Acuity Brands Lighting FAQ: Controls, Track Lighting Catalogs, Downlight OEM & Spotlights

I coordinate rush lighting orders for contractors and distributors—not the catalog marketing side. When a fixture spec is wrong, or the client suddenly needs a replacement in less time than normal lead times, I’m the one who makes the calls. These are the Acuity Brands questions I get most often when a deadline is already close.

What does Acuity Brands lighting actually cover?

Acuity is not one product line. It’s a parent company with a familiar set of lighting and controls brands underneath it. If you have specified Lithonia downlights, Juno track heads, Gotham or Mark accent fixtures, Peerless linear, or Sensor Switch occupancy sensors, you’ve already used Acuity products.

Why does this matter? Because Acuity Brands lighting comes in many forms: recessed downlights, track lighting, spotlights, lighting controls, photocontrols, OEM/private-label production, and replacement LED modules. A contractor who orders by parent company name will get the wrong catalog number. I ask for the family line and exact product number first.

Which Acuity Brands lighting controls should I specify?

Start with the behavior you need, not with the platform name. If the application only needs dusk/dawn control or daylight response, Acuity’s Dark to Light photocontrol line is the direct answer. For occupancy sensing, schedules, daylight dimming, or demand response, the fixture driver and control network have to match. I see nLight and Sensor Switch most often on commercial jobs.

The mistake is choosing the control before checking the fixture specification. The spec sheet will say whether the fixture is compatible with nLight, 0-10V dimming, or a standalone sensor. Not every fixture is nLight ready. It sounds basic, but it is the reason orders get stopped at the warehouse.

Where do I find the current Acuity track lighting catalog?

For commercial track and accent lighting, start with the Juno family within Acuity. Juno has its own track sections and product filters. If you hand me a printed catalog that is two years old, I will still check the current product spec online before entering an order.

As of spring 2025, the useful way to search is by rail type, voltage, fixture type, and trim family. The filters are better than a static PDF cover-to-cover because they show what actually fits the track today. If the product has changed drivers or trim, the online part number is the source of truth.

One caution: track head photos do not update every time the LED board changes. Verify the photometric spec sheet before telling a client the exact beam will match adjacent fixtures.

Can I get Acuity downlight OEM or private-label production?

Yes, Acuity supports OEM and private-label programs for distributors, electrical manufacturers, and other businesses that need fixtures with their own branding. This is not a public website order though. It’s a conversation with the OEM side of the business. Expect to answer questions about housing type, driver brand and dimming, CCT, UL classification, labels, packaging, and minimum volumes.

An OEM downlight program is built to repeat, not to rescue one deadline. I still kick myself for a March 2024 request: a distributor called 36 hours before an event and asked if we could produce a private-label downlight for their new product line. The honest answer was no. We got standard Acuity units from stock and kept the project moving. That was the right call, but it was not an OEM process.

What should a spotlight specification guide include?

For a spotlight, the first numbers I look for are beam angle and field angle. One says where the center hot spot goes; the other says where the light cuts off. If the guide only shows wattage and lumens, it doesn’t yet describe the fixture.

Then I check the driver dimming range. “Dimmable” is a claim. “5% to 100%” is a specification. If a hotel corridor is designed for 5% at night and the driver stops at 20%, the whole night scene is wrong.

Finally, check CRI/R9 when color matters, the input voltage options, and the date on the spec sheet. A spotlight specification guide from before an LED board change can be misleading. If the sheet is not dated, ask for a current copy.

Why does the lighting quote turn out to be higher than the first number?

Because the first number was a fixture or a head, not the complete assembly. Drivers, sensors, emergency battery packs, crossbars, trim, and freight are separate lines in commercial lighting. A quote that shows every line is a sign that the vendor has done this before. A quote that hides the lines until later is a sign that you are about to have an uncomfortable change order.

I have learned to ask what is NOT included before I ask what the price is. To be fair, this is not unique to Acuity. It is true of every lighting quote. The transparent quote may look higher at first, but it usually ends up being the cheaper path. The vendor who lists all fees upfront, even if the total looks higher, usually costs less in the end.

When should I replace the downlight instead of ordering Acuity replacement parts?

If the housing is still in production and the driver or LED module is a listed service part, replacement parts are worth trying. If the housing is discontinued, or the existing trim looks different from adjacent fixtures, replacing the whole downlight usually costs less in labor and callbacks.

I remember a rush order where we ordered a compatible module and it was, or rather, it turned out to be a module for the previous housing generation. It fit mechanically but not electrically. The label on the old fixture told us the exact model, but we skipped one step and paid for it. Always verify the component part number against the current parts list.

How do I move an Acuity Brands lighting order when I’m already behind schedule?

My first question is not “what fixture?” It’s “what is the exact voltage, driver, control, and mounting?” Those details determine whether the catalog number is right. Fixing a wrong part takes longer than paying for expedite.

Then call a distributor or local sales rep. Portals say “usually ships in one day,” but that does not mean your exact fixture is in the branch. Ask three questions: Is the SKU in stock? If not, what alternate SKU with the same photometrics is available? And can the alternate work with the controls already approved?

I have made this decision in two hours before. Normally I would compare a spreadsheet of options. With a deadline, I went with whichever warehouse answered the phone, gave me the model number, and sent an email confirmation. The freight was not pretty. The job was on time.

That’s the habit that saves projects: verify the spec first, confirm the shipment in writing, and pay for speed after the order is right.
