Horticultural LED Grow Lights from China
1 resources tagged with "Horticultural"
Horticultural LED grow lights from China are spec'd on photon efficiency (PPE) and spectrum, not raw wattage — commercial fixtures in the 200W–1000W range now hit 2.5–3.0 µmol/J using Samsung LM301H or LM301B diodes, which is the number cannabis growers and vertical farms actually compare. The pitfall is a factory quoting wattage while using cheaper diodes that deliver lower PPE, so a 600W light underperforms a properly-binned 480W one. When we source these we verify the diode brand and bin, the driver (Mean Well is the common quality reference), and ask for an independent PPF test report rather than the factory's own figure.
A horticultural LED grow light is a full-spectrum fixture engineered to deliver photosynthetically active photons efficiently. The buyer pitfall is comparing fixtures by wattage instead of PPE (µmol/J) and PPF (µmol/s) — two lights at the same wattage can differ 30% in usable light, so always compare on photon metrics backed by a test report.

FAQ
What PPE should a good commercial grow light hit?
Quality commercial fixtures using Samsung LM301H or similar top-bin diodes reach about 2.5–3.0 µmol/J. Below roughly 2.3 µmol/J you are usually looking at cheaper diodes or an inefficient driver, regardless of the advertised wattage.
What certifications do grow lights need for the US and EU?
US sale generally needs ETL or UL safety listing and FCC for EMC; EU sale needs CE plus RoHS. Drivers from a reputable brand (e.g. Mean Well) make certification cleaner because the driver is the part most scrutinized for safety.
What MOQ and lead time are typical?
Custom-branded commercial grow lights usually start around 100–500 units, with stock models available in smaller quantities. Lead times run roughly 3–5 weeks, longer if you specify custom diode binning or a custom spectrum.
