HortiBloom’s SOLO 300w is a first‑generation COB‑based LED grow light introduced in 2015. It pairs a single Cree CXA2540 COB (optional CXB3070) with 84 Bridgelux 5 W diodes and selectable veg/bloom channels. The fixture is designed for a 3 ft x 3 ft core footprint (about 90 x 90 cm) with total coverage up to 3.5 ft x 3.5 ft, using 90° or 160° lenses to tailor spread. Actual power draw is about 220 W at full power (60 W veg, 180 W bloom), providing a compact alternative to ~400 W HID in small tents. The fan‑cooled 36 x 36 x 8.5 cm housing weighs 5.7 kg and supports daisy‑chaining up to four units with UL‑rated drivers and standard hanging hardware included. HortiBloom notes this model was a best seller between 2015 and 2018.
