HM Quantum Board 100W Eco

HM Quantum Board 100W Eco by Harvest Master is a compact, dimmable LED grow light based on a 30x24 cm quantum board. The HMQB1WE model uses Samsung 281B plus Epistar diodes (222 pcs) in a full-spectrum array combining 3000K and 5000K white with 660 nm deep-red and 730 nm far-red. Power consumption is 100 W with a built-in dimmer, it operates on 100–240 V, and is rated at 2.75 μmol/J efficacy. The passively cooled board weighs 1.3 kg and is specified for a service life above 30,000 hours. Pairing guidance from the brand’s 60×60×160 cm tent (recommended for 100–200 W LEDs) indicates an effective single-fixture coverage around 60×60 cm. This configuration suits seedlings, veg, and small flowering canopies in micro or starter grow spaces.
