The Dimmable G9 4.5W LED Capsule Bulb outstrips an incandescent’s performance in every way. From its energy-efficiency, to the environmental benefits, it’s never been a better time to make the switch.

Savings for You

This LED would be a perfect replacement for a 50W GU10 halogen. It emits the same 500 lumens of light, whilst using just 4.5W – less than 10%! This means it could save you over 90% of your energy, and therefore over 90% on your lighting bills. You could actually run ELEVEN of these bulbs, and they’d still use less energy than an incandescent equivalent!

Plus, the lifespan of an LED is incredible.  This bulb has a lifespan of approximately 50,000 hours – or, when used for eight hours a day, over 17 years! Compare this to an incandescent, with a lifespan of around 1,200 hours, and you can already see the chasm between the two.

What to Do

This bulb measures just 60mm in height, and 15mm in diameter, making it a tiny bulb that slots perfectly into smaller spaces. It has a complete 360˚ beam angle, so it’s great for general lighting purposes.  It can easily be retrofitted into your existing 220-240v light system. It also has a standard G9 fitting.

What Temperature?

You can choose between two different colour temperatures for this LED. The warm 3000k light gives off a warm, intimate glow, and is often better deployed in a living room or bedroom. A cool 6000k light is better in a kitchen or bathroom, as it gives off a clinical light that helps you to focus. Have a look at this video for some tips on how to utilise colour temperature.

These bulbs come with a comprehensive warranty that can be extended to five years! Manufactured by Mirrorstone, these LEDs also have a 14-day cancellation period, so if perhaps you’ve chosen the wrong colour temperature, you can return or exchange it.

It’s Dimmable, Too!

A common misconception is that LEDs cannot be dimmed. Well, they can, but a different dimmer switch may be needed. With a traditional leading edge dimmer, they tend to expect a minimum wattage of around 40W – when this bulb uses just 4.5W, it’s clear it won’t work.

That’s why you need a trailing edge dimmer – they are perfect for dimmable LEDs, and ensure maximum compatibility. Have a look at our guide to dimmable LEDs for some more information.

Some Alternatives

We have a couple of other options for you to have a look at, if you don’t need as much power. We have a Dimmable G9 LED Bulb, 3W – it offers 360 lumens, and is the equivalent to a 35W halogen. The G9 LED Bulb, 2W isn’t dimmable, but it offers the equivalent light of a 20W halogen, 100 lumens, whilst using just 2W!

Why not kit the whole house out in power-saving LEDs – have a look at our huge range of LED light bulbs.

Excellent light output and colour. I hope they last well.

Sylvia Downe

Searched high and low for some dimmable G9 capsules that gave off a decent light. These are excellent. Easy to use website and quick service - all you could ask for!


Brian Lord

Gives an excellent working light.

Graham Turner

Nice and bright. Super fast delivery. Obviously longevity not known yet.


I recommend

Peter Nicholson

Superb product. Received 2days after ordering and gives off the best light ever!!!!

George Gillespie



Perfect!! Arriving within 2 days on standard delivery I’ve used this company numerous times and they always deliver in quality & service

Alan Shaw

Was using Halogens in a 4 light unit and they ran very hot, These give a better light output and run cool with a combined wattage less than 1 of the Halogens. Very impressed with these.


Easy to Fit and give a good bright light.

Brian Marshall

Impressed with the service and the bulbs, just what I was looking for. A most successful transaction thanks.

Stephen Beckley

I wanted a brighter bulb than the ones that came with the light fitting, and these certainly are.


Compact and emits far more light than the halogen bulb it replaced. Quick delivery too.

Mark Shearman

Very bright, excellent colour. Shame one failed after only 4 hours, still awaiting response from company.

The bulb I ordered turned up in just a few days and works well and yes it does dim!

David Tinker

Solid product, nice glow for a living room.

Colin Wiles

Great bright lights and fantastic price



Easy to fit and brilliant and bright a great quality product tried a few other brands bought from Amazon and eBay these by Mirrorstone are better quality definitely would recommend.


Have now ordered 6 more


Really pleased with the quality of these bulbs. I spent a long time searching for suitable LED replacements for 40W G9 halogen bulbs. Many available G9 LEDs provide less lumens and/or have a frosted outer covering resulting in a loss of sparkle and duller light. These bulbs are an ideal replacement and are very easy to fit.

Chris Balmont

Very good service and price and more importantly the bulbs are really good. They dim well and are as bright as our old 40w halogen bulbs.

Graham Turner

Bought for a 5 light ceiling cluster. Really bright even though they are Warm White. Good price and quick delivery.


Items ordered delivered and fitted without problems. Wish I had made the upgrade to this bulb earlier.

Kevin Newson

Brilliant bulbs and lighting and very bright. couldn’t find cool white G9 bulbs anywhere other than here.

Graham O’Connell

Much easier to fit than the old halogens they replaced. A good light too.

Bryan Evans

Looks great, rapid service etc etc. But it's twice the size of the old style it replaces. My fault entirely, but it doesnt fit the lamp.

Vic Tomlisson

Exactly as expected. Bright and controllable
