like a previous post.. we used a sun bulb many years ago...you can obtain it from some second hand store included socket.. we also had a distance about ½ a meter to the board
and it worked perfect..now I use flouresent tubes.. also from a face sun ,and I dont even have to change anything.it is just that now I need the tubes 10 cm from the board.
