Treegers GL300W LED Grow Light | 300W | 825 µmol/s | IP66 | Full Spectrum | 1m² Coverage

Professional-Grade Light. Compact. Plug & Play.

The Treegers GL300W LED Grow Light is a serious grow light for growers who want serious results. At 300W with an 825 µmol/s PPF output and 2.8 µmol/J fixture efficacy, it delivers professional-level performance in a compact four-bar design that hangs, plugs in, and gets to work — no complicated setup required.

Rated IP66, built with passive cooling, and backed by a 3-year warranty, the GL300W is engineered to run hard, run clean, and last. Whether you're growing in a 1m² tent or a dedicated grow room, this light covers it all — evenly.

Why the GL300W Stands Out

• 💡 300W | 825 µmol/s PPF | 2.8 µmol/J efficacy — high-output, high-efficiency performance that rivals lights costing far more
• 🌱 Full-Spectrum Fusion — optimised spectrum for every stage from veg through to late bloom
• 📐 1.0 x 1.0m coverage — ideal footprint for a standard 1m² grow tent or dedicated grow space
• 🔆 Market-leading uniformity — strategically placed diodes with optional optical lenses distribute light evenly across the whole canopy, no hot spots, no dark corners
• 🛡️ IP66 rated — fully protected against dust and high-pressure water jets (12.5mm nozzle), built for demanding grow environments
• 💧 Silicone resin coating on all diodes — smooth, easy-to-clean surface that resists moisture and stickiness
• 🔥 Passive cooling heat sinks — no fans, no noise, no moving parts to fail
• 🎛️ 0–100% dimming — compatible with Treegers Precise T Dimmer (0-10V) for full light control
• 🔗 External controller ready — works with Treegers Growcast or any universal 0-10V controller
• ⏳ 60,000-hour LED bar lifespan — built to outlast many grow cycles
• 🏆 3-Year Warranty — backed by Treegers' quality guarantee
• ✅ AU certified — CE, SAA, RCM, RoHS, UKCA compliant

Outstanding Efficacy — At Every Point of the Canopy

Most grow lights quote peak efficacy at the centre of the beam. Treegers engineers for usable efficacy — meaning the 2.8 µmol/J figure holds up across the entire coverage footprint, not just the middle. With diodes rated up to 4.2 µmol/J, the GL300W extracts maximum photons per watt and delivers them where your plants actually need them.

IP66 — Built for Real Grow Environments

Humidity, water splashes, nutrient mist, dust — grow rooms are tough on equipment. The GL300W's IP66 rating means it's fully sealed against dust ingress and protected against high-pressure water jets. The silicone resin coating on every diode adds another layer of protection, and the smooth surface wipes clean easily between cycles.

Plug & Play. Scale When Ready.

The GL300W ships ready to hang and run — stainless cable hangers, power cable, and user guide all included. When you're ready to expand, it's compatible with the Treegers Growcast controller and any universal 0-10V dimming system for multi-light automation.

Perfect For

Serious home growers, hobbyist cultivators, and small commercial operations running a 1m² grow space who want professional-grade light output, IP66 durability, and full dimming control — without the complexity of a commercial installation.
