To choose correct quantity of LED lights, the first thing you should do is creating a focusing point in the room with a single light. However, if you need to have sufficient amount of illumination for lighting up the entire room, you need to have many lights. Different types of room have a different requirement, which also depends on the size of the room and the purpose of it. For example- a kitchen requires lot of light as compared to a living room which should have an environment which is relaxing.
The correct placement of LED lights:
Led light strips should always be spaced in evenly manner to create effect of ambient lighting. This helps in distributing the lights uniformly and also reduces shadow formation. You can get the correct placement of lights done by http://www.ledstripslight.co.uk/. They will not only give lights but also experts for fitting them.
Distance affecting the luminosity:
The space between each and every strip led lights depends on the fitting type and sizes. For example- fittings of the lightings which have a diameter of approx. 4 inches should have a minimum distance of 4 ft. in each and every direction. As the space is reduced between the fittings, the intensity of the lightings gets increased in that particular room. Also, the effect is softened when the space is increased. If you add more fittings, the reduced luminosity can be counterbalanced which is given by the LED lights which are smaller.
Adjusting the luminosity of the lights:
A dimmer switch can be mounted. With the help of this, you can easily adjust the LED lights brightness whenever you feel that it is needed. You should always keep one thing in mind that if you are planning to use of a LED which is dimmable, you need to upgrade to dimmer switches which have enough lower load.
