Service access is the point of the External Driver Series: the driver sits outside the bar, clear of canopy heat, so a failed power supply is a plug-in swap instead of a fixture change, and the fixture body hangs lighter. Five steps run 600W, 640W, 800W, 1000W and 1600W across 4×4, 4×6 and 4×10 ft frames, up to 4,480 µmol/s on the 16-bar 1600W build, the largest fixture we manufacture. Samsung LEDs on UL-listed Sosen drivers, with OSRAM, Epistar or Ledestar diodes selectable under OEM/ODM. ETL, CE and RoHS certified.
A series designed around the component that fails first, and the labour it costs you.
| Why choose the External Driver Series | |
|---|---|
| 🔧 Serviceable external driver | The driver mounts outside the bar, carried on the back of the fixture body and clear of canopy heat. Because it is a separate plug-in unit, a failed power supply is replaced with the fixture left hanging: less downtime, less scaffolding, less labour per service call. |
| 🏗️ Three frame sizes, one series | 4×4, 4×6 and 4×10 ft frames from 600W to 1600W, so small rooms and long bays run the same platform and spares list. |
| ⚡ Five power steps | 600W / 640W / 800W / 1000W / 1600W across 6 / 8 / 10 / 16 bar configurations, up to 4,480 µmol/s. The 1600W build on a 4×10 ft frame is the largest fixture we make. |
| 🎛️ 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. |
| ✅ ETL, CE, RoHS certified | Certified for the usual North American and European import requirements, with test documentation supplied per order. |
One spectrum platform, configurable per order.
Every External Driver build ships a white-based full spectrum, customisable to your crop protocol under OEM/ODM. Tell us your crop stage and target PPFD at order time and we configure the build 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We do not publish a generic spectral power distribution curve.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 five power steps. Efficacy is verified per production batch on our in-house integrating sphere; the test report ships with the order.

| Where the External Driver Series fits | |
|---|---|
| 🌿 Commercial cannabis flower rooms | Full-cycle output from 4×4 ft rooms to long 4×10 ft bays on one series. |
| 🔧 Service-first operations | Facilities that plan maintenance in minutes, not hours: drivers swap without taking fixtures down. |
| 🏗️ Long-bay rooms | The 4×10 ft 1600W build covers extended bays with fewer hangs per fixture. |
| 🔁 Mixed facilities | Same control platform as the rest of the range, so the series mixes cleanly with our other fixtures. |
| 🍅 Greenhouse supplemental | Wide 0–10V dimming makes the fixture easy to blend with daylight in greenhouse regimes. |
At full output on a 12/12 flowering photoperiod, a 1600W build draws about 19.2 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.
Send your current fixture count and wattage, and we map the replacement, including the heat-load delta.
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.
Service access. The driver is the component most likely to need attention before the LEDs do. It sits outside the bar, carried on the back of the fixture body, so a failure becomes a plug-in swap with the fixture left hanging rather than a fixture change, and the electronics stay clear of canopy heat. Across a large facility that difference compounds with every fixture and every year of operation.
Lower steps (600–1000W) serve the 4×4 and 4×6 ft frames; the 1600W build serves the 4×10 ft frame, our largest fixture. The layout plan maps the right step to your room before you commit.
Yes. UL-listed Sosen is standard, and under OEM/ODM the driver brand and specification can be configured to your market and certification requirements. Tell us what you standardise on and we quote accordingly.
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.
