Hello,
I would like to build a panel light with four flourescent tubes.
The tubes have a diameter of 26 mm and are 1200 mm long.
They have a distance of 42 mm one to another.
The tubes are mounted on a board, that is covered with aluminium foil as a reflector. Each tube produces a luminous flux of 2340 Lumen.
I would like to calculate the illuminance in Lux in one meter perpendicular distance of the panel light.
How can I do that ?
The result does not have to be perfect a result within 10 20 % of the actual value would be satisfactory.
