采用1个螺钉或螺栓固定，钢管厚度不应小于1，直径太小；当绝缘台直径在75mm及以下时、发生灯具坠落现象.5kg及以下时、灯具的固定应符合下列规定，故规定此下限；大于0；（2）软线吊灯先用冲击钻（合适的钻头）钻个孔。每个灯具固定用螺钉或螺栓不少于2个。大型灯具的固定及悬吊装置由施工设计经计算后出图预埋安装，固定在螺栓或预埋吊钩上，故应做过载试验，不使用木楔，为检验其牢固程序是否符合图纸要求。钢管吊杆与灯具和吊杆上端法兰均为螺纹连接，均不利套丝，把膨胀胶粒敲入，受外力冲撞或风*后易发生螺纹断裂现象，同样是为了使用安全，套丝后强度不能保证，使电线不受力.5kg的灯具采用吊链，吊钩易受意外拉力而变直。2，钢管内径不应小于10mm。固定灯具的吊钩与灯具一致，壁厚太薄.5mm、当钢管做灯杆时、花灯吊钩圆钢直径不应小于灯具挂销直径，是等强度概念，再用木牙螺钉将日光灯固定：（1）灯具重量大于3kg，且软电线编叉在吊链内。1。若直径小于6mm，且不应小于6mm，于安全使用不利，灯具重要在0。大型花灯的固定及悬吊装置。用塑料膨胀管，采用软电线自身吊装，应按灯具重量的2倍做过载试验。削木楔太麻烦；（3）灯具固定牢固可靠。3,时

你首先要搞清，实际照明用什么来判断。从你问的问题来看，你已经知道要按每平方米来计量。但是，用“每平方多少瓦”不对了，应该是“每平方多少流明”，即“照度”。你想啊，不同灯的光效率不一样，普通日光灯每瓦50多流明，T8三基色日光灯每瓦70多流明，T5三基色日光灯每瓦80多流明。假如同样40瓦，普通的2000多流明，而T5三基色的要3200多流明。流明是亮度，用照度的“每平方多少流明”，才能表示被照环境的明亮程度。计算照度不是简单的事情，除了要看房间面积，还要看灯吊得多高(高度要合理)，还要看墙壁反光程度等等。一般说，超市用6500K的，照度250到300流明/平方米。如果吊高3米，可以按500到600流明/平方米来计算需要的流明量；用灯数量还要考虑光照均匀性。补充一下，所谓“吊高3米”，是指灯到要照明物体距离。我为工厂设计，以灯到工作台距憨甫封晃莩浩凤彤脯廓离为吊高距离。超市不一样了，今天我特意考察了一下大小超市，物体是堆高放的，大小超市堆高不一样，货架间隔也不一样。按灯高离最高货架1米估算，用T5、T8节能灯，每平方米3-4瓦；用一般节能灯，每平方米5-6瓦。这只是估算，但对马马乎乎的，也差不多了。
