I manage the purchasing for a medium-sized greenhouse operation—roughly 30,000 square feet of mixed vegetable production. Every spring, I get the same question from our head grower: "Should we upgrade to the Gavita Pro 1700e LED for the new wing, or stick with a hybrid setup?" There's no single answer. It depends on your crop, your ROI timeline, and—honestly—your tolerance for risk.
Here's the framework I use after several rounds of decision-making (and one expensive mistake I'll get to). I'll walk through three common scenarios and how the Gavita Pro 1700e LED price vs. value equation plays out differently in each.
Scenario A: You're Building New Infrastructure
If you're starting from scratch—new benches, new wiring, new everything—the argument for Gavita's Pro series LEDs is strongest. You're not replacing anything; you're designing for efficiency from day one.
Why this is the easiest case for the Pro 1700e
The upfront cost of a Gavita Pro 1700e LED is roughly $1,100–$1,400 per fixture (pricing as of Q4 2024). Compare that to a 1000w DE HPS fixture at about $250–$400. The sticker shock is real. But when you factor in installation costs, the math shifts.
What I mean: HPS requires 208–277V wiring, separate ballasts, reflectors, and—for the 1000e DE—you need the lamp and ballast separately. The 1700e is a self-contained unit. You run one power cable, mount it, and you're done. In our 2024 build-out, we calculated the labor savings alone covered about 15% of the LED premium.
The real delta, though, is electricity. At $0.12/kWh, running a 1000w HPS for 14 hours/day, 365 days/year costs about $613 per fixture annually. The Pro 1700e uses about 645w at full power—roughly $395 per year. That's a $218 savings per fixture, per year (note to self: verify current local rates; prices have changed since our 2024 budget).
Verdict for this scenario: If you're building new and have a 3–5 year horizon before your investor calls you greedy, the 1700e is a solid bet. The payback—comparing installed cost vs. operating cost—comes in around year 4 or 5. After that, it's pure savings.
Scenario B: You're Retrofitting an Existing HPS Setup
This is where I got burned once. The upside was saving money on electricity. The risk was disrupting a working production cycle. I kept asking myself: is $20,000 in annual power savings worth potentially tanking a grow cycle because the light spectrum was different?
Turns out, yes—if you do it right. But 'right' means over a transition period.
The incremental approach I'd recommend
Don't swap all fixtures at once. We replaced one 30x30 foot bay with the Gavita Pro 1700e LED while leaving the adjacent bay on HPS. This let us run side-by-side comparisons for one full crop cycle.
What we found:
- The LED bay used 38% less electricity
- Yield was comparable—slightly higher in the LED bay during summer (less heat stress)
- Heat management changed: we had to adjust our HVAC schedule because LEDs emit less radiant heat than HPS
But here's the catch (and the part I wish someone had told me earlier): the Gavita Pro 1000e bulb is not the same as the Pro 1700e. If you're comparing the Pro 1000e DE lamp (still HPS, double-ended) to the LED, the 1000e DE is a workhorse. It's cheaper to buy ($250 per bulb) but consumes more power. The 1700e outperforms on efficiency, but the upfront difference is $1,100 vs. $250. (ugh).
Looking back, I should have started with a smaller LED retrofit and scaled based on data. At the time, the vendor pitch made the transition sound seamless. It wasn't—but it was worth it once we dialed in the environment.
Verdict for this scenario: Start with 10–20% of your fixture count as LED. Run two cycles. Collect your own data. Then decide whether to go all-in. And whatever you do, factor in HVAC adjustments—that cost can eat into your energy savings if you're not careful.
Scenario C: You're Budget-Constrained (or Skeptical About ROI)
This is the toughest scenario. I've been there. The Gavita Pro 1700e LED price feels like a luxury when you're trying to keep your average cost per gram down. Or when your CFO asks "Why is this light more expensive than a whole grow tent setup?"
In this case, I'd say: don't buy the 1700e. At least not yet.
Alternatives I've considered
If you're price-sensitive but still want LED, the Gavita CT series (CT 1930e) or even the E-Series (which is less powerful) can be had for $600–$900. They're not as efficient as the Pro 1700e, but they still beat HPS on power draw.
(Which, honestly, might be the smarter move if you're testing the waters.)
Or—here's the contrarian take—stick with the Gavita Pro 1000e DE bulb setup for another year. The bulb is a known quantity. It's cheap to replace ($35–$50 every 12–18 months). It produces massive PAR output. The heat is a problem in summer, but manageable if you have good ventilation. And the upfront cost is low enough that you can invest the savings in other areas—better climate control, CO2 enrichment, genetics.
I have mixed feelings about this advice. On one hand, I'm basically telling you to skip the more efficient option. On the other, I've seen operations overextend on LED hardware and then underinvest in other critical inputs. A balanced setup with HPS and a few LED islands might beat a full-LED room with compromised HVAC. (Note to self: this is worth testing systematically in 2025.)
Verdict for this scenario: Don't let the perfect be the enemy of the good. If budget is tight, buy one 1700e as a test unit, but spend your main budget on proven HPS infrastructure. Upgrade when you have data and cash flow, not before.
How to Decide Which Scenario Is Yours
Here's a quick litmus test I've been using since my 2023 debacle:
- Are you building from scratch? Go LED. Get the Gavita Pro 1700e. The total cost of ownership favors it.
- Are you retrofitting and can afford a phased approach? Replace 10–20% of your HPS with LED. Run comparisons. Extrapolate.
- Are you undercapitalized or running on thin margins? Stick with HPS or a lower-tier LED line. The Pro 1700e is an investment, not a commodity. Don't budget-stretch for it.
One last thing: whatever light you choose, make sure it's compatible with your controller. Our integration with TrolMaster was flawless on the 1700e, but the adapter cable added $30 per fixture to the BOM. Small things like that add up.
If you're still unsure, drop me a line. I've made most of the mistakes already—happy to save you the tuition fee.
