High-rise building obstruction lighting reference configuration
● Lighting on high-rise buildings and groups of buildings should make their outlines visible from all directions. Approximately 45 m horizontal spacing may be used as a reference. Lights should generally be installed at the top; installation height H is measured from level ground.
● When the building height is 45 m, install one low-intensity obstruction light at the top.
● For building heights ≥45 m and <105 m, install Type B medium-intensity lights at the top and low-intensity lights at 1/2 of the height.
● For building heights ≥105 m and <150 m, install Type A medium-intensity lights at the top and Type B medium-intensity or low-intensity lights at 1/2 of the height.
● For building heights ≥150 m, install Type A high-intensity lights at the top and Type B medium-intensity lights at intermediate levels spaced 75-105 m apart.

高层建筑类航空障碍灯配置参考方案
●高层建筑及建筑群设置的障碍灯应能从各个方位看到建筑物的轮廓，水平方向也可参考45米左右的间距设置障碍灯，一般建筑应在其顶部安装障碍灯，安装高度H从水平地面开始计算。
●当建筑高度45米时，顶部设置一盏低光强航空障碍灯。
●当建筑高度≥45米<105米时，顶部设置中光强B型障碍灯，在其高度1/2处设置低光强障碍灯。
●当建筑高度≥105米<150米时，顶部设置中光强A型障碍灯，在其高度1/2处设置中光强B型障碍灯或低光强障碍灯。
●当建筑高度≥150米时，顶端设置高光强A型航空障碍灯，在中间75-105米分层之间分别设置中光强B型航空障碍灯。
