This G4 LED 15 SMD Disc is effectively a high powered LED that comes in a choice of 2 colours: Warm White (3000K) and Cool White (6000K).

It is a replacement for your existing G4 capsules and it uses only 2.1 watts of electricity while it delivers a light output to the equivalent of 20 watts halogen.

With such a small product delivering excellent qualities it gives 210 lumens of light output and has a beam angle of 180°.

This G4 LED Disc is non-dimmable and uses 90% less energy that its halogen counterparts, while it has a life expectancy of 30,000 hours.

Introducing SlimLED

The SlimLED range of light bulbs has had some great improvements.  Moving on from their old ways, these bulbs are slimmer, so they can fit into smaller fittings. They have been made much more energy-efficient, with a greater ratio of light produced to energy used than ever before. They also have longer lifespans, thanks to more effective heat sink technology.

Choose Between Two Colour Temperatures

Warm White is a colour that is highly recommended for use in a home which consists of areas such as bedrooms and hallways as well as living areas like living rooms and dining rooms. The colour itself is a yellowy one that gives you that feeling of warmth.

Opposite to warm white is Cool White which can be used in a modern environment suggested for use in businesses and public places. The colour gives you a sharper white hence it is used in big places where a more broader and bright light is needed.

Please refer to our LED colour guide to help you with your selection of colours.

They appear to be most suitable for a very specialist application I am using to provide light with less heat then what one expects from say miniature fluorescent tubes such that expensive materials adjacent to the light will not deteriorate over time. Although they are stated to be non-dimmable I have tested one with a lab power supply providing either constant current and/or constant voltage, and discovered that they do dim when approximately 9 volts is applied but there is only a small range of voltages around 9 that allows for this. For my own application the degree of reduction in light may be useful but I would not recommend reducing the voltage unless such a reduction could be tested in the long time i.e. over several years to ensure it does not result in any long term problems relating to their life expectancy,


Cheap as chips and dies the job :)


Very good lights - but delivery was dreadful. Took nearly 3 months...

The bulbs are perfect , but no details were sent about the dispatch time .

I've used this in an old camera that I've converted into a table/background light - it's perfect!! Really pleased with the outcome, happy with the price, delighted with the service.

I have been looking at ways of up grading the lights in my caravan. over the sink and cooker was a fluorescent light, after visiting a DIY store I purchased a set of three under cabinet lights with halogen bulbs. The bulb fitting was for 12 Volt halogens, I was also looking at using LED lights. having discovered the company on the internet I purchased 5 LED lights which would fit straight into the down lights. When I phoned in to place the order the person on the line was able to advise on what type would be the best. They arrived on the day promised and were soon fitted into the light fittings I had recently installed under the cabinets. I have not had the chance to use the caravan but they give off a good light, lighting up all of the surface. The advantage of LED's is that they consume less power which is helpful when on sites without mains hook-up, and the do not get hot which can reduce the risk of fire.

The product was delivered promptly and well packaged and I was very pleased with product quality. I was very impressed with the light output but unfortunately found that the diameter of the disc was too much for my light fittings, my fault not the discs or suppliers. I have to say I was gutted as I thought I had cracked getting great LED light in our motorhome at last. I am now going to test the customer service side and see if I can get a recommendation on my next best option :-)

Maurice Byrne

The LED lights were replacements for regular G4 bulbs they are now fitted in motorhome and things are looking much brighter lights were good value for money

Peter Coulston
