The following points need confirming when doing LED lighiting design for architecture :

1.The viewing direction

There are different views when looking at an architecture from various direction. So before doing the design, we should confirm a specific direction as its main view.

2.The distance

Make sure the average distance between people and the light. This will effect the clarity of facade and the lumen we put on.

3.The environment and background

If the environment is filled with high lumen objects, then we should dim the light we use.If the opposite, then brighten the light .

4.The atomsphere

Decide the atomsphere you wanna creat. According the light you choose, you can present vivid or plain , bright or dim.
