour tones to match different fittings.

Frequently Asked

What fitting does this bulb need?

It has a G4 bi-pin cap, the small two-pin base used in low-voltage capsule fittings. The pins push straight into the holder, so check your existing lamp has the matching two-pin socket before ordering.

Does it need a transformer?

Yes. This is a low-voltage capsule that runs on a 12V supply, AC at 50Hz or DC, so it requires a suitable 12V transformer or LED driver. It will not work plugged straight into the mains.

What old halogen wattage does it replace?

At 1.2W and 170 lumens, it is a direct LED swap for the small 10W to 20W G4 halogen capsules once common in display and under-cabinet fittings. You get a similar light output for a fraction of the energy and a much longer life.

Is this bulb dimmable?

No, this G4 capsule is non-dimmable and should be used on a standard on or off circuit. Fitting it to a dimmer can cause flicker or shorten its life, so pair it with a plain switched supply.
