Installation 2: Channel Letters

Populating a channel letter with LED modules is as easy as peeling the liner off the factory-applied mounting tape and firmly pressing the light module in the desired location. It is important that the bonding surface be clean and dry.

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.
