Proven in Production
Running in commercial greenhouses today
These are not showroom photos. Fixtures from this program are installed and commissioned in large-scale glasshouse operations, with our partner engineers on site.
🍅 Commercial tomato glasshouse
Deployment 01 — Russia
High-wire tomato, year-round supply
Supplemental toplighting commissioned across a commercial tomato glasshouse — engineered light plan, on-site commissioning visit, and photometric verification with the growing team.
- High-red toplight spectrum for fruiting crops
- Uniform PPFD across the growing rows
- Commissioned together with the client's agronomists
Deployment 02 — Russia
Cucumber glasshouse, supplemental toplighting
A second commissioning project: LED toplights installed over cucumber rows in a large glasshouse complex, balancing natural daylight with red-rich supplemental light through the dark season.
- Toplights mounted on existing trellis structure
- Fixture-level commissioning and aiming on site
- Follow-up visit documented with the grower

FAQ
Grow lighting questions, answered
What buyers and growers ask us before their first order.
Are these grow lights suitable for large commercial greenhouses?
Yes. The toplight series runs 520–1210 W at 120–277 / 277–480 Vac with IP66 protection and Type III/IV optics designed for high-wire greenhouse crops — and the same fixtures are already running in large commercial tomato and cucumber greenhouses supplied through this program.
What efficacy do the LED fixtures reach?
Depending on series and configuration, photon efficacy ranges from 2.5 to 3.4 µmol/J. Toplights can be ordered with PPE tuned between 2.7 and 3.4 µmol/J to match your light plan and budget.
Can spectrum, wattage and dimming be customised?
Yes. Spectra are available in high-red, full-spectrum, and full-spectrum with far-red or UV; dimming options include knob, 0–10 V and wireless WiFi control; and OEM / private-label branding is supported for volume buyers.
What certifications and warranty do the lights carry?
Fixtures are CE marked, with SGS and RoHS documentation available and ETL listing on selected HID models. LED toplights carry up to a 5-year warranty with rated lifetimes up to 50,000 hours. We add an independent pre-shipment quality inspection on every order.
Do you supply a complete grow-room control system?
Yes. A WiFi or wired smart control system links the lights with PH, EC, CO2, quantum (PPFD), lux and temperature-humidity sensors, so lighting, irrigation, climate and CO2 can be automated from one phone app or central controller.
How does buying through Zhoukun Group work?
Send your crop, growing area and target PPFD — or an existing light plan. You'll receive a fixture recommendation and factory-direct quotation, samples on request, independent QC before shipment, and consolidated export logistics to your port. One English/Russian/Chinese-speaking team from enquiry to delivery.
Planning supplemental lighting or a lighting product line?
Send your crop and growing area — or your target retail range — and we'll reply with fixtures, factory-direct pricing and lead times.
