  How many tubes to put in a light box – help please?

  hi
  I know this has been answered before but I have been looking for the post for ages.
  I can only find this post http://www.uksignboards.com/post189469.html#p189469
  where ian says "general rule of thumb.
  space between tubes should be the same as the depth of light box,
  i.2 125mm deep lightbox have 125mm spacing between tubes."

  I have a light box that is 850mm high and the depth is 130mm so using that rule of thumb I would need 6 or 7 rows which seems an awful lot.

  I was planning on 4 rows initially before I read that.

  thanks phil

  Hi Phil.

  You should only need four maybe five rows.
  i was advised a long time ago and has worked well for me, to space tubes 6" – 8" apart and keep the rows that are closet to the edge of the box about 3" – 4" from there. This was based on a slightly deeper profile but if you keep to around the 6" mark you should be ok.
