Welcome to the Lumatek 680W GH Top Light series, featuring both the White + Red and Red + Blue models—two high-performance LED fixtures engineered specifically for greenhouse applications. These advanced lighting solutions are designed for professional growers looking to transition from traditional HPS systems to more energy-efficient, spectrum-optimized LED technology without compromising light intensity.
For those aiming to maintain current light levels while significantly lowering operational expenses, the 680W GH Red + Blue model is the ultimate 1:1 HPS replacement. It delivers an exceptional photon efficacy of up to 3.4 µmol/J and a powerful PPF output of 2285 µmol/s, helping growers reduce energy consumption by up to 40%. Enhanced with special integrated optics, this fixture provides superior light uniformity and distribution across the canopy, promoting consistent growth and maximizing yields.
Equally innovative is the 680W GH White + Red model, tailored for vegetative growth stages, low-PPFD flowering, and vinery crops. It produces a balanced spectrum featuring blue, red, and beneficial green wavelengths, which contributes to deeper canopy penetration and improved plant development throughout the year. With an efficacy of 2.7 µmol/J and a PPF output of 1805 µmol/s, this fixture offers growers an efficient and tailored solution for specific crop cycles and growth objectives.
Both models share a rugged, compact housing and feature passive thermal management for quiet, reliable performance. Designed to meet the highest industry standards, these LED fixtures include 0–10V dimming, compatibility with Lumatek or universal controllers, and daisy-chain capability for scalable installations. Operating on 277–440V AC input with a power consumption of 680W (1.98 A @ 380V AC), they boast a power factor above 0.98, ensuring stable energy use.
Each unit weighs 8.8 kg, measures 654 x 254 x 118 mm, and carries an IP65 rating for protection against dust and water ingress. Certified for CE, EMC, and LVD compliance, they adhere to international standards including IEC 60598-1 (-2-1), EN IEC 620312, EN 62471, and EN 62493, and feature Class I electrical insulation. With a lifetime rated at L90 > 50,000 hours and backed by a 3-year warranty, the Lumatek 680W GH Top Light series offers a reliable, high-efficiency solution for professional greenhouse growers looking to improve results and reduce costs year-round.
