Maxsisun is a Chinese-led horticultural lighting brand founded in 2009, and its mission has been clear from the start: to make high-quality LED grow lights both powerful and affordable for everyday growers. Early on, the company focused on combining Samsung LEDs and Mean Well drivers, components typically found in premium fixtures, allowing them to deliver robust, full-spectrum lighting at budget-friendly prices. Operating out of China with local warehouses in the U.S., Maxsisun built its reputation around value-driven products backed by dependable warranties and responsive support. Their product ecosystem centers around two standout lines: the PB Pro Series, featuring models like PB1000, PB1500, PB2000, and the flagship PB4000, and the MF Quantum Boards such as the MF1000 and MF2000. The PB4000, for example, runs at a steady 400 W and delivers up to 1,870 µmol/s of PPF thanks to its efficient design and passive cooling. Meanwhile, the MF2000 quantum board, using hundreds of Samsung chips, achieves around 2.0 µmol/J at just 230 W and supports remote dimming and daisy-chaining, ideal for a 4‑by‑2 ft grow tent. From their 2009 beginnings to their mature PB and MF series, they’ve delivered energy-efficient, full-spectrum LED fixtures, equipped with features like remote dimming, multi-stage control, and reliable post-sale support.
