1,990 photons per second from 640 watts. 3.1 µmol/J efficiency, full spectrum, full cycle.
The Photontek X 600W PRO 3.1 puts Samsung LM301H EVO and Osram 4.24 diodes into a six-bar aluminum frame that covers a 5x5 ft canopy at 120 degrees of spread. It draws 640 watts, outputs 1,990 µmol/s of photosynthetically active light, and dims from 100% down to off without losing efficiency at any point in the range. Photontek is the North American arm of Lumatek, which has been building drivers and fixtures for commercial growers in Europe for over a decade. Backed by a 5-year warranty, IP65 rated, and assembled without tools.
Upgrading from the X 600W PRO (2.7) or 2.9? The 3.1 uses the same frame and hanging hardware but outputs 19% more photons at the same wattage. Your existing Photontek Digital Controller, dimmer, and power cables are all compatible. If you're running the older version and want more light without adding a second fixture, this is the direct upgrade path.
- 2.0 to 2.5 µmol/J efficacy from lower-bin diodes
- Bars soldered to the frame, no way to remove or replace one
- Driver fixed to the fixture, all heat stays in the tent
- Basic knob dimmer only, no external controller support
- No moisture protection, exposed diodes collect dust and corrode
- 1 to 3 year warranty, limited or no driver coverage
- 3.1 µmol/J from top-bin Samsung LM301H EVO and Osram 4.24 diodes
- Magnetic snap-in bars, hot-swappable without powering down
- Detachable driver mounts outside the grow space to reduce heat
- 0-10V universal control, daisy chain up to 100 fixtures
- IP65 rated with clear glue protection at 99% light transmittance
- 5-year full warranty covering driver, bars, and frame
Two diode families, one full spectrum: how the 3.1 makes light
The X 600W PRO 3.1 combines two types of LEDs on every bar. Samsung LM301H EVO white diodes produce a broad-spectrum base covering blue, green, and red wavelengths. They are Samsung's latest top-bin horticultural diode, selected for the highest photon output per watt in each production run. Osram 4.24 deep-red diodes supplement the spectrum with a concentrated peak around 660nm, which is the wavelength most efficiently absorbed by chlorophyll during flowering and fruit set.
The two diode types are mixed across all six bars so every square inch of canopy receives the same ratio of wavelengths. Each bar runs at roughly 100 watts, keeping junction temperatures low, which extends diode life and maintains output. A clear glue protection layer covers every diode with 99% light transmittance (vs. 95 to 97% for traditional conformal coatings), while also sealing the bars to IP65 against moisture and dust.
19% more photons than the previous generation, same frame 3.1 µmol/J
The jump from the 2.7 version (1,620 µmol/s) to the 3.1 (1,990 µmol/s) comes entirely from newer diodes and an improved driver, not a larger fixture. That 370 extra µmol/s is enough to push a 4x4 coverage area out to a true 5x5 without light-starving the edges.
Magnetic snap-in bars: run 1, 3, or all 6 Hot-swappable
Each 100W bar clicks into the frame with magnets and quick-release connectors. No wiring, no screws. You can remove or add bars without powering down the fixture, so you can scale light coverage as your canopy fills out.
Detachable driver moves heat outside your grow space
The driver generates the fixture's thermal load. Detaching it and mounting it outside the tent or room drops the in-canopy BTU output from 2,201 to 2,047 BTUs/h. In a sealed tent, that difference can save you a degree or two at the canopy.
0-10V universal control, daisy chain up to 100 fixtures
The included 5-step dimmer handles most home grows. For automated scheduling, sunrise/sunset ramping, and 1% dimming increments, the optional Photontek Digital Controller connects via 0-10V and manages up to 100 fixtures. Any third-party 0-10V controller also works, and an RJ-to-0-10V adapter is available for systems with RJ ports.
Full cycle spectrum with no bulb swaps or channel switching
The fixed spectrum is weighted heavily toward red, which drives strong flower response, while retaining enough blue for compact, healthy vegetative growth. There is no UV or far-red on the fixture itself. Photontek sells a 50W far-red supplemental bar separately for growers who want Emerson enhancement effect coverage.
5-year warranty with Lumatek's track record behind it
Photontek is Lumatek's North American brand. The drivers, diode binning, and quality control all come from the same engineering team that has supplied European commercial facilities for years. The 5-year warranty covers the driver, bars, frame, and all included components.
Unbox it, snap it together, hang it, grow.
Snap the frame together
The aluminum frame connects with quick-release fittings. No tools or hardware needed. Most growers have the frame locked rigid in under a minute.
Click in the LED bars
Each bar hooks into one side and magnets to the other, making the electrical connection automatically. Start with fewer bars for seedlings, add more as the canopy expands.
Mount the driver and plug in
The driver sits on top of the frame by default, but it detaches so you can mount it outside the tent to move heat out of the canopy. Both 120V (NEMA 5-15P) and 240V (NEMA 6-15P) power cables are included.
Hang, set height, and dial in your intensity
Use the included metal cable hangers to suspend the fixture. The manual includes a PPFD chart with recommended heights and dimmer settings for each growth stage. Start lower than you think and increase gradually.
