Final Checklist
When I first started specifying lighting controls for commercial projects, I made the classic rookie mistake: I assumed the cheapest quote was the best deal. Three projects and a couple of budget overruns later, I realized that the upfront price tag is just the tip of the iceberg. The real cost lives in installation labor, compatibility headaches, future upgrades, and even the time you spend troubleshooting flickering LEDs.
This checklist is for anyone who has to justify their lighting control choice to a finance committee or client. It’s built around seven steps I now follow before writing a PO. Each step has a check point you can literally tick off.
Step 1: Map Your Load Types and Control Zones
Lutron offers dozens of dimmers, switches, sensors, and power packs. But not every load plays nice with every controller. Before you even look at price lists, list every fixture in the project: LED downlights, dimmable track heads, 0-10V drivers, magnetic low-voltage tape, line-voltage screw-in bulbs, and – yes – that shade chandelier the architect specified. Write down the voltage, wattage, and whether it’s dimmable.
Check point: Do you have a load schedule that shows driver type (trailing edge vs. leading edge) and dimming protocol (forward-phase, reverse-phase, 0-10V, DALI)?
Here’s the thing: a $25 Lutron Diva dimmer might work perfectly with one brand of LED downlights but cause audible hum with another. I learned that the hard way when we installed 50 fixtures in a conference room and half of them buzzed. The cheapest fix was swapping to a Maestro model with adjustable low-end trim. That added $15 per unit – and a day of electrician rework. TCO, not sticker price.
Step 2: Choose the Right Product Family – Don’t Over-Buy or Under-Buy
Lutron’s three main families for most commercial work are Caséta (residential / light commercial), Maestro (step up, multi-location controls), and Diva / Ariadni / Skylark (one-way dimming). For larger projects with 0-10V drivers you’ll need the compatible power packs or interfaces.
Check point: Have you matched the family to the control requirements (multi-way switching, centralized scenes, integration with BMS)?
I went back and forth between Caséta and Maestro for a 15-zone office project for nearly a week. Caséta was cheaper per zone and included a Smart Bridge, which looked great on paper. But the client needed three-way control in every conference room – Caséta’s Pico remotes work, but Maestro’s wired companion switches are simpler for a facilities team. I chose Maestro. The extra $1,200 upfront saved two hours of explaining to a frustrated electrician later. Grant it, that’s a judgment call, not a mathematical decision.
Step 3: Calculate the Real Energy Savings (Not the Marketing Numbers)
Lutron claims energy savings of 35–60% with dimming and occupancy sensing. I’m not saying those numbers are wrong, but they assume perfect usage patterns. In my experience, actual savings depend on how aggressively you set the high-end trim and the time-out delay on vacancy sensors.
Check point: For each zone, estimate annual kWh consumption with and without controls using the actual wattage and expected occupancy. Use a simple spreadsheet.
To be fair, the FTC advertising guidelines require claims to be substantiated, so Lutron’s marketing is vetted. But in a real building, I’ve seen programmed ‘daylight harvesting’ zones that actually use more energy because the photosensors kept the lights on when daylight was adequate but the delay was too long. That’s a commissioning cost you should budget for.
Roughly speaking, you can expect 20–30% savings in mixed-use spaces if the controls are well-commissioned. The ROI period: 2–4 years on the hardware alone, depending on local rates. Plug that into your TCO model.
Step 4: Verify Compatibility – Especially with the ‘New’ Diva LED+
The Lutron Diva LED+ dimmer (model DVCL-153P) is a popular retrofit choice because it works with many LED bulbs without a neutral wire. But “many” is not “all.” I’ve seen flickering on cheap Chinese downlights that the dimmer could not handle. Lutron publishes a compatibility chart on their website – print it out and compare each fixture model.
Check point: Every fixture being dimmed is listed on Lutron’s compatibility tool (or equivalent test results). If it’s not, order a sample and test it at your bench before buying 200.
That test saved me once. We had a client who wanted 400 track heads with a specific brand. The Lutron Diva LED+ was on the compatible list, but only for the version 2 of the driver. The client’s fixtures were version 1. We caught it before shipment – avoided a $2,500 restocking fee and a month-long delay.
Step 5: Include Installation and Commissioning Costs in Your Comparison
I know you’re comparing the hardware costs between Lutron and maybe a cheaper brand like Leviton or Legrand. But the real cost difference often lies in wiring complexity. Lutron’s Maestro requires a neutral wire at every switch location. If your building is older and doesn’t have neutrals in every box, you’ll need either a rewire (at $50–100 per device) or use a no-neutral model like Diva LED+. The latter may seem cheaper, but it has a lower load limit and more compatibility restrictions.
Check point: Calculate the full installed cost per zone: hardware + labor + any electrical upgrades needed + commissioning time. Compare across families, not just by product.
In a recent project in Corona del Mar, CA, the electrician quoted $15 per switch for installing Maestro vs. $12 for the basic Diva. Not a huge difference, but the Maestro required a neutral which wasn’t present in half the locations. The extra wire pulls added $800 to the total. That pushed the TCO of Maestro slightly above the Diva for that project. We went with Diva for those zones and used Maestro only where multi-location control was needed.
Step 6: Factor in Future Expandability and Standardization
Nothing costs more than ripping out a control system later because it doesn’t integrate with the new smart building platform. Lutron has several ecosystems: Caséta (Wi-Fi, cloud-based), RadioRA 2 / RA3 (Hub-based, more professional), and HomeWorks (highest end). The lower-cost systems often limit the number of devices and zones.
Check point: Does the system you’re choosing allow you to add at least 20% more zones later without replacing the hub? Can it integrate with BACnet or KNX if needed?
I learned this when I skimped on a HomeWorks system for a residential project and used RA2 instead. Two years later the homeowner wanted motorized shades and outdoor spotlight control. The RA2 could handle shades, but only with an expensive interface. Meanwhile, a HomeWorks system would have had native shade control. The upgrade cost (replacing the main processor) was $4,000. That’s a lesson in total cost.
Step 7: Watch Out for These Hidden Costs (and How to Avoid Them)
- Restocking fees: Some distributors charge 25% on returned Lutron products. Order samples first, especially if you’re trying a new fixture compatibility.
- Legal and compliance costs: In some jurisdictions (California Title 24, ASHRAE 90.1), you need specific control types like vacancy sensing and daylight zones. Make sure your system supports those – otherwise you’ll pay for re-engineering.
- Training your team: Lutron’s software for programming RA3 or HomeWorks requires training. Factor in the time for your electrician to get certified, or hire a Lutron specialist (hourly rates around $100–150).
- Future firmware: Wi-fi connected systems like Caséta may require a cloud subscription for remote access after the first year. Read the fine print.
Final Checklist
Before you sign that PO, tick these off:
- Load schedule created and compatibility confirmed per zone.
- Product family selected based on control needs, not just price.
- Energy savings modeled with realistic assumptions (not marketing numbers).
- Sample test performed for any non-standard fixture.
- Installed cost calculated including labor, wiring, and commissioning.
- Future expansion plan considered (hub limits, integration options).
- Hidden fees identified and mitigated (restocking, compliance, training).
This list isn’t exhaustive, but it covers the biggest budget killers I’ve seen in six years of managing lighting control procurement. The cheap option almost never is when you account for installation and compatibility. Lutron makes great gear, but the right system for your project depends on more than a spec sheet. Do the TCO math – your CFO will thank you.
