Your Building Upgraded to LED in 2020. Is It Time to Look at the Lights Again?

In 2020, replacing fluorescent lighting with LED was a smart investment. Many organizations reduced electricity use and maintenance almost immediately.

Six years later, those LEDs may still work perfectly well. But “we already have LED” no longer answers the whole efficiency question.

The question today is: Are your lights using only the energy your spaces actually need?

The difference between an LED upgrade and a smart lighting upgrade

A conventional LED retrofit reduces the power needed to produce light. Yet a fixture that stays at full brightness in an empty meeting room, a sunlit classroom or a quiet corridor can still waste electricity.

Modern lighting controls address that second opportunity. Depending on the space and system, they can dim lights when daylight is available, reduce output when an area is unoccupied, and adjust lighting to a schedule or the task at hand.

The DesignLights Consortium (DLC) reports that networked lighting controls have the potential to save 49% more lighting energy after an LED retrofit. That is a research estimate, not a promise for every building. Actual results depend on occupancy, daylight, operating hours, the existing fixtures and how the controls are programmed.

The performance benchmark has moved

The DLC maintains a Qualified Products List that helps buyers compare commercial lighting products. Its LED technical requirements have changed since 2020.

Under the DLC’s SSL Version 6.0, effective in 2026, minimum efficacy thresholds increased by a weighted average of 14% for Standard products and 12% for Premium products. Efficacy means light output per watt: how efficiently a fixture turns electricity into useful light.

The updated Premium criteria also put greater emphasis on controllability. A fixture with no integral control capability cannot qualify for the new Premium classification. These changes show how the industry’s expectations have advanced; they do not mean that every fixture installed in 2020 performs poorly.

There is another distinction: a product’s DLC listing and a building’s installed lighting are separate things. The DLC’s transition to Version 6.0 does not mean an older installed fixture suddenly stops working or must be replaced.

When is a second upgrade worth exploring?

Start by looking at what the building does today, not simply the year on the installation record:

• Do lights run at full output in spaces with changing occupancy?
• Are corridors, classrooms or common areas lit on a fixed schedule even when daylight is available?
• Can the existing fixtures accept useful controls, or would replacement make more sense?
• Are light levels appropriate for each space?
• What are the measured wattage, operating hours and maintenance costs?

Some organizations may get the best return by adding or improving controls on their existing LEDs. Others may benefit from replacing selected fixtures with more efficient, controllable models. An assessment can compare both paths before anyone commits to another retrofit.

At EcoBright Energy, we use DLC Premium Qplus products in our indoor lighting projects. Product selection matters, but so does the plan for where and when each fixture operates. The goal is to deliver the right light for the people using the space while avoiding energy use the building does not need.

If your organization upgraded to LED around 2020, that investment was a strong first step. Now may be a good time to measure what your lighting is doing today, and see whether it can do more.
