回路数较少

根据规范《民用建筑电气设计规范》11.8.11：照明系统中的每一单相回路，不宜超过16A，灯具为单独回路数量不宜超过25个。大型建筑组合灯具每一单相回路不宜超过25A，光源数量不宜超过60个。建筑物轮廓灯每一单相回路不宜超过100个。

当灯具和插座混为一回路时，其中插座数量不宜超过5个(组)。

当插座为单独回路时，数量不宜超过10个(组)。

Well, you did not define the area of the conference room.

IESNA HANDBOOK has internation (North America ) regulation of average lux or footcandle for conference room. Circuit breaker per circuit(per phase) usually is 15AMP for 120V here at North America. Do not understand why 3rd floor tell you to use 25Amp per circuit ( per phase).

Also, you might consider color of Flurescent Lamp is too white and do not have enough red to give you good color tone on peoples’ skin.

特色作为design’s basic character is very important.

Dimming is also needed for conference room and flurescent dimming is not efficient as of today.

I, myself, usually will have PAR35 or PAR40 take care 60% and flurescent for the remaining 40%. A balance of power consumption and color usage.

再说了，怎么控制不是你说了算啊！它要达到什么装修效果就应该怎样控制的！！
