The following guide can help determine where the LED modules should be places and how many to use. (Results may vary based upon desired light intensity and letter construction.)

• LED modules are designed to be placed in rows:
  • An LED module should have approximately 2.5 inches of space between modules within the row. This will result in 3 modules per linear foot.
• One row of LED modules will illuminate a stroke width of 4 inches or smaller in a channel letter (letter depth of 4 to 8 inches.) Letters with a stroke width larger than 4 inches should have multiple rows of LED modules placed according to the following rule:
• 4 to 6 inch stroke- 2 rows
• 6 to 8 inch stroke- 3 rows
• 8 to 10 inch stroke- 4 rows
• Actual number of rows/modules may vary depending upon the application. The above schedule is offered only as a guideline.

When all modules are in place, the secondary putput from the power supply can be connected. Multiple letters in a sign must be connected to the power supply in parallel. Use UL listed Insulation Displacement Connectors to make this connection and to cap off the open ends of the rows.

• All LED modules, regardless of color, operate on 12VDC.
  • All color modules can be connected to the same power supply.
  • Colors can be mixed on the same power supply.
