GL420W Tactical Advantages
Technology & Design
Innovative and revolutionary multi-linear plug & play design 4 Bar LED. Quality, high performance LED diodes with industry leading LED drivers, provide the ultimate in performance and reliability. High grade heat sinks and optimal passive cooling throughout fixtures, ensures the extended lifespan of all components, preventing premature diode decay.
Usable Photon Efficacy
Very high light output of 1155 μmol/s PPF with fixture efficacy of up to 2.8 μmol/J, utilizing diodes with an efficacy of up to 4.2 μmol/J. Treegers LED fixture technology offers remarkable usable efficacy across each point of the lights footprint/coverage area
Uniformity
By using a combination of strategically placed LED diodes and optical lenses, our unique hybrid designs provide market leading uniformity, distributing light evenly across the whole canopy/coverage area.
IP66 & Smooth Resin Coating
Treegers LED fixtures are rated at IP66. Meaning full protection against high pressure water jets (12.5mm) and total dust ingress. Utilizing innovative silicone resin protection on all diodes and watertight connections on all cables. Our unique coating, besides providing optimal protection for all LED bars, also ensures a smooth surface, with reduced stickiness making it very easy to clean.
Longevity & Consistency
Treegers LED fixtures are designed to minimize degradation, with less than 10% light decay over 5 years. Optimized thermal management, premium diodes, and precise power control prevent overdriving, ensuring long-term efficiency. Tested under extreme conditions, our LEDs retain over 91% output at 50,000 hours—delivering consistent light intensity, superior yields, and maximum ROI.
