The Mars 300w CREE COB LED grow light by Mars Hydro delivers full-spectrum lighting for every stage of plant growth, from start to finish. Featuring a CREE COB LED 3590 core with red, blue, and OSRAM 660nm LEDs, the light fixture delivers powerful, balanced light distribution, reaching 532 μmol (PAR) at 18” (45 cm) from the canopy while only consuming 110W, replacing a 250W HPS/HID light bulb, thus saving up to 80% in energy costs. With a core coverage of 2.5 ft. x 2.5 ft. (70x70 cm) and maximum coverage of up to 4.5 ft x 4.5 ft (140x140 cm), the Mars 300w CREE COB LED grow light by Mars Hydro is completely silent thanks to its fanless heat sink that keeps it whisper-quiet while operating, making it a perfect choice for indoor growers seeking efficiency and performance. The Mars 300w CREE COB LED is perfect for covering 75x75cm veg and 130x130cm flower areas. Need more coverage?
