LED Module Series — 800W–1200W 1:1 HPS Replacement LED Grow Lights

Better light, same room, no rewiring. The LED Module Series replaces HPS 1:1, so a conversion never touches your electrical layout, and swaps the narrow HPS output for a full spectrum with red, blue and IR that carries a crop from veg through flower. Choose 800W or 1200W across three housing styles, including a Gavita 1900E form factor and a wide-emission build that spreads light more evenly across the canopy. Top-bin Samsung / SMD Leds on a UL driver, dimmable and daisy-chainable. ETL and DLC listed.

Why Choose the LED Module Series

Retrofit projects have different constraints than new builds. This series is designed around them.

Why choose the LED Module Series
🔁 1:1 HPS replacement, no rewiringA direct replacement for the fixture already on your ceiling. We map your existing HPS layout to a 1:1 LED plan, including the heat-load delta, so the conversion needs no rewiring of the room before you commit.
🌈 Full spectrum with red, blue and IRThis fixture runs a full spectrum with red, blue and IR output in place of the narrow HPS band, so the whole plant cycle runs on one light. Red carries photosynthesis and flower development, blue keeps vegetative growth compact and structured, and IR supports the far-red response that finishes a canopy.
⚡ LED energy savings, long life2.8–3.1 µmol/J cuts the running power against the HPS load it replaces, and the diodes are rated beyond 50,000 hours.
🧱 Modular, dimmable, daisy-chainableModules are the service unit, so you swap a module rather than the fixture and hold fewer spares per megawatt installed. Dimming and daisy-chain control run on the same platform as the rest of the range.
✅ ETL, DLC certifiedListed for the North American market, with test documentation supplied per order.

Spectrum

Red, blue and IR in one fixture, tuned for the whole plant cycle.

The LED Module Series uses a full spectrum with dedicated red, blue and IR output. Red drives photosynthesis and flower development, blue keeps vegetative growth compact and well structured, and IR supports the far-red response that shapes how a canopy stretches and finishes. Because all three are built into the same fixture, one light carries a room through the whole cycle from veg to flower.

Against the narrow HPS band it replaces, this spectrum delivers more usable light per watt, which is where the 2.8–3.1 µmol/J efficacy and the lower running cost of the series come from. Under OEM/ODM the spectrum can be tuned to your crop protocol and matched to the light already in your building, so a retrofitted room sits in the same spectral envelope as the rest of your LED estate.

We do not publish a generic spectral power distribution curve, because published curves are catalogue graphics rather than a measurement of this fixture. A measured spectral report for your configuration is available on request and ships with the order.

Pro tip. Converting from HPS in phases? Convert the highest-running-hours room first, because the energy saving per room pays for the next phase faster than converting everything at once.

Specifications

Values apply to both power steps. Efficacy is verified per production batch on our in-house integrating sphere; the test report ships with the order.

Application Scenarios

Where the LED Module Series fits
🔁 HPS-to-LED retrofits1:1 replacement mapping on existing layouts, wiring and service infrastructure, with no rebuild required.
🏭 347–480V commercial sitesWide voltage input covers industrial supplies common in older commercial buildings.
🧱 Phased conversion projectsConvert room by room on one product line, mixing LED and legacy HPS while the project runs.
🔧 Maintenance-conscious operationsModular construction: swap a module, not the fixture, and hold fewer spares.
🌿 Commercial cannabis and greenhouseFull-spectrum output for flower rooms and supplemental greenhouse regimes alike.

Energy Snapshot

At full output on a 12/12 flowering photoperiod, a 1200W build draws about 14.4 kWh per day and an 800W build about 9.6 kWh, a fraction of the HPS load it replaces once the heat-load delta is included. The exact draw of your configuration is confirmed in the test report that ships with each order.

Sizing an LED Module Retrofit

We do not publish a generic PPFD table, because the same fixture reads very differently at 12 in and at 36 in, over reflective walls or open aisles. Instead, send your room and we return a layout.

Room dimensions

Canopy footprint, ceiling height, aisle width, and whether the space is sealed or ventilated.

Existing lighting

Send your current fixture count, wattage and layout, and we map the LED replacement, including the heat-load delta.

Fixture map

You get a fixture count, wattage per fixture, bar configuration, and estimated canopy-level PPFD with stated assumptions.

Quotation

Configured pricing, warranty term, and the lead time for your quantity, confirmed in writing.

FAQ

Does it really replace HPS 1:1?

In most rooms, yes. The module is designed as a 1:1 HPS replacement on existing layouts, so the fixture count and the wiring stay as they are. We map your fixture count and wattage to the LED plan with the heat-load delta stated before you commit: the layout plan, not a guess, is what sizes the retrofit.

What voltage does it accept?

AC 100–277V as standard, with 347–480V available for commercial and industrial sites. Tell us your service voltage with the quote request and we confirm the configuration.

Is it dimmable and controllable?

Yes. The series runs dimming and daisy-chain control on the same platform as the rest of our range, so retrofitted rooms join your existing control infrastructure.

Where does this series ship from?

This series ships factory-direct from our Dongguan plant. Production runs 15–35 days depending on quantity, and the lead time for your configuration is confirmed with the quotation.

Can I get a custom spectrum, my own logo and my own housing colour?

Yes. OEM/ODM covers spectrum, PPFD target, logo, LED brand, housing colour, driver, style and design, plus optional smart controllers and apps. Samples are typically ready in 1–5 days and mass production runs 15–35 days depending on volume.

What is the warranty and what does it cover?

Up to 5 years optional, model-dependent, covering the fixture and driver. Terms are stated on the quotation so there is no ambiguity at delivery.
