The HLG 260W V2 QB RSPEC LED Kit is a powerful, energy-efficient, full-cycle lighting solution tailored for serious indoor growers. The system features two high-performance QB288 V2 RSPEC quantum boards, each densely packed with 272 top-bin Samsung LM301H LEDs plus deep-red 660 nm diodes, totaling 544 Samsung chips and 32 reds. These boards deliver exceptional photon efficacy (~2.6–2.7 µmol/J), enabling vigorous growth with significantly lower power draw and heat output. This kit includes a high-efficiency Meanwell / Inventronics LED driver (EUM-240 or XLG-240H), which supports dimming from about 30 W up to the full 260 W, giving growers flexibility to optimize light intensity for vegetative or flowering stages. But if you’re thinking about another more powerful or a different lighting system, then check out the HLG 650R or even the HLG Scorpion Diablo V2.
