Email us a picture or spec sheet of existing fixtures for potential retrofit. Upon confirmation, an LED retrofit system will be determined and quoted. We typically require a sample fixture to be shipped to us for design and fit. A new LED retrofit kit is designed, built and installed into the sample fixture for testing.

Once the fixture has passed testing, the sample fixture is shipped back to the customer with the new LED retrofit kit installed. Installation instructions are included. Per customer approval, remaining retrofit kits may be purchased, built and shipped. LED retrofit kits may be ordered in bulk or at the buyer’s discretion for inventory.

There is no additional fee for the design of retrofit kits. Shipping charges for sample return to the customer are paid by 1st Source Lighting. Samples are billed on a 90 day “try or buy” conditional invoice. Samples may be returned at the customer’s expense.
