Why divide the required lux with lumens from a bulb? lumens do not consider height and coverage. I am curious why not using the average lux measured at the same distance, provided by the light manufacture ?
Apologies I don't look at comments normally as these resources are for my students. Luminaires are all different depending on how they are built with diffusers etc, so I have not included this for simplicity and followed the formula with notional values. When I come around to upgrading this resource I will try to include this detail somewhere.
Hi there. Once you know the number of lamps you'd have to look at the ceiling layout and position them as equal distance as you can. This required length and area knowledge - I'll add this to my list of future posts but for now there are companies who do this for you - I found lightingcalculator.com through searching just now.

Apologies I don't look at comments normally as these resources are for my students. Lighting manufacturers provide their UF and MF depending on the fitting you choose. I'm not a published author and will not be able to reference everything due to time restrictions but when I come around to upgrading this resource I will ensure to add this detail.
Sorry to tell you this but on the area you are wrong the area you have ther is not 26msq but 170msq the area is times not plus 11.3x15m =169.5 thanks for trying kind regards

Why do you multiply 2 given areas? Dining room area=15sqm while living room area=11.3sqm, so more like 26sqm in total. Well not unless you were given the length and width of the room so you have to multiply to get the Area.

Really surpris9ng this doesn't ha e lots of like. Very apt and practically useful
Please how do we calculate the position of the lamps do that it gives equal spacing?

Is it possible to explain the method of calculating the utilization factor and maintenance factor?

Nice video , is the UF & MF fixed in doing calculation from where u get the values ,

It is dining room plus living room so around 26sqm.
