Sustaining Memberships include many new services and benefits that were not previously available. Under the old model, sustaining member categories were determined for each entity based on a company’s annual lighting revenues. Now, you have the flexibility to select the sustaining member category that best meets the needs for your organization and allows you to maximize the services and benefits provided by the IES.
