You can now find LED downlights in the market everywhere and these are both energy efficient as well as quiet friendly to the human eye.
The question that you would find yourself asking would usually be how many LED downlights do I need as there would be different varieties available in the market for providing you with different strengths of lighting which you may want to consider choosing from.
There is no simple and straightforward answer to how many LED downlights you would require as it would depend upon the size of your room as well as the type and model of LED downlight that you choose to go for.
If it is a small bedroom and you choose to go for a larger LED light then you would be able to find efficiency in even a single of it however if you have a larger room and you are going for smaller LED downlights then you would obviously require quite a few of these. The simplest answer would therefore be for you to try a few out and see if they provide you with sufficient lighting, if not then you can always go for additional ones.
