The Two Gavita Giants: A Budget vs. Performance Showdown
I’m a procurement manager at a mid-size indoor farming operation. Over the past six years, I’ve managed a lighting budget of over $400,000 annually, negotiating with 12+ vendors and tracking every invoice in our cost system. When we decided to expand our facility in Q2 2024, the choice came down to two Gavita workhorses: the Pro 1700e LED (120-277V) and the Pro RS 2400e LED. Both are top-tier, but they’re not interchangeable. Here’s what the spreadsheets—and my gut—told me.
Before we dive in, let me clarify what this comparison isn’t. I’m not an electrical engineer, so I won’t pretend to know the intricacies of spectrum tuning. What I can tell you is how to evaluate these lights from a cost-of-ownership and operational-fit perspective. Let’s compare them across three dimensions: cost per photon, light distribution, and investment payback.
Dimension 1: Cost Per Photon – The Efficiency Head Fake
On paper, the 2400e looks like the clear winner in raw efficiency. It pushes about 2,400 µmol/s out of the box, while the 1700e delivers roughly 1,700 µmol/s. But that’s not the full story.
I compared quotes from three major suppliers (as of January 2025). A single Gavita Pro 1700e LED (120-277V) runs about $899 USD. A single Gavita Pro RS 2400e LED is priced at roughly $1,299 USD. At face value, the 2400e gives you more light per dollar: $1,299 / 2,400 = $0.54 per µmol/s, versus $899 / 1,700 = $0.53 per µmol/s. Almost identical.
But here’s the oversimplification trap: cost per photon ignores coverage and infrastructure. The 1700e is designed to cover a 4’x4’ footprint efficiently. The 2400e is a beast meant for a 5’x5’ area. In my facility, we run a 30’x30’ canopy. To cover that with 2400e units (5’x5’ spacing), we need 36 lights. With 1700e units (4’x4’ spacing), we need 56 lights.
Now, the numbers got interesting. 36 x $1,299 = $46,764 for the 2400e setup. 56 x $899 = $50,344 for the 1700e setup. The 2400e setup saves $3,580 in initial fixture cost. But my gut said wait—what about wiring, controllers, and installation?
Dimension 2: Infrastructure & Hidden Costs – The Real Story
This is where the cost controller in me got loud. The 1700e runs on a standard 120-277V input with a simple daisy-chain setup. Each fixture draws about 600W. Wiring 56 lights in parallel? Straightforward. The 2400e, however, draws nearly 1,200W per fixture. That means heavier gauge wire might be required, and definitely more careful load balancing on your electrical panels.
I won’t pretend to give you exact electrical cost data (that gets into territory I’m not qualified for), but I can tell you from experience that every time I’ve seen a facility choose the “bigger” light, the electrical install cost jumped by 15–25%. I asked two electricians for rough quotes on our 30’x30’ setup. Both said the 2400e system would add about $4,200–$5,000 in extra wiring and panel upgrades. That completely erased the $3,580 fixture savings.
The least expensive option often hides costs in the transformers.
There’s another factor: the 2400e is an RS (Remote Start) fixture, meaning it requires the Gavita controller for proper dimming and scheduling. The 1700e has onboard control, so for a basic setup, you don’t need the controller. For a 56-light 1700e setup, you could get away without one. For 36 lights of 2400e, the $800 controller becomes a required cost.
Dimension 3: Light Distribution & Crop Type – The Practical Fit
From the outside, it looks like two high-end lights covering similar canopies. The reality is their beam patterns are different. The 1700e uses a wide spread lens, giving you a more even distribution across its 4’x4’ zone. The 2400e has a more intense center beam, which is great for tall, bushy plants in a 5’x5’ footprint but can leave the edges weaker if your canopy is short.
I can only speak to our medium-height crops (think tomatoes, peppers). For our setup, the 1700e’s even spread gave us more uniform growth, which reduced our pruning time by roughly 8% per cycle—not a huge number, but it adds up over six cycles a year. The 2400e is probably better for tall, single-cola plants like cannabis, where penetration matters more than coverage uniformity.
The Verdict: What the Numbers Actually Said
After tracking every dollar, here’s my take:
- Choose the Gavita Pro 1700e LED (120-277V) if: You’re running a medium-height crop, you want to keep electrical install costs low, and you’re okay with a slightly simpler control setup. The total cost of ownership—including wiring and installation—was about $2,700 lower for our facility.
- Choose the Gavita Pro RS 2400e LED if: You’re growing tall plants in a 5’x5’ footprint, you’re already wired for higher current, and you plan to use the full Gavita controller ecosystem from day one. The potential yield boost from that intense center beam can justify the premium.
Both are fantastic lights. I’ve seen people assume the 2400e is “better” just because it’s bigger. But for our operation—and maybe for yours—the 1700e was the smarter financial call. Small doesn’t mean unimportant. The vendors who took my $5,000 order seriously six years ago are the same ones I’m now doing $200,000 annual contracts with. Don’t let anyone tell you that the lower-cost fixture isn’t professional-grade.
Final note: Pricing data is as of January 2025. Verify current rates at Gavita’s official distributor list, as prices and availability may have shifted. Your mileage may vary, especially if you’re dealing with different electrical codes or crop types.
