Pairs well with
The GL1000W+ is Treegers' top-of-range fixture — 1000W, 3090 μmol/s PPF, and 3.1 μmol/J fixture efficacy across a 1.5 x 1.8m canopy footprint. Ten magnetic easy-click LED bars on a flat-pack modular frame, driven by a single high-grade 1000W driver, with passive cooling that runs completely silent and IP66 protection that keeps your investment intact. This is the fixture for growers who are serious about yield, efficiency, and longevity — backed by a 5-year manufacturer warranty that reflects just how much confidence Treegers has in it.
Tech Specs
What's in the Box
- The GL1000W+ requires 180–277V input — it is not compatible with standard 120V circuits. Confirm your power supply before ordering.
- At 13.5kg, this fixture needs a solid, load-rated hanging point. Confirm your tent or ceiling mount is rated to handle the weight before installation.
- A controller is required for dimming — the Treegers Precise T Dimmer or Growcast both connect via the LLT M12 port. Without one, the fixture runs at full 1000W output only.
- The driver is remote-mounted using the included support brackets — positioning it outside the canopy area improves passive cooling performance.
- Need more distance between the driver and the fixture frame? The GL1000W+ Driver Extension Kit (sold separately) gives you 3 metres of clearance.
How to Set Up the GL1000W+
Pairs Well With
At 1000W, automated scheduling and PPFD targeting pay serious dividends. The Growcast is the recommended controller for the GL1000W+.
Treegers Precise T DimmerFor growers who prefer manual control, the T Dimmer connects directly to the GL1000W+ via the LLT port for simple 10% step dimming.
Treegers GL1000W+ Driver Extension KitNeed more distance between the driver and the frame? The 3-metre extension kit gives you placement flexibility in larger rooms.
Treegers Fixture Link CableRunning multiple GL1000W+ fixtures from one Growcast? One Fixture Link Cable per additional light chains them all together.
Treegers Quantum PAR MeterMapping a 1.5 x 1.8m canopy at 3090 μmol/s — you need measured data to dial this light in properly. The PAR Meter gives you the numbers.
Inline and Exhaust Fans1000W requires serious ventilation. Size your inline fan to handle the thermal load — this fixture demands a properly spec'd extraction setup.
Frequently Asked Questions
What voltage does the GL1000W+ require?
The GL1000W+ requires 180–277V input and is not compatible with standard 120V circuits. In Australia, standard single-phase power is 230V, which falls within the rated range. If you are running the fixture in an unusual electrical setup, confirm your supply voltage before ordering. Contact The Grow Guys if you need guidance.
What is Full-Spectrum HybridF+ and how is it different from Full-Spectrum Fusion?
Full-Spectrum Fusion (used on the GL300W and GL420W) is a balanced spectrum designed equally well for veg, propagation, and flower across all growth stages. Full-Spectrum HybridF+ (used on the GL650W+ and GL1000W+) adds a Deep Red enhancement that biases the spectrum toward flowering — making it the better choice for growers pushing maximum yield from mature, flower-stage canopies. Both spectrums support full-cycle growing, but HybridF+ is tuned for heavy-flowering performance.
Does the GL1000W+ come with a dimmer or controller?
No — a controller is sold separately. The GL1000W+ connects to the Treegers Precise T Dimmer, the Treegers Growcast, or any universal 0–10V controller via the LLT M12 control port. Without a controller connected, the fixture runs at full 1000W output. For a fixture at this power level, we strongly recommend the Growcast for proper scheduling and ramp control.
How does the modular design work, and can individual bars be replaced?
Yes — the GL1000W+ uses ten magnetic easy-click LED bars that attach to and detach from the frame without tools. If a bar is damaged or needs servicing, it can be replaced individually without returning the entire fixture. This dramatically reduces downtime and replacement cost compared to panel-style fixtures. Contact Treegers support directly for individual bar replacement parts.
Does passive cooling work at 1000W?
Yes — the 3.1 μmol/J efficacy means the GL1000W+ converts a very high proportion of its input power into usable light rather than heat, which reduces the thermal load on the heat sinks relative to less efficient fixtures. Ensure your grow room has adequate air movement and that the driver has its own airflow — the driver generates heat regardless of how efficient the bars are.
What warranty does the GL1000W+ carry?
The GL1000W+ carries a 5-year manufacturer warranty from Treegers — the longest warranty in the Treegers fixture range. Note that the warranty does not cover damage from high sulphur environments, as sulphur-based products can cause diode vulcanization. If you use airborne pesticides or fertilizers, take precautions to keep the fixture protected.
