SlimLED 2.1W G4 LED 12 SMD Disc, 210 Lumens Description

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.
