I bought the white perspex with a thickness of 2mm that, according to the added specifications, did not let any light through. Well this is not true and causes me a lot of problems. The company that sold me this, has agreed with me and gave me back my money, but this doesn’t solve the problem…

Lighting up the words ‘Jij’ and ‘Vandaag’.
But the translucency of the material isn’t the only problem. We tried to make the display as thin as possible in order to increase the light intensity in each box. This assumption was correct. But we forgot that by reducing the scale, the influence of the imperfections would increase. So now we had 3 light leaks:

The solution is now to use aluminum foil and filler to close the gaps and reflect the light. Also the diffuser would be excluded.
