Ten years ago, I almost saved $900 on a contemporary chandelier for a hotel lobby. The cheaper fixture wasn't the same product. It was a lookalike with a generic, non-dimmable driver and a finish that peeled after six months. The $900 'saving' turned into a $2,400 redo, plus another round of expedited freight. That's when I started building a lighting procurement checklist.

I've managed commercial lighting procurement for six years, which means I've approved hundreds of purchase orders. I'm not an engineer or an electrician. I'm the person who signs the POs and owns the budget. This checklist is for anyone who buys lighting for commercial or hospitality projects: facility managers, hotel owners, restaurant operators, and electrical contractors. Use it when you're about to order new fixtures, replacement parts, or controls. There are six steps. Follow them in order, or jump to the one that's biting you today.

Step 1: Define the project condition, not just the product type

Before you write 'chandelier' or 'patio chandelier' in a PO, answer these questions:

  • Indoor or outdoor? If outdoor, is the location damp, wet, or coastal?
  • What is the mounting height? This affects lumen output, beam spread, and hanging length.
  • What controls are required? Dimming, photocontrol, occupancy, or a lighting control system?
  • What code constraints apply? National Electrical Code, local amendments, and energy codes.

This matters more than the aesthetic. A contemporary chandelier over a lobby table is not the same as a patio chandelier over an outdoor dining area. The outdoor fixture needs a wet or damp rating, corrosion-resistant hardware, and a control setup that doesn't fight the daylight. If you skip this step, you'll order a beautiful fixture that fails in 18 months. Not ideal, but workable? No, not workable.

Step 2: Write down the exact Acuity Brands Lighting replacement part numbers

Here's the phrase that keeps me out of trouble: Acuity Brands Lighting replacement parts are easy to buy only when you use the OEM part number. Don't rely on the distributor's short code. Get the catalog number from the spec sheet. If you have an existing fixture, check the label inside the driver compartment and order from that number.

I've also called about a part stocked at the Acuity Brands Lighting Inc Crawfordsville, Indiana facility. It's a manufacturing and distribution location for Acuity Brands Lighting, and they can tell you what's in stock and what's a production run. So glad I made that call once. Almost shipped an unapproved substitute to save three days, which would have violated the project spec.

Acuity Brands publishes product specifications and photometric files on its website. I checked them in January 2025 before writing this. If a part number isn't in the current spec sheet, it may be obsolete. Move on now, not after you've collected a bid.

Step 3: Compare total cost of ownership, not price per fixture

A person in my position hears 'this one is cheaper' all the time. I've stopped caring about the unit price. Total cost of ownership (TCO, in procurement-speak) includes the fixture price, driver compatibility, controls, mounting hardware, shipping, potential expedite fees, and labor for future repairs.

For example, I tracked $180,000 in lighting spending over six years. The biggest overruns didn't come from the fixture cost. They came from expedited shipping and rework after the cheap part failed. Generic or 'compatible' drivers were a recurring theme. A $12 savings on a driver turned into a $180 service call and a $40 part after the driver failed. The most frustrating part of all this is that the failure happened after the warranty period, so the labor was on me.

That doesn't mean every proprietary part is worth the premium. It means you need a spec and a price list that separates the fixture, the driver, the control, and the replacement part. Then compare line by line.

Step 4: Verify the controls before you commit

Acuity's portfolio includes DTL dark-to-light photocontrols. The DTL name means the control switches the load based on ambient light: dark means on, light means off. Sounds simple. In practice, I've seen photocontrols pointed at a parking lot pole, covered by a bird's nest, and aimed at a floodlight from an adjacent building. All three caused the same problem: the light stayed on during the day. That's not a sensor failure. That's a placement failure.

When you buy a control, check three things:

  • NEMA twist-lock or button mount? The fixture must match the control base.
  • Input voltage matches the circuit? A 208V rating is not the same as a 277V rating.
  • Does the control have a manual override option? For a patio chandelier, a photocontrol that switches the whole circuit can annoy diners. Sometimes you want a timeclock instead.

