The most common sizes of LED panels are 60x60cm (square) and 30x120cm (rectangular). These are standard sizes for almost all suspended ceilings. There are also various other dimensions available, such as 20x120cm or 15x150cm.
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).
This indicates which wattage of your old/conventional lighting is replaced by this LED product.
Unified Glare Rating
The Unified Glare Rating (UGR) indicates the extent to which the light of a product is blinding. This value differs per application and must comply with European standards (EN 12464-1). A low UGR value stands for a low glare factor. For offices and schools lighting with a UGR<19 value is mandatory and for public areas UGR<22.
Dimmable bulbs work in combination with a dimmer switch and allow you to determine the desired light output. Dimming also provides energy saving potential because less power is required when the lamp is producing less light.
