HortiBloom LED’s Mega 300 is a two‑bar, passively cooled LED grow light released in October 2018. It draws 300 W and is specified for a 4' x 2' (120 x 60 cm) core coverage. The fixture uses 336 Osram Duris S5 3030 LEDs, with an optional Samsung LM301 configuration, and lists 800 µmol/s PPF at up to 2.4 µmol/J efficiency. Dimensions are approximately 90 x 30 x 9 cm, with a 9 kg weight. The design uses UL drivers, no fans, and adjustable viewing angle hardware. Input voltage is AC 100–270 V. Intended for full‑cycle cultivation, the Mega 300 targets even PPFD over its footprint while serving as a compact alternative to 600 W HID in similar spaces.
