Custom Incentives for LED Signage Retrofits

How to apply for Custom Incentives for Signage LED Retrofits

By Pete Couture, Director, LED Lighting Division

This post explains how to get utility rebates for "custom" illuminated sign LED lighting retrofit projects based on energy saved.


Many utilities have a process to apply for incentives for “custom projects” based on energy saved as opposed to a “prescriptive” rebate program which is typically based on a set dollar amount per fixture replaced with an approved unit (DLC or EnergyStar certified). Because there isn't a category in DLC or EnergyStar for signage, any signage project to retrofit energy efficient LEDs must fall within a custom project incentive program.

Here are few key items to be aware of when applying for a custom incentive:

1. Most utilities require a pre and post audit to confirm energy savings. This is typically not required to apply for a prescriptive rebate.

2. Detailed product information, similar to what is submitted by the fixture manufacturer to DLC or EnergyStar, is usually required by the utility. They want to confirm that the fixture performs to known standards, meets any safety requirements, has an adequate warranty and has a life expectancy that meets or exceeds other similar technologies. (Example of the ILT K2 Summit Series LED Sign Module data required can be found below.)

3. Installation instructions, design assistance and UL retrofit certification are all key items to confirm are available when selecting a supplier for your signage retrofit project. Because signage is inherently custom by nature, to insure a successful installation, the supplier must provide a high level of support which includes these items.

International Light Technologies has a LED Sign Module called K2 which works well for a wide range of signage applications. K2, along with it's associated retrofit Rail and Bracket system, enables an easy retrofit of most sign cabinets. ILT customer service also offers design and layout assistance to make your installation go smoothly.
