self luminace material

Hey folks,

I'm trying to render a room with multiple lamps in different brightnesses for a comparison.

In this example I have 12 LEDs with 151 lumen for each of them.
Do I have to choose 151 lumen in the self luminance section the material dialog if each of the 12 LEDs will be assigned to the same material or do I have to sum the lumens of the LEDs (=1814 lumen) ?

Which lumen settig is right?

Thanks and a merry Christmas

Oliver.

the lumens will be divided among each triangle.
if you modeled your LED so that each one is a single triangle, then you would use 151 lumens x 12 = 1812 lumens.
if each LED is a rectangle, that = 2 triangles each LED, so then it would be 3624 lumens.
