did some math.
took the upper 5 rows, least influenced by the tent door.
thats 40 measuring points.
So we get:
44.344 at 315W
44.344 divided by 40
3,51936
multiplied by the area (86x86cm inside)
3,51936 x 0,7396
=2,6029
gives us
2,60 µmol/w at 315W wall.
same calc for the 178W gave me 2,606, so about the same.
note,, i extra took my normal killawatt, which gives me the highest readings as the smart plugs tend to show slightly too low, only 290W vs 315W
note 2, this lamps potentiometer isnt hitting 100k, as it doenst matter for me, i havent checked how much K.
Edit... when i doubble i should take the middle...
so i too kthe first 4 rows and took them by 2 as the other side should be quite identicla.
35.131 divided by 32
1.097,84
divided by 315W
3,485
x by the area 0,7396m2
2,5776
so 2,58 µmol/w at 315W wall.