If you're ordering a contemporary chandelier for an interior lobby, you likely need dimming control, not a photocontrol. Ask the fixture manufacturer which dimmer is tested with the LED driver. This is where hidden costs show up. The dimmer might be $40, or it might be $140 and require a neutral wire (which, honestly, nobody budgets for).

Step 5: Plan the wiring and switch function before install day

The phrase 'how to wire light switch to light' is searched by people who need to understand the basics. I'll give you the basics, but I am not an electrician. If you're not comfortable with a voltage meter, stop and hire a licensed electrician. That's not a disclaimer; it's the cheapest part of the project.

The simple version: a wall switch connects the hot wire from the panel to the fixture's black wire. The white neutral goes to the fixture's white, and the ground is bonded to the fixture's ground. The switch itself has a line or common terminal and a switch leg terminal that runs to the light. In most cases, the power comes into the switch box first, then one cable goes up to the fixture. Some wiring configurations use a switch loop with no neutral at the switch. The confusing part is always the same: the white wire in the switch loop is not a neutral. It's the switch leg using white as a hot conductor. I've seen an experienced electrician shake his head when a homeowner says that. Respect the rules.

Also remember NEC 210.70: habitable rooms need a wall switch-controlled lighting outlet. A chandelier is usually switched from the wall or via a control system. If you're replacing a pull-chain fixture with a contemporary chandelier, don't just hang the chandelier and leave the switch work to 'check later.' Later becomes never, and the inspector notices.

For a patio chandelier, the wiring also needs to be rated for outdoor use and include a weatherproof box. The fixture canopy needs space for the wires and a ceiling support that can handle the weight. That's another line on the TCO spreadsheet: mounting hardware, a support element, and maybe a junction box relocation.

Step 6: Build in lead time and logistics

Let's say the fixture is physically available and the part numbers are right. The last hidden cost is delivery. I learned this with a hotel patio chandelier that had a cracked glass shade on arrival. The replacement shade was in stock, but it shipped via ground freight from a warehouse that wasn't the Crawfordsville facility. It arrived five days later, and the electrician had already moved to another job. We paid a second trip fee. The total was $300 over budget for a $14 shade.

My rule today: if the project has a hard deadline, add two weeks of buffer to the delivery date. Use certified or freight shipping with crating for large fixtures. Ask for photos of the crated fixture before it leaves the warehouse. And always keep the original packing materials until after installation. If you need to file a claim, the photos and boxes are your evidence. Good packing materials are not waste; they're insurance.

Common mistakes I still see in lighting POs

At the end of the checklist, here are the mistakes that keep coming back:

'Same as sample' means nothing. I said 'same as sample' once. The vendor heard 'same style, different finish.' When the crates arrived, the finish was bronze, not black. We were both using the same words, but we meant different things. Discovered when the chandelier was halfway out of the crate. Write down the finish code, not the verbal description.

'Cheapest alternative' costs more. I saved $76 on an alternative mounting bracket for a contemporary chandelier. The bracket didn't fit the existing canopy. I then paid a machine shop $110 to modify it. That's $34 more than the official part. Simple numbers, stupid mistake.

Don't trust 'guaranteed lowest price'. I don't need the lowest price. I need a truthful delivery date and a clear list of what the price includes. A vendor who says 'we're not the cheapest, but we'll have it there Friday' is more useful than one who says 'we always beat the quote.'

Photocontrols need a clear line of sight. A DTL dark-to-light sensor facing the wrong direction will cause complaints from everyone passing through the parking lot. Aim it toward the northern sky, away from fixtures, and check it after installation. This is the step that most people ignore, and it costs nothing.

If you take one thing from this article, let it be this: a lighting purchase is not a fixture purchase. It's a system purchase. The fixture, driver, control, wiring, mounting, and replacement parts are one unit. Plan for all of them before you create the PO. Then your 'cheap' choice won't become an expensive redo.
