The SLTMAKS 4×4Ft High-End Series is our volume-purchase commercial LED grow light, built for the classic 4×4 ft footprint most flower rooms are planned around. It comes in 600W, 800W and 1000W builds on 6, 8 or 10 bars, delivering 1,740–3,000 µmol/s at 2.9–3.0 µmol/J. Every fixture runs a UL-listed Sosen driver with 0–10V dimming and RJ12/RJ45 daisy-chain control. One format covers veg, mixed-use and full flower, so a whole facility can run a single spares list.
When a facility buys forty fixtures at a time, the decision is what stays true across a whole pallet.
| Why choose the 4×4Ft High-End Series | |
|---|---|
| ⚡ Flagship efficacy, mainstream price | At 2.9–3.0 µmol/J you sit within a whisker of the Golden series, without paying for UV/IR channel hardware you may not run. For most flower rooms this is the efficiency sweet spot. |
| 🔌 UL-listed Sosen drivers | Drivers fail before LEDs do. Sosen is a publicly listed power supply manufacturer in the grow light industry, so driver quality is assured. We use this quality drivers, if failed, free replacement supported. |
| 🏗️ One footprint, three power steps | 600W for veg, 800W for mixed-use, 1000W for full flower. Same physical format, same hanging hardware, same control wiring, so racking, spares inventory and installation all simplify. |
| 🧩 Wide-Bar 1000W variant | A wide-bar configuration of the 1000W build is available in this series, documented in its own spec sheet on request. |
| 🎛️ 0–10V dimming, daisy-chain control | Dim by hand for one room or drive the whole run from a controller, with no proprietary hardware in between. |
One spectrum platform, configurable per order.
Every 4×4Ft High-End build ships a white-based full spectrum, customisable to your crop protocol under OEM/ODM. Tell us your target PPFD and crop stage at order time and we configure the spectrum accordingly.
We do not publish a generic spectral power distribution curve. Published curves are generic 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.
Values are the series range across the three power steps. Efficacy is verified per production batch on our in-house integrating sphere; the test report ships with the order.

| Where the 4×4Ft High-End fits | |
|---|---|
| 🌿 Commercial cannabis flower rooms | Full-cycle output at 2.9–3.0 µmol/J, the efficiency sweet spot for pallet-volume flower lighting. |
| 🔁 Veg, mixed-use and flower on one platform | 600W for veg, 800W for mixed-use, 1000W for full flower — same format, same hardware, one spares list. |
| 🏠 Standard 4×4 ft flowering rooms | The footprint most flower rooms are built around: one fixture, one hanger set, no overlap to manage. |
| 🏗️ Multi-row facilities | Buying by the pallet: one physical format across hundreds of fixtures simplifies racking, installation and spares. |
| 🌱 Rooms mixing with Golden | Many facilities run High-End in flower rows and Golden where UV/IR finishing matters — both on the same control platform. |
At full output on a 12/12 flowering photoperiod, a 1000W build draws about 12 kWh per day and a 600W build about 7.2 kWh. Dimming brings that down further, and the exact draw of your configuration is confirmed in the test report that ships with each order.
Send your room size and target PPFD, we reply with a fixture count, a layout and a configured quotation.
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.
Canopy footprint, ceiling height, aisle width, and whether the space is sealed or ventilated.
Veg or flower, and your target PPFD — we map which of the three power steps fits each zone.
You get a fixture count, wattage per fixture, bar configuration, and estimated canopy-level PPFD with stated assumptions.
Configured pricing, warranty term and lead time for your quantity.
For full-cycle flower at commercial target PPFD, one 800W–1000W build typically covers a 4×4 ft canopy; at lower targets or in veg, one fixture can stretch further or run dimmed. The honest answer depends on ceiling height, reflectivity and target PPFD — send the room and we will map it with stated assumptions rather than guess.
Same high-end components, different layout. This series runs the same configuration as the Advanced Golden series, Top-bin Samsung LEDs on a UL-listed Sosen driver, in a 4×4 ft format. Its heatsink bars are narrower and more numerous, so the diodes spread evenly across the whole canopy. The Advanced Golden series uses wide bars on a larger heatsink, which pushes PPFD and light intensity higher, and it sits at a higher price to match.
Contact us and we will send the detailed specification sheet for this variant, covering parameters, spectrum, PPFD distribution and the supporting test data.
Think of the driver as the engine of the fixture: without it, nothing runs. The LEDs only produce light while the driver supplies and regulates their current, so a driver failure takes down the whole fixture rather than a single diode. That is why the driver is the first component we specify on every build.
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.
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.
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.
Dimensions, ceiling height, and your current lighting if you have it. We reply with a layout, a PPFD estimate and a configured quotation.
