A big industrial Company consist a shop with a little luminance space, their company workman called it dark workshop. That building is equipped by a lot of filament lighting devices (app. 80 numbers lamp) but it hasn't enough luminance for normal activities.
A big industrial Company consist a shop with a little luminance space, their company workman called it dark workshop. That building is equipped by a lot of filament lighting devices (app. 80 numbers lamp) but it hasn't enough luminance for normal activities.
The rated power and voltage of mentioned lamps is 100W and 220 V respectively.
The company related authorizes decided to solve dark workshop problems after the time. According to one recommendation they replace mentioned lamp with similar type but twice rated power (200W and 220 V). In wonder they front any variation in building lighting condition.

How can you explain the reason of problem remaining?

ya 1st compare the lumens of the bulb and the allocation of the lamps also play an important role in lighting of the area..for example see the lamps arrangement at any jewelery stores ,with less power lamps they reflect more light and illuminate better..

What is your opinion about probably additional voltage drop due to load rising? According to figure below, in right hand of vertical red line which illustrate optimum source impedance ( resistance of interconnection cables equal to load impedance) the increasing of lamp number ( electrical loads) cause electrical output reduction or lamps illuminations.
