	FOR YOUR INFO. CU = Coefficient of Utilization - Ratio of the lumens actually received by a particular surface to the total lumens emitted by the luminous source. This is dependent on the type of lamp, type of lighting system and color of the room. DF= Depreciation Factor - It is the factor related cleanliness of the lamp including the room , replacement od lamp after recommended life, etc. CU = lumens received/lumens emitted by lightsource DF = illumination when everything is new/illumination under actual condition

	Hello PWSlack In lieu of the Topic Starter's explanation: Bello is the first name often used in Africa for a boy. BELLO may be a shortened version of BELLOW - Which is done by using all CAPITALS in a Post on a Forum. BELLO may be a mis-spelled version of "Below". I can understand the confusion, because I was konfuzed myself, not being a mind-reader either. Trust that assists.
