GU4 Spotlight Bulbs
With pins spaced 4mm apart, the GU4 Spotlight bulb is ideal for installation in fixtures with little space, such as a floor lamp or a hood. Despite its small size, the GU4 Spotlight bulb can generate a light output of 184 to 350 lumens. This gives you the choice of both cosy atmospheric lighting and bright working light. Because bulbs with a GU4 socket operate on 12V, you will need a transformer. Of course, this may already be available in your current fixture.
The colour code is a combination of colour rendering (CRI) and light colour (Kelvin). The first number indicates the colour rendering (1 = very poor colour rendering, 9 = maximum colour fastness). The second and third number contains the light colour. Example: the colour code 830 consists of good colour rendering (8) and warm white light (3000K).
Every bulb or fixture has an energy efficiency class A to G. Energy label A is the most efficient and G the least. LED lighting is the most sustainable lighting technique. Even if a LED bulb is rated E or lower, they still save 70% of energy compared to conventional lighting with the same energy label. Why is it the same label then? To motivate LED brands to get even more durable.
