I manage facility purchasing for a 90-person company. When I took over in 2020, lighting looked like the easiest category on my list: pick a fixture, order it, install it. Then a quote arrived without mounting hardware, and finance rejected part of the invoice. Since then, I've learned to ask what's not included before I ask the price. This FAQ covers the questions I actually get when people plan lighting projects: the Signify acquisition Cooper Lighting 2020 deal, Signify Cooper Lighting Solutions transitions, outdoor downlights, recessed can housings, and LED grow lights.
Quick answers:
- Signify acquired Cooper Lighting Solutions in 2020.
- Signify is the parent company; Philips remains a product brand.
- 'Downlight buiten' means 'outdoor downlight' in Dutch, but it won't tell you the wet rating.
- A 'downlight can' is the housing, not the whole fixture.
- The best LED grow light is the one with published PPFD data and locally available drivers.
1. Did Signify acquire Cooper Lighting Solutions in 2020?
Yes. Signify (formerly Philips Lighting) acquired Cooper Lighting Solutions from Eaton in 2020. If you're searching 'Signify acquisition Cooper Lighting 2020,' that's the deal you're seeing. What changed for buyers: product families like Halo, Metalux, and Corelite moved into Signify's portfolio, while many products kept the old Cooper brand names. That can create confusion in procurement systems. I still see purchase orders that list Eaton as the vendor because nobody updated the old supplier record.
The bigger issue is product continuity. A fixture you bought in 2018 may have been superseded, even if it looks identical in the catalog. As of January 2025, the safest move is to verify the current SKU and warranty channel at signify.com. Don't assume your distributor's automatic cross-reference is complete. Sometimes they need you to send a photo of the fixture label.
2. What does Signify Cooper Lighting Solutions mean for warranties and spare parts?
For me, the first concern was replacement drivers and emergency lighting parts. The good news is that most Cooper product lines did not disappear overnight. Halo downlights and Metalux troffers are still widely available. The less fun part is the transition between old Eaton part numbers and new Signify SKUs. Not every old part number maps neatly.
What I do now: before I order a replacement driver or ballast, I send the distributor a photo of the existing fixture label and the component. That has caught more compatibility problems than any part-number search. It takes five extra minutes, and it avoids the awkward 'we thought this was the right one' email.
Total cost matters more than the unit price. A replacement driver might be $45, but the labor to access it in a recessed ceiling can be $180 if there's no clearance. When product lines change, the fixture being listed doesn't guarantee the installation effort stays the same. I keep a running cost column for every project now: fixture, driver, labor, disposal, and one contingency line.
3. Is Signify the same as Philips Lighting?
Basically, yes. Signify used to be called Philips Lighting. The company changed its name in 2018, but Philips remains a product brand. That's why you'll see 'Philips LED' on fixtures and packaging, while Signify is the legal entity on the purchase order. For a buyer, this matters more than it looks: warranty registration, payment terms, and software access are under Signify, not under the old Philips Lighting name.
I mention this because it confuses internal stakeholders. They see 'Signify' on an invoice and ask why we're not buying Philips. The short answer: we are. Signify is the parent company; the Philips lighting product line still exists. If your organization has approved vendor lists, update the approved entity to Signify so accounts payable doesn't reject the invoice.
4. What does 'downlight buiten' mean?
Honestly, I'm not sure why 'downlight buiten' shows up so often for US-based buyers. My best guess is that Google sometimes picks up Dutch product pages, because 'buiten' means 'outside' or 'outdoor.' So a downlight buiten is an outdoor downlight.
The warning I'd add: don't order by that term alone. An outdoor downlight from a European datasheet might be IP-rated but not UL-listed for the wet, damp, or dry location required by your local building code. Check the actual listing before you spec it. I've had vendors describe a fixture as 'outdoor' when they really meant 'not indoor, but not fully weatherproof either.' If a datasheet doesn't say wet/damp/dry, ask.
5. What is a 'downlight can'?
A can is the metal housing installed above the ceiling in traditional recessed lighting. The fixture was the can, plus a separate trim and a lamp. In the LED world, 'downlight can' is often used to mean the whole recessed assembly, but technically the can is just the housing. When you search 'downlight can,' you're probably trying to figure out whether you can retrofit the old housing with an LED module.
Retrofit kits are a legitimate way to save money. But they're not generic. I assumed a 6-inch retrofit would fit any 6-inch can. Didn't verify. Turned out the spring clips didn't line up, and the trim sagged on one side. It was a small fix, but it turned into an extra labor trip. If you're starting from scratch, an integrated LED downlight is simpler: one unit, one warranty, no parts to mismatch.
Before any retrofit, ask three things: Is this kit listed for my specific can model? Can the driver be replaced from below the ceiling? Does the warranty cover a non-standard opening? The last one sounds overly cautious, but after the spring clip incident, I'm comfortable being annoying.
If you still have serviceable cans, a retrofit can be cheaper on materials. Just remember that labor, disposal, and the accessibility of the driver are part of the total cost. The quote that only lists the fixture price isn't the full price.
6. What is the best LED grow light?
If you're hoping for a model number, I can't give you one—and I'd be suspicious of anyone who does without knowing your canopy size, hanging height, and target crops. 'Best' depends on PPFD (photosynthetic photon flux density), spectrum, driver quality, and whether replacement parts are available locally.
When we tested a small grow light for our office plant wall, the cheapest fixture had the highest wattage. The spec sheet didn't show a PPFD map. The numbers said it was enough; my gut said the missing map was a red flag. We went with a fixture that published PPFD data in micro-moles. It cost more, but the distributor stocked replacement drivers. That mattered when a different brand's driver delayed a colleague's project for six weeks.
For commercial grow operations, Signify's horticulture line publishes spectral data and supports lighting plans. Ask for a photometric plan for your exact room, not a generic crop chart. A good rep will want ceiling height, row spacing, and daily light integral targets. To be fair, a consumer-grade grow light can work for a small setup, but don't buy one for a commercial space without seeing the photometric map. The best LED grow light is the one whose claims you can verify before the PO.
