Cooper Lighting Commercial Fixtures: A Buying Guide

Cooper Lighting is one of the most established names in North American commercial lighting, and also one of the most confusing to search for, because the company has changed owners. This guide clears up the naming, walks through the main product families and what each is built for, and gives you a short checklist for speccing Cooper fixtures on a commercial job.

Is it Eaton, Cooper, or Signify?

All three names attach to the same fixtures, which is why part numbers can be hard to track down. Here is the short version. Cooper Industries built the Halo and Metalux lighting brands over decades. Eaton acquired Cooper Industries in 2012 and ran the lighting business as part of Eaton. In October 2019, Signify (the company behind Philips lighting) agreed to buy that lighting business, and the deal closed on March 2, 2020.

So the fixtures are now made by Cooper Lighting Solutions, a Signify company, headquartered in Peachtree City, Georgia. If you see them listed under Eaton, that is the prior ownership. The brand names on the fixtures themselves, Halo, Metalux, Corelite, and the rest, have carried through every ownership change. When you spec a Metalux troffer today, you are speccing a Cooper Lighting Solutions product.

The main commercial brand families

Cooper Lighting Solutions sells under a wide portfolio. These are the families you are most likely to spec on commercial work:

• Metalux: the commercial workhorse. Troffers, flat panels, strip lights, and industrial fixtures for offices, schools, healthcare, and general interior spaces. If you are lighting a drop ceiling, Metalux is usually in the conversation.
• Halo: recessed downlights and housings, spanning commercial and residential. A default choice for downlight-heavy ceilings.
• Corelite: architectural linear and suspended fixtures for spaces where the fixture is part of the design, such as lobbies, open offices, and higher-end interiors.
• McGraw-Edison: outdoor area and site lighting, including pole-mounted fixtures for parking lots, campuses, and roadways.
• Lumark: outdoor and wall pack fixtures, a practical choice for building exteriors, security, and value-oriented site work.
• Sure-Lites: exit signs and emergency egress lighting.
• Greengate: lighting controls, including occupancy sensing and control systems.

Brands and catalogs change over time, so treat this as a map of where each family fits rather than a current parts list. Confirm the exact model and its specs on the product page before you order.

How to spec a Cooper fixture: the checklist

A buying guide is only useful if it helps you pick the right part. Run through these on every commercial job:

1. Match the family to the application first. Troffer or panel for a drop ceiling (Metalux), downlight for a hard ceiling (Halo), architectural linear for a design-forward space (Corelite), area light for a parking lot (McGraw-Edison), wall pack for a building exterior (Lumark). Getting the family right narrows the catalog fast.
2. Lumens before watts. LED fixtures are selected on delivered lumens for the space, not on wattage. Two fixtures at the same wattage can put out very different light. Check the delivered lumens and the efficacy (lumens per watt) on the cut sheet. Our guide on how to read a lighting spec sheet walks through the numbers that matter.
3. Set color temperature and CRI to the space. Offices and retail usually land at 3500K to 4000K, warehouses cooler, with CRI 80 or above (90+ where color accuracy matters). Many Cooper fixtures ship as CCT-selectable, which lets you match an existing building on site. See choosing color temperature for commercial spaces.
4. Confirm the controls path. Decide how the fixture dims before you buy: 0-10V, DALI, line-voltage, or an integrated control brand like Greengate. A fixture and its dimming method have to match.
5. Check mounting and voltage. Grid vs surface vs suspended, and 120-277V vs 347-480V for larger commercial services. These decide whether a fixture drops in or needs an accessory.
6. Verify the warranty and listings on the cut sheet. Look for the current warranty term, and the safety and performance listings (UL/ETL, DLC for rebate eligibility) on the specific model's documentation rather than assuming.

High-bay and warehouse work

For high-ceiling industrial and warehouse spaces, the selection criteria shift toward mounting height, delivered lumens, and distribution. That is its own topic; our LED high bay buying guide covers UFO vs linear and the specs that decide it, and Cooper's Metalux industrial line fits that category.
