Philips G4/GU4 LED Bulbs
The Philips LED G4 and GU4 LED have similar names, but are not the same kind and can therefore not be replaced by each other. The G4 LED is a capsule bulb that, due to its compact size, is very suitable for small fixtures. The pins of the G4 LED capsule bulb are around 0,65 and 0,75mm wide. The GU4 LED however is a LED spot that is suitable as accent lighting. The pins of the GU4 LED are around 0,65 en 1.05mm wide. What both lights have in common, is that they both bring the many advantages of LED lighting with them! For example, you save a significant amount of energy with both LED bulbs compared to their halogen counterparts and they both last much longer.
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.
