Who this checklist is for (and why I made it)

If you're ordering lighting for a hotel, restaurant, office, or residential project—and especially if you're doing it through a designer series or a brand like Visual Comfort—this is the checklist I use before every single purchase order. I'm not a lighting designer. I'm the person who processes the orders, catches the mistakes, and eats the cost when something goes wrong.

I've been handling commercial lighting orders for eight years. In that time I've personally made—and documented—11 significant mistakes, totaling roughly $14,000 in wasted budget, redo costs, and rush fees. (Should mention: that number doesn't include the soft costs, like the client relationship damage after a missed install date.) Now I maintain our team's pre-order checklist. We've caught 47 potential errors using it in the past 18 months.

Here are the seven steps. They're in the order I actually do them, not the order that looks good on a slide.

Step 1: Diagnose the circuit before you blame the fixture

This one is first because it's the most common thing I see buyers skip. When someone says "why did the light go out in my area," the instinct is to assume the fixture failed. Nine times out of ten, it's not the fixture.

In September 2022, we had a hotel corridor where six fixtures went dark within a week of install. I assumed we'd received a bad batch. Didn't verify the circuit first. Turned out the dimmer load was wrong—the fixtures were fine, the control was the problem. We spent $890 on a needless replacement order plus a one-week delay before an electrician pointed it out.

What to check:

  • Total wattage on the circuit vs. dimmer rating
  • Voltage drop on long runs (especially outdoor and corridor lighting)
  • Driver compatibility with the dimming protocol (0-10V, TRIAC, DALI—they are not interchangeable)
  • Whether the "out" lights are on a shared switch leg

I don't have hard data on how often this is the actual cause, but based on our own service tickets, my sense is it's the culprit in at least half of "why did the light go out" calls.

Step 2: Bathroom downlights need wet-location specs, not just a nice trim

Bathroom downlights are where I see the most expensive "it looked right in the photo" mistakes. The trim style is the least important spec. The important ones are IP rating, cutout diameter, and color temperature consistency.

In 2019, I ordered 60 downlights for a boutique hotel bathroom renovation. The model matched the design intent exactly. What I didn't check was the cutout size—the ceiling had been framed for a 2.5-inch opening, and the fixtures needed 2.75 inches. We had to send back the entire order. The redo cost about $1,200 in restocking and expedited shipping, plus a three-day delay on the electrical rough-in.

What to check:

  • IP44 or higher for bathroom zones 1 and 2 (IP65 if it's in a shower)
  • Actual cutout diameter—measure the ceiling, don't trust the spec sheet alone
  • Color temperature consistency across the batch (2700K vs. 3000K mismatch is visible and annoying)
  • Trim finish sample against the actual tile or stone

Most buyers focus on the trim style and completely miss the cutout diameter. The trim is what you see. The cutout is what decides whether the install happens on schedule.

Step 3: Size the chandelier with math, not with photos

A small chandelier in a product photo looks bigger than it will in a room. I've made this mistake twice—once with a Hampton small chandelier on a residential project where the client thought "small" meant "subtle." It didn't. It meant "lost in the ceiling."

The industry rule of thumb that actually works: add the room's length and width in feet, and that number in inches is a reasonable maximum chandelier diameter for a typical ceiling height. For a 12×14 foot dining room, you're looking at roughly a 26-inch diameter max. For lower ceilings, scale down. For double-height spaces, you can go larger, but the hanging height matters more than the diameter.

What to check:

  • Ceiling height at the actual mount point (not the average room height)
  • Hanging height: bottom of the fixture should clear 30-34 inches above a table, 7 feet above a walkway
  • Canopy size vs. the electrical box—some designer canopies are wider than a standard 4-inch box
  • Weight and whether the ceiling needs blocking

This worked for us on a recent restaurant project, but our situation was a standard 10-foot ceiling with a known structural grid. If you're dealing with a historic building or a floating ceiling, the calculus might be different—get the contractor to confirm blocking before you order.

Step 4: Read the material spec, not the collection name

Designer series names do a lot of marketing work. They don't always tell you what the fixture is made of. With a brand like Visual Comfort, you're often dealing with crystal, alabaster, plaster, or brass—and those materials have very different care requirements, weight profiles, and price points.

