Why I Switched My Facility to Dialight—Without Regretting the Cost

You’re probably asking yourself the same questions I asked two years ago

I’m a procurement manager at a 180-person chemical processing company. I’ve managed our lighting and electrical budget—roughly $180,000 in cumulative spending over 6 years—and I’ve negotiated with 12+ vendors in that time. When I first spec’d Dialight for our plant, I had a ton of questions. If you’re looking at switching to Dialight for industrial LED lights, here’s what I wish someone had walked me through from the start.

What’s the actual cost difference vs. standard industrial LED fixtures?

I keep a running TCO spreadsheet for every major line item we buy. In Q2 2024, when we compared a standard high bay (rated 50,000 hours) to a Dialight high bay (rated 100,000 hours with a 10-year warranty), the initial sticker shock was real. The Dialight fixture was about 65% more upfront. But when I factored in the re-lamp labor ($75 per fixture per event) and the downtime costs for our production line (roughly $340/hour in lost output), the break-even point hit in year 4. Over 10 years, we’re looking at a 22% lower total cost of ownership. The cheap option would have cost us more—just not on the purchase order.

You mentioned "explosion-proof" lights. Do I really need that for my warehouse?

My experience is based on about 200 orders of industrial lighting, mostly for hazardous environments and heavy industrial settings. If you’re running a dry goods warehouse with no flammable dust or vapors, I can’t speak to that directly. But here’s what I can tell you: if your facility has ​Cluster A | Division 2​ areas (or anything with combustible dust, gas, or vapor), non-rated fixtures are a liability. Our insurer flagged three of our old fixtures during an audit. Replacing them with Dialight’s Vigilant series wasn’t optional—it was compliance. The real eye-opener? The premium over a standard light is maybe 15-20%, but the cost of a single code violation can be $10,000 or more. Plus, you sleep better.

How do Dialight traffic lights and indicator lights stand up to outdoor conditions?

Don’t hold me to this exactly—I’ve only deployed Dialight indicator lights on about 40 installations—but from our experience with dock signals and yard lights, the durability is noticeable. We had a competitive brand’s indicator light fail in under 18 months due to moisture intrusion. The Dialight replacement has been running for three years with—and I’m not exaggerating—zero issues. What most people don’t realize is that Dialight’s traffic and indicator series use fully encapsulated electronics. That means no open air gaps where condensation builds up. It’s one of those inside-baseball details that matters if you’re in a humid or cold climate. Trust me, a $150 redo because of a $3 seal failure is not my idea of a good time.

Is Dialight friendly to smaller orders, or do they only take big accounts?

When I was starting out in procurement, the vendors who treated my $200 sample orders seriously are the ones I still use for $20,000 orders. Dialight’s distribution model means they work through a network of authorized distributors, so your mileage might vary depending on who you call. But in my experience, the larger distributors (think Graybar, Rexel, or WESCO) are happy to sell a single high bay or a dozen indicator lights. I’ve placed test orders for as few as 12 Safesite fixtures and received the same level of technical support as a 200-unit order. That’s not always true for premium brands. Some vendors treat small samples like a nuisance; Dialight’s distributor network didn’t.

So, LEDs don’t fail—right? I’ve heard that before.

This was true maybe 10 years ago when people were selling early LEDs as “fit and forget.” Today, any lighting professional will tell you that LEDs can fail—driver failures, thermal runaway, voltage surges. Dialight’s core advantage isn’t that they never fail. It’s that their thermal management and driver design are better than ​most​ of the alternatives I’ve tested. I’ve personally tested LED chips with a multimeter after a field failure (yeah, I’m that guy), and I can tell you: the failure is almost never the LED die itself. It’s the driver or the solder joint. Dialight uses potted drivers (fully encapsulated) on their industrial fixtures, which resists vibration and moisture better than open-board designs. If you’re wondering how to test an LED bulb with a multimeter for a driver failure, here’s a quick tip: set your multimeter to diode mode, and put the red probe on the anode, black on the cathode of the LED chip. If you see a voltage drop (usually 1.8-3.3V for most white LEDs), the chip is likely fine. If you get no reading or a short, the chip is dead. But honestly, for a Dialight fixture under warranty, I’d just call the distributor for a replacement. It’s not worth voiding the warranty with a multimeter unless it’s out of coverage.

Bottom line: would I spec Dialight again?

Over the past 6 years of tracking every invoice, I’ve learned that the cheapest option almost always costs you more in hidden expenses. Dialight isn’t the budget option, but for hazardous locations, outdoor durability, and long-term reliability, it’s been the right call for us. If you’re a small operation trying to make every dollar count, the Vigilant or Safesite lines are worth the upfront premium when you calculate TCO. I’m not saying it’s perfect for every application—if you’re just looking for a simple chandelier for a lobby, that’s a different conversation. But for industrial, commercial, and safety-critical lighting? It’s the investment that pays for itself.
