Thank you everyone. I love this forum :D

Update:

Sorry but I came across another problem. An LED light uses less Watt than the usual fluorescent lights so for example if I put the power consumption for a LED panel to be 45W then how would open studio know that, that is sufficient lighting ? I mean Open studio wont know that LED lights has a higher light efficacy. Would this be a problem in the model ?

Kind Regards, RMAK
