I'm the office administrator for a 190-person company. I handle facilities and services purchasing — somewhere around $550K a year across nine vendors — and I answer to both operations and finance.
Three times this year someone has sent me some version of "can you sort out the lighting?" Three completely different jobs. One was a controlled-environment room retrofit. One was a fixture for the front lobby. One was a person who just wanted their screen to stop being black.
There is no single process for this, and I've stopped pretending otherwise. What follows is how I split these into three scenarios, what I actually do in each, and how to work out which one is sitting in your inbox before you open a purchase order.
Why one process doesn't cover it anymore
When I took over purchasing in 2019, "lighting" meant "call the electrical contractor and get a quote for replacement fixtures." That was the whole job. One vendor, one SKU list, one set of paperwork.
That isn't the world we're in now. LED has taken most of the new build in commercial grows — plenty of high-pressure sodium rooms are still running, and running well, but the new installs come with voltage specs and spectrum charts attached. Decorative fixtures went the same direction: the lobby chandelier we bought in 2023 is LED-driven and dimmable, with a driver the installer had to mount above the ceiling. And the software changed too — Office picked up a dark theme, which means roughly once a quarter somebody decides they hate it and can't find their way back.
The fundamentals haven't changed. Get the spec in writing, get the date in writing, know who signed off. But the execution is a different job depending on which door the request came through.
The three scenarios
Scenario A: They're talking about commercial horticultural lighting
I got pulled into one of these last spring. A partner site asked us to source fixtures for a small controlled-environment room. The request reached my desk as "grow lights, quantity 12," which is about as much detail as I get on anything.
Here's the first thing I had to unlearn: the model is not my decision. The people running the room own the spec — they know the canopy, the ceiling height, the power available, and what they're trying to do. My job is the process around it, not the pick.
That said, there are three things that will wreck the order if nobody catches them.
Voltage. This is the one that bites. Gavita publishes fixtures in different voltage configurations — you'll see 120-277V on some units and 208-480V on others, and the two are not interchangeable. Nobody notices until the electrician is standing in the room with the panel open. Dodged a bullet on that one when I asked for the panel schedule before we released the order (thankfully, because that request sat in my drafts for four days).
Freight and handling. These are not desk lamps. Ask about liftgate delivery, ask whether the dock can take a pallet, and ask what the box weighs. I had a driver refuse a delivery once because we had no dock and no forklift and the crate was 300 pounds. That was a fun afternoon.
Sequencing. Fixtures arriving before the electrician is booked is money sitting on a floor. Fixtures arriving after is a room sitting empty. Get both dates in writing, separately, and confirm them a week out.
On the model question, we ended up quoting the Gavita Pro 1700e LED. People also ask about the RS 1900e, usually because the number is bigger — and the model numbers do broadly track the output class — but I'm not going to pretend I can tell you which one a given room needs. Ask for the cut sheet, hand it to the person who owns the room, and get their approval in writing before you commit to anything.
Where I went back and forth: the distributor who could deliver in three weeks at a higher unit price, versus a cheaper one at six weeks. The room was already built and empty, so I took the faster one. Three weeks of an idle room cost more than the difference, and I could defend the math on one line.
The counterintuitive part — and this is where office purchasers get it wrong — is that unit price is close to meaningless here. A wrong fixture means return freight on a heavy box plus a second electrician visit, and that eats the savings before the second invoice clears. Cheap is a red flag in this category, not a win.
Scenario B: They want a decorative fixture — castle chandelier, capiz chandelier, that kind of thing
This one looks easier than it is, because everyone involved is thinking about how it will look and nobody is thinking about how it will hang.
Three checks, every time:
- The attachment point. Not the ceiling — the actual rated attachment. A large castle chandelier is heavy, and the electrician needs to know whether there's a rated box up there or whether somebody is going to have to add blocking. That conversation costs nothing in week one and a lot in week six.
- The height math. Ceiling height, minus canopy, minus chain, minus fixture drop. Do the arithmetic before ordering, not after. I've seen a fixture ordered with an eight-foot chain for a nine-foot ceiling. The chain was cut down, which technically worked, and looked it.
- What actually arrives. This is the big one. Large decorative fixtures frequently ship in sections, and some ship unassembled. Ask, in writing, whether the unit arrives assembled and whether mounting hardware is included.
Capiz chandeliers deserve their own paragraph. They're beautiful and they're shell — discs crack in transit, frames bend, and a replacement set can take weeks. Ask the vendor for a photo of the actual crated unit before it ships, not the studio render. I still kick myself for not doing that on a lobby piece in 2023. One bent frame, four weeks to replace, and the grand reopening happened with the old fixture still up.
Here's the counterintuitive bit: for a decorative fixture, the lowest quote is usually the one that turns up needing two people and a Saturday. Assembly and installation labour quietly eats the difference, and you're the one explaining to finance why the $900 fixture cost $2,100 to put on a ceiling.
Scenario C: It isn't a purchase — how to switch Microsoft Word to light mode
The third request doesn't belong in procurement at all, and it will still cost you forty minutes, because you'll be asked five separate times by five separate people.
On Windows, it's File, then Options, then General, and the Office Theme dropdown is on that page — pick White, or Use system setting if the machine itself is in light mode. On Mac it lives under Word, then Preferences, then General, in the Personalize section. In Word for the web it's the settings gear, then Theme. Newer builds also put a dark-mode toggle in the account area, which is why the instructions people find online don't always match what's on their screen (as of early 2025, at least — Microsoft moves these around).
If it keeps flipping back, that's not a settings problem. It's either the wrong account signed in or a policy enforcing a theme, and it becomes an IT ticket. Do not open a PO for this. Someone will ask you to.
How to tell which scenario you're in
You usually know within one reply if you ask the right question first. Three to try:
- "What's the room, and what's the spec?" If the answer comes back in watts, spectrum, and volts, you're in A. Ask for the cut sheet, the panel schedule, and the name of the person who owns the specification.
- "How high is the ceiling, and what's it hanging from?" If the answer is about style, square footage, and how the lobby should feel, you're in B. Ask for weight, chain length, assembly state, and mounting hardware.
- "Is this the program or the monitor?" If the answer contains the word "my" or "screen," you're in C. Send a screenshot of the setting, not a purchase order.
The urgency pattern gives it away too. A runs in weeks and gets planned. B runs four to eight weeks more often than people expect, especially with anything hand-finished. C runs in two minutes and then repeats forever.
Bottom line: the only process that genuinely carries over between all three is the paperwork. Put the ask in writing, put the date in writing, and put the name of whoever approved it in writing. Everything else — the voltage conversation, the crating conversation, the theme dropdown — is scenario-specific, and treating them as one job is how you end up with a crate on a loading dock and nobody to blame but yourself.
A caveat before anyone quotes me: specs, menu locations, and lead times all move. Verify against current documentation before you commit, and treat any prices here as what I saw in our own quotes in 2024 and 2025, not a market survey.