I once ordered what I thought was a crystal Clarissa chandelier for a client who wanted a statement piece. The spec was actually a crystal-look glass with a plated frame. It looked fine in photos. In person, under the client's lighting, it read as "hotel lobby budget" rather than "bespoke." We ate the return shipping and reordered. That one cost $620 in freight and a two-week delay.

What to check:

  • Primary material (crystal vs. glass, solid brass vs. plated steel, real alabaster vs. resin)
  • Whether a material sample is available before you commit to a full order
  • Care and cleaning requirements—plaster and alabaster are not for high-touch or high-humidity areas
  • Weight per fixture vs. the mounting hardware supplied

Visual Comfort lighting design tends to lean on material honesty. If the spec says plaster, it means plaster. That's a good thing for the right space and a problem for the wrong one.

Step 5: Confirm lead time and stock status in writing

Designer series are not always stock items. Some are made to order. Some are stocked in limited finishes. I learned this the hard way in Q1 2024, when I assumed a collection was in stock because the website didn't say otherwise. It wasn't. The lead time was 10-12 weeks. The project needed it in four.

That mistake affected a $3,200 order and pushed a hotel mock-up room by three weeks. The client was understanding—once. I don't plan to test that again.

What to check:

  • Stock status for the specific SKU and finish (not just the collection)
  • Lead time in writing, with a ship date, not a "typically ships in" range
  • Whether the finish is a stock finish or a made-to-order finish
  • Return policy on made-to-order items—usually none, so get it right the first time

I'm not 100% sure how other brands handle this, but with designer collections, assume made-to-order until proven otherwise.

Step 6: Ask about minimums and mixed-batch policies—even on small orders

Here's where I'll get on a soapbox for a minute. When I was starting out, I placed a $200 order for samples and a single fixture. One supplier made it clear that my order was an inconvenience. I still remember that. The vendors who treated my $200 orders seriously are the ones I still use for $20,000 orders today.

Small doesn't mean unimportant—it means potential. If you're ordering two bathroom downlights to test before a 200-piece rollout, that's a reasonable strategy. Ask about it directly.

What to check:

  • Minimum order quantity (and whether it's per SKU or per order)
  • Mixed-batch policy—can you combine finishes or sizes to hit a minimum?
  • Sample policy—do sample costs credit toward a future order?
  • Whether small orders get the same lead-time priority as large ones (they often don't, and that's worth knowing upfront)

I can only speak to our own approach, but we don't penalize small orders. The math is simple: today's sample order is next year's project order.

Step 7: Run the pre-order checklist (the one that catches the boring mistakes)

This is the final pass. It's not glamorous. It catches the stuff that costs $400 and a week of your life.

  1. Every SKU number matches the quote, the spec sheet, and the purchase order—line by line
  2. Every finish is specified by name and code, not by "the dark one"
  3. Cutout dimensions and ceiling heights are confirmed against the actual site, not the drawing
  4. Lead times are confirmed in writing with a ship date
  5. Shipping address and receiving hours are correct (I've had a freight truck arrive at a locked site—that's a $250 redelivery fee)
  6. Payment terms and return policy are attached to the order file
  7. One person other than me has looked at it

That last one is the most important. I've caught more errors on a second read than on any spec sheet. It's also the step everyone skips when they're in a hurry.

A few closing notes (the stuff that doesn't fit neatly into a step)

The checklist won't save you from a genuinely wrong design decision—that's a different problem. What it will save you from is the unforced error: the wrong cutout, the wrong finish, the assumed lead time, the "small" chandelier that wasn't small enough.

I wish I had tracked my error rate more carefully from the start. What I can say anecdotally is that since we formalized this list in 2023, our order-error rate has dropped noticeably—and the errors that still slip through are usually the ones where someone skipped Step 7.

If you're ordering through a designer series or a brand like Visual Comfort, slow down on Steps 4 and 5. Those are the two where the spec sheet looks fine and the project still goes sideways. The fixture is rarely the problem. The assumption is.
