The Exterior Lighting Ordering Checklist: 7 Steps I Run Before Any Purchase

I'm the office administrator for a 180-person company. I manage all the facilities ordering—roughly $340,000 a year across 14 vendors, everything from janitorial supplies to the exterior lighting on our three buildings. I answer to operations on one side and to finance on the other, which means I get blamed if a fixture arrives wrong and I get blamed if the invoice doesn't clear.

Here's the checklist I run before I place any exterior lighting order. Seven steps, no exceptions. Because the one time I skipped one, it cost us $1,900 and two weeks.

Step 1: Confirm it's actually an outage

Before I price out a single replacement fixture, I ask the question that comes up more often than you'd think: is there a light outage in my area? I've had three calls this year about "the parking lot lights are dead" that turned out to be a grid issue on the utility's side. Nothing wrong with our fixtures at all.

Pull up your utility's outage map first. If there's a known service interruption on your block, wait it out. Ordering replacements for a problem that solves itself in four hours is a great way to burn a purchase order and look jumpy in front of your operations lead.

Step 2: Get the model number, not a photo

My first mistake in this job was trusting pictures. Someone sends me a smartphone photo of a bollard light—mid-traffic, bad angle—and says "order that." I did it once. What arrived was the wrong height, wrong finish, and a beam pattern that lit the shrubs instead of the walkway.

A bega bollard light, just as an example, isn't one product. It's a family. Height, wattage, beam spread, finish, mounting—each of those is a variable. Two fixtures that look identical in a photo can have different everything on the spec sheet.

So my rule now: no model number, no order. If the requester can't find it, I get the spec sheet from the vendor's US site and confirm it in writing. Takes five minutes. Saves two weeks.

Step 3: Match the fixture to the actual environment

This is where the downlight exterior versus interior confusion bites people. They're not the same. An interior downlight in an exterior soffit works for about one rainy season, then the corrosion starts.

Three things I check before I check price:

• IP rating. Anything outdoors needs at least IP65 if it's near irrigation or weather exposure. IP44 for a covered entryway is often fine, but I verify.
• Corrosion resistance. A wall downlight on a building near the coast is a different spec than one in a dry inland lot. Salt air is unforgiving.
• Ambient temperature rating. Sounds fussy until a fixture fails in July because it was rated for a cooler climate range.

I'm fairly conservative on this step. Somewhat more than the vendor thinks is necessary, honestly. But the callback cost of a failed fixture outweighs the premium every time.

Step 4: Check the driver (most people skip this)

This is the step I see almost nobody do, and it's the one that kills budgets.

LED fixtures aren't plug-and-play. The LED driver matters—whether it's integrated, remote, and what the input voltage and dimming protocol are. If you're swapping fixtures into an existing system, the new fixture may not talk to the old driver. Or the driver may not fit in the housing.

I ask three questions every time, in writing:

1. Is the driver integral or remote?
2. What's the input voltage—120V, 277V, or universal?
3. If the site uses dimming, what protocol does the driver accept?

For bega US lighting products specifically, I've learned to confirm the US-market spec rather than assume it matches the European datasheet. Voltage, dimming, and even some finishes can differ. Doesn't mean they're wrong—just means I check.

Step 5: Verify the vendor can actually invoice

I'll be honest: this step comes from a scar. In 2022 I found a great price on a set of exterior fixtures—about $1,100 cheaper than our regular supplier. Ordered 24 units. The vendor sent a handwritten receipt. No proper invoice, no tax ID.

Finance rejected the expense report. I ate $2,400 out of the department budget because the accounting team couldn't reconcile it. My VP asked me one question: "Why didn't you check?" I didn't have a good answer.

Now I verify invoicing capability before I place any order over $500. Proper invoice template, tax ID, net terms, and a named point of contact. It's a five-minute email. Worth it.

Step 6: Lock the lead time in writing

"Two weeks" spoken over the phone becomes six weeks when you're staring at a half-lit parking lot the night before an inspection. It's happened to me twice. Both times the answer was "we said two weeks, but that was an estimate."

Now I get the ship date in an email before the PO goes out. If the vendor won't put it in writing, that's a signal. Not an automatic no, but a signal. I plan around a written date, and I build in a two-week buffer for anything that matters.

Step 7: Stage one fixture before the full order

This is a step I picked up from a contractor on a different project. Order one or two units. Install them. Check the color temperature, the beam angle, the light throw, and how it actually looks against the building at night.

Color temperature is the sneaky one. A fixture spec'd at 3000K and one at 4000K can both look "white" on a datasheet and completely different in the courtyard. And beam spread on a wall downlight—narrow versus wide—can change the whole look of a facade.

Yes, staging costs a little more upfront. Yes, it adds a week. It also prevents the "24 units and none of them are right" conversation, which is a much more expensive week.

Common mistakes I still watch for

Even with the checklist, I catch myself slipping sometimes. A few things to keep on your own list:

• Ordering by photo. Already covered, but it's the most common one. Resist it.
• Assuming drivers are universal. They aren't. Ask.
• Skipping the sample. Tempting when you're behind schedule. Don't.
• Not checking the outage first. I still have to remind myself. A dark parking lot is not automatically a broken fixture.
• Forgetting time zones and shipping. A fixture that ships from the East Coast on Friday won't help a Monday installation on the West Coast.

One note on timing: I put this checklist together from experience through early 2025. Product lines, spec sheets, and lead times change—bega's US catalog included. Verify current specs and pricing before you commit to a PO. The process holds up; the data underneath it doesn't stand still.

The list isn't glamorous. But I've stopped getting the "why did this arrive wrong" email, and that's worth more to me than saving a few bucks on an order that ends up costing double.
