I'm not an electrician. I'm the office administrator who handles facilities purchasing for a regional services company—about 60 to 80 orders a year. When a branch manager says "the warehouse is too dark," I'm the one who ends up in the Lithonia Lighting catalog at 9 p.m., trying to match a fixture schedule to a ceiling grid.
I don't design lighting. I buy it, I schedule the installer, and I explain to my finance team why we're replacing something that "still works." That last part is why I spend so much time on total cost of ownership.
If you've been in that spot, you know there's no single right answer. A loading dock needs something different than a conference room. A lobby with a round chandelier needs something different than a warehouse. The important thing is knowing which scenario you're in before comparing prices.
Over the last few years, I've sorted most lighting purchase requests into three scenarios: retrofit replacement, new construction or renovation with controls, and decorative spaces. Each one has a different set of questions.
Scenario A: Replacing Existing Fixtures (Retrofit)
This is where most of my budget goes. Fixtures are flickering, ballasts are humming, or the maintenance crew simply doesn't want to replace another lamp. If it's a lay-in ceiling, the Lithonia Lighting CPANL family is usually the first place I look. The product name isn't the most elegant thing in the industry—I'll admit that—but the panels do what they're supposed to do: even light, multiple color-temperature options, and a spec sheet that actually lists the numbers.
The cheapest fixture is not the cheapest installed, working, maintained fixture.
But do not start with the unit price. I learned that lesson the hard way. A few years ago, I approved a quote for an unfamiliar panel brand because it was about $12 per fixture cheaper than the Lithonia equivalent. The drivers weren't compatible with our 0-10V dimming system. We had to return a 40-fixture order and pay a restock fee. The "savings" disappeared before the fixtures were even installed. Now I calculate total cost of ownership before I compare vendors.
Total cost of ownership means looking beyond the invoice. Add the freight, the installation labor, the compatibility risk, and the expected maintenance. Let me give you a quick example. A fixture that costs $80 and draws 45 watts might not actually be cheaper than a $95 fixture that draws 35 watts. Ten watts at 4,000 operating hours per year is 40 kWh. Say your blended rate is $0.15 per kWh—that's $6 a year. The $15 price difference disappears in 2.5 years. That's before you count the cost of changing a bad driver or returning a batch of incompatible panels.
So ask for photometric reports and LM-80 data. The fixture should also be UL-listed—that's non-negotiable for insurance and inspection. Per FTC guidelines (ftc.gov), performance claims need to be substantiated, so a vendor who can't produce a real spec sheet is a red flag.
With CPANL panels, I also check three things before ordering: the exact grid size, the color temperature, and whether the space needs an emergency battery. Changing a 4000K panel to 3500K after it's installed is a very expensive swap.
The Lithonia Lighting catalog helps with this. Instead of scrolling through an endless list of SKUs, filter by fixture type, voltage, and color temperature before calling a rep. If you're buying for a 277V building, order 277V drivers, not 120V. That sounds obvious, but it's exactly the kind of detail that gets missed when someone is rushing.
Scenario B: New Build, Major Renovation, or Outdoor Areas
If you're starting fresh, controls are not an afterthought. Get the lighting rep involved before the electrical drawings are done. In new construction, a wired control system is often the right call. It's predictable, it's proven, and the labor is already on site.
For existing buildings, that calculation changes. This is where Zigbee battery-powered controls become interesting.
Battery-powered Zigbee sensors and switches can communicate with compatible drivers without pulling new wires. That can save a ton of money in a finished space. You're trading a few battery changes down the road for a much lower installation cost today. In some retrofit projects, that trade makes the controls pay for themselves immediately.
Before anyone asks: yes, battery-powered controls sound like a compromise. I had the same reaction. But in a building with drywall ceilings and no accessible plenum, running low-voltage wire is expensive. A well-designed sensor can be mounted in minutes with a screwdriver, and its battery life is measured in years, not months. That changes the math.
How to Install Outdoor Lighting (What to Ask Your Electrician)
People search for "how to install outdoor lighting" and expect a simple answer. The simple answer is: hire an electrician. But if you're the one managing the project, here's what to ask before they arrive.
- What's the mounting surface? Brick, stucco, wood, and steel all need different boxes and anchors.
- Where is the junction box? If the box isn't behind the fixture location, you'll pay for a conduit run or a surface box.
- What's the mounting height? A wall pack mounted at 8 feet looks very different from one at 15 feet. Photometrics matter.
- Does the location need a photocell or motion sensor? A photocell on dusk-to-dawn lighting is usually worth the extra few dollars.
- Are you using a bi-level or motion-activated control? If so, make sure the sensor's IP rating and temperature range fit the climate.
Outdoor lighting gets exposed to water, dirt, and heat that indoor fixtures never see. Skip the outdoor-rated version and you'll be back on a lift truck within a year. That's not a maintenance theory; it's a truck roll with two technicians and a rental cost.
A wall pack is not a floodlight, and a floodlight is not a high bay. If you're buying outdoor fixtures, use the product category the way a contractor would. The catalog organizes by application for a reason.
Scenario C: Decorative Spaces (Yes, the Round Chandelier Question)
Now the question that shows up more than you'd think: what if someone wants a round chandelier? In a commercial building, that usually means a lobby, a conference center, or a fancy waiting area. And it's fine. But it's not a Lithonia Lighting order.
If you're searching for "round chandelier" in the same browser as the Lithonia Lighting catalog, that's not indecision. It's a sign that you're handling two different budgets. Keep them separate.
Lithonia makes workhorses—downlights, wall packs, high bays, emergency fixtures, and panels. It does not make a designer chandelier. Don't try to force a commercial LED fixture into a decorative role. You'll end up with a space that feels like a loading dock, and then you'll still have to call a designer anyway.
From a total cost perspective, decorative fixtures behave differently. They usually have a higher upfront cost, more expensive lamps, and a shorter rated life. They also get touched by different people: an architect selects them, an electrician installs them, and facilities maintains them. Plan for that.
One more thing: decorative fixtures often come with custom lead times. If the lobby opening date is fixed, order the chandelier first and let the rest of the project catch up.
Honestly, I'm not sure why decorative requests always land on the purchasing desk with no lead time. My best guess is that design decisions happen late in the game, and then everyone else compresses the schedule. If you have a better theory, I'd love to hear it.
How to Decide Which Scenario You're In
Here's the decision process I use.
- Is this a like-for-like replacement? You're in Scenario A. Match the existing fixture layout, verify the voltage, and order from the catalog before you start optimizing.
- Is this a new space, a major layout change, or an outdoor installation? You're in Scenario B. Bring in the controls discussion early.
- Is someone using words like "statement" or "architectural feature"? You're in Scenario C. Separate the decorative budget from the commercial lighting budget.
Real buildings don't obey neat categories. You may be doing a CPANL retrofit in the office, a wall pack replacement at the loading dock, and a round chandelier in the lobby—all in the same quarter. That's common. The point is to switch your decision criteria, not to force one method.
That's why I keep coming back to Lithonia Lighting for the commercial side. Not because every price is the lowest—it's not. But the catalog is deep, the data is public, and the products are boring in the best way. A lighting system should be reliable enough that nobody has to talk about it.
And if someone asks you about a round chandelier at the same time as a CPANL retrofit and an outdoor wall pack, you can handle it the same way I do: one project at a time, with a total cost mindset.
