Advantage of Channel Letters When Operating a Business in the Evening   If you are an owner of a business that operates during the evening hours then LED channel letters are an excellent way to draw attention to your business. Illuminated channel letters come both standard, reverse lit or halo channel letters. Channel letters are usually fabricated with aluminum instead of steel since it will not rust. For your standard channel letters the faces are either acrylic of polycarbonate with a vinyl overlay for more complex channel designs.   [caption id="attachment_676" align="alignnone" width="300"] Reverse Lit or Halo Channel Letter[/caption] [caption id="attachment_677" align="alignnone" width="300"] Standard Channel Letter[/caption]
