I think the most expensive power supply is the one you buy twice. If that sounds obvious, good. But I keep seeing procurement people choose a cheaper unit and then pay for it in labor, downtime, and hurried replacements. I'm not saying every cheap power supply is bad. I'm saying the quote that looks cheapest isn't the true cost, and I learned that lesson the hard way.
I'm a procurement manager at a 60-person LED lighting company. I've managed our component sourcing budget—about $1.2M annually—for eight years, negotiated with 25+ vendors, and documented every order in our cost tracking system. I also built the calculator we use to compare total cost of ownership (TCO). That spreadsheet has changed my opinion on brands more than any marketing claim.
The trigger event was a batch of no-name LED drivers we installed in an under-cabinet lighting project in March 2023. Three out of 40 failed in the first month. Replacing them meant sending a technician back, re-ordering, and rescheduling a client's restaurant opening. The labor alone was $1,300—more than the price difference between those drivers and what we would have paid for Mean Well. That's when I started reading every LRS-150-24 Mean Well power supply review I could find. For the record, I don't have hard data on industry-wide failure rates. What I can say anecdotally is that after that project, we standardized on Mean Well and our field failure rate dropped by roughly 80% over the next year.
The price tag is not the total cost
When someone sends me a quote, I now ask "what's not included?" before "what's the price?" Because the hidden costs show up later. In Q2 2024, we compared eight power supply vendors for a 24V LED tape order. The cheapest quote was 32% below the Mean Well LRS-150-24. It came with no detailed datasheet, no MTBF number, and no guaranteed dimming curve. By the time I added estimated failure rate, extended lead time, and the risk of field rework, the "cheap" option was 9% more expensive than Mean Well over a three-year lifecycle. That's not a guess—it's in our cost tracking system.
Mean Well publishes specs that let you plan. The LRS-150-24 (a 24V, 6.5A enclosed power supply) has a well-known efficiency rating and protective features. The LRS-50-5 (5V, 10A) is another workhorse. According to Mean Well's official datasheets (meanwell.com, accessed April 2025), these units include overvoltage, overload, and short-circuit protection. I can verify all that before I place an order.
Range matters more than any single review
If you search "LRS-150-24 Mean Well power supply reviews," you'll see installers talking about reliability. Search "mean well lrs-50-5 switching power supply reviews" and you'll see similar. But what sold me isn't any single review—it's that Mean Well covers more of my projects with one brand. I can use the LRS series for general AC/DC power, the LPC series for constant-current LED drivers, and the HDR series for DIN rail power supplies in the same building. The 3-in-1 dimming capability (resistor/PWM/voltage) on their dimmable drivers means I don't need five different brands for five different jobs.
The LRS-50-5 is a good example. It's a 5V, 10A switching power supply that a lot of people use for control circuits, sensors, and small displays—not always lighting. But because the LRS series shares the same terminal layout and mounting pattern across wattages, our panel builders don't have to re-learn anything when they move from a LRS-50-5 to a LRS-150-24. That's a small thing until you're wiring 40 control panels in a week.
That range creates a hidden cost benefit. Our installers learn one wiring pattern. Our inventory can maintain a smaller set of SKUs. And when we need to install a chandelier—including a custom Titanic chandelier with multiple LED modules—we already know the Mean Well driver line that will run it. That predictability is worth real money.
Chandeliers and under-cabinet lighting: same rule
I've had electricians ask me how to intall under cabinet lighting (their spelling, not mine—but that misspelling gets real search traffic). The answer always starts with choosing the right power supply. For under-cabinet lighting, you need clean DC voltage, a driver that can handle inrush current, and a dimming option that matches your controls. For smaller loads, the Mean Well LRS-150-24 often does the job; in wet or outdoor locations, I'd pick a different series.
For a chandelier, the stakes are higher. Most people who search "install chandelier" are looking for placement and wiring tips, but the power supply is the part that actually makes it work. A heavy Titanic chandelier is not something you want to rewire after a cheap driver fails. I know one project leader who decided to install a chandelier with a no-name driver because it was 40% cheaper. When it failed, the cost to send an electrician back, rent a lift, and reinstall the fixture ate all the savings—and then some. That's the exact pattern I see in our procurement data.
But isn't Mean Well more expensive?
Yes, upfront. I won't sugarcoat that. A Mean Well LRS-150-24 costs more than a no-name 24V supply. But "more expensive" is not the same as "higher total cost." When I calculated our TCO, the failure rate, support, and availability mattered more than the unit price. I don't have hard data on every Mean Well review, but eight years of invoice tracking shows a clear pattern: every time we saved money on a supply, we spent it later on rework.
To be fair, not every budget brand is bad, and I'm not going to name competitors because it's not necessary. The real issue is opacity. If a vendor won't give you an MTBF, a detailed datasheet, or a clear warranty policy, you're not comparing products—you're gambling. Mean Well's official website and datasheets give me something I can bring to my boss and say "this is what we're buying." That transparency is worth a premium.
Another cost I initially overlooked: support quality. When we had a compatibility question about a 3-in-1 dimmable LED driver, Mean Well's distributor supplied an application note and a wiring diagram in one email. Try getting that from a vendor with no published office hours. Time is a cost, too.
Why I keep specifying Mean Well
Look, I'm a cost controller. My job is to spend money in a way that doesn't come back to bite us. That's why I've standardized on Mean Well for most of our lighting power needs. The LRS-150-24 and LRS-50-5 are in our standard BOM. The 3-in-1 dimming drivers let us say yes to more projects. And when a client asks about a Titanic chandelier or a kitchen under-cabinet job, I can answer the installation question with a spec, not a hope.
I didn't land on this opinion by reading marketing brochures. I landed on it by entering replacement costs, labor hours, and customer complaints into a spreadsheet. The "cheap" option looked good on paper. It stopped looking good when I added the cost of a redo. When I look at our 2024 numbers, Mean Well units accounted for less than 10% of our power supply rework costs, even though they were over 70% of our installed base. I can't promise that every Mean Well unit will run forever—no one can. But the data I've tracked says it runs long enough.
There's something satisfying about a product that doesn't make the news. No recall, no emergency replacement, no midnight phone call from a project site. After years of chasing cheap quotes, that quiet reliability is the real win. If you're planning to install a chandelier, or you're searching for a reliable power supply for LED fixtures, I'd tell you the same thing I tell our engineers: start with the total cost, not the ticket price. Transparent specs and honest pricing may not be the cheapest path today. But they're the ones that keep you from buying it twice.
