The HLG 300L Rspec was a second generation LED grow light produced by the Horticulture Lighting Group.
With it's 2 x Quantum Board 272 LED chip design with 16 additional red diodes per board it was one of the first high spec LED veg grow lights.
The HLG 300L was a step on in the evolution of the legendary HLG 300 V2.
Unfortunately this lamp is discontinued. Great news, we have something even better for you.
