Eric, which white led's do you recommend for illuminating an 8" deep 4' x 8' D/F sign cabinet, with white poly faces? I will be sticking them to 1" aluminum square tubes that will be installed in the middle of the cabinet instead of fluorescent lamps. Please advise.
Sweet. Thanks Eric, Just so I am clear your referring to the spacing between modules correct? Will I be safe to space my square tubes at 12" on center? Or should i space at 10".
I was referring to space between square tube rows or columns. That's a pretty shallow cabinet for D/F, basically a little less than 4" from light source to face.
